[John Hendrickx <John2.Hendrickx@xxxxxxxxx>]

I have 10.04 on a test partition with 9.04 as my regular system (9.10
never worked satisfactoryly on this machine). Lucid works fine in most
respects, no problems switching windows or so. But games like BZFlag or
Briquolo don't run smoothly under Lucid, although they run fast enough
under 9.10.

Here are some graphics benchmarks I found on
https://wiki.ubuntu.com/X/KernelModeSetting

glxgears:
9.04: 309 FPS
10.04: 484 FPS

GLBlur
9.04: FPS 36.5, load 63.5%, polys 28
10.04: fps 17.2, load 82.8%, polys: 28

GtkPerf
9.04: 11.4 seconds
10.04: 16.6 seconds

So for glxgears, 10.04 performs slightly better, but for GLBlur or
GtkPerf, 9.04 shows much better performance. You can see that GLBlur is
much smoother under 9.04. I thought perhaps 3D acceleration was turned
off but it is turned on.

The computer in question is a Packard Bell EasyNote MZ35 laptop. Ubuntu
9.10 tended to crash so I've reverted to 9.04. 10.04 beta1 and beta2
liveCD wouldn't even boot properly, also a Radeon Xpress 200m related
problem. RC and later run fine, but suspend/hibernate don't work.
