after upgrading form Kubuntu 7.10 i have problems running everything (at least it seems to me like that) using OpenGL
This means for examples: Games like Supertuxkart, all the opengl screensavers and zattoo (which gives me the error message:"Window system doesn't support OpenGL" - thats why i think this could be the problem)

In Kubuntu 7.10 there was an option under
System-settings -> Advanced -> restricted drivers
where i had to mark the option for the graphic acceleration (hope this is the right word for that) to get zattoo to work.

Now on Kubuntu 8.10 this option is no longer available in the system settings (the option Restricted drivers ist not available at all) - so as i'm not that much an expert i don't know what to do...

if someone needs:
the graphic card is dell standart (about 3 years old)
lspci gives:

under system->settings -> Display -> Hardware
there is also the Nvidia GForce FX (Generic)

The graphic card driver should be the standard to - as i just did the update - nothing more on this. nvidia-glx-new is installed.

would be great if someone could give me a hint as i'm already tring to solve this for about 3 weeks - without success.
