I am updating LXQt on NixOS to the recently released version 0.13.0.
When starting LXQt for the first time a dialog window appears asking to select the default Window Manager. It seems that this is a new behavior in this release.
The list is empty on my test system, although openbox is installed, and I cannot start the desktop environment. Probably it has to do with the non conventional way files are layout on NixOS.
How is LXQt getting the list of window managers to present in this dialog window?
