Hello, I recently upgraded a NUC (which is my kodi media server) to bullseye. I always had an issue with the overscan of my TV monitor. The overscan cannot be disabled on the monitor (it is an 16 year old sharp). And I tried to compensate via xrandr --transform, which I never was able to figure out. But you can set in kodi the display to compensate for this. You still can do this, however kodi(bullseye) forgets these settings, which means you have to configure this after every new start of kodi. I think this might be a bug. But now I want o try again to solve the overscan issue on system level (most likely again with xrandr) Now this sytem runs with wayland and for any combination of the --transform matrix I currently get an error: X Error of failed request: BadValue (Integer parameter out of range for operation) the initail try was just xrandr --output XWAYLAND3 --mode 1280x720 --transform 1.05,0,-10,0,1,0,0,0,1 to shift the x axis. Is this a wayland issue? -H -- Henning Follmann | hfollmann@itcfollmann.com

On a 39" Proscan I needed this to eliminate overscan: xrandr --output HDMI-1 --set underscan on --set "underscan vborder" 20 --set "underscan hborder" 35 -- Evolution as taught in public schools is, like religion, based on faith, not based on science.

However that does not work either. It fails with "font or color unknown", which I think ia misleading. I suspect that wayland does not allow me to set any properties with xrandr. -H -- Henning Follmann | hfollmann@itcfollmann.com

I would assume that Wayland's such tools will be named with either wayland-… or gnome-…, rather than x…, to distinguish the two worlds. Cheers, David.
