Setting screen resolution at login, RHEL5

[maxthedork]

Hi,

We have several Red Hat Enterprise Linux 5 servers (Dell PowerEdge 2950) and it seems the DRAC (Dell Remote Access Card) doesn't play well with resolutions above 800x600. If I log in as root and set the screen resolution at 800x600 then we can open the console via DRAC no problem. But when I log back out, the login screen displays at 1280x1024 and the DRAC says "Out of Range." I've been looking all over but I can't seem to find anything about setting the resolution on the login screen. Any ideas? I know there's got to be a way. (Also I set Modes in xorg.conf already, says "800x600" but makes no change... or does the server need to be rebooted?) Thanks in advance.

follow the advice here:

make sure that you are at RUNLEVEL 3 (init 3), ergo no X server running...

[-doublewide enable | disable]
[-doublehigh enable | disable]
[-outputs swapped | direct]

unknown :root: [4284]-> fbconfig -dev pfb0 -doublewide disable
unknown :root: [4285]-> fbconfig -dev pfb0a -doublewide disable
unknown :root: [4286]-> fbconfig -dev pfb0b -doublewide disable

This fixed the screen resolution issue with the left half of the screen showing
on the whole monitor and the right half of screen not on monitor at all.
