[Bug 1830358] Re: Screen flickering
Thanks for the video! This kind of flickering is going to be low-level. So we should look at the kernel log. If the kernel driver isn't reporting errors then it would probably be a hardware fault. Please wait until the problem happens again and then run: dmesg > dmesgonflicker.txt and send us the file 'dmesgonflicker.txt'. ** Package changed: ubuntu => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830358 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1830358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1830358] Re: Screen flickering
Here's a video of the issue: https://youtu.be/DNdWc5aqPoo Having spent time with this issue here are my observations. Issue comes and goes. Issue manifests itself in 3 ways: 1. Most commonly (several times a day) I see what is shown in the video, intermittent blinking differently spaced out. Lasts anywhere from 30 seconds to 2 minutes. 2. Much more rarely(once every week) I see total screen failure. Screen replicates and/or stretches on itself and can't do anything. Lasts for about 10-20 seconds. Then it returns to normal. 3. Even more rarely (once a month) the screen turns off. The solution here is to close the laptop and open it back up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830358 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1830358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes I know, that's why I said video.

Flickering is not visible during screen capture. The most flickering I encounter is when scrolling a new html page. The more images on it the more it seems to flicker. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830358 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1830358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Please try to take a video of the problem and attach it here. A video is important because it tells us what type of "flickering" we are dealing with. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830358 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1830358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
