Default 24" Widescreen hassle with 9629 & 9742

Hi - both new driver versions 1.0.9629 & 1.0.9742 will only drive my Dell 2407WFP at 640x480 - Xorg.0.log describes all other modelines as 'invalid'

1.0.9625 & 1.0.9626 work fine.

you need to post a nvidia-bugreport or atleast your Xorg log file before anyone can help you.

This works for me with the attached xorg.conf file.

Default Re: 24" Widescreen hassle with 9629 & 9742

Hi - thank you very much indeed for this firsthand input from an experienced user: it appears my specific hassle was due to having disabled all the EDID functions in xorg.conf, in order to get the 1920x1200_60 +h/-v modeline working properly w/ 9625/9626 & a PCIe 6600.

. . now working with 1.0.9742 in Gentoo [Sabayon] 2.6.18 - relevant section from Xorg.0.log reads:

(II) Setting vga for screen 0.

(II) NVIDIA(0): Virtual screen size determined to be 1920 x 1200
(++) NVIDIA(0): DPI set to (96, 96); computed from -dpi X commandline option


. . note [crucially] the 1600x1200_60 mode has been validated, despite exceeding maxpixelclock.

FWIW, & if any other Dell 24" LCD user has the same sort of setup & hassles via DVI, I ended up with an xorg.conf reading:

Default Re: 24" Widescreen hassle with 9629 & 9742

Hi!
Your configuration example is a big improvement - at lest I get the intended resolution of 1920x 1200 now (Dell 2407WFP with FX5200 card).
But even with a short cable the quality is very bad:
- display image very unstable
- some periodic flickering noise
Is this graphic card sufficient for this display?
Any other hints?
Thank you very much in advance
W.
