Description:

After updating xorg-server to 1.4.0.90-8, X freezes when I try to quit it an go back to console.
It's a typical X freeze. The picture on the monitor stays the same and no input is accepted.
I had a look at the new patches in the PKGBUILD an tried some stuff and finally came to a conclusion:
The freezes are caused by the xorg-server-1.4-git20080227.patch patch. Commenting it out form the PKGBUILD makes X behave normal again.
I also tried different versions of my video driver and different AccelMethods, but they all didn't change anything.
Therefore it must be the patch which causes the freezes.

Additional info:

xorg-server 1.4.0.90-8
mesa 7.0.3rc2-1
libgl 7.0.3rc2-1
xf86-video-intel 2.2.1-2

Steps to reproduce:

Everything works as normal when:
- xorg-server 1.4.0.90-7 is used
- vanilla (all patches in the PKGBUILD commented out) xorg-server compiled
- only xorg-server-1.4-git20080227.patch commented out, all other left untouched
xorg-server freezes when:
- using xorg-server from extra (no patches commented out)
- all patches but xorg-server-1.4-git20080227.patch commented out
This task depends upon

I can't reproduce this on my systems. Do you use a framebuffer console?

No. I even do not use the parameter vga=... in grub.

Could you supply the Xorg.0.log when this happens (use SSH from a different machine to get into yours if possible), and the xorg.conf you're using?

the same acts on my systems.

on my system, if i quit the first X, or rather, restart X, it will freeze..

xorg-server 1.4.0.90-8
mesa 7.0.3rc2-1
libgl 7.0.3rc2-1
xf86-video-ati 6.8.0-2

and i use a framebuffer console.

Can't ssh into the machine now.
I'll see what I can do.

Does this still happen with the -9 version of xorg-server? I see you have at least one option in your xorg.conf that triggers a crash fixed in -9 of xorg-server. When I was testing yesterday, on the first crash my system worked fine, on the 2nd crash I had a complete lockup and had to reset my computer to get it working again.

Yes, the lockups are gone and OpenOffice.org does its work again.
The only thing that still does not work perfectly is the nvidia-driver. Sometimes it kills Xorg on the reset that is done during logout. But this must be a problem inside this proprietary driver, it started a few months ago. Hopefully the next version will fix this lasting bug.

I just issued a reboot from a terminal within X. X does freeze but the reboot procedure will continue.
I attached the Xorg.0.log I found after the reboot and before starting X again.

Furthermore I found an interesting post on the forum: http://bbs.archlinux.org/viewtopic.php?id=45806
The poster points to a Debian bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=461783
He also notes the switching the XkbModel in xorg.conf from "latitude" to "pc102" solves this issue.
As you can see in my previously attached xorg.conf I also have set XkbModel to "latitude". I switched it to "pc105" and the freezes where history!

So it actually is related, if not the same as  FS#9887 : http://bugs.archlinux.org/task/9887

-9 is out? My mirror must not have synced yet...
I'll try it as soon as I can.

Ok, I installed xorg-server 1.4.0.90-9 a second ago and switched XkbModel back to "latitude".
Everything is working fine again. No freezes on quit anymore.
Thank you.
