Hi,
A few days ago, I switched from Ubuntu to Manjaro. I love it except this flickering issue. I have a Dell Latitude 5490 laptop, and 10 seconds or so before the Manjaro login screen, the screen goes crazy with purple and white and green lines flickering all over the screen. This flickering happens every time I boot, but about 30% of the time, it ends with a black screen and I have to simply power cycle the machine to turn it on. I also got the black screen once after I suspended. Additionally, if I hit Ctrl-Alt-F2 to go into TTY mode, the screen does the same thing, and after 10-20 seconds, it typically will again go black and I have to power off/on.
This is dual boot with Windows 10, and I don’t see the problem when I boot into Windows, nor did I see it when I was using Ubuntu on this machine. So I know there has to be some setting that will fix this!
I’ve tried:
- Different kernels: 5.13, 5.10, 5.4
- Setting the refresh rate to 50 Hz
- Setting the kernel option: i915.enable_psr=0
So far, no luck. The exact same problem persists.
Any help would be greatly appreciated.
