Bug#463076: xserver-xorg-video-ati: machine freezes when X is stopped or second X started

[Roger Leigh]

Hi folks,

Just another datapoint for this bug.  My Mac Mini has a

0000:00:10.0 VGA compatible controller: ATI Technologies Inc RV280
[Radeon 9200] (rev 01) (prog-if 00 [VGA controller])

and I was also bitten by this bug.  My system locked hard if I tried to
kill X or shutdown the system (which causes kdm to stop X).  It also
locked if I tried to switch to a VT with C-A-Fn.

Further investigation showed that this worked perfectly if I booted the
system with "video=radeonfb:1680x1050-32 at 60" on the command-line.  I can
now switch VTs at will, as well as start and stop X, shut down the
system, etc. without problems.

However, booting with "video=ofonly" results in all the problems
mentioned above.


Is this the same for the other people suffering from this bug?

It might be an issue with the OF framebuffer, or the attempt to restore
the framebuffer when X terminates or VT switches.  IME, ofonly doesn't
come back when you end X, but previously you just got a black screen
rather than a lockup.


Regards,
Roger
