Bug#494610: Server hangs on startup when using a custom mode
Package: xserver-xorg-video-intel
Version: 2.2.1-1~etchnhalf2
Other possibly relevant package versions:
xserver-xorg-core 2:1.1.1-21etch5
linux-image-2.6.24-etchnhalf.1-686 2.6.24-6~etchnhalf.4
Video chipset: Intel G33
When etchnhalf was released, I switched from testing's X server
(xserver-xorg-video-intel and xserver-xorg-core) to etchnhalf. My
/etc/X11/xorg.conf contained, among others, the following lines in the
Monitor section:
Modeline "1600x1200" 185.75 1600 1664 1856 2160 1200 1201 1204 1241
Option "PreferredMode" "1600x1200"
With testing's packages, there was no problem, and I had a 1600x1200, 69 Hz
mode. With etchnhalf, the server hangs on startup: the screen becomes
blank, I cannot switch to a text console with Ctrl-Alt-Fn, and
Ctrl-Alt-Backspace does not do anything visible. However, Ctrl-Alt-Suppr
works, and it seems to be the only thing I can do.
The log ends with

When commenting the line "PreferredMode" in xorg.conf, the server starts
up normally in 1152x864 mode, and then I can switch to my 1600x1200 mode
(the one defined by the Modeline) with `xrandr -s 1600x1200'.
Here's the diff -u of xorg.conf with the PreferredMode option (and the
hangup) and without:

that is, the log without the PreferredMode option contains the full content
of the log with the PreferredMode option, and then continues with the
setting of the video mode and various stuff.
When uncommenting the PreferredMode option and commenting the Modeline,
the server starts up normally, with the standard 1600x1200, 60 Hz mode.
Regards.
