Description

Hyprlock uses the disown shell command that is not available in POSIX shells (like dash). This becomes a problem if the system's /bin/sh is a symlink to the aforementioned dash (as Hyprlock seems to use /bin/sh explicitly). It comes up in the logs as a simple line: /bin/sh: 1: disown: not found

I think that the solution would be to A) keep using /bin/sh and replace disown with something POSIX-compatible (if there is a way to do it at all, haven't dug deep into that); B) move away from /bin/sh to explicit /bin/bash usage.

IMO option A) is the way to go.

How to reproduce

1. Start hyrplock on a system with /bin/sh being something POSIX-compatible like dash;
2. Look at the console/log output.

@PaideiaDilemma wanna take a look att his?

[mradermaxlol]

Having googled a bit, I think that similar results could be achieved by using nohup: sleep 2 && nohup hyprlock --immediate --immediate-render &

One more thing I've been thinking about: is it really necessary to exec shell stuff in a cpp project? I mean, could the same behaviour he achieved by using "vanilla" cpp stuff without resorting to shell commands? Though something tells me that such a solution would already be used if it was that easy.

@vaxerski can't we just use hyprctl dispatch exec and only try to restart when on Hyprland. Wont work on other compositors anyways right?

[vaxerski]

we can, right, isnt that hyprland-exclusive, if so, ye
