Description Ondrej Zary 2008-05-27 07:25:00 UTC

Machine has one PCI-E X1650Pro card and one PCI Radeon 7000. When using only one card, it works. But running second instance of the X server (with different layout that uses the second card), the primary VGA output hangs and the first X server consumes 100% CPU time. It does the same thing both ways (either X1650Pro or Radeon 7000 started first). Even tried running X1650Pro with radeonhd driver and 7000 with radeon driver - it does the same thing. Disabling DRI or VGAAccess does not seem to help.

this should be fixed in 965a5dbcd9dc4bf1cdd7f2bbdec15e9733b2e090 at least with libpciaccess.

Great. I'd like to test it but I'm unable to compile the driver properly in Debian because of dependencies.

Comment 3 Brice Goglin 2008-05-28 03:10:56 UTC

Ondrej,
I just uploaded a new snapshot into debian experimental:
  xserver-xorg-video-ati 6.8.1~git20080528.faea0088-1
It will be in incoming very soon and in unstable tomorrow (for i386 first).

It does not use libpciaccess since it's built against Xserver 1.4 for unstable, but it contains Alex' fix.

Comment 4 Ondrej Zary 2008-05-28 05:06:18 UTC

Thank you, I tested the driver from incoming.

Now I can run both X1650Pro cards with radeonhd driver and Radeon 7000 in second X server with radeon driver. But when running X1650Pro cards with radeon, starting the second X server freezes the first one.

That's bug 16035.  I think we can close this one.
