LinuxCNC 2.9.2 Raspberry pi 5 cannot hange resolution

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 !

 

This is really annoying ! Can anyone help me pretty please ?

The image you find in this link has no problems with the video driver

forum.linuxcnc.org/9-installing-linuxcnc...pi-5?start=60#287616

When i download the image and extract it i get error, third attempt.

 

The pi5 image from the site is the one with video driver problems.

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.

 


 

Thank you so much it worked ! I used :
7zz x image_pi5_rt.zip
command in Ubuntu terminal to extract
