Hi,
I’ve recently reinstalled Manjaro on my Asus Zenbook UX391UA. I had used it an year or so back and it used to work fine and I went distro hopping and now I’m back here.
I got a solution to the screen flickering from https://wiki.archlinux.org/title/ASUS_Zenbook_UX391. Doing this resolves this issue, but once I add the entry and reboot, within a few minutes, the system freezes, and after about 30-60 seconds, the laptop reboots.
Can I please know what to do to fix the screen flickering other than this method?
I also didn’t know how to boot into that to at least get logs or something because many times, the laptop reboots on the login screen itself.
Hi, thank you very much for the reply! Main update: I’ve seen that adding the intel_idle.max_cstate=4 to grub doesn’t remove the random restart. It seems that the random restart is a separate problem irrespective of whether I add or remove it (it was just coincidence that the PC worked without it and didn’t work with it).
Whenever the PC hangs, it becomes fully irresponsive. REISUB doesn’t work and restarts automatically. From what I saw, it seemed like a kernel panic, but the power button’s light/caps lock button’s light do not blink or anything.

Sometimes after the restart, I’m still not able to go back into the laptop, so getting logs is also difficult. Please let me know if I have to move this from display to some other category.

This is the only thing that I got. I had attached it in the previous reply, but I didn’t know how to tag it now.
Also, can you please let me know how to update my firmware? I’m sorry if I sound dumb.
I’ve updated the BIOS. I’ll report in a day’s time if there are any issues or if everything got fixed!

Sorry, I didn’t see the difference, I thought you accidentally missed it in the first reply
On a separate note, after I updated my BIOS, both the screen flickering and the random restart hasn’t occurred in 3-4 boots that I did after the update. It seems to have fixed everything, but I’m not able to say for sure. If the problem doesn’t occur for 1 more day, I guess it is safe to assume it fixed all the issues and I’ll mark it as the solution.
Welcome back to Manjaro!
