How to set resolution and refresh rate for user shared workstation
 

OS version:
Red Hat Enterprise Linux Server release 5.3 (Tikanga)

User Request:
"We need to set the resolution to 1280 X 1024 and the refresh rate to 60 Hz. There are two monitors"

Note: each user can change the settings, but settings are lost when they logout (they are not root).

User states resolution and refresh rate can be set but it's not the default (settings lost after logoff).

Question:
How can I set a default resolution (1280x1024) and refresh rate (60 Hz) remotely so all users don't have to set every time they login. This box is dedicated to 1 function and i have root access remotely but not the desktop gui.

/sbin/lspci | grep -i vga
