When you use 3D desktop effects (KWin, Compiz), does the canvas of

With the final release of ubuntu 8.10 the result of glxgears stays
around 440 fps. I can confirm that the message about TTM not being
available disappeared indeed.
Is there any hope the performance will ever go back up to where it was
in ubuntu 7.10?
--

for the record, the message about TTM is purely informational and

I'd like to point that, even if this 59.* frame rate is due to vsync, it
doesn't behave nice (like if it was vsynced). Tearing is still there.

59.xxyy frames per second looks like an indication of vsync is being
used.
But I also find my X3100 performance too low.
Do you guys with X3100 have problems using Celestia? Here I get bad
performance, missing textures and other weird artifacts.

I can confirm the 59.xx frames problem with i915 and i965. Looks pretty much
like vsync which wouldn't be so bad.
Btw. textured video seems to be activated per default again but it doesn't seem
to so slow but I haven't made so much tests.
I can confirm the flickering too on my laptop with i915

On a test machine, a strange flickering can be seen which occurs during
the first 10 seconds of opening the GNOME desktop. This wasn't before

Same problem here, with an intel x3100 card (on a Samsung Q45).
Up to 8.04.1 (Kubuntu) I was able to use KDE4 'desktop effects' easily.
Also, sInce upgrading to 8.10 Alpha 3 (from 8.04.1), desktop effects are not
working, enabling them results in a mainly black, garbled screen.

I have now found a workaround for the issue.
I think it basically is to do with the upgrade from XAA to EXA
acceleration.
EXA appears not be working with the Intel GMA 965 (GM) chipset
(including the Intel X3100).
Upon editing my xorg.conf file to add references to XAA I now have

Also, remove (or comment-out) any lines in your xorg.conf file referring

And one more thing, I'm not sure it's essential, but it may be wise to
ensure that you specify the driver as 'intel' in your Device Section.
