## GDM suspend

Recent versions of Fedora running GNOME desktop unexpectedly suspend.

For systems that also happen to be servers, this is a problem. The

apparent solution is to add a `gdm` profile, as outlined on

StackExchange

[Disable GDM suspend on lock screen](https://unix.stackexchange.com/a/746767).

Such a `gdm` profile works great until `gdm` itself crashes

and the system again suspends.

## Systemd-inhibit

Systemd provides a utility for blocking suspend: `systemd-inhibit`.

Similar to `nohup`, it's intent is to prevent interruption of

a long-running process.

## inhibit-suspend.service

This package provides a systemd service, *inhibit-suspend.service*,

that invokes `wait-for-signal`, which simply sleeps until it receives

a designated signal (SIGUSR1, by default). By invoking

`wait-for-signal` via `systemd-inhibit`, this is enough to prevent a

slightly unstable desktop from suspending the system. *Hurrah!*

## Installation

Provided your **systemd**-based OS has **GNU make** and a C compiler, run:

```bash

git clone https://github.com/revolution-robotics/inhibit-suspend.git

make -C inhibit-suspend

sudo make -C inhibit-suspend install

sudo systemctl enable --now inhibit-suspsend

```
