Problem Quitting

Post by georgeg »

I'm trying to run Mint 3.0. While restarting the computer works pretty much as expected, selecting Quit to shut down the PC when I'm done for the day, doesn't work as expected. The computer doesn't shut down, it just goes to a black screen with a Mint logo in the center. Is this normal behavior? How am I suppose to know when its safe to pull the plug? (No, I don't leave my PC powered up 24/7)

How old is that PC? Could be that ACPI is causing problems and thus the OS can't properly power off the PC. On some older machines it won't work properly without some minor workarounds ....

If you want to try it out:

Edit /boot/grub/menu.lst as root (you have to type this into a terminal):

Code: Select all

sudo gedit /boot/grub/menu.lst
Locate the entries that load your OS, they might look something like this (my stuff is heavily modified so it most likely will look different):
  • ...
    ## ## End Default Options ##

    title Cassandra, kernel 2.6.21.5
    root (hd0,4)
    kernel /vmlinuz-2.6.21.5 root=/dev/hda6 vga=791 ro quiet splash
    initrd /initrd.img-2.6.21.5
    quiet
    savedefault
    ...
Locate the line I highlighted above and add these parameters:

Code: Select all

apm=power-off acpi=force
The line should now read something like this:

Code: Select all

kernel          /vmlinuz-2.6.21.5 root=/dev/hda6 vga=791 ro apm=power-off acpi=force quiet splash
As mentioned before, please apply some common sense here! Don't copy & paste my entries 1:1 -- this will probably result in your system being hosed. Just add the entries I mentioned above so that the line in your boot loader config looks similar. Leave the other entries and parts untouched :wink:

After you have applied those entries, reboot your system and try again. Does the system properly power-off now?

Thanks. That did the trick. Now, Mint shuts down properly.
