Yesterday evening i was speaking to my friend in SJPHONE via ‘SIP’ port, all of a sudden my system got hanged due the network problem and then i was forced to shutdown my pc.
After I reboot, i found all the session where opened automatically as it was before shutting down and everytime i boot my pc the session never closed automatically.
I’ve found that gnome-session doesn’t properly handle turning off automatic session saving.
Then I read a bug report Bug#34321 at lanchpad.net and solved my problem.
My problem solved by following below steps
1. Turn off auto_save_session via gconf-editor.
2. Closed all apps.
3. then manually deleted ~/.gnome2/session file.
4. reboot the system.
Now it is working fine !!!
I sincerely thank lanchpad.net and my friend Shrinivasan for helping me to solve this problem.
