completely locks up the keyboard with the monitor immediately put into its
low-power state (as close to turned off as possible without quite being
turned off) so the only recourse is to log in remotely and shutdown or to
reset to regain control of the keyboard. Everything worked fine
for previous version (2:2.1.1-4) although there was initially a lot
of trouble with modelines and VGA-1 until I found the right combination
in xorg.conf to get 2:2.1.1-4 to work.
Note, I have tried some other variations such as VGA rather than VGA-1, but
that didn't help the complete lockup with X -probeonly. In the log below
you will see
First SDVO output reported failure to sync
I previously (with 2:2.1.1-4) never saw that error message.
Any advice you could give me to work around the present hard lock
and restore X to normalcy would be much appreciated. For example,
is there any way for me to get back to 2:2.1.1-4?
The 2:2.1.1-4 package is available from:
http://snapshot.debian.net/archive/2007/09/17/debian/pool/main/x/xserver-xorg-video-intel/
Could you also try 2:2.1.99-1 to see if it was broken too?

Here are the results of my tests now. The Debian testing version of xorg
works fine on the graphical chip in my g33 chipset (ASUS P5K-V MB).
xorg.conf uses a gtf-generated 1024x768@85Hz modeline. The Debian unstable
version of xorg using xserver-xorg-video-intel version 2:2.1.1-4 works fine
as well with exactly the same xorg.conf file. If the Debian unstable
version of xorg is kept exactly the same except and "upgrade" of the
xserver-xorg-video-intel package to either 2:2.1.99-1 or 2:2.2.0-1,
X -probeonly
completely locks up (no access to keyboard). So the problem was introduced
between 2:2.1.1-4 and 2:2.1.99-1.
When passing this information to upstream, I suggest you emphasize the
error message "First SDVO output reported failure to sync" since googling for
that phrase indicates it is a fairly rare error message.
It there are any other tests you would like me to do (especially if you
have any newer xserver-xorg-video-intel versions you would like me to try),
I would be glad to help because a clean sid version means Debian testing
will be that much better.
Finally, I suggest you find some temporary means to keep the present
unstable version of xorg from being deployed to Debian testing until this
bug is fixed. I believe g33 chipset owners using Debian testing (which
works right now for me and presumably them) will be severely disappointed if
that precaution is not taken.
