Title:
Laptop screen flickering on kernels above 5.4 (not included)
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
