Text console on AMDGPU: Select which monitor to use?
The normal text console is currently displayed on all monitors, using the smallest resolution for all of them. Is there a way to change that to only use my main monitor?
The motherboard firmware and GRUB menu are displayed correctly (only on the main monitor). I believe that UEFI GOP graphics are used up until the handoff to Linux. After the "Triggering uevents..." message, the screen briefly flickers and my secondaries activate, which then keep redundantly displaying the same content. This persists if I stay in the console.
Is there some kernel or driver parameter that controls this behavior?

Re: Text console on AMDGPU: Select which monitor to use?
https://raw.githubusercontent.com/torva … modedb.rst
see the video= kernel parameter options and the "d" flag to disable undesired monitors.

Re: Text console on AMDGPU: Select which monitor to use?
I've just tried "video=HDMI-A-1:d video=DP-2:d", which has the desired effect in text mode but also completely disables those monitors system-wide. Is there a different way?

Sure? What does "system-wide" mean?
for OUT in /sys/class/drm/card*; do echo $OUT; edid-decode $OUT/edid; echo "================="; doneYou'll need https://aur.archlinux.org/packages/edid-decode-git

Re: Text console on AMDGPU: Select which monitor to use?
They don't work and don't show up in the KDE settings or with inxi -aG or xrandr. Maybe Wayland tacitly adopts the settings from text mode?
