start X with smaller default-resolution ?

Does anyone know a way to start X with another than the maximum resolution given in xorg.conf for a screen ?

Background :
- my physical Display is 1280x720. (a 16:9 - TV-TFT)
- for some applications I need a bigger virtual resolution (i.e.: 1024x1280)

Yes I can change resolution at runtime using kde-settings or xrandr but it would be nicer if X would already run with 1280x720 while entering runlevel 5 and displaying the login-screen.

Thanks for your hint.

Are you sure you know what resolutions you are using and need?

There is no 1280x720 or 1024x1280. And on a 16x9... What kind of monitor is this? 16x9 would be widescreen, so you wouldn't want 1280x1024 or 1024x768... you would want something closer to 1440x900 assuming it is a fairly big monitor.

Yes, I have 2 working modelines for one screen in xorg.conf:

(1) 1280x720 : this is the physical resolution of my 16:9 widescreen
(2) 1280x1024 : this is a virtual resolution (which means that the visible area is moved as the mouse hits the vertical borders)

I would like to start X with (1) i.e. in a smaller than maximum resolution before launching a usersession.

unfortunately xorg.conf or X - commandline-Options do not allow me to specify a default modeline or colordepth...

The only thing I could specify is a screenlayout - but here I did not find a way to change it during runtime.
