Screen flicker even with latest Ubuntu and popular laptop
2 by mazugrin2 | 0 comments on Hacker News.
I'm using Ubuntu 21.10 and a modern Dell laptop (XPS 13, 7390) and still have to add a kernel parameter (i915.enable_psr=0) to get my computer to work correctly. Actually, it turns out that I need this kernel param on my work laptop too, which is another popular Dell Latitude laptop. This has been required for over a year now, despite keeping up with all the OS updates. Why is this still happening? I appreciate all the volunteers working on Linux, but do none of them use popular hardware?
