Oho - KrazyPenguin is right but first you have to install the 3D drivers, or you may get problems....
Envy (-t or -g) will do it for nvidia and ATI

No! Do NOT install the ATI proprietary driver. It does not work with Beryl (well, not without o whole lot of extra headache). The Nvidia driver is fine, but if you have ATI you should be using the open-source driver.

If you could give us some info on what hardware you are running it would help us trouble-shoot your issues.

Lolo Uila which driver does envy install? Haven't used ATI for at least 5 years...
But to start envy without 3d driver gets you into some real problems....

Depends on what card you have. For most recent ATI cards Envy installs the proprietary ATI (closed-source) driver.

By default the ATI closed source driver does not support composite extensions and doesn't work with Beryl or Compiz. You can get it to work if you run your desktop in an XGL session. To do that involves installing XGL and downgrading Beryl to an older version. I have that running on my test system because the open source driver is very unstable with the 9700 Pro that's in that system. It works pretty well, once you get past the getting-it-to-work hassles. I still haven't managed to get the Emerald themes working, though.

In my primary system I'm running an ATI X800 XT PE and it works great with the open-source driver and Beryl/Emerald. I've got it running on dual monitors now, with dual desktop cubes. It's pretty cool.

I have run Beryl on a Sony notebook with an Intel graphics controller and it seemed to work well. The Intel chip has some 3D acceleration. It's not as fast as recent ATI or Nvidia chips, but it should be fine for Beryl.
