Bug 372715 – Starting Xorg Freezes the kernel

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Philippe SCHELTE 2011-06-23 21:10:17 UTC]

on a Clevo laptop W251HU with intel i5-2410M and 0116 (rev 09) Graphic device using the i915 driver when Xorg starts the kernel hangs, I must do a hard reboot. No logs are generated.
I have tested with thoose kernels :
- 2.6.38-gentto-r6
- 2.6.39-gentoo-r1
same issue.

It is a Gentoo specific issue because on the same laptop Xorg is working well under XUbuntu and Arch Linux (installed and tested) 

Reproducible: Always

Could You post your kernel config.

try running:
startx > ~/xorg.log
is the xorg.log file created in you home directory?

what version of xorg and the intel display driver are you running? what version does ubuntu/arch use?

Can you try installing an ubuntu or arch kernel into gentoo, does that help?

Created attachment 278025 [details]
the 2.6.38-gentoo-r6 config

I had the same problem. Solved it by reemerge all xorg drivers as sugested by emerge.


WARN: postinst
You must rebuild all drivers if upgrading from <xorg-server-1.10
because the ABI changed. If you cannot start X because
of module version mismatch errors, this is your problem.
You can generate a list of all installed packages in the x11-drivers
category using this command:
	emerge portage-utils; qlist -I -C x11-drivers/
or using sets from portage-2.2:
	emerge @x11-module-rebuild

The xorg.log is created but empty (page blank)

xorg version : 1.9.5
xf86-video-intel : 2.14.0

on XUbuntu 

xorg version : 1:7.6+4ubuntu3 (cryptic for me hope you will be able to compare)
xserver-xorg-video-intel : 2:2.14.0-4ubuntu7.14 (seems to be the same)

same issue when I use an Ubuntu kernel into my Gentoo install.

Something different I have noticed when I boot on Ubuntu and Gentoo is that :

>> Booting (initramfs)>> ERROR: your real /dev is missing files required to boot (console and null)..

althought after loging :

# ls -al /dev/console /dev/null
crw-rw---- 1 root root 5, 1 jun 24 19:32 /dev/console
crw-rw---- 1 root root 1, 3 jun 24 19:32 /dev/null

Thanks !

I have followed the houmles advice, emerging world => same issue
I have put x11-base/xorg-server ~amd64 in /etc/portage/package.keywords
and emerging xorg-server (1.10.2) re-emerging xf86-video-intel => same issue
