Ubuntu

The system doesn't shutdown

Asked by Ricardo Marcelo

Hello everybody,

This weekend I've installed Ubuntu 7.10, but there is something wrong with it. I have an ACER Travelmate 260, if ti is necessary to know. The problem is that when I select the shut down option in the panel the screen becomes black, and all the functions suspended (I mean I including cannot run crtl+alt+F1 or F4 or F6 or whatever) but, actually, the computer doesn't poweroff, someone could please help me (I become nervous to poweroff the computer with the poweroff button...)?

Please edit the file /boot/grub/menu.lst and add acpi=force to the default kernel parameter

Please open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo gedit /boot/grub/menu.lst

give your user password when requested, you don't see nothing when you type it, then press enter.

Search the row

# defoptions=........ your options

and add the "acpi=force" parameter

# defoptions=........ your options acpi=force

save and exit

then type:

sudo update-grub

Reboot your pc, then try to shutdown

Hope this help

Thank you very much. This works perfectly! I would just ask you for an explaination why it works, if you don't mind... I become nervous for "forcing" my system doing something without knowing what.

Thank you again!
