Linux MESA-LOADER missing device information

[daeron]

After a weekend ports update, the linux-brave browser is now core dumping a bit after complaining "MESA-LOADER: failed to retrieve device information".
I've rebuilt mesa and linux-rl9 ports to no avail, suggestions would be welcomed.

daeron can you confirm that the freebsd drm driver (amdgpu, radeon, i915kms or nvidia) started fine and you are not running a non accelerated desktop?

How to figure out:

• check dmesg or X log for error
• use drm_info (# pkg install drm_info && drm_info | grep Driver)
• glxinfo -B (# pkg install mesa-demos && glxinfo -B | grep Device )

Ta,
Looks ok, and glclock's running happily.
