PCLinux OS on Intel 82845 chipset

PCLinux OS is a very user friendly Linux Distribution which I have not tried since long. I am bored with Ubuntu Karmic and most mainstream distributions since the desktop I am using at present has Intel 82845 chipset which has problems with all these distributions because the problem lies with the latest intel driver. When I looked at PCLinux OS it has X.Org X Server 1.4.0.90 built in 2007 and I thought it should work on this machine.

I decided to have a look at their LXDE Live CD and downloaded the iso. I mounted the iso and copied vmlinuz and initrd.gz in pclos folder on the root of sda4 partition (mounted at /media/disk) and livecd.sqfs at root of sda4:
mkdir /tmp/pclos
sudo mkdir /media/pclos
sudo mount pclinuxos-lxde-2009.4.iso -o loop /tmp/pclos
sudo cp /tmp/pclos/isolinux/vmlinuz /media/pclos
sudo cp /tmp/pclos/isolinux/initrd.gz /media/pclos
sudo co /tmp/pclos/livecd.sqfs /media/

Then I wrote the following lines in/etc/grub.d/40_custom:

menuentry "PCLinux OS" {
set root=(hd0,4)
linux /pclos/vmlinuz livecd=livecd root=/dev/rd/3 vga=788 keyb=us splash=silent fstab=rw,auto changes_dev=/dev/hda4
initrd /pclos/initrd.gz
}

and updated grub:
sudo update-grub

If you are having Legacy grub you have to write following lines in /boot/grub/menu.lst:

Title PCLinux OS
root (hd0,4)
kernel /pclos/vmlinuz livecd=livecd root=/dev/rd/3 vga=788 keyb=us splash=silent fstab=rw,auto changes_dev=/dev/hda4
initrd /pclos/initrd.gz

After reboot I could choose "PCLinux OS" on grub menu and get the Login screen. I logged in as guest and I could see the LXDE Desktop but could not do much before it froze. Then I added vesa at the end of linux boot line in grub and I could use the Live CD.

I went to PCLinuxOS Forum and searched for 82845 and read a couple of posts and got a solution in this post. PCLinux OS loads intel driver which does not work for 82845 chipset, however, it also has the old i810 driver which works.

I clicked on Configure your computer icon in the Application Launch Bar entered the root password (root), clicked on Hardware/Set_up_the_graphical_server/Graphic_card_selection (Intel 810 and later) and changed it to Intel 810, accepted the changes and clicked on Ok to logout. Unfortunately, I got blank screen on logout.

On next attempt I booted without vesa driver and followed the above procedure once again. This time I could get Login screen on logout and after re-login the driver was changed to i810.

If you intend to install PCLnuxOS the blank screen on logout should not matter since the change of driver is already saved by the system.

I can say that PCLnux OS 2009 works for Intel 82845 chipset with i810 driver.

Update:
I have added changes_dev=/dev/hda4 to boot options to have persistent Live system. Now when I change the driver to i810 the new configuration is saved for reboot. The default web browser is Midori. I have installed Firefox 3.5.6 using Synaptic package manager and it is available on reboot.

Sidux with XFCE.

I had tried KDE version of Sidux earlier in May 09 and wrote about it in this post. I decided to try XFCE version this time and downloaded the latest iso. As before I wanted to boot from iso without burning a CD. Now I have grub2, therefore, I opened /etc/grub.d/40_custom to edit and wrote the following lines in it:

menuentry "sidux 32bit from ISO" {

set root=(hd0,4)

linux /sidux/vmlinuz boot=fll quiet vga=791 fromiso=/sidux/sidux.iso persist tz=Asia/Calcutta

initrd /sidux/initrd.img

}

First I copied the iso to 'sidux' directory at the root of sda4 partition (mounted at /media/disk)

sudo cp sidux-2009-03-momos-xfce-i386-200911110039.iso /media/disk/sidux/sidux.iso

Then I mounted the downloaded iso and copied vmlinuz and initrd.img to 'sidux' directory at the root of sda4 partition (mounted at /media/disk):

mkdir /tmp/sidux

sudo mount sidux-2009-03-momos-xfce-i386-200911110039.iso -o loop /tmp/sidux

cd /tmp/sidux/boot

sudo cp vmlinuz* /media/disk/sidux/vmlinuz

sudo cp initrd.img* /media/disk/sidux/initrd.img

Then I updated grub to get the sidux entry in grub menu:

sudo update-grub

Then I restarted and selected 'sidux 32bit from ISO' entry in Grub menu and I could boot into the XFCE Desktop on latest Sidux.

