--- Comment #5 from Mathias <math...@public-ip.org> ---
I can confirm this on two separate Desktop PCs with external Monitors connected
via HDMI to Intel GPUs:
1. Start Plasma session, open programs/windows
2. Switch Monitor off and on again
3. Panel and Background are gone, but windows of open programs are present,
mouse and keyboard are functional
4. to restore panel and background: open console in same VT, issue
'plasma-shell --replace'
5. when starting over from 2 again, the plasmashell running in the console
gives the same message as OP:
kde.plasmashell: requesting unexisting screen available rect -1
Reproducible always.
At least also Plasma 6.2.4 was affected by this.
There are no error messages in the logs, and the plasmashell process is not
crashing, it remains running.
Possibly relevant: In one of the setups, the monitor is not connected directly
but via a KVM switch. In this case, powercycling the monitor shows no problem,
but powercycling the KVM switch. While mouse and keyboard come back without a
problem, the monitor stays completely blank. Because of this, I can also not
restart the plasmashell. I can switch to a text-only virtual terminal but the
graphical virtual terminal (vt 7) remains without signal. I can only bring it
back by restarting X from the text terminal.
SOFTWARE/OS/HARDWARE:
Gentoo Linux
Kernel 6.12.16
Plasma 6.2.5-r1
KDE Framework: 6.10.0
Graphics: X11
CPU: Intel Core i5 and i7
GPU: Intel onboard UHD Graphics (driver: i915), connection: HDMI
Please let me know if I can test anything else to identify the cause.
