Maybe this is a bug in ACPI. I found the following work round (from various sources) which works for me:
Edit file /etc/modules: add line "apm" (no quotation marks) Edit file /etc/default/grub: at GRUB_CMDLINE_LINUX_DEFAULT add "apm=power-off" in quotation marks and directly after any other kernel line commands without leaving a space between them (if I left a space it didn't work!) Then in terminal type: sudo update-grub After rebooting shutdown works normally. -- shut down hangs after white ubuntu logo disappears https://bugs.launchpad.net/bugs/507555 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