There was a freeze after some time because of the bug in Xorg for Intel 80845 chip-set.
I had faced same problem on Ubuntu Karmic on this chip-set and forced Xorg to use vesa driver by writing xorg.conf. I copied the file to /fll/cow/etc/X11 on sda4:

Section "Monitor"
    Identifier    "Configured Monitor"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Monitor        "Configured Monitor"
    Device        "Configured Video Device"
EndSection

Section "Device"
    Identifier    "Configured Video Device"
    Driver        "vesa"
EndSection

Google Chrome Browser for Linux

Some Linux users were already running Google Chrome Browser from dev channel. Now Google has announced immediate availability of Google Chrome Browser for Linux. You can download it from here. You can download themes and extensions. See my screenshot. I have installed Similar Pages, Feedly, Aviary screenshot utility, Gmail checker and Xmarks extensions and you can see their icons on right side.

Update on Dec 12
When Google announced Chrome Beta it was version 4.0.249.30 and unstable version was also same, however, the development continues and if you upgrade unstable today it is at version 4.0.266.0. If you installed unstable before beta was announced the version changes if you upgrade, however, those who installed beta the version remains at 4.0.249.30, therefore, if you want to stick to beta remove unstable and install beta or don't upgrade unstable and let it stay at version 4.0.249.30.
Update on Dec 17
Today Chrome Beta also got updated to version 4.0.249.40.

Using Google Chromium OS on Desktop.

After Google announced the availability of source of Chromium OS VMWare and USB images appeared on internet. I downloaded USB image but it exceeded the 2 GB size of my pendrive. Then a smaller USB image (less than 1 GB) was made by a developer and I downloaded it today from this site. I extracted the image and copied it to the pendrive through:
sudo dd if=ChromeOS-Cherry.img of=/dev/sdb bs=4M

I could boot from USB to the login screen but it froze after login then I realized that I was using a desktop which has Intel 82845G chipset. Then I modified xorg.conf on the USB stick to use vesa driver.

I could then get to the Chrome browser. I could browse but noticed following two problems:

1. I was already logged in to my Google account but could not use the Blogger even after I logged out of gmail and tried to login to Blogger. The Blogger complains about cookie functionality.
2. When I type I have to wait a few seconds before the text appears on the browser.

Note: On next boot I was already logged into Blogger. You can ignore point 1.

Xmarks on Google Chrome Browser.

I have been running Google Chrome Browser (unstable) on Ubuntu Linux. Today I discovered that I can run Xmarks for Chrome Alpha, version 0.5.11 on it. I clicked on the download link of Xmarks through Chrome Browser and it installed as an extension.


You need to have an Xmarks account to access the download link and the Google Chrome Browser should be from Development Channel.

Xmarks is working perfectly on Google Chrome from dev channel.

How to change default Operating System on Ubuntu 9.10 Karmic Koala

Some people use Ubuntu in dual boot with Windows and they prefer to make Windows as default Operating System. Prior to Ubuntu 9.10 this was achieved by changing the default line in /boot/grub/menu.lst file.

