Using Wayland Display Server on Ubuntu 17.10 and Ubuntu 16.04 LTS

After reading on omgubuntu that Wayland will be the default Display Server on Ubuntu 17.10 (under development) I downloaded the Daily ISO of Ubuntu 17.10 and installed on one spare partition.

For those who are not aware Ubuntu has dropped Unity and Gnome will be the Desktop for Ubuntu 17.10. Gnome already has Wayland session.

At login I selected Ubuntu Wayland Session and could login and use the Gnome Desktop without any difficulty.

After testing I connected my Android Phone through Bluetooth and tried to play the Music from JioMusic on Laptop speakers and it worked. But I could not transfer the photographs from the phone.

After searching I found a Bug and workaround. To use the workaround permanently I used the following commands:
sudo systemctl --global enable obex

gnome-session-properties
Add a new entry:
Name: gnome-user-share-obexpush
Command: /usr/lib/gnome-user-share/gnome-user-share-obexpush
Save

Enable the new entry through the command or relogin.


I could transfer the photos to the laptop.


Now I decided to use Wayland on my present OS i.e. Ubuntu 16.04 LTS.
I had already added Gnome Desktop earlier since it is going to be the default Desktop in upcoming versions. I installed gnome-session-wayland logged out and tried to login after selecting Gnome Wayland session but could not login.


Then I discovered that there is a Bug for login through LightDM greeter.
I  switched to GDM3 through:
sudo dpkg-reconfigure gdm3

Now I could use Wayland on Ubuntu 16.04 LTS as well by selecting Gnome Wayland session.

I forgot password of Ubuntu 16.04 Desktop.

I forgot Ubuntu 16.04 login on my Lenovo Laptop and wanted to create new password.

In Grub menu I clicked on Advance Options and selected Recovery Mode to boot.

After boot in Recovery Mode I selected Root and pressed enter to get Root Terminal.

Ubuntu Recovery Mode mounts / File System in Read Only mode, therefore I remounted it.
# mount -o remount /

and I could set the password by typing
# passwd username

and after
# reboot

I could login with the new password.

Next Day I remembered the forgotten password and restored it once again.

My Laptop is on IPv6 and fallback IPv4 through Jio Hotspot.

What is IPv6?
IPv6 is short for "Internet Protocol Version 6". IPv6 is the Internet's next-generation protocol, designed to replace the current Internet Protocol, IP Version 4.
In order to communicate over the Internet, computers and other devices must have sender and receiver addresses. These numeric addresses are known as Internet Protocol addresses. As the Internet and the number of people using it grows exponentially, so does the need for IP addresses.
IPv6 allows more users and devices to communicate on the Internet by using bigger numbers to create IP addresses. Under IPv4, every IP address is 32 bits long, which allows 4.3 billion unique addresses. An example IPv4 address is:

172.16.254.1

In comparison, IPv6 addresses are 128 bits, which allow for 
approximately three hundred and forty trillion, trillion unique IP 
addresses. An example IPv6 address is:

2001:db8:ffff:1:201:02ff:fe03:0405

One day Internet Speed was slow on my Mobile and I changed

to APN Protocol IPv4/IPv6 and it improved

But I was getting only IPv4 address on Laptop connected to the

Hotspot. Then I changed Hotspot settings also to IPv4/IPv6.

Now I am having both IPv4 and IPv6 addresses on my Laptop.

Bodhi Linux 4.2.0 a light distro based on Ubuntu 16.04

Bodhi Linux 4.2.0 was announced on 31st May 2017 and I  decided to try it compare how light it is compared to Ubuntu 16.04.

I was impressed with the memory used on booting to the Desktop:
~$ free -m
              total        used        free      shared  buff/cache   available
Mem:           1706         160        1185           9         360        1378
Swap:          1023           0        1023

I was also impressed with the memory used with 3 Tabs open on Midori Browser:

~$ free -m

              total        used        free      shared  buff/cache   available

Mem:           1706         565         704          19         436         960

Swap:          1023           0        1023

Unfortunately Google does not support Midori Browser and the New Post Page refused to open on Blogger.

