I recently change my proprietary driver to NVIDIA, and then I got a screen problem that I don't know how to describe but there are some parts of the screen flickering whenever I move something. Please help me.

The problem

FYI : I am on Ubuntu 18.04, KDE 5.12.9, and my NVIDIA driver version is 390. The problem only occurs when I use the NVIDIA driver, Nouveau driver is doing fine.

What I have tried :

  • Changing Tearing prevention("vsync") to Full Screen Repaint
  • Adding kwin.sh file to profile.d folder
  • Changing Rendering backend to XRender, it works but I want some animation on my desktop

Thanks in advance, Let me know if there is other information I should provide.

  • Does this solve your problem? – singrium Feb 18 '20 at 13:44
  • @singrium Thank you for your reply, sir. Unfortunately, they didn't work, I have tried adding the command but it didn't work. I also tried using compton, but somehow the problem got worse (more lag and screen tearing). I am not exactly sure though, maybe I added the command in the wrong way because the steps explained didn't match with KDE (and the video too). Thanks for your time anyway. – IrvineL Feb 18 '20 at 15:45
  • Hmm, did you check this question? – singrium Feb 18 '20 at 16:05
  • Also try this: 1) Open Nvidia X Server Settings. 2) Go to OpenGL Setting. 3) Uncheck Allow Flipping.
    Source: video. Try this first.     – singrium Feb 18 '20 at 16:11
  • @singrium I just noticed that there is an error when I add the command using crontab, the error is : crontab: installing new crontab "/tmp/crontab.413DOW/crontab":2: bad minute errors in crontab file, can't install. – IrvineL Feb 18 '20 at 16:13
  • @singrium Yes I have checked it, but unfortunately it doesn't work too. – IrvineL Feb 18 '20 at 16:22
  • This is strange, because it worked with others. Are you sure you copied the same command? Meanwhile, check my previous comment with the video link, it describes another method to solve flickering problem – singrium Feb 18 '20 at 16:22
  • @singrium hmm, my Nvidia X Server Settings doesn't have the Allow flipping option. – IrvineL Feb 18 '20 at 16:23
  • I noticed that you're using Nvidia-Driver-390, which is a legacy version, why don't you update to the latest driver? It may solve the problem – singrium Feb 18 '20 at 16:24
  • @singrium if you meant the comment by E Falegmane in the youtube comment, I didn't have those options too – IrvineL Feb 18 '20 at 16:27
  • @singrium Ok, I will try updating the driver, thanks for your suggestion. – IrvineL Feb 18 '20 at 16:29
