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.

Installation of Archlinux from archiso-live-2009-05-24.iso

I had earlier installed Archlinux after downloading Core installer and following Beginners Guide on ArchWiki.

After reading about Archlinux Live CD archiso-live developed by godane on latest issue of Distrowatch Weekly I decided to give it a try and also use the installer.

I was very much impressed with the Live CD with Xfce as default and choice of LXDE, e17, gnome, openbox-session, Fluxbox by pressing F1 key at Slim Login Manager. The normal user login is arch/arch and root login is root/ArchLinux

The choice of applications is also good:
Blender, Comix, GIMP, GPICViewer, Rawstudio, mtPaint in Graphics category
Arista, Asunder, Audacious, Audacity, Avidemux, Elisa, Hydrogen, VLC in Multimedia category
Abiword, Gnumeric, HomeBank in Office category.

I decided to give the installer a try. Initially, the installer produced some errors after partitioning stage while copying files. I googled for the errors and decided to logout and login as root.

The installer worked this time and copied all the files successfully and failed at Bootloader stage (which I did not want to use anyway).

I found the installation in order except /etc/fstab (which was meant for Live CD) and some tweaks needed in /etc/rc.conf file DAEMONS line. I used the Beginners Guide to build /etc/fstab and also corrected the DAEMONS line.

I made an entry in present /boot/grub/menu.lst as suggested in Beginners Guide and I could boot into the installed Archlinux.

I found that the installer did not delete the Live CD user "arch", therefore, I logged in as arch password arch and everything is working fine.

I updated the system through pacman and found upgrades to clamav, docbook, pidgin, xchm and openvpn which I applied.

Ulx 9.04 Ubuntu based LXDE Live CD with all applications.

Today I am putting new iso of Ulx 9.04 on Linuxtracker.org which has Ubuntu 9.04 minus Gnome (replaced by LXDE), gnome-panel (replaced by lxpanel), Nautilus (replaced by PCManFM), gnome-terminal (replaced by LXTermina), gedit (replaced by Leafpad) but all other applications on LXDE Desktop. I have removed things which refer to Ubuntu like usplash (replaced by LXDE splashy), Ubuntu Docs, Ubuntu themes and wallpapers, Ubufox etc, GDM Ubuntu Themes. COMPIZ is also removed (replaced by Openbox).

It has gnome-games, Brasero, Movie Player (xine based), Rhythmbox, Pulse-audio, F-spot, GIMP, GPICViewer, XSane, Network Manager, Add/Remove, Computer Janitor, Language Support, Network Tools, Synaptic, System Monitor, Update Manager, Ekiga, Evolution, Firefox, Pidgin, Transmission, Open Office (minus Dictionery, language support). In short everything Ubuntu 9.04 has.

Some people may say it is as heavy as Ubuntu itself, may be. I have not tried to make it lighter by removing applications but I am sure the distrolet is lighter than Xubuntu.

In addition, I have written a small utility "mykeyboard" which helps in adding a Keyboard Layout to the default US Layout and added fbxkb to toggle.

Please download from torrent, seed it for some time, try it and post your comments here.

Ulx -- Ubuntu 9.04 distrolet with LXDE.

Today I made Ubuntu 9.04 LXDE Live CD and uploaded the iso on LinuxTracker. This is an experimental effort to get user feedback. At present it has Firefox 3.0.10 OpenOffice 3.0.1 gnome-games Leafpad only.

I am going to add multimedia applications and upload another iso image shortly.

Users are requested to write their feedback about Ulx 9.04 under comments on this blog post.

xserver crash on restart taught me optimised use of memory.

I have a machine which originally arrived with 128 MB RAM and Linux Distributions with 2.4 series kernels (Mandrakelinux 9.1) worked well with this memory. Even Ubuntu 5.04 with 2.6 series kernel worked vey well.

Subsequently I added 256 MB RAM to the machine making it 384 MB to use Ubuntu 6.06 Dapper Drake properly.

I soon learnt to use lightweight Window Managers to have good speed with later versions of Ubuntu and also tried Debian and Arch Linux to further optimise thye memory usage.

The video setting in the BIOS was on "Auto" and 72 MB RAM was getting allocated towards the video leaving 312 MB for the OS.

Although Ubuntu says that its Live CD works with 256 MB RAM it is very slow and even 312 MB is less for effective use.

