Thumbs down screen resolution, how to get higher, RHE5


Is there any way to change screen resolution in RHel5 to 1280x1024?
This is from xorg.conf:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

It does not recognize the command "Modes"!

You need to provide a bit more information, like which video card you have and/or all of the /etc/X11/xorg.conf file.

You can try as root running at runlevel 3 the following command;

system-config-display --reconfig --set-resolution=1280x1024

well, the highest that's awailable is only: 1152x864

Section "Monitor"
Identifier "Monitor0"
ModelName "Sony Multiscan 20se"
### Comment all HorizSync and VertSync values to use DDC:
HorizSync 31.5 - 85.0
VertRefresh 50.0 - 150.0
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "nv"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

I know it can run much higher since this system was previously running windows.
Also, my son could play games on it but now with the just Linux OS it is slugish and it acts like it does not have enough RAM. It has problems to redraw.

Try again runing the system-config-display command, this time leave off the set-resolution portion.

Or try setting the resolution to 1152x864 using the system-config-display command.

Or follow the advice given(edited example);

Driver "nv"
Or try using the nVidia drivers instead: http://www.nvidia.com/Download/index.aspx?lang=en-us

Exclamation Ubuntu can! RH cannot!?

I did commented out the two lines about the refresh rate but it did not help.
I looked under video card configuration and I can see why. This is what it states:
nv - nVidia Riva 128, RIVA TNT, GeForce, nForce, and QUADRO cards
So, it does not support more memory. Also, the company does not support this card for Linux any higher than it is.

What would be an appropriate card that would support proper video workings? High resolution and fast responce or redraw!
//+++++++++++++++++++++++
One thing!: during my installation process, due to conflicts, I had installed UBUNTU to test it and it does support much higher resolution, beyond 1280x1024, how's that possible!? And it was responsive as well, no problems!
There must be something else if Ubuntu can do it so RH should be able to do.

Try a lower the resolution depth;

system-cofig-display --reconfig --set-depth=16 --set-driver=nv

See for more options: system-config-display --help

FYI: I know you have one in networking, I've posted replies.

After screwing with that a bit like you said it generated the values that allowed me to input the values that I wanted and it works now!
Thanks!
