How to debug Xorg startaup hangs (ATI Radeon 9550)

Hello,


I'm a bit frustrated, because X often hangs on startup - not every
time, but nearly half of the time. I've tried various combinations of
16bit/24bit color depth, dri enabled/disabled.

X startup looks like the following on my system: my LCD goes black,
and shows "digital" - it detects a signal at the digital input port.
Then a few seconds pass, and if I'm lucky, "digital" appears again and
then the desktop. If I have bad look, it doesn't...

I have Fedora Core 6 - but the problem has been around for a long
time, also in Fedora Core 5. I have a Radeon 9550 card, detected as
"Chipset ATI Radeon 9600 AS (AGP)".

I would really like to help debug this problem - please tell me how.


regards, Stefan
