If you need to forward X the old school unencrypted way, you need to add one line to gdm’s custom.conf file and restart the desktop. Without this, the old “xhost +” won’t do a thing because the out of the box Xorg configuration includes the nolisten tcp flag.

This is how-to-Install 3D desktop effects on a vanilla Fedora 10 installation (I tried this on a freshly installed Fedora 10, installed from DVD). Basically all you need to do is get 3d hardware acceleration enabled for your video card and then install the fusion-icon package and reboot. In the past this was easier said than done.
