I'm not sure if such scenario fits average use case. How often do you have
luxury to have access to monitor an hour before. In business meetings its
quite rare situation.

Also how about university teachers? Each room has its own projector,  does
it mean that person should have to reconfigure display on each room. What if
he is a damn good teacher and works in many universities where gives 2-3
presentations/lessons daily?

So in reality tying to specific display ID might not be the best idea...

On the other hand, remembering what profile was used with exact display is a
great idea (on next uses it just auto switches to preferred profile) :)

Cheers,
Lukas

</div>I agree. I would go even further and add I don&#39;t think we need \
profiles. Assuming displays return some kind of unique ID, it would be smarter \
IMO to remember configuration by display combinations: 
 
Let&#39;s say my laptop monitor id is A, I have an external monitor B on my 
desktop, but I also do presentations with projector C. 
 
First time I plug B, I configure it to work nice with A. kcm remembers 
this A+B conf. 
 
Later, I need to do a presentation. One hour before the presentation 
starts, I plug my laptop to projector C and configure this combination 
suitably for a presentation, say with cloned displays. I unplug from C. 
 
Time to give my presentation, I plug my laptop to C. kcm matches this 
A+C combination with the one I previously configured and restores the 
previous configuration =&gt; it just works. 
 
I am back to my desktop, I plug my laptop to my external monitor B. 
Again, kcm matches this A+B combination with a known one and set things 
up as they used to be. 
 
Extra bonus: two weeks later I give another presentation using C, I plug 
my laptop and I get the exact same configuration as the one I setup 
during my first presentation.
