xrandr does not find modes defined in xorg.conf

[Nils]

Hi all

I have a strange problem on a T43p Laptop with Edgy on it. When I
execute xrandr --query, it only shows the current resolution, but not
these in xorg.conf. I'm not sure where xrandr gets the resultions
from, but I don't think it's xorg.conf.

Another problem i have is that i cannot change the resolutions with
ctrl-alt-+/-. I'm not sure if KDE is blocking or if it's a problem if
the +/- is not on a numeric keypad (since it's a laptop..).

Thanks for comments and suggestions.
