screen reso refuses to change

i am running redhat 9.0 on one of my boxes and changed moniters recently. the old settings were small and smaller :) i am try to use "1024x768" "1152x864". I tried using redhats display manager and when i hit ok nothing happens i also opened xfree and added these to mode but when i hit alt ctl + or - it only changes back and forth between the lower settings. any ideas?

here is the error using redhat-config-xfree86

Traceback (most recent call last):
File "/usr/share/redhat-config-xfree86/xConfigDialog.py", line 229, in ok
adj.scrnum = 0
AttributeError: No such attribute

post your XF86Config. sounds like there is an error for the monitor settings (the scrnum 0 means first screen or screen 0)

are you really using an ATI Mach64 video card, and does it really only have 4 mb of ram on it?

also is the Mode 0666 option really uncommented in the DRI section or did you just miss the hash mark there.

If you really only have 4 megs of vram, I'll bet 800x640 is as high as you'll get at 24 bit color.

also try placing the 1024x768 and 1152x864 modes in FRONT of the other listed modes in order. Don't know if that matters or not.
