[Bug 1876487] Re: The screen is blinking at a random time
Thanks for your advice, I'll try to get the journal next time. Unfortunately, this bug appearing not so often, and changing my desktop environment and be awaiting it around a couple of couple weeks is not very convenient for me. I'd suggest thinking about other ways of testing than the first two. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876487 Title: The screen is blinking at a random time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1876487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It looks like visual bell goes crazy (but I'm not sure in that). And yes, I love visual bell and usually do enable visual bell instead of audio bell. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876487 Title: The screen is blinking at a random time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1876487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1876487] [NEW] The screen is blinking at a random time
Public bug reported: I've seen this error on Dell Latitude E7270 (with an internal video card) as well as Dell Precision 7540 (with NVidia card). I've seen this error on Ubuntu 18.04 and now on 20.04 I've never reported it yet but I think the time has come. In a random time (~ once a couple of weeks) I see a blinking screen. Today I've recorded a video on my phone to show you how it looks. You can see it here: https://youtu.be/JiUu7Ydg6uM This is bug finishes when I do logout from my desktop. Could you help me eliminate this error?
