1440x900 using an Intel 810 on Xorg
 

I've been trying to get 1440x900 resolution working on an Intel 82915G/GV/910GL chipset.

I would also like 32 bit colour.

I'm stuck at the moment using Xorg on Slackware.

I can only get 1280x1024 but no widescreen.

Thanks

You might try using the "gtf" program to generate a modeline.
This example is for your stated resolution, at a 60 hz refresh rate.
Make sure that your monitor can handle this resolution. Also, you won't get more colors using 32 bit over 24 bit. The extra bits are for overlay information, which you may not be using.

The gtf program, "General Timing Formula", is a part of your xorg installation, so you should have it already.

Thanks for the quick reply.

I did that in windows using powerstrip:

This came out:

"1440x900" 106.560 1440 1520 1672 1904 900 903 909 934 -hsync +vsync

I did run it but the widescreen was not treated properly by the monitor...
Will try again

Try the "gtf" program when the system isn't loaded down.

Also, check if you have "UseModes" in the "Monitor" section. This example fragment illustrates this:

Section "Modes"
