Question Multiple screen profiles? / auto detect monitors

1) Is there a way to save different screen profiles?

I have a laptop, 24 inch monitor and a TV. At home I use the 24" as my main monitor and the TV is hooked up for movies, but when I'm at school etc. I only use the laptop dispaly.

When I come home I then need to open nvidia-settings and configure everything each time. So I'm looking for a way to store my setups in such a way that I just pick the setup I want when I need it.

2) Is someone working on a auto detect / auto setup feature?

It would be awesome if monitors automatically got configured and enabled when you connect it to the machine. Something like what happens in Mac OS.

Default Re: Multiple screen profiles? / auto detect monitors

Hi!
I've been working on something like this. It doesn't detect when a monitor is being plugged in, but when the program is called it detects the displays and sets them up accordingly; there is also an import/export feature for storing the current configuration (e.g. after tweaking with nvidia-settings) and restoring that.
TV-out doesn't really work right now though.
I hope that you can find most of what you want in disper:

Thanks for the reply!

Disper looks very promising, worked right out of the box. But I have a problem with the nvidia driver it self I think. Nvidia-settings doesn't list the right resolutions, and it even changes from time to time. I connected and old 19" CRT display just to test disper and here's what happend:

The first run:

Code:
me@laptop:~$ disper -l
display DFP-0: LCD
 resolutions: 320x240, 400x300, 512x384, 576x432, 680x384, 640x480, 720x450, 640x512, 700x525, 800x512, 840x525, 800x600, 960x540, 1024x768, 1280x800
display CRT-0: CRT-0
 resolutions: 320x240, 400x300, 512x384, 680x384, 640x480, 800x600, 1024x768, 1152x864, 1360x768
As you can see I get alot of different resolutions to chooe from, but I don't get the display max resolution which is 1280x1024.

Then the second run:

Code:
me@laptop:~$ disper -l
display DFP-0: LCD
 resolutions: 320x240, 400x300, 512x384, 576x432, 680x384, 640x480, 720x450, 640x512, 700x525, 800x512, 840x525, 800x600, 960x540, 1024x768, 1280x800
display CRT-0: CRT-0
 resolutions: 320x240, 640x480
Same results can be found if I open nvidia-settings.

Any ideas why this happens?

You could use the Xorg option to override the display's EDID if you don't switch monitors often; you could read the EDID using nvidia-settings when it is returned correctly and reference that in your Xorg.conf.
