Default glxgears @ 1FPS!

(moved from another thread)

Hi,
I'm depressed to read that folks think 300 FPS is poor, anything would be an improvement on 1FPS!

I've included information from the logs etc but I can't find any errors. DRI appears to be loaded so I've no idea why the low frame rate.

Messing about I changed the permissions on /dev/drm0 from
crw-rw---- to crw------- and performance improves.

sudo chmod g-rw /dev/drm0
$ glxgears
481 frames in 5.0 seconds = 95.993 FPS
479 frames in 5.0 seconds = 95.743 FPS
478 frames in 5.0 seconds = 95.471 FPS
481 frames in 5.0 seconds = 96.019 FPS

then change it back.
sudo chmod g+rw /dev/drm0
$ glxgears
9 frames in 6.0 seconds = 1.496 FPS
8 frames in 6.0 seconds = 1.333 FPS
7 frames in 6.0 seconds = 1.167 FPS


Information from logs etc
uname -a
OpenBSD hobnob.home 5.3 GENERIC.MP#62 amd64


glxinfo |grep renderer
OpenGL renderer string: Mesa DRI R600 (RV630 9581) TCL

dmesg | grep vga

wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation)
radeondrm0 at vga1: apic 1 int 16

and from Xorg log.

Any help appreciated.
