Long time brightness problem with GL games e.g. openarena
It would be great if the drivers could be tested in gaming scenarios. I've a rather new Dell desktop with "Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)" and I'm running kubuntu 11.10 with the i965 driver.
Desktop effects work fine and I've no complaint with the graphics in most scenarios, but when I play openarena, the screen is very dark and the brightness controls have no effect. Google shows this to be a common problem with gamers using intel graphics, and I haven't seen anything like solution. Needless to say, I've used nvidia graphics cards for gaming and of course the brightness controls work fine in openarena. Is there any hope on the horizon for gamers on intel graphics?

Why should something prevent Oilrush from running? You only need float textures active and s3tc. That game does not require opengl 3.0 at all. If you want to use Unigine engine with TESSELATION you need opengl 4, that could be implemented in theory with ivi bridge. But: tesselation is so slow on lowend chips that you would get a slideshow. When you remember: the first Unigine Heaven releases could use some specific ATI only tesselation engine on older hd 4 cards as well, it worked but was something like 7 fps, i do not expect more from an integrated gfx. Newer Unigine releases did not have got support for that extension, there you need a full opengl 4 card. But oilrush looks so simple, that tesselation will not help at all - for that game you definitely do not need an opengl 4 card.

It is available on Ivy Bridge, yes, so GL 3.x should be supported on that architecture with hardware acceleration. For previous generations (Sandy Bridge and Ironlake), some parts of it must go through software-only implementations.Last edited by Shining Arcanine; 18 January 2012, 06:21 AM.

external graphic card over thunderbolt
I don't know if this needs support from intel, but i would like to know what is needed to get an external graphic card over thunderbolt running in the (remote) future.
If it needs work from intel, is there any plan to support this?
Thanks for your answers.
Greetings.

Here are some Ubuntu users that experience 1 to 4 machine shutdown when rc6 enabled on kernel 3.2 (selected posts) :

Do you happen to know if/when the work of Gwenole whould be included in the upstream mplayer?
However, while we are on topic of VAAPI, I believe the news about VAAPI support for Medfield chips got missed from Phoronix news? It is available at http://cgit.freedesktop.org/vaapi/pvr-driver/, and should support Penwell and Medfield platforms.

When you look at
then the links (for mplayer) are a bit outdated (libva 1.0.15 will be splitted too), also does "Intel? HD Graphics" refer only to s1156 or to the s1155 pentium/celeron as well? Or is it just like 2000/3000 without the encoding parts only?
