2. Resume system from sleep after monitor goes blank

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Manjaro Linux KDE
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.20.0
Qt Version: 6.10.1
ADDITIONAL INFORMATION
This bug was not present in KDE Plasma 6.3.
Bug seems to be present after upgrading to 6.5
Bug was present on 6.5.3 and 6.5.4
For context I have an Nvidia GeForce RTX 5090 laptop, and it is not an Nvidia
driver issue as the driver remained the same but only KDE Plasma was updated. I
tried upgrading the Nvidia driver just to see if the issue was fixed but it
still persists. I can confidently say that this is definitely a KDE bug and not
an Nvidia bug.