Recently I downloaded Ubuntu 9.04 Beta Live CD and in order to use it effectively changed the video setting in the BIOS to minimum (8 MB). The memory available for the Live CD was 360 MB (instead of 312 MB) and it worked very well.

Subsequently I forgot to restore the BIOS setting and continued using Linuxes installed on the hard disk (Ubuntu Hardy, Archlinux and antiX). They were working very well till I decided to change the Window Manager on Ubuntu Hardy and logged out of GDM to change session. To my surprise, the xserver crashed. I checked restart of xserver on Archlinux and antiX and it crashed on those distributions as well.

I googled for "xserver crash on restart" and read many bug reports and tried some remedies. Ultimetly I discovered the BIOS video setting and changed it to "Auto" once again.

Then I remembered that I had tested "logout" on Ubuntu 9.04 Beta Live CD and xserver did not crash.

I changed the BIOS video seiing to 16 MB and found that Archlinux (with xserver 1.5) did not crash on restart but Ubuntu Hardy Heron (which has xserver 1.4) required 32 MB setting in the BIOS.

Today I upgraded to xserver 1.6.0 on Archlinux and it is not crashing on restart with minimum (8 MB) video setting in the BIOS (like Ubuntu 9.04 Beta). With this setting the available memory for the OS has jumped from 312 MB to 367 MB.

Debian Live LXDE persistent mode

I was very happy that Debian Lenny had Live LXDE Desktop CD. I had tried it briefly earlier. Today I decided to use the persistent mode i.e. changes saved in live-rw file and used on reboot.

As always I copied the contents of Debian Live LXDE iso to a 1 GB partition and edited /boot/grub/menu.lst to make following entries:

title Debian Live LXDE
root (hd0,7)
kernel /live/vmlinuz1 boot=live union=aufs ip=frommedia swapon timezone=Asia/Kolkata persistent noprompt
initrd /live/initrd1.img

Explanation of boot parameters:
boot=live union=aufs This is copied from live.cfg file in isolinux directory
ip=frommedia This tells the system to read configuration from /etc/network/interfaces saved from earlier boots.
persistent This tells the system to look for live-rw home-rw partitions or files on the hard disk
noprompt This tells the system not to wait for removing Live CD on shutdown/restart

For persistent media I created live-rw on one partition (mounted at /media/disk) as follows:

$ dd if=/dev/null of=live-rw bs=512M seek=1
$ /sbin/mkfs.ext2 -F live-rw
$ sudo mv live-rw /media/disk

Just to check that persistent includes the installed .debs I installed ttf-indic-fonts:

$ sudo apt-get install ttf-devanagari-fonts

and the fonts are available on reboot.

All my personal settings are available, although, I did not create separate home-rw because live-rw includes changes to /home/user

Couple of steps on Zenwalk 6.0

Finally I have made Zenwalk 6.0 usable to my liking.

Setting static IP through Ethernet
Remove Wicd from Startup services:

Start Control_Panel (zenpanel}
Click on Startup_Services
Uncheck Wicd
Click OK.
Click on Session_and_Startup in XFCE Settings Manager.
Click on Application_Autostart
Uncheck on Wicd.
Close

Reboot.

Set up through netconfig (Just enter the required information):

$ su
Password:
# netconfig

Restart network (if you know how) or reboot.

Gmail Display problem
This is how Slackware site looked on Iceweasel on Zenwalk 6.0.

Similar problem was happening in Gmail. After reading on Zenwalk Forum I added the following lines in Device section of xorg.conf and it worked.

Option "AccelMethod" "XAA"
Option "XaaNoOffscreenPixmaps" "on"

Zenwalk 6.0

I decided to try the new Zenwalk 6.0. As usual I copied the contents of the iso to a partition and found nice article on Zenwalk Wiki. Accordingly I edited the existing /boot/grub/menu.lst:

title Zenwalk 6.0 install
root (hd0,X)
kernel /kernels/ata/bzImage
initrd /isolinux/initrd.img

As per instructions I selected "Exit setup" and got root shell where I mounted the extracted iso:

cd /
mkdir zeniso
mount /dev/sda(X+1) /zeniso
setup

and started the installation. When it asked for source selection I selected "Install from a pre-mounted directory" and when asked for the directory where the installation files are:

