Description Walter Neumann 2005-12-22 06:20:59 UTC

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):
kernel-2.6.14-1.1653_FC4

How reproducible:
Always

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 
http://lists.freedesktop.org/archives/xorg/2005-December/011822.html

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.
