[Lxde-list] Automatic monitor switch on external source connect

[Journeyman <jm...@st...>]

Hello there lxde-people,

I've just joined the mailing list to ask for a little help about the 
feature mentioned in the subject or for advancing my proposal, lacking 
an already existing solution.

I use LXDE on Lubuntu since (I think) 12.x an a Dell XPS13 and I like it 
very much.

Moving to and fro my office I often plug and unplug an external monitor 
and it's a bit boring to manually run a command to enable both or return 
to a single desktop.

There are a lot of guides out there to create desktop buttons, polling 
scripts on xrandr and stuff like to partially automate the switch. What 
I wanted is something a bit different, I didn't want something that 
polls, I wanted something that is triggered. OSX and Unity already have 
(I see my colleagues at work) this utility under the hood, although I 
don't know how it works.

So after some searching I've put up a script that executes an automatic 
monitor switch when an external source is plugged or unplugged. The 
switch is triggered by the relevant UDEV kernel event, so there's no 
polling:

First question, did I miss by any chance a tool to do that? I'd be glad 
to switch from my homemade solution to something more reliable.

Second question, if the answer to the previous question is "no", would 
LXDE be interested in having me provide a wrapping to this script in 
some kind of UI so that a user could:
- use randr to define two or more monitor setups
- install all the needed stuff to automatically switch monitor 
configuration like I did.

I could work on such a simple tool when my spare time allows.

I'd be superhappy to have your comments and suggestions on the matter!

Thanks,
Antonio
