show login screen
Classification: Plasma
Product: plasmashell
Version First 6.4.5
Reported In:

Sleep and log in cycle where this happens
SUMMARY
When waking from deep sleep (suspend to ram), most times the display turns on
to a black/blank screen. Pressing any key on the keyboard will then show the
login screen as expected. This seems to me to be some sort of race condition,
maybe between dGPU and iGPU, but I'm not smart enough to understand my logs
completely
STEPS TO REPRODUCE
1. Suspend to ram
2. Wake PC
3. Do not press anything
OBSERVED RESULT
A blank/black screen, clearly backlit but not updating to show login screen
EXPECTED RESULT
The login screen ready for input
