Bug ID: 515550
Summary: Screens don't light up automatically after waking up
(resuming) from suspend to RAM (sleep) when using
Wayland
Classification: Plasma
Product: kwin
Version First 6.5.5
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Screens don't light up after resuming until I hit my keyboard.
I was able to reproduce this issue using either only my laptop's internal
screen while running on battery, or only external monitors while running on
power adapter (clamshell mode).
I enabled Powerdevil Full Debug log and captured logs in both scenarios.
STEPS TO REPRODUCE (Internal screen)
1. Close lid to sleep
2. Open lid. It wakes up but the screen's black
3. Hit any key on the keyboard, the internal screen will light up
The laptop was running on battery and
/sys/bus/pci/devices/0000:01:00.0/power/runtime_status said 'suspended'.
STEPS TO REPRODUCE (External monitors, clamshell mode)
1. Sleep (Krunner -> Sleep)
2. Wake up the laptop using either keyboard or Wake-on-LAN
3. All displays, including the laptop's internal one, stay black
4. Hit any key on the keyboard, external displays will light up
Two displays connected via HDMI and USB-C (DP Alt) each.
/sys/bus/pci/devices/0000:01:00.0/power/runtime_status said 'active' (HDMI and
DP are wired to the NVIDIA card).
I opened my laptop's lid to reach the internal keyboard in Step 3, so that the
'Lid opened / closed' logs could serve as dividers.
OBSERVED RESULT
Screens don't light up until there are some user interactions.
EXPECTED RESULT
Screens light up automatically.
