I followed this tutorial that is supposed to help with screen issues when using Nvidia. See here - https://www.gloriouseggroll.tv/2016-arch-linux-nvidia-get-rid-of-screen-tearing-and-stuttering/
I followed all that and when I rebooted, cinnamon just kept crashing and I was stuck with just my wallpaper. I was able to use CTRL-ALT-F2 to get to the terminal and undo these changes but I am curious about what went wrong.
I do know that the guy in the video had extra stuff within his /etc/X11/xorg.conf file (besides what he said to add). At the same time I had to create my file and he already had his.
Sadly I was more concerned with getting my system back that I didn’t really track which thing I undid fixed the problem. So I am not sure what file or change caused the problem.
If there are any ideas here that would be great. I don’t have major screen issues but some youtube videos do seem choppy, and when I have my screensaver load (the default, where it fades in to the darker screen and clock) it flickers first before doing the nice fade. There are minor things like that I am looking to fix.
