Comment 7 for bug 459037

Hy!

I think I have the same problem...

To reproduce it...
Login to a fresh karmic install (i have an nvidia gpu so dekstop effects are off by default)
Notice the beautiful fade effect when xsplash disappears and then get to the fully working desktop
Then enable desktop effects (install the proprietary nvidia drivers)
Log out
Log back in
Notice that xsplash flickers when compz starts the mouse appears the "progress bar" (I don't know how to call it) freezes for some time and then xsplash simply disappears (without fade effect) and you got a half loaded desktop... (it completes loading in some seconds)