I installed Chromium Browser from Bodhi AppCenter and using it now with 4 Tabs open:

$ free -m

              total        used        free      shared  buff/cache   available

Mem:           1706        1008         135          23         561         505

Swap:          1023           0        1023

Although the Blogger New Post page refused to open gmail opens but complains of unsupported Browser but mail  functions work.

I am happy  with Bodhi  Linux 4.2.0 performance.

I could also edit this page on Midori Browser. It works. 

Correct way to watch JioTV and other apps on Jio Network and enjoy free calls.

Jio has been providing 1 GB daily Data and free incoming and outgoing calls to any Network since Sep 2016 to those who had 4G Phones in the name of  Welcome Offer, Happy New Year Offer and  Summer Surprise Offer but I find that many people are not enjoying the offers fully.

Most people have Broadband Connection at home and their phone gets connected to Home Wifi Network when they reach home. Now if they try JioTV it does not work because it necessarily requires Jio Mobile Network. For JioTV to work properly at home you need to disconnect from Home Wifi Network and connect only to Jio Mobile Network.

For receiving and making free calls, if your phone is Volte it works even when you are on Home Wifi Network.

If your phone is only 4G (without Volte) you need to disconnect from Home Wifi Network and connect only to Jio Mobile Network and keep Jio4GVoice app working to receive and make free calls.

Reverification of Mobile nos through Aadhar and locking of Biometrics

I received sms from Idea that I need to get the re-verification through Aadhar Biometric since it is mandatory now. Without giving a second thought I went to neighborhood Idea Customer Care Center and told my Mobile number. They sent an OTP on the number and after getting the OTP began the process of verification through Aadhar Biometric. My finger Biometric did not work after many attempts.

After coming home I recollected that I had locked my Aadhar Biometric through Aadhar Services website.

I went back to the site and unlocked the Biometric but it allowed me only 20 minutes after which it would be automatically locked again. Then I disabled the Biometric lock.

After going back to Idea Customer Care Center I could re-verify my Mobile no through Aadhar Biometric.

I have enabled the Biometric lock once again and I hope to remember to disable it again if I need verification anytime in future.

Ubuntu Desktop Team wants your feedback.

The Ubuntu Desktop team is tasked with transitioning Ubuntu desktop over from Unity to GNOME — and they need your feedback to help them do it.

The above poll is appearing on OMGUbuntu

I am using Ubuntu for more than 12 years now. From next year Ubuntu 18.04LTS Ubuntu is going to shift from Unity Desktop to GNOME.

Presently I am using Ubuntu 16.04LTS and generally use GNOME fall-back session. I was also keen to try GNOME Desktop on Ubuntu 16.04.

I clicked on the Install GNOME shell link on OMGUbuntu page, installed it and logged out of fall-back to GNOME session.

GNOME extensions are installed through Browser but Firefox requires you to enable GNOME integration. For this I followed following page on OMGUbuntu

After integration I went to GNOME Extensions page and installed the following extensions:

• Dash to Dock
• Impatience
• No Top Left Hot Corner
• Alternate Tab

• Applications Menu
• Better Volume Indicator
• TopIcons Plus

 

and participated in the survey. I also installed Caffeine and Open Weather extensions.

 

I am now using GNOME Desktop on Ubuntu 16.04.

Transferring Contacts from Nokia X2-00 to Android Phone

I am helping husband of my sister-in-law to shift from ordinary Nokia phone to Volte smartphone. For buying his preference was Samsung Volte so we bought Samsung Galaxy On7 Pro online. After delivery of the phone and charging the Battery we went to Reliance Digital Express to buy Jio sim. The main problem was to transfer Contacts from Nokia Phone to the new Android Phone.

