GF2 MX 400, cant go above 1026x768
1 Attachment(s)
I am using a Geforce 2 MX 400, running slackware 8.1. My problem is I can't get my resolutions to go above 1026x768. I know its possible because I can get to 1600x1200 in windows. Also I can't get itto run in 32 depth display(even with lower res set). Attached is my XF86Config-4

Modle: Geforce2 MX/MX 400
IRQ: 111
Video BIOS:
Card Type: AGP

In the Device section, add the line

Option "BandwidthTest" "0"

Section "Device"
Identifier "VESA Frameuffer"
Driver "nvidia"
Options "Bandwidth"Test" "0"
#Insert clock lines here

Doesn't work. What worked before skill works, but I still can't do a depth of 32 or above 1024x768 res.

well i don't know if it is another typo, but i noticed you have your irq at 111, and i know you meant 11, but you also typed "Options", and if this is what you actually used then, it is "Option" not plural..so if it is a typo and you did try Option, then i don't know what to tell ya

Both were typos in the posts. Real IRQ is 11 and I did do "Option" in my XF86Config-4. Thanks for pointing that out though.

If the bandwidth isn't it, you'll need to post /var/log/XFree86.0.log .

With the frequencies you set for your monitor (H 31-50, V 50-90) , you can not get much past 1024x768. Check your monitor's specs.

To get 1600x1200 the horizontal frequency must be ~80khz or greater. (careful, don't set these higher than your monitor can handle or you could damage/destroy the monitor!)

If you have gnuplot installed you might want to look at:
which is a script to plot the available modes for a given setup.

example: ./modeplot -b 185 -h 31 50 -v 50 90

(-b 185 is just an estimate for a monitor capable of 1600x1200)

The 'DEPTH, BITS PER PIXEL, AND PITCH' section of the driver's README addresses the second part of the question. (depending on how you read it :)
