I copied over the physics .bash_profile and .bashrc file to my account.
I tar'd up the .gnome, .gnome2, .gconf, .gconfd, and the .metacity and installed in my account.
The gnome desktop came up fine and is working.
So what could be wrong with the physics account?
I removed all lines from these files and then the physics account would come up.
When the system stops working after the "Switching desktops" icon is pushed:
-move the ~/.pulse file to ~/.pulse-old
-Another sound issue causing problems with physics account
07-23-2014 - Problem faced on two OPIs after they were rebooted and user "physics" tried to login from KDE Login Screen.
When two OPIs were rebooted, kde login screen came up correctly, but user physics was not able to login and start kde session. User root was able to login successfully from KDE login session.
Error message when starting kde session as "physics"
/usr/bin/iceauth: timeout in locking authority file .ICEauthority
logon to lcls-opi30 from ssh session and issue command "dcopserver --nosid"
In case the command runs without issue then ok. Else observe errors.
issue command "strace dcopserver --nosid" to check for warnings errors.
ls -la ~/.ICEauthority
problem was resolved but dont know how!
On a functioning OPI when user "physics" logs in from KDE session, you see following -
