Screen Flicker Randomly Ubuntu

Screen randomly flickers when I’m in the middle of something. Seems to go away more reliably if I move the mouse around. Could be 10-15 minutes before I see it again, could see it right away again. It’s quite sporadic.

Bueller?

This is expected, you will need explicit sync support to get rid of this.

On Nvidia’s side, that’s waiting for 555 series driver (and some bits in 560), so that’s an entire month away just for the beta release.

You could try using the Wayland session + apps in Wayland (not XWayland) + your current 535 driver to attempt to work around it, but upgrade to Ubuntu 24.04 first before doing that(to be released in a week), otherwise you’re going to have a very bad time.

Hello @C0rn3j , could you please help me check if what I encountered is also expected?

A few days ago, I updated my Ubuntu 22.04.1 without paying much attention to the automatic update messages. Ever since then, I’ve been experiencing screen flickering issues with my NetBeans IDE 21. The problem seems to extend to other JetBrains CLion IDE and jEdit text editor as well, although other applications like Firefox are unaffected.

I’ve recorded the screen flickering, and you can check it out in this Google Drive *.mov file and this one. As for system details, my memory usage stands at 7.38GB out of 126GB, and I’m running Linux kernel version 6.5.0-28-generic.

I’ve searched online for solutions but haven’t had any luck so far. Could you please take a look at this issue for me?

Below is my current setup.

  • Ubuntu 22.04.01 x84_64
  • Nvidia 535.171.04
  • 1920 x 1080 @ 60Hz and 50Hz
  • RTX 4060 Ti
  • X11

Here is the log report. Somehow there is no response in uploading the file, so I upload to Google drive. Hopefully, it helps investigate the issue.

I would retry with 550.76 (and keep X, as 2022 Ubuntu is not ready for anything Wayland)

Hello @C0rn3j,

Thank you so much for your prompt reply! I have been struggling with this issue for several days. I will back up the system and retry with 550.75 and let you know. Thanks again!

By the way, I just uploaded the nvidia-bug-report.log.gz here. Somehow I can’t upload to this forum, so I put it on my Google drive. I hope it helps! Thank you.
