I'm running 12.10 64 bit on a Dell E5410 Latitude. Everything was working nicely until I tried to install Avast antivirus program. This froze my system and I proceeded to remove --purge the program.
Now I'm in the situation that at the login screen I can no longer use my standard (admin) user accounts through the graphical interface. When I enter my password the screen goes black flashes code for a milisecond and then returns to the unity login screen. using an alternative terminal (i.e. ALT+F3) I can login normally. using my guest account I can also login to graphics mode without an issue.
unity --reset, the out put is shown as "The reset option is now deprecated"
I'm hesitant to start messing with ccsm for the moment as it sounds like I could potentially do more harm then good.
the '.xsession-errors' (which I can only access from the guest account) does not make me any wiser. Neither does the '/var/log/Xorg.0.log' provide any obvious clue.
I have no idea if I'm even on the right track and feel that my google and forum searches are no longer giving me more clarity. hoping some one can help with this.
All the best from Malawi, Daniel
