Bug Description
I'm using a couple of computers based on Intel DQ35JO board, which has a GMA graphics chip:
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82Q35 Express Integrated Graphics Controller (rev 02)
Running any sort of 3D graphics is incredibly slow, for example:
$ glxgears -fullscreen
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
51 frames in 5.1 seconds = 10.010 FPS
which is rather good comparing to the behavior of glxgears without fullscreen and maximized (showing the window borders and panels) which is aroudn 5 FPS.
This is the same for both Unity 2D, standard 3D Unity (in which also just moving windows around is painful) and KDE (in which everything is ever slower which makes KDE practically unusable).
I've had the same behavior since I installed Ubuntu 11.10, and its the same now with the 12.04 alpha. I have two identical machines running 12.04 - one is using the standard Ubuntu (with KDE installed as an option) and the other is installed with Kubuntu. When I run glxgears on the Kubuntu machine, its not running in synchronized mode and the fullscreen framerate is reported around 50 FPS, though the movement is almost as choppy as in the Ubuntu machine (so I don't understand what is going on). In the Kubuntu machine, KDE can't do OpenGL desktop effects at all - I get errors when I try to enable that, though glxgears does work.
A slightly older machine (running chipset 82801H - ICH8 family) works fine.

Nothing obvious in the logs. Do you have the same problem with a livecd? Is glxgears the only app you've tested with? It's not a benchmark, btw.
