HDMI monitor does not turn on a new install

tmske · 2020-12-27 08:49:46

Hi,

I've done a new installation of archlinux on a newly build desktop pc.
My graphics card is a Nvidia GeForce 1030 and my monitor is connected with HDMI (I don't have any other options at the moment). On starting Xorg my monitor turns blank (sometimes the screen flickers for a very brief moment).

08:00.0 VGA compatible controller: NVIDIA Corporation GP108 [GeForce GT 1030] (rev a1)
        Subsystem: Gigabyte Technology Co., Ltd Device 375c
        Kernel driver in use: nvidia
        Kernel modules: nouveau, nvidia_drm, nvidia

I've found 2 similar issues without a solution:

By reading these I've found that it's probably an issue with HDMI and I've been able to find a workaround by letting my monitor show 2 sources at the same time. I guess that means that my monitor won't turn off (because it needs to show the second connection as well).

I have installed plasma-meta with sddm.

When I change the configuration of the monitor to only show the archlinux installation, the screen size just grows. The resolution doesn't get updated.
When I do:

xrandr --output HDMI-0 --mode 3840x1600; xrandr --auto

The monitor turns blank again.

This is my xorg.conf:

EndSection

This is generated by nvidia-xconfig. The

DPMS Disable

I've added manually. But that changes nothing.

Does anyone have any ideas on how to fix this?
