Description Sergey Samokhin 2010-08-17 06:11:08 UTC 
"sudo Xorg -configure" fails on my ThinkPad T510 with error:

(EE) intel(0): No kernel modesetting driver detected.

So I cannot generate working xorg.conf for further tuning. Although, Xorg works just fine without config file, I think that "Xorg -configure" should work also.

It's strange, because i915 module is loaded.

I tried to regenerate initramfs with intel_agp and i915 modules included (http://wiki.archlinux.org/index.php/Intel), but it didn't help

KMS is enabled in my kernel by default and working.

Environment:

archlinux i686 current
xorg-server 1.8.1.902
xf86-video-intel 2.12.0
intel-dri 7.8.2
kernel26 2.6.34.3

Attached files:

* Detailed output of "sudo Xorg -configure" is in xorg_configure.txt
* i915 module has been loaded before "Xorg -configure" (see lsmod_grep_i915.txt)
* "sudo lspci -vv -nn" output is in lspci_vv_nn.txt
* Log of running Xorg (without xorg.conf) is in Xorg.0.log
* Parameters passed to my kernel is in menu.lst
* kernel info is in uname_a.txt

    Open-code DRICreatePCIBusID()
    
    During -configure we would attempt to query the availablility of KMS
    before the DRI module was loaded, thus we were unable to create a valid
    bus identifier and so the query failed and we disowned the device.
