Default [Fixed] 1680x1050 GeForce 6600GT DVI 1.9746

Hi!

Today I installed ubuntu on my workstation (which previously was running gentoo) and now I'm unable to make my 20" Acer widescreen monitor at its native resolution (1680x1050) through DVI. I have tried everything, from all the options in ModeValidation (where 1680x1050 gets filtered out in X log), telling the driver not to use EDID, generating modelines, etc.

My card reports by nv driver hsize 1680 vsize1050 refres: 60 vid:179. However it always falls back to 1280x1024 resolution which looks kinda crappy on my monitor. I wondered if there is a way I can get it to work once again.

Thanks in advance.

PD: I used de 9xxx beta drivers in Gentoo with a Modeline that looked like this:
Modeline "1680x1050@60" 154.20 1680 1715 2296 2328 1050 1071 1081 1103

Please start X with the following command:
startx -- -logverbose 6

and then generate and attach an nvidia-bug-report.log.

thanks,
Lonni

This bug report was not generated after running the command I provided.

Please try adding the following options to the Device section of xorg.conf:
Option "ModeValidation" "NoDFPNativeResolutionCheck"
Option "ExactModeTimingsDVI" "true"

Thanks,

Thank you very much, it finally worked. I think when I tried all the modevalidation options I skipped this one :P .

Well Fixed then!!!