/zeniso

and continued the install. I did not install the bootloader and edited the /boot/grub/menu.lst once again to make an entry for Zenwalk:

title Zenwalk 6.0 (on /dev/hda6)
root (hd0,5)
kernel /boot/vmlinuz-2.6.28.7 root=/dev/sda6 ro
initrd /boot/initrd.splash

Next step was to connect to internet on newly installed Zenwalk 6.0 but I had to struggle because Wicd 1.5.9 does not detect the wired ethernet connections properly. I had to setup as follows:

$ su
Password:
# ifconfig eth0 down
# ifconfig eth1 192.168.1.3 netmask 255.255.255.0 up
# route add default gw 192.168.1.1
# exit

I am yet to find out a way to save the above configuration.

After choosing the timezone the clock did not indicate my time. I discovered that Zenwalk was assuming that the hardware clock was set to localtime (which is actually UTC). After struggling a little I found the file /etc/hardwareclock and changed the word 'localtime' to 'UTC' and it worked.

I also installed ttf-indic fonts and flash-plugin using Netpkg.

Zenwalk 6.0 has XFCE 4.6 which I had briefly used on Arch Linux the day it was released and now trying it on Zenwalk.

I am going to love antiX

I tested two Live CDs today. The first one was Debian LXDE Live downloaded from cdimage.debian.org/cdimage/release/current-live/i386/iso-cd/ It booted into nice LXDE Desktop with GIMP and OO apart from usual LXDE software. But there was no Network Manager and since my present router is not connected to NIC I had to manually configure the USB router by editing /etc/network/interfaces and /etc/resolv.conf But it is a good Live CD for machines having as low as 64 MB RAM. The Live CD does not have an installer and you can only have frugal type of install on hard disk.

The next Live CD was antiX-M8 'Intifada!' with IceWM as default Window Manager but believe me no distribution has such lovely IceWM fully configured:


I had Debian Lenny installed on one partition since Sep 08 which was not updated and the updates were huge. I decided to replace Debian Lenny with antiX since it is based on Debian Lenny with 2.6.27 Kernel.

Flash MPEG everything just works out of the box.

I am going to love antiX.

Enjoying the latest software on Arch Linux

I had installed Arch Linux on one of the partition in Sep 2008 but did not use it much since I was forced to use vesa driver because ati driver had a bug and it did not work on secondary monitor. Although Ubuntu 8.04 Hardy Heron had the same bug I could update the driver through Debian Sid in June 2008 after the bug was removed.

Arch Linux is a rolling distribution and latest packages are periodically transferred from testing to main repositories and you need to just upgrade the packages through pacman.

Xorg 7.4 was moved to extra repository on 30th Nov 2008 and I was eager to use it to test the driver. I upgraded Xorg and on reboot found that although the ati driver worked for the secondary monitor the touchpad did not work. After exploring I found that this version of Xorg had input hotplugging enabled by defaut. After reading on this page I added the following packages:
xf86-input-evdev xf86-input-vmmouse xf86-input-synaptics

and it worked.

Then I did the system wide upgrade and now I have:
Linux Kernel 2.6.28
Xorg 7.4 (xserver 1.5.3) working without xorg.conf
Gnome 2.24
Open Office 3.0.1
GIMP 2.6.4
All latest packages on LXDE

Upgrading to Open Office 3.0 on Ubuntu

Open Office 3.0 has been released but it is not available on Ubuntu 8.04 or 8.10. Fortunately it is available on Launchpad repository. Add the following repository to your software sources:
deb http://ppa.launchpad.net/openoffice-pkgs/ppa/ubuntu hardy main

Replace hardy with intrepid if you are running Ubuntu 8.10.

Get the PGP Key from the following URL:
http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x60D11217247D1CFF

Save the PGP Key to a text file and add it through Authentication tab and click Import Key File… on Software sources.

If you already have Open Office 2.4 you can do:
$ sudo apt-get update
$ sudo apt-get upgrade

otherwise you can install the entire office suite through:
$ sudo apt-get install openoffice.org

Making custom Ubuntu Live CD using Remastersys

I use LXDE desktop on Ubuntu and wanted to make a Live CD from the hard disk installation. It was so easy using Remastersys.

