 |
|
I'm running elogind-255.5-r2 + openrc-0.55.1. I wish to have my machine sleep after a period of time, but only if emerge or gcc is not running. In accordance with the loginctl man page, I placed a hook script in /etc/elogind/system-sleep, which checks for any emerge or gcc processes and attempts to cancel the suspend operation if they exist. I've verified that the script is indeed executed on each suspend attempt.
The problem is, my machine suspends 100% of the time.
Pertinent portion of the script: | Code: | #!/bin/sh
case $1/$2 in
pre/*)
if [[ $(ps aux | grep -E "gcc|emerge" | grep -v "grep") ]]; then
echo -e "CANCELLED suspend due to my script"
exit 1
fi
;; |
The man page says I need to print an error message to STDOUT which begins with one of: "CANCELLED" "CRITICAL" "ERROR" "FAILED"
I've tried all four of these words, and in all cases the system still suspends. That piece of code IS executed, because if I redirect it to a file or run the script manually, I see it.
I've placed "AllowSuspendInterrupts=yes" in /etc/elogind/logind.conf, /etc/elogind/logind.conf.d/myconfig.conf, /etc/elogind/sleep.conf, and /etc/elogind/sleep.conf.d/mysleep.conf
Any thoughts/suggestions? |

I assume elogind reads logind.conf only on startup. Did you restart the service ? |

Yes. In fact, I've restarted my entire machine numerous times since I began troubleshooting this, with no effect. There is also the "elogind reload" command which presumably reloads the config files without needing to restart elogind. Either way, still nothing. |

/etc/elogind/sleep.conf and /etc/elogind/sleep.conf.d/* are read whenever anything sleep-relevant happens, even if it only checks whether a specific mode is allowed.
At least, that is the plan for Version 257+, and it has already been implemented in the Version 256 merge.
Anyway, if cancellation by hook script does not work, there are two possibilities:
a) Another power manager interferes and enforces the suspension, like PowerDevil loves to do, or
b) I have managed to create a new bug.
Secretly, I hope it is the latter because that would be a problem I can do something about. But it is also a bit unnerving, as running hook scripts and making them break off power/sleep-related actions was something a lot of energy, time, and testing ran into.
The best thing would be to open an issue at github.com/elogind/elogind, and I'll have a look, maybe next week.
