I'd like to start by thanking all of you guys for the great community - I have learned a lot going through the questions and trying solutions. I am stumped on this current error and would greatly appreciate your help and thoughts.
The background is that I installed the ATI 12.8 drivers for my 7950. On reboot this led to the tty1 screen without going to the login screen (not going to lightdm); I uninstalled the proprietary driver and fglrx as per question1 and question2
Now on reboot, it launches lightdm's login screen, but I am now in a login loop. I have verified the ownership of my .Xauthority file as user1 as well as the rest of /home/user1/ as per question3 but this has not fixed the login loop. I believe it is still a driver/graphics card problem but am lost on how to proceed.
Here are my .xsessions-error and Xorg.0.log files:
No protocol specified No protocol specified xrdb: Resource temporarily unavailable xrdb: Can't open display ':0' No protocol specified No protocol specified xhost: unable to open display ":0" No protocol specified No protocol specified xhost: unable to open display ":0" openConnection: connect: No such file or directory cannot connect to brltty at :0 No protocol specified No protocol specified No protocol specified No protocol specified ** (gnome-session:2257): WARNING **: Cannot open display:

Thanks again for all your help.
