Recently, I install Xubuntu 16.04 on my Acer Aspire E1-570G. It wasn't going to suspend when I close the lid, so I used a little trick by uncommenting HandleLidSwitchDocked=suspend on /etc/systemd/logind.conf and it worked properly (when opening and closing lid, everything was OK).

Yesterday, I upgraded my Xubuntu to 16.04.1 by using sudo apt-get update && sudo apt-get upgrade.

My devices suspends when I close its lid, but when I open it back, I just see a command line cursor blinking and after a few seconds it stops blinking and nothing more comes out, have to restart it by ALT+PRT SC and type REISUB.

What should I do to fix this problem?

P.S.: sorry for too much details :)

Try upgrading your kernel. Seemed to do the trick for me.

  • I just started upgrading my kernel from 4.4.8 to 4.8.1 . About the second answer, I followed the instructions there and that's my problem now (read my question again). – Ehsaan Oct 11 '16 at 09:44
  • Wasn't all that awake when I posted that. Updating the kernel was the second answer in that post, which is why I suggested it. Thought you had already updated it and I just read it wrong, which is why I deleted the answer. Glad you've figured it out in spite of my grogginess. – MSchu Oct 11 '16 at 12:10
