Bug#1040346: linux-image-6.3.0-2-amd64: AMDGPU only with unusable high resolution available
Update: At least, it works by scaling with xrandr. (--scale 0.5) But it let wdm still unreadable. Regards Klaus -- Klaus Ethgen http://www.ethgen.ch/ pub 4096R/4E20AF1C 2011-05-16Klaus Ethgen Fingerprint: 85D4 CA42 952C 949B 1753 62B3 79D0 B06F 4E20 AF1C signature.asc Description: PGP signature

If you try to > change the resolution to a non-native one, everything gets mushy. No, I don't want the full resolution. It is unreadable. I usually use 1920x1200 which is exactly 1/4 of the resolution so nothing gets mushy. More over, I need to use scaled resolution when using external monitor or beamer that cannot handle 3840x2400. > A lot of technical information about that can be for example found here: > https://wiki.archlinux.org/title/HiDPI Well, that might work with gnome but not with fvwm as it is not native in X. The only native solution is to use a different resolution. See also the attached xorg log from the version before where you have a bunch of native supported resolutions. One is 1920x1200. > > See attached xorg log. > > What happens if you remove the minimally maintained xorg from the > equation and use wayland as output driver, which supports more modern > graphics features? I never got wayland to work. It seems to be always broken when you use something different than gnome. It also does not clearly support network protocol.

But this is what you want, you want to use the full resolution of the output and scale the output (this is called HiDPI). If you try to change the resolution to a non-native one, everything gets mushy. A lot of technical information about that can be for example found here: https://wiki.archlinux.org/title/HiDPI > See attached xorg log. What happens if you remove the minimally maintained xorg from the equation and use wayland as output driver, which supports more modern graphics features?

Package: linux-image-6.3.0-2-amd64 Version: 6.3.11-1 Severity: important With this update of linux-image, there is only the highest resolution available anymore. As this is 3840x2400, it leaves the screen completely unreadable and unusable. Installing the previous kernel solves the problem. See attached xorg log. Note that the error is on a different system where I don't have mail so no additional info attached.