I added Remastersys repositories to the sources:
deb http://www.remastersys.klikit-linux.com/repository remastersys/

Then installed Remastersys:
$ sudo apt-get update
$ sudo apt-get install remastersys

There was a menu entry "Remastersys backup" which I clicked, selected "Dist" and clicked on ok.

After some time "customdist.iso" was created in /home/remastersys/remastersys

I burned the iso to a CD and it works.

My custom distribution is Ubuntu 8.04 Hardy Heron on LXDE with all updates, gnome-games, Brasero, Mplayer, GPIC Viewer, xpdf, Synaptic, Firefox 3.0.5 (with Adobe Flash Player), Pidgin, Transmission, OpenOffice.org 3.0.1, PCManFM, Leafpad, Xarchiver. The size of the iso is 686.5 MB

My review of KDE 4.2

I am not a fan of KDE or Gnome since both have become too heavy for the kind of machines I use but I try when something new comes up. I had tried KDE 4.0 last year and wrote about the Desktop Widgets.

Since KDE 4.2 is having many new features i decided to install it. I have Ubuntu 8.04 on this machine but KDE 4.2 is not available for this version. I decided to install Kubuntu 8.10 for a change. After installation I applied all the updates. Then added the following repository:
deb http://ppa.launchpad.net/kubuntu-experimental/ubuntu intrepid main

and the package signing key through the command:
gpg --keyserver keyserver.ubuntu.com --recv-keys 493B3065 && gpg --export -a 493B3065 | sudo apt-key add -

Then updated through Adept Updater tool in the system tray.

After reboot it was KDE 4.2.

Some people don't like the application launcher of KDE 4 for them the old launcher has been added as a widget called traditional menu based launcher. There are many widgets and I have added Analog clock, CPU Temperature, weather, Twitter and Calculator and you can see them on the screenshot below:


In addition the KDE Window Manager has Desktop effects like COMPIZ and you can see the cube below:

My review of KNOPPIX 6.0

I am long time user of various Linux distributions and also love Live CD distributions. I had never tried KNOPPIX before. I downloaded KNOPPIX 6.0 yesterday and burnt a CD. I never burn a CD to try new distributions but I had to for KNOPPIX (that story for some other day).

KNOPPIX 6.0 comes with LXDE (which I love) as default but it also uses COMPIZ as default (this I did not know till the desktop appeared).

My review: I have fallen in love with default COMPIZ settings on KNOPPIX 6.0. See the screen shots below:

Cube with glxgears rotating inside



and this is what happens when you close an application;

Live CD has following applications:
GnomeMplayer with multimedia codecs (I tried wma and mp3)
GIMP ImageViewer xpdf
CCSM LXRandR
gconf-editor NM_Applet(0.70) PCManFM Synaptic Wavelan Xsceernsaver
elinks Icedove Iceweasel Pidgin Java6_Web_start
Open_Office_3.0.1
Leafpad LXTerminal Orca File_search_utility XArchiver

on LXDE/COMPIZ
with Linux 2.6.28 and Xorg 7.3 (xserver 1.4.2)

TinyCoreLinux

TinyCoreLinux the wonderful 10 MB Linux Distribution on which you can add applications and run.

You can see icons of aterm, panel, applications_browser, emelfm, Leafpad, Firefox and GIMP on Wbar.

I have downloaded the wallpaper and added Tinycore logo using GIMP.



Here is the wallpaper image without Wbar for you.


and here is the original image:

Rediscovering SLAX .

I had checked SLAX in Feb 2008. Today I decided to download version 6.0.7 and try it. As before I mounted the iso and copied it to a spare partition and edited grub to add the following entry:
title SLAX 6.0.7
root (hd0,X)
kernel /boot/vmlinuz root=/dev/ram ramdisk_size=6666 rw changes=/dev/hdd(X+1) autoexec=xconf;telinit~4
initrd /boot/initrd.gz
boot

As before I opened KDE Control Center, clicked on Regional and accessibilty, Keyboard Layouts and removed all Keyboards except US English and added India. I also added ttf-indic fonts.through System Administration, Font Installer.

Then I searched for Firefox 3 Slax module and downloaded it with following dependencies:
SQlite 3.6.6.2
libgconf2-4
libgnomevfs2.0
liborbit2
Gecko-Seamonkey-Proof-Of-Concept 1.0.0

As before I copied the modules to /mnt/hddX/slax/modules and activated them through System/Slax Module manager.
