Smile Gnome and Dell M992 Display-Unable to increase resolution


Hi, I am very new so please bear with me.

I have tried searching through the forums but I am stuck.
I am running Oracle Linux 5 with is derived from Redhat.
When I run startx from the root prompt, my resolution will not go smaller than 800 X 600.
I am using Gnome.
I run system-config-display and when I try to set a better resolution, nothing comes up on the screen.
I have a Dell M992 19" Monitor
My video card is Integrated Intel 3D AGP (82845G/GL [Brookdale-G] GE Chipset Integrated Graphics

In addition, I am unable to open a login screen within Gnome.

Do i need to buy a new video card and if so, will it work with my Dell monitor M992?

I don't have a lot of time, but first DON'T run as root, run xserver as user and if you need anything done as root su or sudo for root privlages.

Do a search on configuring your xorg.conf it's located in /etc/X11/ directory.

I or someone will get back with you I'm sure latter.

Xorg configuration

Ok, no more root work, su only.

Xorg config:

# Xorg configuration created by system-config-display

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "i810"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "800x600" "640x480"
EndSubSection
EndSection

Ok if you are wanting a higher resolution edit your xorg.conf file as root, and edit your modes section. Add the resolution you want to be default on boot up to the left as I have here.

Code:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection
The Bash shell reads from left to right. Also edit the monitor section and add the right Horz and Vert for your monitor, like so.



Code:
Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        HorizSync       30-83
        VertRefresh     56-75
EndSection

Then the next time you startx you will have a higher res.

Hi, made those changes to xorg.conf and still have the same problem. Maybe I have a bad video device??

** New things I noticed. When I close the X Term session, I get the following messages:

Unable to open desktop file
/usr/share/applications/openoffice.org-1.9-writer.desktop
for panel launcher: No such file or directory

Unable to open desktop file
/usr/share/applications/openoffice.org-1.9-impress.desktop

Unable to open desktop file

is a bug in the application.

Window manager warning: Got a request to focus the no_focus_window with a timestamp of 0. This shouldn't
happen!

waiting for X server to shut down .

I am going to go back into xorg.conf and change the monitor section back to what it was originally, now that my path and permissions are ok. I will get this done tonight, so I will update this post around 7PM ET. Mar 4 2008.
