Once again I need a workaround to deal with my almost broken notebook graphics card: It does not wake up after suspending!

The Ubuntu 14.10 system is waking up, but the display stays off, so I have to press the Power button and blindly navigate to the "Shutdown" option, to avoid a hard power off.

I already disabled suspending for all of my user accounts by following this answer. However, I now have seen three times when it actually DID do suspending!
That was:

  • once after I let my notebook on over night (can't remember last state...)
  • once after I closed the lid before I logged into any user account after boot
  • once when the notebook was not in use quite a long time (few hours max.) after leaving it on the lock-screen

I think somehow it is still allowed for the system to use suspension and that there is no rule set for the login/lock screen.
Now, can I disable the suspension functionality there too?

Update:
I recently installed lubuntu-desktop to try LXDE instead of Unity. Now in Lubuntu mode, I can not disable suspending at all. Closing the lid does a suspend which also causes the screen to die until I reboot.
So the solution has to be independent of the used DE!

  • For a laptop lid (depends on your computer's setup - could you add info on your computer's model and graphics & drivers (lspci -v), as well as symptoms of suspending and the output of free -m) doing something with logind might help (I prevously have covered this here and here). Configuring IdleAction* might override stuff as well. – Wilf Mar 01 '15 at 23:01
  • @Wilf thanks for responding. Laptop is a noname model, not even service manuals available. If you want to know anyway, it's a MaxData Pro 6100 iw, gfx card is a nVidia geForce Go 7400 but fried/defect(?), driver is the default xorg, no proprietaries (they don't work at all). – Byte Commander Mar 01 '15 at 23:12
  • @Wilf My symptoms are described in the second paragraph of the Q. More detail: system wakes up (I hear sounds, hdd is used,...), but the screen stays black and without background lighting. I can press my power key to open the shutdown/restart/whatever popup (blindly, without seeing anything, of course) and navigate (guessing) with the arrow keys to shutdown, hit enter and wait untill it is off. Then I have to wait another 10-20 minutes until I can reboot, because may gfx card gives me a now white screen (that slowly fades to a strange grey pattern) if I power on while it is still warm. – Byte Commander Mar 01 '15 at 23:29

    @Wilf Oh, and I modified the logind.conf file as you described it, but I don't want to test it right now, because I still have some important things open I can not finish yet. And I still need a solution that covers more than the lid closing, anyway. – Byte Commander Mar 01 '15 at 23:32
  • did you find any solution to your problem? – Alex Jones Mar 08 '15 at 12:52
  • @edwardtorvalds No, logind.conf was not the right solution. It did not affect LXDE as I remember... I still need something that disables suspending for all triggers (laptop lid closed, low battery, inactive time, shutdown menu, terminal command...) from all users (3 different accounts, nobody logged in), on all DEs (currently Unity, Cinnamon and LXDE) and in best case independent of the used distribution. – Byte Commander Mar 08 '15 at 15:15
  • i assume this means you didnt find any solution :( – Alex Jones Mar 08 '15 at 16:13

I found the solution on Server Fault:

We have to create an executable script in /etc/pm/sleep.d/ that will cancel any hibernate or suspend actions.

sudoedit /etc/pm/sleep.d/000cancel-hibernate-suspend

The content of this file should be:

#!/bin/sh
# prevents hibernation and suspend
. "$PM_FUNCTIONS"
case "${1}" in
  suspend|hibernate)
    inhibit
    ;;
  resume|thaw)
    exit 0
    ;;
esac

Now make that file executable:

chmod 0755 /etc/pm/sleep.d/000cancel-hibernate-suspend
