"Installing XGL + Beryl on Ubuntu Edgy Eft with an ATI card is relatively easy once you get the fglrx video driver working properly (that can be the tricky part)."
Tricky indeed, they weren't kidding. I've exactly the same setup, and apparently it does not work with my ATI video card (or at least there are a lot of complications with it). I tried pretty much every method under the sun (well, under google
) to get it to work and it won't. Luckily a friend had the same video card with the same problem so I'm gonna get him to look at it (and hopefully fix it) today.
