I have downloaded LinuxCNC 2.9.2 for pi4 and pi5. Pi4 works perfect so far,but on the pi 5 i cannot change display resolution it is stuck on 1920x1080 i have tried to edit profile , xrandr but get gamma error if i change config.txt it only works before loading xfce4 then 1920x1080. I also downloaded image again just to be sure. I have alse tried to google a solution , no luck !

I checked.
he file must be decompressed with 7zip (www.7-zip.org/) and the image can be written to SD with Balena Etcher (etcher.balena.io/).

As you can see from the photo, LinuCNC works and you can select the screen resolution.
