[SOLVED] Xorg won't start using nouveau, No devices detected

[lilrc]

I have a major problem getting nouveau to work with xorg. It worked some time ago until I recompiled the kernel using a different config file (sadly, I lost the working one...). I have tried editing the kernel config for some time but I can't get it working. The nouveau kernel driver works except that startx gives me errors. The framebuffer console looks fine and /sys/class/drm seems OK.

I get "(EE) No devices detected" and "no screens found" from the Xorg.0.log. The complete file can be found at: http://pastebin.com/e3Qj2NHg

The dmesg also seems pretty OK.
The complete output: http://pastebin.com/L20XauBT

There is another thread on the forum which handles a similar problem (https://forums.gentoo.org/viewtopic-p-6712339.html) where the solution was adding udev to the correct runlevel. I've added udev to sysinit, but still no luck.

Here's also the output of "lspci", if it could be relevant. http://pastebin.com/DJbzHpa6

The card works with the nv-driver (with nouveau removed from both kernelspace and userspace). The nv-driver however lacks some nice functions, like acceleration. I can also get X started with the VESA-driver.

All help is greatly appreciated

lilrc,

Everything you posted looks good, so the problem must be with something you didn't post.

Can we see your kernel .config file please. The decompressed /proc/config.gz is preferred but if thats not there, the .config that belongs to the kernel shown by

Alright, here is my kernel config, it is from the decompressed /proc/config.gz.

The kernel side of things looks mostly fine, except for this:

Unsetting CONFIG_EXPERT fixed the problem!

Thank you very much for your help!
