It’s Not “Xgl”…. It’s “Desktop Effects”
I have found that many Xgl-knowledgeable people are having trouble setting up Desktop Effects because they try to do the same setup as they used on early SLED10 betas and on SUSE Linux 10.1 (or Ubuntu, or Gentoo, or…) Ironic that people are messing up because they’re too experienced, methinks. They go about it the hard way.
