Xorg.0.log

This problem is independent of the system CPU load and 100% reproducible
on my Thinkpad X301 (Intel X4500 graphics hardware).

The server exists clean and there is no crash or apparent failure in
the Xorg.0.log. There is no more X server running and all X applications
have terminated. I have checked this with ps -auxw
They all exit quickly and normally. The cpu load is near to zero.

However the server (or probably the xf86-video-intel driver) fails 
to restore the console.

I can still remotely log into the machine and shut it down clean but
the console is not usable. The screen is just black and the
backlight is still on.

I am myself a bit puzzled by this problem and I am happy to provide
any additional printouts.

The system is gentoo with:
 
ACCEPT_KEYWORDS=~x86 emerge -pv =x11-base/xorg-server-1.6.2-r1
ACCEPT_KEYWORDS=~x86 emerge -pv =x11-drivers/xf86-video-intel-2.7.1
ACCEPT_KEYWORDS=~x86 emerge -pv =x11-drivers/xf86-input-keyboard-1.3.2
ACCEPT_KEYWORDS=~x86 emerge -pv =x11-drivers/xf86-input-mouse-1.4.0

Attached is an Xorg.0.log take after the X server has already terminated
and the console is in this un-usable state.

I will also attached my xorg.conf file.

Related to this problem might also be that I can not use
crtl-alt-backspace
to switch to the console while X is running. It results in a
frozen screen where the image is still there but the pixels seem 
not so smooth.

I found now a work around for this problem. If I compile the linux
kernel with a frame buffer console then the problem does not appear.

I still think that this is a fault.
Comment 3 Gordon Jin 2009-07-16 18:59:38 UTC
this configuration has been decided as wontfix. See details in bug#22040.

*** This bug has been marked as a duplicate of bug 22040 ***
Comment 4 Guido Socher 2009-07-16 21:03:03 UTC
If you do not plan to fix this fault then you should document
this requirement in the installation instruction.

There is not a single word saying that intel requires a frame buffer console.
It is also quite unexpected because most other drivers do not have such
a behavior.
Comment 5 Jesse Barnes 2009-07-17 09:41:31 UTC
Actually, newer kernels will automatically select framebuffer console for you, so this could me marked fixed.
