I have an Asus M2NPV-VM motherboard with integrated NVIDIA GeForce 6150

I booted in recovery mode and ran:

      # Xorg -configure

which created /root/xorg.conf.new.  But when I try to use that file, X
hangs when starting.

I have used the proprietary NVIDIA driver in the past, but would like to
use the free Debian drivers instead.

1.  I can determine the current resolution and refresh via Start ->
System ->  Preferences ->  Monitors, but I cannot change those settings.

2.  How do I determine the current color depth (e.g. 8/16/24 bits per

3.  How do I change the display settings -- resolution, refresh, color
I recommend to use a more or less classical xorg.conf. I'm still using
CRTs myself.

Depending to the used card, I get different options to set up different
resolutions and frequencies by the Xfce GUI, with equal settings for the
monitor. There are more choices for my NVIDIA card. However usually I
need 1152x864 at a much higher rate than even 70Hz, currently it's 90Hz
and that's ok.

Useful information would be the vendor and model of your monitor and
your xorg.conf.

Last time I had trouble with monitor resolutions, I dealt with it using `xrandr'.
