System-config-display, gnome-display-properties - inconsistent R5 U5 64bit

Question

Hi all,
I have OEL Rel 5 U5 (64-bit) installed and running on an IBM x3200 which has Radeon integrated graphics, with a IBM ThinkVision LCD monitor (1280x1024 max)
Problem I have is eventhough system-config-display lets me select 1280x1024 I can't actually get it to switch. Upon log-off/log-in, reboot, restart, etc... it still returns to 1024x768 mode.
Running gnome-display-properties only gives me a choice of 1024x768, 800x600, or 640x480.
I've also tried xrandr and trying to force it to 1280x1024 but it tells me I only have the 3 choices given by gnome-display-properties.
My xorg.conf file is configured with 1280x1024, 1024x768, and 800x600 modes, so I'm baffled at where gnome-display-properties and xrandr are getting their mode choices...
Can anyone shed some light on this?

Answer 1

Based on Xorg log I'm guessing the monitor driver just will not support the higher res and apparently that's where 'gnome-display-properties' gets its info regardless of what I try in Xorg.conf.
I'll see if I can manipulate the monitor settings and see where that gets me...
I see the following in the log:
