Description mcope 2007-12-18 11:42:34 UTC 
When starting X using the git radeon driver, X returns to the console and errors and warnings are reported in the log.

The attached xorg.conf worked correctly with the previous release of the driver.

There are some warnings in Xorg.0.log:

The I2C warnings were present in logs using older drivers, but did not result in any obvious problems.

Are you starting the laptop with the lid closed?  It's detecting the lid as closed and hence the driver things there are no screens attached.  If you lid is not closed then your acpi lid information is wrong.

I can no longer recreate this bug.  Whatever the problem was it's gone away now!
