Bug#417601: x11r6: On startup, X11 reports that my G450 is not DRI capable.

Brice,

Sorry about causing a bit of confusion about my xorg.conf.

The unedited original that worked (but was simple/single-head)
was xorg.conf.good.  The installation did *not* come up as dual-head.

To enable dual-head, I manually edited xorg.conf.  The script you had
me run displayed the *hand-edited* xorg.conf which I currently run.

What would be the easiest/safest way to upgrade to experimental?
My system's kind of limping right now and I need it daily.  I have a
spare 80Gb drive I can enlist if need be.

I'd be happy to upgrade to experimental, but this will take several
steps and some time to accomplish.  One attempt to upgrade from
Stable to Testing made my original Stable disk inop (no X11).  While
trying to restore from my exact backup I encountered a ide error
while running the Testing.  This error wiped out most of my backup,
leaving me two partial disks.  I recovered my personal data, rebuilt
my backup disk with Testing and this is the system I am currently
running (the problem was reported before restoring any personal
data).

Thanks.

Dale

Here it is.  I got some function to DRI now, but
nothing near the performance I had with "Stable".


Which xserver-xorg-core and xserver-xorg-video-mga packages do you have?

Could you try upgrading them to experimental ? (xserver-xorg-core
2:1.2.99.905-3 and xserver-xorg-video-mga 1:1.4.6.1.dfsg.1-1). Note that
if you don't want to upgrade to libc2.5 because of this, you may want to
take an earlier xserver-xorg-core from
http://snapshot.debian.net/archive/2007/04/10/debian/pool/main/x/xorg-server/


So far the problems with Testing seem to all but
minute, but there are a lot of them.  I just had
iceape -mail to a segment abort after composing
a fairly length e-mail....


Do you have a way to reproduce such a crash? It would be helpful to get
a backtrace with gdb.

This xorg.conf is far from simple. You seem to have removed dualhead and
nohal from the "good" xorg.conf, right? And it helped a lot? Any idea
whether dualhead made the biggest difference?


(**) MGA(0): "off" is not a valid value for Option "Rotate"


You should drop your rotate option :)


(EE) MGA(1): Not initializing the DRI on the second head


Do you get DRI on the first head?