I got the Model No of Nokia Phone by dialling *#0000# it was Nokia X2-00
Then I searched suitable Nokia Suite for the Model and downloaded Nokia Suite 3.8.54 on Laptop.
I connected the phone to the Laptop through USB Cable and tried to Synchronize Contacts on Nokia Suite but it failed. Then I switched on Bluetooth on the phone and connected through Bluetooth. I could synchronize the Contacts.

I exported all the Contacts to a Folder NokiaX2-00
I opened the Windows Terminal and typed the following command after navigating to NokiaX2-00 folder.
COPY *.VCF combined.VCF

I exported the file combined.VCF to Google Contacts and synchronized on Android Phone.

Fix for JioTV not working.

I am presently at Bhopal and my Jio phone is on roaming. Today JioTV did not work in spite of internet speed of 15 Mbps or more. After googling I got following solution which worked for me.
1. Uninstall and reinstall JioTV app.
2. Go to Settings/Mobile Network/Access Point Names/APN which is Jionet. Edit the following setting.
APN Protocol IPv4
APN roaming protocol IPv4
Bearer LTE
JioTV started working.

Yesterday one old man brought his smart phone Panasonic Eluga Switch. He had Jio sim in slot 1 and Airtel sim in slot 2. After Android System update the Ringtone did not work for sim2.
After struggling for two hours I found interrupts setting in Sound in which calls was disabled. After enabling it the ringtone worked for sim2.

Improvement in Internet Speed on Jio Network at Delhi.

Since I have come back to Delhi on 8th Feb 2017 I  find that Internet Speed has greatly improved at my home. Earlier I could watch videos only during morning upto 7 AM now I could watch them anytime.

One more  good news is the Android version on my Cooldpad Mega 2.5D is upgraded and now the 4GVoLTE phone calls are working fine from Dialer.

The present Data Limit on Jio is  1 GB/day and due to this competition Airtel Broadband has revised the Monthly Data Limit to 30 GB and speed to 16 Mbps at the minimum tariff of Rs 899/month with unlimited free local and STD calls.

Jio has announced that it will charge Rs 303/month for 1 GB/day Data under Prime Subscription from 1st Apr 2017. This is almost 1/3 of what I am paying to Airtel.

Let me see whether Airtel Broadband further reduces Tariff.

Problems with voice calls on Jio 4GVoLTE.

I was using Coolpad Mega 2.5D since Oct 2016 on Jio 4G network. Voice calls used to work through Jio4GVoice app. Since the update dated 27th Jan 2017 of Jio4GVoice app is asking me to use the phone dialer since this is VoLTE phone but it is very difficult to use the phone dialer for making voice calls. It does not connect unless I disable and re-enable the enhanced 4G LTE mode in network settings.

Cashless Transactions since Nov 8 2016

I was already using paytm since Feb 2015 for Mobile Recharge then in Oct 2015 I did online shopping on it. In Jan 2016 I paid first electricity bill on it. During the year 2016 I used freecharge or paytm for payment of electricity bill. Then Mother Dairy introduced paytm on milk booths and I was first customer using paytm on nearby Mother Dairy Booth. I had also used Debit and Credit cards for online transactions and shopping for many years.
In short I was fully ready for cashless transactions when old currency was banned on Nov 8 2016. I happily used paytm or credit card wherever acceptable.
I grabbed UPI ID userid@icici when it was offered by ICICI Bank and ready for UPI Transactions.
I downloaded BHIM android app and got mobileno@upi ID also.
This worked very well for ICICI Bank.
My other Bank Account is in BOB but I was not using Mobile Banking on it since the registered mobile no was on ordinary mobile phone.
I tried *99# service on this phone by got Transaction declined message. I called their 1800223344 no and after waiting for long I could talk to customer care person and he told me to activate mobile banking through their ATM. I did it through Net Banking and got m-pin. After 4 hours I could use *99# system on ordinary mobile phone and could transfer money through it to my ICICI Bank.
I am now looking forward to use BHIM app on my smart phone and *99# on ordinary phone for online and offline shopping instead of paytm.