Ubuntu 9.10 Karmic Koala has Grub2 which does not have menu.lst file. The configuration file is /boot/grub/grub.cfg which is not supposed to be edited even by root. The primary configuration file for changing menu display settings is /etc/default/grub. The procedure to change the default OS is as follows:


Count the line number in the Grub menu taking first line as 0.
$ gksudo gedit /etc/default/grub

Change 0 in this line to the desired number:
GRUB_DEFAULT=0

Save and close the file

$ sudo update-grub

After running update-grub the default will change in grub.cfg

Running Ubuntu Karmic on Intel 82845G/GL[Brookdale-G]/GE Chipset

My daughter's Desktop which I use while at Bhubaneswar has this chipset:

$ lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device [8086:2562] (rev 03)

I have installed Ubuntu 9.10 Karmic Koala on this machine and it is having random freezes. I have submitted a bug report but I don't think the bug is going to be resolved very soon. There is another bug resembling mine (my bug may be a duplicate) which has been submitted upstream on freedesktop.org but I don't think that it may be resolved soon.

I decided to change to vesa driver but there was no xorg.conf. I used the following xorg.conf:

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection

There is no freeze using vesa driver.

Update on Jan 1 2010
There is some activity on the bug report. The commit in the Kernel responsible for this bug has been identified and informed upstream. Meanwhile I have found that if I use IceWM instead of gnome there is no freeze with intel driver. If you are comfortable with IceWM you can also use it.

How to boot Ubuntu from Desktop iso.

I have been trying various Linux distributions by copying the contents of Live CD ISO to a spare partition, editing menu.lst file of Grub for suitable entries and booting the operating system. This method saves a CD.

Grub2 is the default boot-loader on Ubuntu 9.10 Karnic for previous distributions you have to install it.

To install Grub2:
$ sudo apt-get install grub-pc
This will install Grub2 but does not replace Grub Legacy and puts an entry in /boot/grub/menu.lst to Chainload and try it. After you find that it is working you need to replace Grub Legacy by Grub2:
$ sudo upgrade-from-grub-legacy

I installed Grub2 recently and discovered that it can directly boot from ISO. I had Ubuntu 9.10 Desktop CD ISO to try. Instead of copying the contents of the ISO I copied the ISO in my-ISO folder on one partition (sda4). Then added following entry in the file /etc/grub.d/40_custom
menuentry "Karmic Live CD (sda4)" {
loopback loop (hd0,4)/my-ISO/ubuntu-9.10-desktop-i386.iso
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/my-ISO/ubuntu-9.10-desktop-i386.iso
initrd (loop)/casper/initrd.lz
}

Then I updated Grub2:
$ sudo update-grub

The update copied the above menu entry from /etc/grub.d/40_custom to /boot/grub/grub.cfg (Please note that you are not supposed to edit grub.cfg directly).

On reboot I selected the new menu entry "Karmic Live CD (sda4)" and could boot from the ISO.

Please note that on Grub2 sda4 is represented by  (hd0,4) and not  (hd0,3) like in Grub Legacy.

How to make manual entry in Grub2 on Ubuntu.

I installed Ubuntu 9.10 Karmic Koala RC today on one partition using Desktop CD. This version of Ubuntu has Grub2 which is under development. The Grub did not detect Ubuntu 9.04 Jaunty Jackalope and I could not boot into it till I studied the problem and resolved it.

As suggested on Ubuntu Wiki I tried the following workaround:

$ sudo apt-get install --reinstall libdebian-installer4
$ sudo os-prober
$ sudo update-grub

The above commands detected the Jaunty installation and updated /boot/grub/grub.cfg file (equivalent of /boot/grub/menu.lst file) but put wrote wrong partition #.

After reading Grub2 documentation on Ubuntu Wiki I made following manual entry in the file /etc/grub.d/40_custom

menuentry "Ubuntu 9.04" {
set root=(hd0,8)
linux /vmlinuz-2.6.28-16-generic root=UUID=5fdb796b-96c0-49f1-80ec-9455e337625c ro xforcevesa quiet splash
initrd /initrd.img-2.6.28-16-generic
}

The partition numbering system has changed on Grub2 and (hd0,8) now means sda8 partition. After writing the above file I had to run:
$ sudo update-grub

to add the entry in grub.cfg file.

How to create Google Chrome theme with your picture.

Since the day I installed Mariah Carry theme on Google Chrome I wanted to create one with my picture. This did not work immediately since the Linux version of Chrome browser could not pack the theme into .crx file. The new version 4.0.222.5 does.

