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)
Hmm, I can’t say I’ve seen that before. However, it might be worthwhile trying to just boot a live ISO of GNOME (or any other DE) just to rule out a KDE issue. Then if that doesn’t replicate the problem, try a live distro of something with a newer version of KDE (such as Fedora 39).
At the very least, that’ll help narrow down where the problem might be coming from!
It could be some weird sleep behavior bug, or since it’s KDE, it could be another of the 5 gajillion daily bugs of KDE
