I occasionally have an error where:
– I try to log into Ubuntu Unity Desktop
– I type in password successfully
– After a few seconds the screen flickers and I am taken back to the login prompt.
This problem is caused by an NVidia driver problems. For some reason it can go missing.
Fix by:
– Going to TTY
– Logging in
sudo service lightdm stop
– Go to my installation files folder, and running the NVidia driver installation file
– When it asks if I want to make changes to XConfig, say no, or it will break the system and you’ll get lots of boot problems.
