Some drivers don't start in Xorg 7.4 on LFS 6.3 with installed Xorg 6.9

I've installed my LFS about a year ago, then Xorg 6.9 from BLFS to /usr. Everything was ok there. Now i decided to upgrade in order to experiment with my i915 chipset. I installed Xorg 7.4 (development BLFS) in /opt/Xorg-7.4. It worked with add-on nv8800gt using nv driver, but when i removed nvidia card to use intel and changed Driver option in xorg.conf to "intel", xorg says "No devices detected". I tried using "vesa" driver, it outputs the same. But "fbdev" does work. What might be the reason?

This is xorg.0.log with fbdev:

with intel (default when no driver is chosen):

with vesa:

And xorg.conf:

Edit: I found it!.. i tried different ways of tracing and debugging just to find out my xorg.conf contained one wrong line... BusID from nv configuration which is different for intel card.

Thumbs up

Great use of a pastebin to reduce clutter in your post.

Also, thanks for posting the solution. That's the LQ spirit.

A suggestion for the future: If you answer your own question, put the solution in a separate post; this does 2 good things:
  • It generates e-mail to anyone who subscribed to either the thread or the forum.
  • It avoids the creation of oxymoronic 0-reply solved threads.
