Summary: dri doesn't work on second head (r128)
Product: Mesa
Version: CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/r128
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
I run AMD64 Ubuntu Edgy (xorg 7.1) on an Intel DG965WH mobo (g965 graphics)
with a 16MB PCI r128 AIW. I have mesa, drm (user and kernel), and
xf86-video-intel compile from the git sources (as of today, Feb 28, 2007).
In a multihead non-Xinerama (:0.0 is i965, :0.1 is r128) dri is broken on the
second head.

This happens with Ubuntu's stock mesa/dri, too (LD_LIBRARY_PATH=/usr/lib
LIBGL_DRIVERS_PATH=/usr/lib/dri). Same output.

Is the dri parser code broken on screen != 0? I started to look at it, and I
don't see why an option has to be in the cache just because it was requested.
Maybe the cache is supposed to be filled with the defaults first... If so,
that probably didn't happen for the second head.
I'll attach my xorg.conf and my X log.
Running X on either the i965 or r128 head with a single screen on a single
display works fine (xv, glx/dri, xrandr, etc. are all ok). This is also the
case in multiseat mode (2 kbds with evdev input driver, and X -sharevts, two
separate DISPLAYs). Both cards can be running glxgears at the same time. Very
useful for running a web browser + a full screen keyboard-grabbing game.
