Good day, folks!

I hope you won’t mind helping me with some troubleshooting.

I currently run Debian 13 Stable with KDE Plasma (Wayland). I have an Asus laptop with an AMD Vega integrated GPU and an Nvidia 2060 Mobile dedicated GPU.

Error shown in the attached GIF. Had to shorten it, but the flickering repeats non stop.

First of all, I’m sorry I can’t provide you with a video; I tried attaching it to the post but won’t let me attach any other than photos.

This issue shows up at random: when closing the lid and thus leaving the system suspended, I later open it up to continue using it and the bug manifests. The screen brightness ‘flashes’ and increasing or decreasing brightness manually doesn’t solve it. Most times, it suffices with closing the lid and opening it up again for the issue to disappear and, for the times it doesn’t work, a reboot is needed.

Now, one might think that this is an Nvidia driver-related issue. While I currently haven’t installed the proprietary driver and, thus, I suppose the open source Nouveau driver is in place instead, what makes me discard that possibility is that, prior to Debian, I tried Ubuntu and Mint (based on the former), in both of which I did install such Nvidia drivers, and the exact same issue occurred.

As far as I know, the AMD drivers are included with the Linux kernel, so that shouldn’t be the issue (?)

It doesn’t seem to be a Wayland issue either, since I’ve tried both X11 and Wayland, the issue showing up on both.

Finally, if it’s worth mentioning, this issue didn’t happen back on Windows. Not that I am planning on going back, rest assured.

I am thus out of ideas as to what might be causing this or what else try to do. I appreciate any clues you could provide me with.

Thank you in advance :)
