The good news is that KMS now works, the bad news is KDM still wont
start with compositing. Plain X works and glxgears work as does KDM
with compositing off
Glxgears says:
IRQ's not enabled, falling back to busy waits: 2 1
do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
My dmesg says:
Unpin not necessary for ffff88007c9a1600 !
Unpin not necessary for ffff88006eda6400 !
Unpin not necessary for ffff88006b14d400 !
I couldn't see anything in my Xorg.0.log file that would explain why
KDM keeps rebooting
Is there anything else that might be useful?
