Shutdown function not working

[OzTornado]

Hello
I recently purchased a new laptop without OS and did a fresh install of Kali, there are a few small bugs that I am working on but there is one major bug. When I am in ordinary user and select shutdown or reboot from the applications menu, my mouse pointer and kicker panel disappear and then nothing happens and I have to use the power key to shut it down.

Any suggestions, I have tried putting the line acpi=force into grub with no luck, also sudo shutdown -r and -h do not work

## Edit 2 If I boot to recovery mode and then perform shutdown -r or -h from there I get a message like this "Nouveau refused to change power state" ##

I found the solution add this line to /etc/default/grub

GRUB_CMDLINE_LINUX="nouveau.modeset=0"

then update-grub

After a re-install I had the same problem this time my previous solution dd not work, but this did

acpi=force apm=power_off

added into /etc/default/grub.
