Public bug reported: Recently, I installed Ubuntu 21.04 on my laptop and I was having the same problem I had like with others distros such as Fedora; for some reason, the screen just ramdonly and briefly turns off, (more like a flickering) and it also "autoregulates" a the brightness, just a little bit down and then a little bit up.
I noticed I don't have this problem on Linux Mint, and I also noticed that going back to Kernel 5.8 on either Ubuntu 21.04 or 20.04.2 this problem stops. I have been using Mainline ( https://github.com/bkw777/mainline ) to install previous kernels (5.8 and 5.4 wok just fine, but anything above this problem comes again). Thanks so much beforehand. ** Affects: ubuntu Importance: Undecided Status: New ** Tags: flickering laptop screen -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940285 Title: Laptop screen flickering on kernels above 5.4 (not included) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1940285/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
