I'm trying to install the CUDA drivers for Nvidia GPU on ubuntu 16.04. In order to do this I need to kill server-X by pressing Ctrl+Shift+F1 and run
sudo lightdm stop
The first time I did this it worked normally. However I don't know if I messed with something buggy or what related to the graphics driver, everytime I run this in TTY mode I get the same error as in How to fix “The system is running in low-graphics mode” error?. The only difference is that when I reboot things are back to normal.
Does anyone have an idea to fix this, such as a reparing/update of some sort? I'm also considering completally reseting Ubuntu.
Honestly after hours trying to figure this out just to installing a simple drive I'm very upset. I don't understand why Ubuntu has to be so freaking complicated.
