Hi, after the upgrade to X server 21.1.1, some people reported crashes in the radeon driver when using xrandr(1) or a similar utility.
If you are seeing these crashes, please test the patch below (copied for a similar "fix" in the amdgpu(4) driver) get the xenocara sources if you don't alreaady, apply the patch in the driver/xf86-video-ati directory and there run (as root) make -f Makefile.bsd-wrapper obj make -f Makefile.bsd-wrapper build Then restart xenodm and try the xrandr invocation again. Please report success or failure.
