Ubuntu 12.04 64 bit same behaviour


Problem (unsolved)

At shutdown or restart the computer may or may not hang.

  • doing a shutdown from the desktop will logout instead most of the times (9 out of 10) and show the login screen
  • shutting down does not complete, sometimes a trace shows up that mentions FGLRX, it does not timeout, it keeps hanging indefinitely
  • seems to be happening more often when a truecrypt partition is mounted

Suggestions and reports:

Suggestions

Modify grub configuration to show log messages 

sudo gedit /etc/default/grub

Change: 

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to: 

GRUB_CMDLINE_LINUX_DEFAULT=""
sudo update-grub


ACPI off (failed)

Modify grub configuration as above to turn off ACPI (Advanced Configuration and Power Interface) at boot. 

GRUB_CMDLINE_LINUX_DEFAULT="acpi=off"

Pre-stop script (failed)

Add the pre-stop script to /etc/init/dbus.conf before 'exec' 

sudo gedit /etc/init/dbus.conf
pre-stop script
   trap "TERM signal" TERM
   /bin/umount -a -t cifs -f -l
   trap - TERM
end script
