I noticed something today which seems common to the other poster's problem and related. After the F17 upgrade, xrandr throws an error and doesn't detect my displays properly (but my displays still work). There is also an intel module error in the xorg logs.
Code:
[dmace@thinkpad ~]$ grep EE /var/log/Xorg.0.log | grep intel
[ 23.788] (EE) Failed to load module "intel" (module requirement mismatch, 0)
[dmace@thinkpad ~]$ xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 0.0*
Surely this is related. Is there some way to fix the intel driver loading (which I thought was part of the kernel)?
