Seems like years that kscreen has been a problem.
In 2018 I had a laptop (nVidia and Intel) and when I attached my external monitor, kscreen would always attach it at 60hz which was unsupported by that monitor and so would have a blank screen. Just for fun, it or whatever also moved the desktop to that monitor so i couldn't fix it. I finally gave up, uninstalled kscreen and used an xrandr script to correctly set the refresh rate and resolution when the monitor was attached. My solution worked great, but annoying that kscreen totally failed to do it's one and only task.
In 22.04 it's no better. I have dual monitors now on a desktop (AMD RX580) and screen power-saving with kscreen installed causes the whole thing to go wonky. Sometimes neither screen blanks at all. Sometimes the left screen (primary) blanks and the other doesn't. Sometimes they both blank but the monitors are re-arranged to mirror each other instead of side-by-side as they were configured. Additionally, I think sometimes else is at play because screen blanking (when it doesn't do any of the above) will sometimes move all the open windows to the right (non-primary) monitor.
Annoying as all get-out <insert numerous swears here>
SINCE I now have 4k monitors I need kscreen to set scaling. Luckily, whatever I set scaling at remains set even after kcreeen is removed. So I install kscreen, make adjustments, and uninstall it. I've been plating with DPI, scaling, and a couple other setting to get the desktop text readable but still retain as much added screen real estate as possible.
Uninstalling kscreen returns normal (mostly) screen blanking behavior wiht the exception of the mysteriously shifting windows. Sigh...
I know I can just - once again - write an xrandr configuration or a full xorg.conf and be done with it, but that feels so 2010. Ever the optimist, I keep thinking the next plasma update will FINALLY fix kscreen. I'm still waiting.
