@prateekmedia Just so you know, the Wifi menu doesn't really do much right now, even if it didn't crash. I'd like to eventually get it to talk with NetworkManager over dbus, but it looks like that is more difficult than it really should be. For now, it tries to use wpa_supplicant.

What manages Wifi connections on your system? NetworkManager, wpa_supplicant, something else entirely?

@jmanc3 NetworkManager / nmcli

@prateekmedia I'll get on it

Also crashes for me (Arch Linux)

@D3SOX @prateekmedia does the wifi menu still segfault?

[D3SOX]

Nope, shows a warning about not being implemented now.
