Mumble overlay should work as soon as you launch games on Linux

[NothingMuchHereToSay]

I'm on Ubuntu 14.04 64 bit and I think it's ludicrous to have to type in a command to launch the Mumble overlay.

Do you have a suggestion how to technically solve this?
Does Ubuntu, or better yet a GNU/Linux service provide this functionality?

The ugly way would be to set LD_PRELOAD globally, in such a way that all programs have that environment variable set. Not that I'd recommend doing it in this way, but it should be possible, I think. (It is on OS X, but might require more hackery on Linux).

Another possibility is to ask Valve nicely to allow you to be able to set environment variables for games in the same way you can set command line args. Alternatively, running Steam with mumble-overlay might already make any launched games inherit Steam's LD_PRELOAD, though who knows - they have their own overlay as well...

And there are other possibilities as well, since this is Linux we're talking about. The problem is just finding a method that the community as a whole would accept. :-)

Why not just add a button to the tool bar that turns the overlay on and off for all platforms? If I recall correctly, Windows has processes it listens for. This way people can turn it on and off at will for the applications they want or don't want to use it with.

The question would remain how this shall be done? Setting LD_PRELOAD can only be done globally or when starting a given process. So that wouldn't work.

With vulkan you just can have a global systemwide overlay layer akin to mangohud or steam overlay or https://github.com/nowrep/obs-vkcapture with mumble itself deciding which apps get the overlay and which don't.

What I don't understand is why wiki/documentation says that vulkan is supported on linux "since 1.3.0" so is there support for it or not?
