I have attached the output from pciconf -lvb, sysctl -a |grep ^hw.dri
reports:
hw.dri.0.name: radeon 0x96
hw.dri.0.vm:
hw.dri.0.clients:
hw.dri.0.vblank:
hw.dri.0.debug: 0
I loaded radeon.ko from within my X session, which was started with DRI
"OFF".
If I run startx with DRI "True" or without an xorg.conf, the
screen goes into standby as if the pc is turned off, the mouse and
keyboard stops responding to keypresses (ie. numlock-led will not
respond to me pressing the key.) and I cannot ssh into the machine. As
far as I can tell it has crashed.
There is nothing in /var/log/messages, which gives any indication
that something went wrong (If I boot the machine - startx and force a
reboot I get 2 x dmesg plus fsck messages).
Xorg.0.log contains only messages from the last successful start of
xorg, and is a far as I can tell useless in tracking this down.
