Re: X windows and gdm on Dell/fedora

Two questions.

1) I'm having great problems getting a new Dell Dimension 8300 (newly isntalled
Fedora Core) to run X windows (gnome). It has a Nvidia GEForceFx 5200 card and
a Dell 1703 FPt flat panel monitor. When I try to run it I get a "Can't Display
This Mode" message.  I've changed the HorizSync and VertRefresh lines in the
XF86Config file to match those in the monitor's manual, but that didn't help.
I've also made sure the mode line matches the monitor's capabilities.

I only have the default (nv) driver for the card, but I think I'd get some kind
of image even with that. So far no luck. Can anyone help?

2) That brings up question 2:  how do I keep the system from trying to run gdm
on startup. I'm able get out of it by pressing ctrl-alt-backspace, but I have
to that repeatedly and it's very annoying. I've looked through the /etc/rc.d
directory but I can't see what's trying to run gdm.

thanks,

I am running a Nvidia card with a Sony flatpanel connected to the DVI interface. I get that message when I dont tell the nv driver to use the DVI output instead of the default VGA.

Here are the monitor and video sections from my XF86config file.

======================
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "SDM-X93"
DisplaySize 380 300
HorizSync 28.0 - 65.0
VertRefresh 57.0 - 63.0
Option "dpms"
EndSection

Section "Device"
       Identifier  "Videocard0"
       Driver      "nvidia"
       VendorName  "Videocard vendor"
       BoardName   "NVIDIA GeForce 4 (generic)"
       Option  "NoLogo"        "true"
       Option  "RenderAccel"   "true"
       Option  "ConnectedMonitor"      "DFP"
EndSection
=================

Here DFP tells the driver to use the Digtal Flat Panel. I didnt have to change anything with the HorizSync and VertRefresh, I'd just make sure they are within you monitors specs. You shouldnt have to mess with the mode line unless you are doing some funny resolution. I only had to do this with my Matrox Card on my Samsung DLP to get it to run at a native 1280x720 resolition.
