Vidyo with Ubuntu and i3wm
Mozilla uses Vidyo for virtual meetings across distributed teams. If it doesn’t work on your laptop, you can use the mobile client or book a meeting room in an office, but neither of those solutions is optimal when working from home.
Vidyo users within Mozilla can download a .deb or .rpm installer from v.mozilla.org. On Ubuntu, it’s easy to install the downloaded package with sudo dpkg -i path/to/the/file.deb.
The issue is that when you invoke VidyoDesktop from your launcher of choice (dmenu for me), i3 does what’s usually the right thing and makes the client fullscreen in a tile. This doesn’t allow the interface to pop up a floating window with the confirm dialog when you try to join a room, so you can’t.
mod + shift + space
Mod was alt by default last time I installed i3, but I’ve since remapped it to the window key (as IRC clients use alt for switching windows). Some people use caps lock as their mod key.
mod + shift + space makes the window floating, which allows it to pop up the confirmation dialog when you try to join a call.
Float windows by default
Alternately, stick the line:
for_window [class="VidyoDesktop"] floating enable
in your ~/.i3/config.
