Recently on every startup I get error unable to detect graphics settings (this is from memory, so the message is not exact).
I am then offered to run in low-graphics mode for one session (other options offered do not work). Since this mode is perfectly fine, I would like to set it to run always without those error messages. How to do that?
The error in logs that I am given access to at that point is: x server is already running and goes on about existing .lock file.
Update. It seems that removing lightdm solved the issue for me, getting me exactly what i wanted.
