I have a fresh install of Linux Mint KDE 14.
My first surprise is that I can not simply shutdown the system by clicking on the button "power off" : I have just two option : "suspend to RAM" or "suspend to disk". But where is the normal shutdown !?!
And the bug is : when I choose "shutdown" and wait the countdown, then it stops and never power on at all (neither the Bios is unreachable !). I fix temporary the problem when I put off the RAM and put it again...
So now I have to open a terminal and write shutdown -h now" to power off.
What can I do ?
