[Bug 1917101] Re: Booting into desktop results in flickering (also when I turn off and next turn on display)
Top right you should see a "Padlock This report contains Public Information Padlock" type area which you can change to a higher setting... Too high though and other users of launchpad won't be able to see it and click the "affects me too" providing the confirmation required for it to get attention (currently it impacts only 1 user; contrast with bug 1838644 you mention which currently has 3 impacted users thus more heat, plus it has the apport details provided) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1917101 Title: Booting into desktop results in flickering (also when I turn off and next turn on display) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.4/+bug/1917101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed: Dear Launchpad Community, I have problem with my display on all version of Ubuntu system. It doesn't matter what version I will install. I checked this on Ubuntu 18.04.5, Ubuntu 20.04, Ubuntu 20.04.1, Lubuntu 18.04.5. My screen is flashing for one second when I boot my system or if I will turn off and next turn on my display. My screen is flashing (white image) for one second. What is a problem? I think that this can be driver problem or with kernel itself. I have this same problem on other computer.

@guiverc this is not problem only with Lubuntu. I have this same issue on second computer with installed Ubuntu 18.04.5.

Lubuntu 18.04 is EOL (see https://lubuntu.me/bionic-eol/) as flavors only provide 3 years of supported life (using packages found in 'universe'). Main Ubuntu Desktop, Server and packages from 'main', which include the kernel you're asking do have 5 years of support with regards security fixes. I had a quick look at your video, I couldn't see the issue you're talking about, but Lubuntu 18.04 is no longer supported. The Ubuntu/Canonical team however will require the apport-collect to be actioned. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1917101 Title: Booting into desktop results in flickering (also when I turn off and next turn on display) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.4/+bug/1917101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
