Hello, (I’m new to OMLx/Plasma6) when my monitor is turned off then back on again, I get a black screen.
I leave my PC on 24/7 but turn off the monitor when away from the system, as I’ve done for many years. But with OMLx if I turn the monitor off then back on, I get a black screen, no matter how brief a time the monitor is off.
This black screen has peculiar properties:
the mouse arrow icon is visible and ‘alive’
if I had a window open - say, a browser - this window is still active but on a black background
pressing the ‘winkey’ on the keyboard brings up the application menu as usual
pressing ctrl-alt-delete brings up a sleep-restart-shut down-logout-cancel menu
It’s as if the OMLx/Plasma screen is hiding behind a curtain!
Your help would be much appreciated because I very much like the OMLx environment but the black-screen-issue renders it useless
My hardware/OS:
Acer AOPEN 27AS2 Ebi 27" montitor connected via HDMI to a
Beelink EQ12 mini PC (Intel Alder Lake N1000 with UHD Graphics, 16 GB DDR5, 500 GB M.2 SSD) running
Linux core 6.1 OpenMandriva ROME 25.1 with Plasma 6 D.E. accessed via
GRUB Linux/MS W11 dual boot
Thanks for responding.
I’ve been using Ubuntu/Mate for years where I’ve never see the terms X11/Wayland discussed. I assume they’re something to do with the graphics rendering engine, but have no idea what they imply in this new-to-me OM/Plasma context.
You can also run the following command in the terminal to find out whether you are running X11 or Wayland.
Open Konsole (the terminal) by pressing ctrl+alt+t all at the same time or look for Konsole in the menu.
echo $XDG_SESSION_TYPE
This should give the output of the session you are currently running.
Thanks; my ‘Graphics Platform’ is X11.
When installing from the distro I didn’t get prompted to choose the graphics system, nor did the documentation explain the difference between X11 and Wayland.
Now that you mention it, I don’t think I had an option between Wayland or X11 when I installed OMLx several weeks ago. Mine defaulted to Wayland, just like yours.
Arggggh… thanks for the question!
If I select Settings>System Settings>Screen Locking>Lock screen automatically>after 1 minute it does >not< result in the black-screen-of-death; instead, a screen with the time/date at the top and flower in bottom right pops up and pressing any key brings up a request for the password as if I had logged out, and restarts as if I’d logged out.
If I select Settings>System Settings>Power Management>Suspend Session>When Inactive>Sleep>After 1 minute I get the same black-screen-of-death that I get when I turn of the monitor and turn it back on - and! - the monitor’s power led turns from blue to red! It’s evident that the simple fact of turning off the monitor somehow triggers a software response that has never occurred in any other system I’ve used.
I prolly didnt run into this because no matter the distro I’m on I always set my screen to stay on all the time as well.
Im the only one in my home office so I dont care about leaving it open all the time.
