I'm new to Linux and to this forum, I recently purchased a DELL XPS-13 with Ubuntu 14.04.
Until now suspending my computer, either by closing the lid or clicking "suspend" in the menu did suspend my computer. I even sometimes had some problem waking it up, with the screen remaining black when I opened the lid. Now this issue seems to be fixed, but whenever I close the lid or click suspend, my laptop's screen remains lit, and just shows the login page, which, as you can imagine, has an impact on battery life.
I don't know why, but I can't get the screen to turn off when I close the lid or suspend.
I tried to run in Terminal
but none seems to work at all, nothing happens.
I tried running the solution mentionned in this post but nothing seems to work...
Any idea what might be the problem?
Yes I wrote sudo before the command. Here are the results of both commands:
adri@Adri-XPS-13:~$ sudo pm-suspend [sudo] password for adri: adri@Adri-XPS-13:~$ uname -r 3.16.0-37-generic adri@Adri-XPS-13:~$