Here is the screenshot of my theme:

This is how I created it:
Create a folder MyTheme and another folder Image inside it. Copy the following text on editor and save it as manifest.json in MyTheme folder.

{
   "name": "name_of_theme",
   "theme": {
      "colors": {
         "bookmark_text": [ 255, 255, 255 ],
         "frame": [ 255, 255, 255 ],
         "ntp_background": [ 45, 42, 41 ],
         "ntp_header": [ 0, 0, 0, 1 ],
         "ntp_link": [ 255, 255, 255 ],
         "ntp_section": [ 68, 68, 68, 0.3 ],
         "ntp_section_link": [ 255, 255, 255 ],
         "ntp_section_text": [ 255, 255, 255 ],
         "ntp_text": [ 255, 255, 255 ],
         "tab_background_text": [ 0, 0, 0 ],
         "tab_text": [ 255, 255, 255 ],
         "toolbar": [ 0, 0, 0 ]
      },
      "images": {
         "theme_frame": "Image/theme_frame.png",
         "theme_ntp_attribution": "Image/theme_ntp_attribution.png",
         "theme_ntp_background": "Image/theme_ntp_background.png",
         "theme_tab_background": "Image/theme_tab_background.png",
         "theme_toolbar": "Image/theme_toolbar.png"
      },
      "properties": {
         "ntp_background_alignment": "bottom",
         "ntp_background_repeat": "no-repeat",
         "ntp_logo_alternate": 1
      },
      "tints": {
         "buttons": [ 1, 1, 1 ]
      }
   },
   "version": "3"
}

Replace "name_of_theme" with the name you want to give to the theme.

Now you require following images in the Image folder:

theme_frame.png

theme_ntp_attribution.png

theme_ntp_background.png (Put your photograph as this image)

theme_tab_background.png









theme_toolbar.png

You can download the images from this page.

Next step is to pack the theme. Type the following in the address bar of the chrome browser:
chrome://extensions/
Click on Pack_extension under Tools.
Click on Browse for Extension_root_directory
Chose MyTheme Folder
Click on Ok.
This will create two files MyTheme.crx and MyTheme.pem.

Now you have to open the .crx file using Chrome browser. You can do this by typing the following in the address bar:
file:///path_to_MyTheme.crx

Save the file and the theme is installed.

Google Chrome Browser on Ubuntu with nice themes.

As per Google the Chrome Browser for Linux is under development. For Ubuntu user it is a fairly developed Browser with Flash working and even themes could be installed from Google Chrome Themes Gallery. Look at the Mariah Carry Theme on my Browser running on Ubuntu 9.04 Jaunty Jackalope:

I have installed Daily Build of Chromium Browser available on following PPA:
http://ppa.launchpad.net/chromium-daily/ppa/ubuntu
the GPG key can be added from the following command:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 4E5E17B5


For some people what I have installed from PPA is Chromium and not Google Chrome, although, both are same browser. If you want to install with the name Chrome here is the link to Chrome .deb package. 

Tux Paint Open Source Drawing Software for Children.

I installed Tux Paint on Ubuntu for my grand daughter but while teaching her how to use it I have fallen in love with it since I can't paint. It has an option called Stamps which can be used to insert images on the canvas like the following images of the Sun, Seagull and 3 types of houses on the following painting:

Talking about my lousy painting I painted this one using GIMP.

Install new Opera 10 on Ubuntu

Opera 10 was released on 1st September and I tried to upgrade since the Opera deb repository was already available on my software sources file. Then I noticed that I had not added the Opera GPG Key. I added the key:

$ wget -O - http://deb.opera.com/archive.key | sudo apt-key add -

and I could upgrade to the new version.

How to talk using Pidgin 2.6.1 on Ubuntu Jaunty.

Pidgin 2.6.0 was released on Aug 19 2009 and brought good news to Linux users that it comes with Voice and Video support.

This is how I installed on Ubuntu 9.04 Jaunty Jackalope.

