Toshiba Satellite L855D with fresh 14.04 LTS install, will not suspend, screen goes dark for 2 seconds, then shows the lock screen.

Another post suggested trying:

sudo modprobe toshiba_acpi

but this has not made a difference.

My computer is an AMD A8-4500M APU with Radeon(tm) HD Graphics × 4 Gallium 0.4 on AMD ARUBA.

Any ideas?

  • You're possibly seeing this bug: bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/… . Try removing 'light-locker' and 'light-locker-settings' and installing 'xscreensaver' to solve the issue of buggy suspend/resume. – landroni Apr 25 '14 at 6:25
  • I disagree this is off-topic. I'm having the same problem. I don't find it substantially any different than "I'm having trouble with my apache.conf" or "can someone explain how to find the Ubuntu version I'm running"; those questions are not closed as "off topic". Would it have made a difference if the OP phrased the question as "how to I make Ubuntu 14.04 suspend? When I select the menu, it doesn't." ? I also find this post similar to askubuntu.com/questions/763085/…, but it has not been closed as "off topic". – Dan H Sep 12 '16 at 16:45
