So, I’ve been running into the same issue constantly for the last 3 months and when my PC decides to sleep after not being used. The monitors sleeps and monitors stay sleeping or visual bug out and I have no way to enter back to my screen without me restarting the PC.
There is nowhere near enough information here for anybody to help, at all.
What hardware? What configurations and resolutions?
We get that you’re using Tumbleweed and Plasma, but that’s not nearly enough to even begin to guess at what your issue might be.
2 screens 165hz 2560x1440
My hardware is a Ryzen 7 5800X, 32GB of Ram DDR4 3600MHz and a RX 7800XT Graphics card.
Lock screen Automatically: Never
power management:
After a period of Inactivity: Do Nothing
and it still places my monitors in sleep
Power Management in your monitors themselves? I’m not saying I’ve got any solutions for you, as I’m not sitting in front of your computer.
I don’t know if something like corectrl would allow you to tweak the power management settings on the video card itself, but it’s a possibility.
Might even potentially be some power control settings in your machines BIOS, or in power-profiles-daemon
or tlp
or whatever the heck it is that systemd offers for power management (That I currently can’t remember the name of “tuned” maybe?)
If this is using Wayland, try X11 instead; or vice versa. Does it make any difference?
Try creating /etc/X11/xorg.conf.d/50-0dpms.conf containing the following:
Section "Monitor"
Identifier "DefaultMonitor"
Option "DPMS" "off"
EndSection
I’ve checked the power management in the monitors and they are as the same to never technically shut off or sleep unless I manually press it.
I’ve just checked it out and doesn’t seem to be, I’ll have to double check the BIOS later then.
I’m using X11, so I’d have to install Wayland then. I’ll update here when I know more
I don’t believe it’s possible to not have Wayland automatically also if you have X11. At your SDDM login screen there is a menu to choose which. If you use auto-login, then you need to log out without shutdown or reboot to make the choice.
It’s an AMD + Linux + KDE Plasma “feature” …

If I leave the machine for some time – with or without locking the screen – <Meta+L> – waking the screen up from it’s (deep) sleep mode can take some time –
- As a last resort, I quite often have to press the power button on the screen to power it off and then power it back on again …
