dmesg with debug enabled.

oops forgot some stuff.
Distro: gentoo
Display: lvds
server version: xorg-server-1.5.3-r5
mesa: 7.4
libdrm: 2.4.5


I cannot get a gdb bug trace, i tried the methods listed in your wiki here:
http://www.x.org/wiki/Development/Documentation/ServerDebugging

but the server dies before it can attach resulting in it erroring out.

Can you try starting w/o an xorg.conf (just rename it or something)?

Also, to get a backtrace you could start the server under gdb instead of trying to attach to it after start, or add a "sleep(3);" somewhere to xf86-video-intel's preinit function to give you time to attach.

i am not familiar with gdb, how do you start a program from within it?

Something like:
  # gdb /usr/bin/Xorg
  ...
  (gdb) run -verbose
should start up the server and land you back in gdb when it exits or crashes.

dmesg without xorg conf.

i tried it without the xorg.conf and end with the same result.

this is what i get when running the debuger.

the driver is compiled for the running xorg server.

Sounds like you built against a libdrm with mode setting support, but aren't running against it, since drmCheckModesettingSupported is in libdrm.

yea kernel 2.6.29 has it but my wireless driver doesn't work on 2.6.29 at the moment so i am stuck on 2.6.28, it loads but refuses to talk to my router which it did on the standard ralink drivers before they were put in the kernel. 

the libdrm i have is marked stable on gentoo and was pulled in with the rest of xorg-server 1.5.3 when that was marked stable.

Could you try rebuilding your intel driver? What Jesse is saying is that you may have built it against a different version of libdrm than you currently have installed.

thats the thing. every time i have to work on debugging this i compile the latest stable driver in the portage tree 2.6.3-r1 to get the information and then when i am done i rebuild the 2.5.1-r1.

I recompiled libdrm, xorg-server, and all my drivers and it's still doing it.

Meh, sorry for the bug spam.

Can you attach a more recent X log (be sure to set its mime type to text/plain)?  The first log looks like maybe libpciaccess is hanging, while the second looks like a libdrm or LD_LIBRARY_PATH problem.  I'm pretty sure other Gentoo users have working configs with this chipset, so I'm still suspecting a config issue here...

Marking as NOTOURBUG on Rémi's advice since this sounds like this should be filed at Gentoo's bugzilla.
