> Do you mean one desktop split over two separate displays? Not that I can help, as I only have one display at a time.



No. I have a 1920x1080i timing mode from Jarrod that I was using with so-so results before the upgrade. Now, I still have a 1080i mode, but what is supposed to be on the left of the screen is on the right, and vice versa. I'll try to illustrate in text:

What I should see:

ABCDEFGHIJKLMNOPQRSTUVWXYZ
ABCDEFGHIJKLMNOPQRSTUVWXYZ
ABCDEFGHIJKLMNOPQRSTUVWXYZ
ABCDEFGHIJKLMNOPQRSTUVWXYZ
ABCDEFGHIJKLMNOPQRSTUVWXYZ
ABCDEFGHIJKLMNOPQRSTUVWXYZ

What I do see:

NOPQRSTUVWXYZ_ABCDEFGHIJKLM
NOPQRSTUVWXYZ_ABCDEFGHIJKLM
NOPQRSTUVWXYZ_ABCDEFGHIJKLM
NOPQRSTUVWXYZ_ABCDEFGHIJKLM
NOPQRSTUVWXYZ_ABCDEFGHIJKLM
NOPQRSTUVWXYZ_ABCDEFGHIJKLM

The _'s indicate a vertical white bar. Actually, I am probably missing about the N and M portions as well from overscan. My set can adjust it, but it really warps the screen adjusting too much out this way.

This is the modeline:

ModeLine "1760x960" 74.5 1760 1888 2096 2208 960 1012 1028 1126 -hsync -vsync interlace

It is fed through an AudioAuthority transcoder to the component inputs on my Samsung widescreen.

Hope that explains the problem better.

Some further info:

I reinstalled from scratch today, wiping everything but my /video partition. Followed Jarod's guide all the way up to the 7174 nvidia drivers, with just a monitor attached, no transcoder or TV, and using Jarod's xorg.conf unaltered. The same thing happens with the monitor. Furthermore, the other two modes in that modeline result in a virtual desktop. This did not happen with the 6629 drivers. I'm at a loss, and have no easy way to get back to a working setup until I figure out the problem.

Digging around on Google, I can't find any references to anyone else with this problem. I'll have to dig further, it seems.

Jeff.
