Bug Description
Acording to the information that Intel provides on their website about the intel D945GCLF2 with atom 330, it should have a Intel® 945GC Express Chipset, and it uses for video the Intel® Graphics Media Accelerator 950, so i dont which driver ubuntu uses for this device, because there no grapical user interface to point the vga driver, KDE4.2 only handles screen resolution, no chaning of drivers for vga.
http://
But when i look into hardware plasmoid i see this:
CPU: Intel(R) Atom(TM) CPU 330 @ 1.60GHz
GPU: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)
Audio: HDA Intel (ALC662 Analog)
Audio: HDA Intel (ALC662 Digital)
Audio: HDA Intel ()
Netwerk: Loopback device Interface
Netwerk: Bridge Interface
Netwerk: Networking Interface
So it seems that Ubuntu sees it as a different device? or am i wrong here? I just hope the performance overall of intel gma would improve, because it seems xorg has serieus performance issius with intel gma''s.
This is the result i get when running glxgears

I have enabled kwin desktop effects, and seems overall okay, but i believe that the performance could be better, i think i just dont ask much, but there is probably a serieus bug, and i ask you please go investigate this, there are more bugs like this on, and none is important enough acording to ubuntu to be fixed as fast as possible, i know that 9.04 is unstable but thats just why we should get things have stable in less then 4 month, he intel issues is already there since 8.10, it was reported about slow performance on gma 965, it seems this is on more gma''s from intel and could be a bug in xorg itself. 3d

Maby intresseting, but i have installed osx 10.5.2 on my intel atom 330 machine and i did get better results then in kubuntu 9.04 alpha 2, so are we using the good drivers? Is the performance stable?
this are the system bechmarks result, seeing that opengl performs pretty well.
