Description of problem:
Machine Dell Latitude D410
Using the i810 driver the log Xorg.0.log shows
(II) I810(0): [DRI] installation complete
(II) I810(0): direct rendering: Enabled
however glxinfo shows "direct rendering: No"
and graphics acceleration is not working.
Full xorg.conf and log are here:
Searching the web, this seems to be a problem with recent kernels in some distributions when using the i810/i915 drivers.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.use recommended i810 driver with Intel i915GM graphics
3.log shows dri enabled but it is not enabled
Actual Results: log shows dri enabled but it is not enabled and graphics is slow: not accelerated.
Expected Results: Graphics should be accelerated (reportedly OK with some older kernels, but I have not checked).
can you try the kernel from http://people.redhat.com/davej/kernels/Fedora/FC4 ,
and attach a dmesg -s 128000 output please ?
No change with kernel-2.6.14-1.1775_FC4.i686.rpm. But Alan Hourihane says this

Apparantly later X.Org has support, so it is probably fixed in Rawhide, but yum
throws up too many dependency issues when I try to upgrade to rawhide's
xorg-x11, so I havn't tried that.
