I recently installed mythbuntu on my desktop. I have been running Ubuntu for about a year now, and decided I wanted to turn my desktop into a PVR (tivo for desktop). I started with a fresh install, and it seems like I have a mixture of gnome and X. I don't have the standard gnome menus, I have xfce menus, and I can't drag launchers from the menu onto the panel like I could in ubuntu. I'm also missing the 'system' and 'places' menus. It also doesn't automatically mount my external hard drives or my second internal hard drive.
