I also get this problem. ATI HD 4670on 64 bit. User switching results in blank screen, and Ctrl+Alt+f1 / f2 etc doesn;t work. Neither does Alt+ SysRq+(anything). Machine is completely dead needing a power off.

This also happens when switching display - Ctrl+Alt+f1 is OK, but switching back to to GUI with Ctrl+Alt+f7 results in the same locked-up machine.
