nosuspend allows users to avoid suspend or shutdown even on privileged level
(e.g. root) when a running user process shouldn't be interrupted.
To accomplish this, nosuspend sets the systemd-inhibit flag with UID 0/root in
order to block computer suspend while another command-line operation is running.
This program could install a PolKit rule allowing active users to run
systemd-inhibit with the UID 0/root flag and without a password. The default
setting requires a password.
nosuspend needs the commandline tool screen to be installed
- clone the repo
cd nosuspend
Multiple options for the next step:
3A. most secure build: make secure (or just make, which does the same by
default)
This will build with a policy file which requires you to enter root passphrase to use nosupend.
3B. operate without passphrase (less strictly secure): make relaxed
This will build with a policy file which allows nosuspend to run without asking for a root passphrase.
- run
sudo make installto install nosuspend to the system
To uninstall nosuspend, cd to the nosuspend directory and run:
sudo make uninstall
To use nosuspend, simply run before another command as in:
nosuspend appname -parameter for appname
Full bash completion is supported for easy command substitution.
Note: when a suspend signal is sent while nosuspend is functioning, a dialog may appear saying something like "Authentication is required for suspending the system while an application asked to inhibit it." That dialog may ask for a root passphrase. Entering the passphrase and clicking "OK" should allow the suspend to go ahead, overriding nosuspend. Ignoring, closing, or canceling the dialog will let nosuspend continue in blocking suspension.
