Intel GMA950 and 3945ABG Troubles

Installation is on HP tc4400 TabletPC.

I update my working Intrepid installation to the current Jaunty, the same way I did with Hardy->Intrepid.

The first thing I noticed is that my dedicated audio buttons (volume up, down and mute) work again, which they stopped doing when I finally did a clean install of Hardy release.

But my Intel graphics got screwed.

fester@fester-tabletpc:~$ glxinfo | grep renderer
OpenGL renderer string: Software Rasterizer

In /var/log/Xorg.0.log everything seems normal, the driver is loaded and initialized, the chipset is recognised, DRI is enabled.

I tried reconfigureing xorg.conf, and nothing.

glxgears run at ~150fps, and Compiz is unusable.

The other issue is with the wireless card and the kill switch. The card is Mini PCI-E 3945ABG. In the release notes of Intrepid it was stated that currently there are some problems with some configurations, that would be fixed. And yet, with 2.6.28-2-generic the problem is still here. If I boot with kill switch disabled I am unable to enable the wifi card. And if I disable it, while it is running, then most of the time I can't reenable it.

Just checking, as I am running the same 3945ABG wifi, it works if enabled under jaunty BUT if you turn it off while it's running or while it's starting then you can't re-enable the wifi? (I'm running intrepid and planning a switch to jaunty after exams :D)

I have exactly the same problem! Worked good in intrepid but compiz is mega slow in jaunty cause of this. Did you find any fix?

Intel graphics are wacked out at the moment. 3945 wireless has had problems since Hardy with the switch to iwl3945: everything from what you described to complete system failures...

Bump. Latest Kubuntu 9.04 Here (alpha 4 + 82 updates) Switching to UXA fixes the graphics performance (introducing a bit of instability, though). BUT the wireless is still a no-go. I used Arch for a while with iwl3945 and had no problems turning on and of the WiFi, whenever I want. It runs the same 2.6.28 kernel.
