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.

KDE intermittent desktop flickering after monitors wake up from suspend (lemmy.world)

I’m having an issue with my desktop flickering after my monitors wake up on KDE. When I first turn on my PC it’s fine, but if I walk away and let the monitors turn off when I then come back the desktop starts flickering. It’s only the desktop that flickers, if I have an app open full screen it’s fine but as soon as I minimise it the flickering comes back. It doesn’t seem to be an issue if I leave it long enough for my actual PC to go to sleep, only the monitor. This happens on both Wayland and X11.

Does anyone have any ideas on how to fix this, and if not is it worth submitting a bug report on kde? Or is it probably just something dodgy in my setup? This is with an Nvidia GPU which I suspect has something to do with it (I’ve tried with both the nvidia and nvidia-open drivers). I’ve already had to change the settings so that the screen locks before the monitors sleep otherwise it was causing kwin to crash and I’d get stuck at the login screen for a minute after resuming.

It's possible your screens electrically disconnect themselves when going to sleep, which makes Plasma refresh its desktop layout, causing flickering.

My Asus screen does this when powered off but not in standby. That used to crash Plasma Wayland back in 5.24 lol

How would I tell if that’s the case? And I guess there’s nothing I can do about it if that is the cause?
