xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1280 x 1024, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024     60.00* 

Hello!!!

I always have have this habit to apply the “75.02 refresh rate” my monitor supports.

But, somehow, xrandr disagrees at the moment. What should I do?

then post post the inxi command output so that prospective helpful souls will know which video card and driver are in use on your system.

I found numerous similar topics but failed to detect the problem’s cause. Sorry for causing that forum burnout to you

I had to reinstall OS.

Here is the output before launching “antix updater”

It seems “fbdev” “llvmpipe” are the culprit

Also an update during “antix updater” maybe the cause