Removed existing Pidgin:

sudo aptitude purge pidgin pidgin-data libpurple0 libpurple-bin

Add the following repositories to Software sources:

deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu jaunty main

Add signing keys:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A1F196A8

Update and install:

sudo aptitude update
sudo aptitude install pidgin

For audio/video calls:

Double click the buddy and
Click on Conversation/Media in the new window.

If the buddy does not have audio/video facility the options will be greyed out.

Google Applications for small business owners.

My son-in-law launched a company this month and was looking for low cost email, Document Sharing and website solution and I discovered standard edition of Google Applications which is giving more than he asked for and only at the cost of a domain registration.

Printing Mailing Labels using gLabels

When there are weddings you need to send large number of invitations. You need to build postal address database and then print mailing labels. I had prepared address database for my daughter's marriage in 2001 but lost the file due to loss of hard disk on my old desktop from which data could not be recovered.

Another marriage is planned in Nov 2009 and since advance period of rail reservations is 3 months formal letters of invitations are required to be sent by first week of Aug 09.

This time I have prepared the Database in Spreadsheet on Google Docs so that it does not get lost. I have shared the document with others so that addresses could be fed into it quickly.

I bought Mailing Labels from a Stationery shop and the page format is 210x306 mm which looks non-standard. The product is from Oddy and perhaps obsolete (meant for Dot-matrix Printers).

I tried to create the Labels in Open Office but it has selection for Brand of paper and Oddy was missing from the list and no Brand was close enough.

Then I searched for "Printing Labels on Ubuntu" and discovered gLabels and installed it.

gLabel also had many templates but I decided to create one for Oddy for the paper size I had. There is a Template Designer accessible through File Menu. I selected custom size of paper and entered the measured dimensions. Then I entered the dimensions of the Label, no of Labels on the paper (16), horizontal and vertical pitch etc. carefully and saved the template but it was not satisfactory. Then I opened the XML file of the template from ~/.glabels as text file and edited and saved it.

gLabel does not accept spreadsheet data, therefore, I saved it in CSV format and used it through "Merge Properties". For entering text on the label, I created the text objects and inserted the merge fields into them.

I could print the Mailing Labels perfectly on the non-standard stationery. Before printing I went into the printer set up and selected Custom paper size.

Opera Unite provides webserver, chat room, file sharing right from your PC.

Opera Unite was launched on 16th June 09 and I decided to give it a try on first day. When I clicked on the download link on Opera Unite page it was nothing but version 10.00 Beta of Opera browser. I downloaded the .deb package and installed on Ubuntu Jaunty Jaackalope.

When I opened the browser there was Unite icon on side panel. I could use myopera userid and password to setup the system on my PC. Immediately I could start the chatroom on my PC and send the link to my friends and chat with them.

I had developed some content regarding my experience on steam Turbines using Tiddlywiki in 2007. I could immediately setup website on my PC using that content.

For sharing photos and files I don't need to upload them anywhere. My friends could download directly from my PC.

All these things have become so easy for common user.

Uzbl the new usable browser on Ubuntu 9.04 Jaunty Jackalope

Uzbl is a new Webkit based browser with minimal graphical interphase. For opening a URL you have to type 'o URL' and it opens. See the screenshot below:

For adding a bookmark you have to type 'B'. For loading a bookmark you have to type 'u' and for loading a URL from history you have to type 'U'.

Actually o, B, u, U etc are keybindings defined in the config file and B, u and U also call the required scripts.

Tabbed browsing is not available but you can open any number of windows for different URLs.

This browser is being developed on Archlinux and easily installable from AUR. The bookmarks and history use the utility dmenu which has been patched for displaying the URLs vertically and available as dmenu-vertical in AUR.

