Bug Description

Binary package hint: xserver-xorg-video-intel

I have a i965 (X3100) running under Ubuntu Gutsy with the xserver-xorg-video-intel-2.1.1-0ubuntu9 driver. It is set up in BIOS to use 256MB VRAM.

When using some 3D apps with DRI enabled, some surfaces are not rendered (especially if they use vertex or fragment shaders - of any version) - instead they are black (or the whole scene is black). This is reproducible in all OGRE samples and also Mafia running under Wine (and probably some other 3D programs running under Wine). It does not occur in any of the 3D Screensavers, Scorched3D or PlanetPenguin Racer.

When DRI is disabled, the OGRE samples render correctly (for the most part) but run incredibly slowly (i.e. 2fps).

This bug occurs both with and without Compiz enabled, and is not experienced using ATI or nVidia cards with proprietary drivers. Consequently, I think its a bug in this package (or possibly mesa?).

Edit: This bug is also apparent in FooBillard (the tabletop is black!)

Please attach your /etc/X11/xorg.conf, /var/log/Xorg.0.log, and the output from lspci -vvnn.

Also, please test this against Hardy alpha2 or newer, which has the -intel 2.2 driver, to verify the issue still exists with the latest code.

Unfortunately, I can't test this against Hardy as I don't have the bandwidth to download it. I did try compiling the 2.2 drivers from source under Gutsy, together with Mesa 7.1. This partially fixed the problem, although its starting to look like Mesa may be the culprit. Textures were rendered correctly in Mafia and Foobillard with this combination but OGRE and Blender failed to start due to failure to load some GL extentions - that sounds like Mesa's fault.

On hardy, FooBillard seems to still have some texture issues -- the table looks pure black to me, except for the green logo in the middle.

TuxRacer runs at 3fps for me with my ThinkPad X61T with an Intel X3100 card.

If I try to run 3d applications in WINE the entire X Session just restarts.
