If you run:

sudo shutdown -h now

Does it turn off?

Hi ,
the title says "Computer does not shutdown" but in description " I have to power it off in order to restart."

What exactly is the problem ? Can shutdown properly the PC from menu ?
or both shutdown and reboot not working ?

Also we want little more info
+++++++++++++++++++++++++++++++++++++
cat /etc/lsb-release && uname -r
lspci -nnk | grep -iA2 vga
cat /var/log/Xorg.0.log | grep -e EE -e WW
+++++++++++++++++++++++++++++++++++++
above are commands you should give in terminal (ctrl+alt+t , to open it) . One line at time . We want the results .

Thank you

The computer turns off the monitor and it seems to go into sleep, but it never finishes it off. It is some kind of coma, it
does not work anymore, but it is still not completely switched off.

Hi ,
can you remove the nvidia proprietary driver ?
Did you have a problem with nouveau (open source) and have installed nvidia ?

If you didn't have any problem with open source , but you installed nvidia because additional drivers suggested , then remove nvidia driver.

From terminal
+++++++++++++++++++++++++
sudo apt-get purge nvidia
sudo reboot
++++++++++++++++++++++++

Then check if removed correctly with this command
+++++++++++++++++++++++++
lspci -nnk | grep -iA2 vga
+++++++++++++++++++++++++
in "Kernel driver in use" should say "nouveau"

Then try to shutdown or reboot your pc and see if fixed.

Thank you.

Sorry , I forgot the asterisk and one more important command

Here are the commands in case you want to uninstall nvidia drivers from terminal

+++++++++++++++++++++++++++++++++
sudo apt-get purge nvidia*
sudo apt-get install ubuntu-desktop
sudo reboot