After installation you can start the browser with 'uzbl' command but you get a blank browser window which does nothing since there is no default configuration. You need to create 'uzbl' folder in ~/.config and copy the following two files in it:

cp /usr/share/uzbl/examples/configs/sampleconfig ~/.config/uzbl/config

cp /usr/share/uzbl/examples/configs/cookies ~/.config/uzbl/

For bookmarks you need to create 'uzbl' folder in ~/.local/share and copy the file:

cp /usr/share/uzbl/examples/data/bookmarks ~/.local/share/uzbl/

and create an empty session file:

cd ~/.local/share/uzbl

touch session

You can also create a launcher uzbl.desktop:

[Desktop Entry]

Encoding=UTF-8

Name=Uzbl

GenericName=uzbl

Exec=/usr/bin/uzbl %u

Terminal=false

Type=Application

Categories=Application;Network;

Icon=applications-internet

All the above settings are required even on Archlinux on which it is being developed since the developer is trying to just give a browser with all other things managed from scripts outside the browser, although, thy are giving 'example scripts' and the settings given above configure these example scripts to work in conjunction with the browser.

Now let us come to installation of uzbl on Ubuntu 9.04 Jaunty Jackalope.

For installing the recent version of Webkit Library add the following sources to /etc/apt/sources.list

deb http://ppa.launchpad.net/webkit-team/ppa/ubuntu intrepid main

deb-src http://ppa.launchpad.net/webkit-team/ppa/ubuntu intrepid main

to import keys

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0x991e6cf92d9a3c5b

and to install

sudo apt-get update

sudo apt-get install git git-core libwebkit-dev

to compile and install uzbl

git clone git://github.com/Dieterbe/uzbl.git

cd uzbl

make

sudo make install

After installation on Ubuntu you need to create uzbl directory in ~/.config and ~/.local/share and copy/create the files as stated above.

In addition, Ubuntu does not have $XDG_DATA_HOME set to ~/.local/share by default and dmenu-vertical is not available in Debian/Ubuntu repositories. These things are required by the example scripts.

There are various ways to set the environment variable $XDG_DATA_HOME but I simply decided to put the following line in the load_url_from_bookmarks and insert_bookmark scripts for the time being.

XDG_DATA_HOME=~/.local/share

I have downloaded dmenu-4.0 sources from:

wget http://code.suckless.org/dl/tools/dmenu-4.0.tar.gz

and the required patch from:

wget http://evaryont.me/dmenu-vertical-history.patch

and compiled dmenu-vertical:

tar -xvzf dmenu-4.0.tar.gz

cd dmenu-4.0

patch -p1 < ~/path-to/dmenu-vertical-history.patch

make

sudo checkinstall

I used checkinstall to make .deb package of dmenu-vetical.

VOIP to Gtalk, YM, MSN using Gizmo.

I have setup Gizmo on Ubuntu and called couple of friends (Windows users) on their Gtalk and Yahoo Messenger and had voice chat today and surprised them.

Gizmo has not updated its Linux version since Nov 2007 and there is lot of criticism by Linux users on its forum. I had to use OSS to make the audio work.

Once setup and audio checked through free sip call to Echo Test I could easily import the Gtalk and YM buddies and could have text chat with online buddies but voice chat did not work. This was happening because they were setup as user_id@xmpp.chat.gizmoproject.com (Gtalk) user_id@yahoo.chat.gizmoproject.com

Then I added one contact as user_id@gmail.com and called him and had successful voice chat.

Booting sidux from iso with persistent

I wanted to try sidux since long time. I downloaded the KDE lite version and searched on Google for 'sidux boot from iso' and got the page Booting with "fromiso" of sidux manual.

I created sidux folder at the root of an ext3 partition and copied the iso, vmlinuz and initd.img as per instructions and created following entry in /boot/grub/menu.lst

title sidux 32bit from ISO
kernel (hd0,X)/sidux/vmlinuz boot=fll quiet vga=791 fromiso=/sidux/sidux.iso persist
initrd (hd0,X)/sidux/initrd.img

After booting into sidux KDE 3.5.10 desktop I configured static IP through Ceni. Then I added noxorgconf and nonetwork boot parameters so that sidux does not create xorg.conf and reconfigures the network on reboot.

Since I don't like browsing with Konqueror I installed Iceweasel.

After reboot I found my static IP configuration intact and Iceweasel available.

The persist boot parameter creates folder fll at the root of same partition and uses the remaining space on the partition.
