So I recently installed Ubuntu onto my laptop and everything was working fine except for one thing I noticed that my games were running brutally slow, so I asked my friend for advice and he suggested I use this line of code
sudo apt-get install nvidia-current
in terminal to update my Nvidia Graphics card drivers. So I installed that and then noticed that my games and Blender wouldn't even launch any more, they would for about a second and then just close. So I used this code
sudo apt-get purge nvidia-current
to uninstall the Nvidia driver update my friend suggested. After that I tried multiple other Nvidia driver updates people suggested online but non of them has fixed the problem.
