I have upgraded from 17.04 to 17.10 recently and am experiencing major graphics issues since. First, the system was booting to a black screen with some log file flickering up every few seconds (containing Apache status etc.). However, I could open a TTY by pressing Ctrl+Alt+F2 and after some research I found out that I had to uninstall the NVIDIA drivers which I had been working with for several years without problems.
sudo apt-get purge nvidia*
solved my problem, however I had to switch from Wayland to Xorg in addition to fix a laggy mouse and keyboard. Now, the system works fine, except for animations (like the app menu or scrolling in Google Chrome) being extremely laggy which I think is due to the missing NVIDIA drivier. I tried reinstalling the proprietary driver (384.90) in the "Additional Drivers" section in the update settings, which resulted in the same black screen error I mentioned above, so I had to uninstall the driver again.
Is there already a known fix to use the NVIDIA driver with Ubuntu 17.10 or any other way to make animations smooth again?
EDIT I tried uncommenting the line "WaylandEnable=false", as it was suggested to another person with a similar issue. Unfortunately, this did not work for me.
# WaylandEnable=false
line, the problem persists.
