    Display properties (resolution issue)


    Hi all,

    Installed RHEL 5 and found the resolution 1240x8... as the highest available resolution values. But I am able to increase the resolution not more than 1024x768 pixels. If I select, 1240x8... pixels and then "OK" a message will come like I have to restart the X window system to take effect for the changes made. I tried that and rebooting the machine as well. Nothing worked out and the resolution showed to 1024x768 as usual. Not able to increase more than this value even though 1240x8.. pixel value is available in the DISPLAY option.

    Motherboard : INTEL 865 GBF

    Suggestions and replies are appreciated.

    Tried replacing "i810" with "vesa" in the xorg.conf file and tried changing the resolution to more than 1024x768. But no change and the same problem persists.

    Please advice.
