Description: When using any 3D accelerator, it seems that OpenGL 2.0 features are not shown correctly. My chip, Mobile Intel GM45, is said to have OpenGL 2.0 capable but most OpenGL 2.0 features do not show correctly. UXA and EXA Accelerating methods do not show a difference in the problem (while nomodeset as a kernel argument and shown in log) while XAA actually prevent X from starting (not there?). I found that turning NoAccel option in xorg.conf (or using a software renderer) works but is slow (of course) and using OpenGL features only still work correctly. 

Version-Release number of selected component: xorg-x11-drv-intel-2.7.0-7.fc11.i586

How reproducible: There seems to be a couple of people having these problems with different cards. Using any shaders with OpenGL will not work and you will get a static-like image.

Additional info: This problem does not exist on other Linux distributions. I've used Gentoo for a year or two with much better support and OpenSUSE (although I hated OpenSUSE for random crashing with what seems to be no error) also had no problems displaying the wanted graphics. 

Also, the recent update of the Intel driver actually fixed a major problem I had. Before single buffered windows would not work at all and were very distorted. It seems major bugs are fixed every release and my belief is that the latest drivers (2.8.1) would be able to fix this. I'm not 100% sure though.

Screenshot Example

Please note that the square in the middle is in the position where it's supposed to be since in the example the square is moving. The distortions such as the uneven box and static-like picture is the pin-pointed problems.

Xorg.0.log (current non-working log)

The following shows most of the configuration of the Xorg server. Remember I've already tried XAA and EXA with no change from UXA.

I never even knew the Smolt profile existed before this lol.

The xorg.conf I think is irrelevant. It works without and with the configuration and the tiling option also had no affect whatsoever.

The sentence, "using OpenGL
features only still work correctly." is meant be "using OpenGL less than 1.3 features only still work correctly."

Comment 9 Zachary 2009-09-30 00:37:41 UTC
I've found that moving to Fedora 12 Pre-release milestone has fixed ALL of the problems described above. I've yet to find any problem with rendering the correct graphics and features.

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command

yum upgrade --enablerepo='*-updates-testing'

Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD .

Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.

If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.

Zachary, do you mean (in Comment #9) that this is no longer an issue? (Just checking before closing.)

Comment 13 Zachary 2010-04-15 00:56:03 UTC
I fail to see how its insufficeient data as I've already mentioned that the bugs are mainly fixed in the later version because of update Intel drivers.

However, there are still problems. Intel Linux drivers are heavily in development and will be for a good while now. Intel isn't the way to go on Linux graphics. For now, I'm rooting for the guys over at http://intellinuxgraphics.org
