A workaround is suggested by user radwis in thread http://ubuntuforums.org/showthread.php?t=276642
Add the boot option acpi=force to the kernel line in /boot/grub/menu.lst. It works for me. Here's my Edgy boot clause: title Kubuntu Edgy 6.10, kernel 2.6.17-10-generic root (hd0,2) kernel /vmlinuz root=/dev/hda3 ro acpi=force initrd /initrd.img boot -- [edgy]"Shutdown button" does not work. https://launchpad.net/bugs/65962 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
