Display settings strange behavious

[Peter Lauri]

Hi,

I have a Thinkpad T43 and just purchased a new ThinkVision monitor.
All works find out of the box if I startx in the root account. But if
I do the same thing with a normal user account the resolution is not
put to the native resolution (1600x1200). If I try to set it via the
display config tool, and restart X server I cannot login anymore. And
when I reboot the computer, the lower resolution is back in the
settings.

It feels like that the user don't have permissions to setup its
display preference. But I don't know where to start to look.

Any hints why root can get proper display settings but not a normal user.
