[Bug 269509] Re: white screen on second session with compiz: pretends to have a second DRI capable head where it doesn't

[Bryce Harrington]

Hi Pitti,

The 'software acceleration only on second head' is a pretty well known
issue and probably not worth reporting upstream since I'm sure they know
about it already.  However, if you're seeing it report 'software
rasterizer' on the first head too, that does seem to be a legitimate
bug.  But I have some follow up questions...

First, can you reproduce this when booted into a single session?  I.e.
does it always show software rasterizer, or only when you have the guest
session going?  I tried reproducing it on my 965 box but couldn't, would
you mind listing the exact steps to reproduce it?

Second, could you attach your Xorg.0.log and Xorg.20.log taken from when
both sessions are up; upstream usually wants that.

Third, you mentioned that glxinfo reports 65 fps... did you mean
glxgears?  65 seems like a pretty low framerate.  Do you recall or could
you test what you get when running the Intrepid LiveCD where the primary
session is not showing up as software rasterizer?

Thanks ahead of time
