My Ubuntu 16.04 system was running OK until I allowed today's update. After the system reboot, I am not able to log in using GUI. After entering in my password, the system will pause, then after a bit the screen will go black, and then return to the login screen. One of the updates was an nvidia driver update nvidia-current:amd64 (304.131-0ubuntu3, 304.132-0ubuntu0.16.04.2) from /var/log/apt/history.log
When I remove the nvidia using
$ sudo apt purge nvidia-*
The following packages will be REMOVED:
nvidia-304* nvidia-common* nvidia-current* nvidia-opencl-icd-304*
nvidia-settings*
the system works, although I think this is using base graphics. When I reinstall using
$ sudo apt-get install nvidia-current nvidia-settings
The following additional packages will be installed:
nvidia-304 nvidia-opencl-icd-304
The following NEW packages will be installed:
nvidia-304 nvidia-current nvidia-opencl-icd-304 nvidia-settings
the system no longer logs in and is bad as before.
Some system info:
$ lspci | grep VGA
05:00.0 VGA compatible controller: NVIDIA Corporation G98 [Quadro NVS 420] (rev a1)
$ ls -latr .Xauthority
-rw------- 1 gallagherlab gallagherlab 86 Nov 4 14:25 .Xauthority
below did not change anything, bad permissions persist after reboot
rm .Xauthority
sudo chown -R $USER:$USER $HOME
chmod +x -R $HOME
I tried to install back to 304.131-0ubuntu3 using .run file but ran into X issues.
Any help to get this fixed would be appreciated.
