You have been subscribed to a public bug: 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: linux (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment flickering laptop screen -- Laptop screen flickering on kernels above 5.4 (not included) https://bugs.launchpad.net/bugs/1940285 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
