Unhappy Can't increase display resolution higher than 800x600


I am new to Linux and I have just completed installation of Red Hat 9.0 Linux on a dual boot Dell machine. Even though the display setting shows display resolution of 800x600, it seems to default to 640x480 (as seen from the log file). I am not able to increase the resolution beyond the default. If I select a higher resolution, I receive the following error message:

I810(0): No Video BIOS modes for chosen depth.

My PC has an Intel 82865G Graphics controller, and I am using Dell 1901 FP monitor. The system uses i810 Display Driver for the controller.

I would like to use the resolution of 1280x1024, and Millions of Colors. What do I need to do to increase the screen resolution. Can I try using VESA driver or any other driver instead of i810.

I will appreciate any help.

Regards, Ravinder

Try manually changing the configuration in the XFConfig-4 file in /etc/X11/

Just open it with emacs or vi.

You can try running
at the console. Then select the driver and the resolution. I'm not sure if that is the command to use, because i haven't used red-hat in a while, now i use slackware and to configure x in slack10 you use

I have tried running redhat-config-xfree86, and also tried to edit the /etc/X11/XF86Config file. I do see higher modes in XF86 Config file, but the system defaults to 640x480 configuration, no matter what change I make in either case.

Looking at the XFree86.0.log, it appears to me that the system sees only 832 KB memory in the display adapter, although it has 16 MB memory. Hence, it always assigns the lowest resolution, as it thinks there is not enough memory for running higher modes.

Can someone suggest me what I should do next to fix the problem.

I was able to fix the display problem by installing a Diamond Stealth S60 AGP Video Adapter with 32 MB memory, as I had suspected that my integrated adapter with shared memory was not being recognized properly. The entire installation and setting-up process was pain-free. Now I am able to select 1280x1024 resolution (the highest supported by my monitor).
