Comment 13 for bug 63051

There is no fix. It is a workaround, and it's posted a few comments up. The default "Accelmethod" of EXA in the xorg.conf causes the trident driver to break, you must replace the "Accelmethod" with XAA. I also download the EXPERIMENTAL or UNSTABLE trident driver from the Debian repositories and then I unpack the deb, and copy the trident_drv.so over the default one, just for good measure. I sent Mark a step by step workaround. Here is the email:

Try this:

I'm including two files, one is my xorg.conf file, and the other is
the experimental trident driver. Download both of these to a suitable
location, then execute the following commands in a terminal in order:

cd <to the directory you downloaded to>
sudo cp /usr/lib/xorg/modules/drivers/trident_drv.so
/usr/lib/xorg/modules/drivers/trident.old
sudo cp ./trident_drv.so /usr/lib/xorg/modules/drivers/trident_drv.so
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
sudo cp ./xorg.conf /etc/X11/xorg.conf
xinit

Let me know if it works for you.

The file was just the trident_drv.so that I unpacked from the xserver-xorg-video-trident driver from the Debian repoisitory. You can get the BINARY from here :

http://packages.debian.org/cgi-bin/download.pl?arch=i386&file=pool%2Fmain%2Fx%2Fxserver-xorg-video-trident%2Fxserver-xorg-video-trident_1.2.3-1_i386.deb&md5sum=ca10e27dd0595cf9024adf53145d671a&arch=i386&type=main

YOU MUST NOT ATTEMPT TO INSTALL THIS FILE. YOU MUST UNPACK THIS FILE AND MANUALLY COPY THE TRIDENT_DRV.SO FILE OR YOU WILL BREAK YOUR XORG CONFIG. To unpack the xserver-xorg-video-trident driver file, you must 'ar -x xserver-xorg-video-trident.deb' This will yield two tar.gz files. Inside of one of these files is the trident_drv.so file you need.

The xorg.conf file is just a vanilla xorg.conf file with the aforementioned changes.
