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.

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.

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.




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:

waiting for X server to shut down .

OK, Monitor working fine. Path and permissions issue with GDM. Now my second problem that I listed in the beginning, I am unable to run gdmsetup. gdmsetup:4406 Gtk-WARNING ** Cannot open display -- Any ideas? Thanks so much for your help.

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.

Still unable to run gdmsetup.
I get Gtk-Warning **: cannot open display
I am now setting DISPLAY env variable = :0.0
Still have same problem.
Even when I run xhost + I get "unable to open display :0.0"

Any thoughts?

Thanks
