i have been working on a twinview configuration for an mx440 with limited success.
currently my xorg.conf is:

Hi ... Have you tried turning Xinerama Off?

i should have mentioned that. it was originally not included, which i'm guessing is "off" then when i recompiled kde i thought i would try it "on" since i compiled in support but when that didn't work i tried it back and forth a few times without noticeable improvement.

after making that change it only displays on the left-hand monitor, but it does so at an appropriate resolution.
i did not think to mention it before, but both monitors are lcd's connected via vga. for this reason i believe they are to be listed as crt's but if this is incorrect it could be a problem.
thanks for your reply

it would seem i spoke too soon.
i disconnected the dual monitors after trying your suggestion and re-connected the crt i've been using until i get twinview working without changing xorg.conf back to the single monitor configuration, thinking that since it was displaying on only one monitor it wouldn't make any difference. i was wrong.
now the screen is spanning off the single crt, at an appropriate resolution, but will not display on a second monitor. additionally, the monitor connected to the vga port that does seem to be spanning now is on a kvm, i've no idea if this could make a difference for the configuration.

since my post a few minutes ago i have realized that i was using the wrong cable :oops:

, so, after straightening things out about which monitors i should be viewing, the spanning is working correctly across the wrong monitors. however, using the additional crt i mentioned above and the lcd that should be functioning as the right-side display all of the display is sent to the above-mentioned crt, just as before with the left-side lcd. i cannot recall verifying its, the right-side lcd, refresh rates and such, and it occurs to me to wonder if it would not display for this reason. i will endeavor to answer this myself but guidance is always appreciated.

i think what you want to do should be possible but i've yet to see anything to lead me to believe that it is.
my xorg.conf has both displays at the same resolution
