kdotool calls journalctl from systemd to fetch debug logs. So if you are not using systemd, it will fail. I'll add a test to handle this scenario.

Thanks for reporting this.

Thanks for the heads up about this. I was struggling with this as well on a non-systemd system, even going so far as using strace to try to figure out what it's calling and could never find any reference to journalctl. I didn't think to just look at the source code. Commenting out the journaltcl stuff makes it work just fine.

Happy to be able to test this out, now. I've been struggling with finding a good xdotool replacement for wayland that can not only send keystrokes but also activate windows to target that output. kdotool is the only utility I've found so far that seems to be able to do this.

@nitro322 Glad this is useful for you. I also changed the code to not call journalctl unless --debug is specified. And it won't fail when journalctl is not found on --debug.
