[solved] my script in /usr/lib/systemd/system-sleep/ was erroneous

Question

Maybe I just didn't see something I need to do...
I have this script:
-rwxr-xr-x 1 root root 322 13. Nov 10:13 /usr/lib/systemd/system-sleep/resume.sh*
And whether I suspend with the kde suspend thingy or with systemctl suspend, this script does not run on resume from suspend.
The script looks like this:
#!/bin/bash
case $1/$2 in
pre/*)
exit 0
# some lines to put graphics card back to sleep with vgaswitcheroo
esac
Did i do something wrong or do I need to do something else?

Answer 1

I did some further testing with my system, it appears that using the '*)' specifically causes a "Job for suspend.target canceled" on resume, which could be the problem you are facing. It could also be that the syntax for the pre and post are explicitly given, otherwise I don't see a reason why would it print that message.
Given the code:
#!/bin/sh
#can also be /bin/bash
case $1/$2 in
echo "a $1 with $2"
esac
Works and does not produce the above (red) message.
However combining "pre/*)" and "*)" generates the message, regardless of the shell.
I was doing all the suspends with systemctl suspend
So I'd suggest putting a lot of echo statements in your script and then observe the output of journalctl -b -u systemd-suspend (this is where the echo statements get logged) and check for any errors it might throw. And try to use the pre/*) post/*) if you didn't try that yet.
EDIT:
Forgot to mention I was doing all this as root
