Comment 7 for bug 882817

From the clean installation of 11.10 64-bit I have the same problem. So far I wasn't able to shutdown/restart my laptop HP 4520s (if it helps). I also tried the suggested command above, no success. Even if I get to TTY1 (or any) and try to sudo shutdown the pc just hangs up on purple ubuntu screen. When I kill lightDM, it hangs up too. Well, if I can be of any assistance here, sending logs or so, plase tell me, for the thing is becoming a pain in the ***, yes there.
