Public bug reported: I'm running a Dell Inspiron 1520 with an Nvidia GeForce 8400M GS. The computer hangs on shutdown and reboot.
I tried adding INIT_HALT = POWEROFF to /etc/default/halt and that seems to stop the problem with rebooting. I tried changing video drivers from 295.40 to 290.10 as I read in a thread on launchpad. That did not help. I did a clean install and the problem persists. I didn't have this problem on 11.10 although I've heard that some people did.
