xorg.conf

I've got a Gigabyte Radeon 3870 card with two digital LCD screen connected via DVI-D.  I'm using the radeonhd driver from debian sid (version 1.2.5-1), and although the initialization of the card seem to go fine, I don't get any output (just a black screen, no mouse cursor, no corruption, monitor stays on).  I'm still able to switch back to the console with crtl-alt-f1 and to kill the X server with ctrl-alt-bs, so X is definitely running;  it just seems I get no output.

I've tried various combination of turning off Xrandr, DRI, turning on UseAtomBIOS, and changing the AccellMethod and HPD setting, but it doesn't make any difference.

Was this working with an older version of the driver?

How do you start X for testing? Its default is to only show a black screen nowadays - try "X -retro" for the old behavior.

Ok, never mind.  Turns out the old default background pattern of a clean X was removed in the latest Debian package of Xorg.  Everything is working fine.

Sorry for the noise.
