I found that `find /sys | grep edid$ | xargs file -i` will always report the file is empty.
Please use `find /sys | grep edid$ | xargs cat` to find out which one is non-empty and attach the EDID here. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1879402 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.
