HUD (heads-up display) sounds interesting, but I can’t get it to work. (Ubuntu MATE 16.10 Alpha 2)
I’ve checked Enable HUD in MATE Tweak and rebooted, but CTRL+ALT+Space does nothing. I have tried all combinations of left and right ALT and left and right CTRL keys.
Are there some unmentioned prerequisites for this feature?
I notice that there’s no HUD shortcut listed in Keyboard shortcuts. Should I add it? What is the command for HUD?
This is something new in 16.10
And I just now tried it and no go, not even in terminal.
I wonder if it could be a systemd service not starting. Anyhow I will play with it some more and see if I can aleast pin down the problem.
I will let you know what happens 
I forgot
Do you have synaptic package manager installed?
It will list all installed files, makes it a bit easier to figure out whats going on

Hi v3xx,
I use Synaptic all the time and I know that it can list the files for any installed package. But I don’t know what package contains the HUD software and I don’t know the text-mode command for HUD.
What did you want me to look for in Synaptic?
The package is called “mate-hud” but I cannot get it to work in 16.10 either!. 
Looking for the package in Synaptic won’t do you any good!, the controls should be “Ctrl + Alt + Space” but it won’t work, it is also showing in the startup applications list!. 
For what it’s worth:
.xsession-errors shows these relevant messages:
INFO:root:Press space to handle keybinding and quit
mate-session[2576]: WARNING: Application ‘mate-hud.desktop’ failed to register before timeout
mate-session[2576]: WARNING: Application ‘mate-hud-service.desktop’ failed to register before timeout
Running /usr/lib/mate-hud/mate-hud in a terminal window enables CTRL-ALT-Space, but only for certain apps, such as mate-terminal and caja. It doesn’t work for Firefox, or even Synaptic.
Well I played with the gschema and other files until I locked up my desktop.
@wimpy will have to tell us whats going on.
this is what I have seen on HUD installation in any flavor of Ubuntu, there are some App that do not work, the site is in Spanish.
Regards…
mate-hud is currently working on gtk apps only . Both gtk3 and gtk2 are supported exept that it won’t work on Client-Side decorated windows . That was in my case when I installed it . Try to use it on caja or pluma .
