I just did a completely fresh install of 13.04 64bit (actually did it a second time in case it was just a fluke the first time). Everything went smooth. It boots up to a login screen, so I give my password, and then it takes me to my desktop... and then nothing works.
Unity shows up, but is unresponsive.
The top gray bar appears but contains nothing, not even the gear icon that you use to log out / reboot.
I can move the mouse around, but I can't click on anything.
I can press Ctrl+F# to get to tty#, and from there I can do a terminal login and, say, kill gnome-desktop, which takes me back to the login screen, only to have the exact same problem again if I try to login again. The login screen is otherwise completely functional - I can reboot, shut down, change settings, etc., but the moment I try to login from any user account, it breaks.
For the record:
I've installed Xubuntu 64bit on this computer, and it worked fine. However, I want Ubuntu.
Edit: Just tried a fresh install of Ubuntu 12.10. The first boot worked fine. After installing updates and rebooting, it experienced a very similar problem - on login, unity is broken. I can right click and do, like "Set background" or Ctrl+T to open a terminal, but the windows that open don't have window decorations (like no Close button or menus)
I have noticed something that may or may not be relevant. In both Ubuntu 12.10 and Xubuntu, whenever I log in, I get a Crash Report that says Compiz has crashed. I tried installing the proprietary graphics drivers, but that didn't help.
