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
