Hi all,

I have been running etch for a while without problems. But suddenly
my xorg doesn't work. I have a backup of working xorg.conf but it
doesn't work now. I remember I have an update days ago including
xorg. I'm not sure if that is the problem. I also ran
dpkg-reconfigure xserver-xorg again but with no luck. I used my old
xorg.conf file with the following /var/log/Xorg.0.log

What an excellent question. First one I've seen in a while.

Here is your problem.

My xorg.conf is

Section "Files"

Some these (the ones pointing to /usr/X11R6) should be removed as your
xorg was saying they don't exist.

You also have more than one definition for your i810, and I suspect that
you may need to reload the 810 drivers for the kernel. I'm not that
familiar with the intel graphics, so I could be wrong on that account,
but I do see that you have multiple entries for that device. Hopefully
this will help. Note that dpkg-reconfigure will handle one screen, but
not two, so your duel head must be configured manually. See comments above.

It looks to me like your duel head configuration is a bit off. I don't
think you put the screen definition in the device itself, but rather in
the serverlayout, but then again, how does one differentiate between one
head or the other on a duel head card?

I'm sure someone else will comment about this, and point out how much of
a bloody idiot I am in trying to help you in the first place.

Good luck.
