Description Walter Neumann 2005-12-22 01:20:59 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051201 Fedora/1.5-1.1.fc4.nr Firefox/1.5

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):

How reproducible:

Steps to Reproduce:
1.use recommended i810 driver with Intel i915GM graphics 
2.enable dri
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
is not a bug, it is simply that X.Org 6.8.2 doesn't have any DRI support for the
i915GM. See 

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.
