From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

AMD+Wayland+dual monitor = Screen flickering (lemm.ee)

So...I have an...interesting behavior I've never had before with an Nvidia or integrated intel chipsets...I have now my AMD card plugged both to a normal HDMI monitor, and then to another HDMI TV. Both work well. However, when I turn the TV off... The monitor will start flickering. About three flickers every minute or so. It's not a signal loss also, I can see it's drawing for a brief split second the windows that were drawing on the TV area, so it's kinda rearranging the whole desktop area...then it resets. It does this 3 times, the whole ordeal last a couple seconds, in which everything is unusable because of the flicker, and focus going to all sorts of places. If I turn the TV back on, the behavior stops immediately.

Any idea what's causing this, and how can I sort it out? I'm using KDE Neon latest (it's still Ubuntu 22.04), with an AMD 7800XT, with kisak's ppa. Running an updated kernel 6.5.0-1007-oem. (I followed these instructions to get it working at all)

That sounds like your TV is temporarily disconnecting at random, or at least doing something that the GPU detects as a disconnect.

Most likely, AMD's hotplug detection is too aggressive. You can report that at https://gitlab.freedesktop.org/drm/amd/-/issues
