I thought the same at first, but I managed to put shortcuts as I like and also screen edges the same as in compiz.
Buzz is that I had to do it manually from “configure desktop” -> “keyboard shortcuts”, but OK, no big deal. Everything works the same.
I have a remark in KDE4 that settings are bit confusing, but at least all are there.
Sorry, I don’t mean to be boring, but did you try without compiz, XGL and emerald and whatever else. Just plain KWin at 4.1 works OK. I had to remove all startup things for compiz and emerald to get my beloved cube work as I wish.
Composite is enabled. When I try to enable Compiz from KDE’s desktop configuration it still says Compiz failed to start and goes back to Kwin.
I tried all the solutions proposed in this topic, and removed Compiz repository from YaST.
Kwin effects, however, work very slow, and I see no trace of the cube even if enabled. Glxgears still reports thousands of FPSs (3144)
