Question: How to assign a script to run when selecting the suspend option on the power menu?

I have a Sony VAIO laptop with an AMD Radeon graphics card. I would like to be able to disable/enable the discrete graphics card. I have no problem in doing this but it causes problems when suspending & resuming from suspend.

When the session is resumed from suspend (with the discrete DPU disabled), the fan will spin up uncontrollably, what I would like to do is edit the suspend script or assign a new script to the suspend option on the power menu. This is so I can re-enable the GPU before suspending. Power Menu

EDIT: After some research I think it has something to do with the files in /etc/pm/sleep.d/?

If I put a custom script in there would it be run when suspending and resuming from suspend?

How do I differentiate in the script between suspending/resuming?


You are right. You have to write a script and save it to /etc/pm/sleep.d/. The difference between suspending and resuming is given as a parameter to the script:


case "$1" in
        # executed on suspend
        # executed on resume

If you also want to do it for hibernate, the arguments would be hibernate and thaw.

  • I'd seen this in other scripts and was wondering on the specific requirements for such a script. Thank you :) – danielcooperxyz Feb 25 '13 at 13:38
  • Hi, tried this on my Dell 5570 running ubuntu 14.04 to get it to turn my touchpad on, if I'd turned if off before suspending. for some reason, the command tp_id= ()xinput list | grep -i touchpad | awk '{ print $7 }' | sed 's/id=//'() is not returning the id, while this command does work from the command line. Can you see any reason why it wouldn't? For other purposes you script works great. Thanks! – Leo Simon Mar 11 '16 at 0:16
  • Sorry, in that previous comment, I tried to put backticks into the script fragment, but the minimarkdown language defeated me. the ()'s are meant to be replaced by backticks – Leo Simon Mar 11 '16 at 0:27
  • @LeoSimon Hey Leo, the comments are not the right place to discuss such a follow up question. I suggest you ask an entirely new question. This way a lot more people will see it and be able to help you :-) – André Stannek Mar 11 '16 at 8:55

    You may need to use /lib/systemd/system-sleep/ instead. – SimonT Oct 20 '17 at 5:17
