Title:
[amdgpu] Proper monitor resolution/refresh rate not available
Status in linux package in Ubuntu:
Confirmed
Status in xserver-xorg-video-amdgpu package in Ubuntu:
New
Bug description:
I'm currently (in Ubuntu 20.04) stuck with this low resolution: 640x480
59.94*, what I want to have is the monitor specs: 1080p and 144 Hz. This
problem appeared after plugging in my old monitor after 2 years again, it's a
philips 272G5DYEB. Things that I unsuccesfully tried to get a proper
resolution:
-Use different GPUs from different vendors: 1050 ti and 5700 xt. Use
different drivers: propritary and open source
-Change resolution via xrandr addmode/newmode (leads to "no signal" from
monitor)
-Using "GRUB_GFXMODE" config in grub (no change)
-Searching through logs, only useleful thing I found was in the Xorg log:
[ 12.117] (II) AMDGPU(0): EDID for output DisplayPort-0
[ 12.117] (II) AMDGPU(0): Printing probed modes for output DisplayPort-0
[ 12.117] (II) AMDGPU(0): Modeline "640x480"x59.9 25.18 640 656 752 800
480 490 492 525 -hsync -vsync (31.5 kHz e)
-In Windows the resolution works fine
-Both GPUs work fine with a different monitor
I'm not sure how to proceed here nor do I know where the problem lies. I
assume this to be a bug in Ubuntu because a bunch of different GPUs/drivers
lead to this problem making it unlikely to be a driver problem.
