change display resolution Centos 5

Hi,

I'm wondering how I can the display resolution on my Centos 5. The screen is stretched. I went to System->Administration->Display and then changed it from 1152x864 to 1920x1200. It states to logoff and then login. But nothing happened and the res is still 1152x864. How can I change this? I haven't rebooted yet though.

Thank you,
Vkimura

It didn't work.

I have this in my xorg.conf:
[root@seokingdomheaven X11]# cat xorg.conf
# Xorg configuration created by system-config-display

Section "ServerLayout"
        Identifier     "single head configuration"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us"
EndSection

Section "Device"
        Identifier  "Videocard0"
        Driver      "r500"
EndSection

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


In System->Preferences->Screen Resolution I have a maximum resolution of 1152x864. But System->Administration->Display I have a max of 1920x1200.

Hi Jay,

The first time I tried to run in terminal but I think your mentioning some GUI session and some other console. Where do I run that command? How do I get to that console?

Thank you,
Victor

Happy New Year btw,

Thanks. I was just looking into the onboard video chipset that I have:
Motherboard: Gigabyte Technology Co., Ltd.
Product Name: GA-MA78GM-US2H

Based on AMD 780G chipset, GA-MA78GM-US2H is integrated ATI Radeon HD 3200 (DX10) graphics engine and supports AMD Phenom...

I'm using a VGA cable. I just read this on a forum:
The HD 3200 will support 2048x1153 on the DVI port just fine

Didn't know DVI supports higher resolution. Do you think that will resolve the problem? If I get a DVI cable?
