Summary: Plasma fails to turn off external monitor
Classification: Plasma
Product: plasmashell
Version: 6.1.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

SUMMARY
Power management is configured as follows:
When laptop lid is closed: Turn Off Screen
[x] Even when external monitor is connected
Now, when I close the lid external monitor turns off (entering sleep mode) and
then after a few seconds turns back on.
I don't know if it is relevant but my laptop has Hybrid graphics (Intel+Nvidia)
configured in PRIME mode as per https://wiki.archlinux.org/title/PRIME so only
Intel is active.
STEPS TO REPRODUCE
1. Have a laptop with hybrid graphics and external display
2. Connect external display via HDMI
3. Configure Display Configuration: External monitor to be the only one enabled
4. Configure Power Management: When laptop lid is closed: Turn Off Screen
5. Configure Power Management: Check "Even when external monitor is connected"
6. Close the lid
OBSERVED RESULT
Monitor turns off, then after a few seconds turns back on.
EXPECTED RESULT
Monitor turns off.
