"To get rid of the shutdown beep (and perhaps making that last step redundent) you should blacklist the pc speaker:
In a terminal type "gksu gedit /etc/modprobe.d/blacklist.conf" =>This will open gedit, go to the last line in the file. Type "blacklist pcspkr" without quotes onto a blank line at the end of this file and then save and close gedit." ------------------------- "blacklist pcspkr" did not work for me. I still had the beep at shutdown. Instead, I did the following: sudo modprobe -r pcspkr This fixed it. Seems to work across reboots, too. -- system beep in jaunty is the most annoying sound known to man https://bugs.launchpad.net/bugs/331589 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
