On Wayland, global hotkeys are often handled by the compositor instead. On sway for instance, a config file is edited to launch specific commands when a hotkey is entered. On such compositors, it should be enough to show Albert by configuring the compositor to launch "albert show" or "albert toggle" a hotkey manager in Albert itself is redundant.

Confirming problem, I just installed albert and it's crashing at startup: |

I built Albert with this patch and it fixes the crash at startup under Sway. |

I thought about whether this is the right thing in all wayland environments, and I think it is. I'm not aware of a wayland protocol for requesting a hotkey from the compositor, and if there is it can be supported in a later patch.

Design choice:
- Just hide it
- Tell the user that it can't be done this way and that they should consult the compositor
I personally would go with option 2

You mean like a dialog when you push the button, or a tooltip on a disabled button?
Maybe it can be done separately in another merge request? I'm not sure when I have the time to continue work on this, and in the meantime it would be nice to at least solve the crashes :)

I'm not sure if this fix is missing something, but I'm running on Fedora 31 and the fix doesn't seem to work for me, I'm still seeing a core dump Let me know if I can provide any other testing or information. |

Running into this on a fresh Fedora 31 system. Is there something holding this back from being merged? debug info |

UPDATE 2: Building from the right branch allows albert to go through first run, but when actually trying to use it... $ albert -r$ albert$ coredumpctl infoUPDATE: I'm an idiot. I was in master. Had to pull the right branch.
Disregard the below. Hmm. Built albert from Still segfaults. $ albert -v
$ albert$ coredumpctl infoI'm not smart enough to know if it is the same crash you were trying to fix or something different. |

Any news when this will merge? |

BUMP. Also having this issue on sway, installed from the OBS repo. |

Any idea when this will be merged? |

I also needed albertlauncher/plugins#21 to fix the widgetboxmodel plugin (otherwise it crashed on |
