If I try to shutdown my computer it simply takes me back to the login-screen. I looked around and found :
Type in terminal:
sudo gedit /etc/default/grub
- Find the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
- Change this to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
- Save the file and close the file.
- Finally, in terminal:
sudo update-grub
But now there is a new problem when I try step 5 it says:
*myname*@ubuntu:~$ sudo update-grub
[sudo] password for *myname*:
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
*myname*@ubuntu:~$
I am new whit linux and dont know what to do.
