Hi

just installed UB 8.04

i have a Nvidia Geforce 6800 Ultra 256 mb card
2 NEC MultiSync LCD1760NX monitors one on DVI digital and one on DVI analog.. (different cables!)

i want to run them both at the same time (dualhead?)

but!

i install the latest drivers that Ubuntu takes down for me.. and install, restarts and the Nvidia logo shows on both screens, at first they run in 640*480,and i cant find where to install and configure the screens, so do some "foruming" and finds a comand


sudo displayconfig-gtk

runs it and finds that is the same thing i have been looking for (it used to be visible in UB 7.10 why did the hide it???)

so anywhay..

i did install the right monitors (i think) and restarted, and well the resolution went up, but now its the "virtual" size greater than the screens native resolution that is selected, so i have to scroll at the end of the screen every time i want to do something..

here is my Xconfig if any one would pleas take a look i would gladly appreciate it

(ps i did change one thing in the X.. and that is the ...
