Hello everybody,
I am using Manjaro (kernel 5.8) with kde/plasma. I have a small “problem”, which I am now trying to solve or at least to better understand. Frequently, the external monitor I plug-in via HDMI cable gets not activated when the linux-system in the meanwhile suspended / slept. I can exclude the monitor itself as the source of the problem as I have tested it with another x86-system.
Until now I see 2 possible reasons for the problem but I am not sure whether it is a) or b):
a) The motherboard / intel HDA / nvidia Geforce mx250 of my laptop does not work properly - somehow the HDMI-port gets deactivated and not activated when it wakes up.
b) There is some bug in my Linux which prevents the system to activate the HDMI-port
I see following possible indications to isolate the problem:
- xrandr shows all the time DP-2 as connected even if the HDMI-cable is unplugged - it seems not to recognize that the monitor is not connected.
- After that problem occurs, I have to shut down my laptop and start it again - then the monitor wakes up. A simple reboot does not wake up the monitor.
- Everytime the problem occurs, the system “forgets” the display resolution I set before for DP-2 - I have to set it again to 1920x1200 via display configuration in systemsettings5
What not helped until now are the following measures:
- Firmware-Update BIOS (to Insyde HP .09 from HP .05)
- Installation of video-hybrid-intel-nvidia-455xx-prime (before I used only video-linux)
- New installation of Manjaro with Kernels 5.4 and 5.8 without any modifications on the system except for audio issues (installation of pulseaudio-git v13.99999…).
- Tried a lot of xrandr / xset commands based on similar problems people discussed about in some forums like:
xrandr --auto
xrandr --output eDP-1 --auto --output DP-2 --auto --left-of eDP-1
xset dpms force off; sleep 5; xset dpms force on
xset dpms force on; xset s reset
The xrandr output when the problem occurs is outlined below:

Could I state: The source of the problem must be the motherboard / intel hda / nvidia mx250 as for linux there is no difference between reboot vs. shutdown + start as the system gets in both cases the same drivers loaded?
Or is there a different way how to find out what the source of the problem is?
Many thanks!
Kind regards,
D.
