I have discovered, with the new Xorg 1.6 and the newest Intel drivers for the graphics card the 3D performance have been upped slightly. But compared to the old i810 drivers, it is still not as good. Though a lot of new features as KVM and such have been implemented.

From my experience the Intel drivers are still a bit buggy. When I have them enabled the newest version does not allow me to rotate my screen as I could do easily before, now it just turns my screen off and I cannot go back and have to restart the computer. Pretty annoying.

The Digitizer works fine with the newest Xorg. You just have to use the development package instead of the stable, since Xorg went over to HAL and moving away from the static xorg.conf, though you still have to load the wacom module in your xorg.conf, and you can still use the Device sections as always. This can probably be done with a fdi file too, I have not investigated that yet though.

I am going to test out Xorg 1.6.1 soon, since it just came out and see if it helps out with the rotation issue.

EDIT:

It seems that everything works fine in Xorg 1.6.1, rotation of the screen, linuxwacom and so on, AWESOME!

If you do not already have a ~/.Xdefaults file create it, and add the following to the file:

Xft.dpi: 96

96 is the DPI size you want.

After this is created and edited run the following command to apply the setting:

xrdb -merge ~/.Xdefaults

Now restart Xorg and the DPI should be changed to the stated in ~/.Xdefaults
