Summary: Suspend fails due to QQuickPixmapRea
Classification: Plasma
Product: plasmashell
Version: 6.0.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED

Journalctl logs
SUMMARY:
Whenever I try to suspend, there's chance that the suspension fails.
It goes to SDDM and the screen becomes very dark, but the system doesn’t
actually suspends. It stays on a “fake” suspend state. I don’t get video
signal, nor any way of getting commands or TTY going.
The only option I have is to force restart the PC.
I've exported the journal ctl logs to see what caused the problem and I've
traced to the user space failing to freeze processes due to a task called
“QQuickPixmapRea”, of which there's no documentation on what it does (I looked
everywhere and the closest was QtQuick).
STEPS TO REPRODUCE:
1. Suspend.
OBSERVED RESULT:
It goes to SDDM, the screen gets very dark and the system becomes very quiet.
Clicking on the power button to resume suspend makes the system active, but I
get no video signal. I'm unable to get anything or a TTY going.
EXPECTED RESULT:
It goes to SDDM and the screen becomes black. The system suspends and the
status light on the tower starts blinking.
SOFTWARE/OS VERSIONS:
Linux/KDE Plasma: Fedora 40 KDE
KDE Plasma Version: 6.0.4
KDE Frameworks Version: 6.1.0
Qt Version: 6.7.0
ADDITIONAL INFORMATION:
- This also occurs on OpenSUSE Tumbleweed and possibly any Linux distro that
uses KDE Plasma.
- It also occurs on KDE Plasma 5.27.
- Secure boot is disabled.
- WiFi is off and so is Bluetooth.
- I can wait 30 minutes to suspend, but it never does.
- It happens regardless if I have a ton of apps or no apps launched.
- Result from `inxi -aFz`:
