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: http://math.columbia.edu/~neumann/xorg.conf http://math.columbia.edu/~neumann/Xorg.0.log 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). Additional info:
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.
