Hmm, this is weird. After sucessfully installing Gnome 3.2, I made these

Now I do not "see" the mouse cursor anymore. The mouse cursor is "just
invisible", but it is still there. But it is not rendered anymore, not in kdm,
and not in gdm. If I start X via "startx" as root (then twm is used), I see a
mouse cursor, but it is corrupted. If I log into KDE/Gnome by using kdm or gdm,
and I move the invisible mouse around, I see some animations happening on the

Unfortunately, there are still lots of glitches in KDE as well as in Gnome 3.2.
I see lots of artifacts. Even in twm (plain startx) things are not rendered
100% correctly. However, if I look at KDE now, things seem to be worse than a
few hours ago before I installed Gnome and before I lost my mouse cursor. Any
idea whats going on here?

I'm really confused because I do not see the point why or when the mouse cursor
disappeared. I still do not use a xorg.conf, the kernel is the same, and the
kernel command line is the same. I remember that installing gnome required some
changes regarding the use-flags of my Gentoo-based box, but if I look at the
list of installed and reinstalled packets I do not see a candidate for this

Fiddeling with the HWCursor-Option in a xorg.conf didn't work either.

I'm using the newest mesa, libdrm and xf86-video-ati.

Any ideas?
