Re: X won't start: radeon

Hello Michael !

I have also a similar Radeon (HD 3600) - unfortunately crossing fingers does not help enough for me.

Currently the Radeon HD3600
01:00.0 VGA compatible controller: ATI Technologies Inc Mobilitiy Radeon HD 3600 Series 01:00.1 Audio device: ATI Technologies Inc RV635 Audio device [Radeon HD 3600 Series]

does not seem to work at all with the new X-server/libpciaccess.

Reverting back to an older X version makes things work again.

Best regards,

I saw another thread that described the need for

No, that option no longer exists:

Got it -- but any guesses on what I should try?

You could show us your Xorg.0.log for starters.
( it still works on my U60 with a radeon as 2nd head )

Sorry -- I should have said there appeared to be nothing of interest in it. Anyway -- the log from trying to use -configure is in . If I fire up X after removing the xorg.conf file, it doesn't get that error, but it never displays anything and eventually exits. That log is at . I'm running a GENERIC kernel.

Looks like it's one of those radeons that appear as two devices. Also, Xorg -configure doesn't seem to know about PCI domain numbers ( notice the @1 in the PCI identifier in the 2nd log? )
I don't really know why exactly this one fails but what you can try is:
- - use your old config
- - replace the PCI bus identifier in the Device section with "PCI:01@01:00:0"
- - cross fingers

There was talk on the xorg-devel list recently about removing Xorg -configure completely because it doesn't always generate usable config files, the general consensus seemed to be to fix it though, so it would generate the same config as what Xorg would use without a config file. As a short term fix I'll look at the code and see if I can teach it to output PCI identifiers with domain numbers. We'll need that anyway.

have fun
