A constructor had lent a quadro FX1500 and FX3500 to me to test them.
Under a Red Hat EL4 with 1500 or 3500 with a LCD 30" barco + CRT 17", we want to make 2560x1600 + 1280x1024.
With Kernel 2.6.14 and xorg 6.9 and the last nvidia driver 9755 or all 9XXX, it's impossible to make a 1280x800 or more on a lcd screen DVI-dual-link. No error in the Xorg.0.log, we can "glimpse" the logo nvidia scrambled a tenth of second before a black screen.
I think that the problem is related to the dual-link, because we make a 1280x1024 with a DVI-D mono link on a old lcd samsung 24".
Note : With a quadro FX3450 under same condition, we make very easily 2560x1600 + 1280x1024.
We tryed with older driver (8762, 8774 and 8776) with 1500 or 3500, and we make very easily 2560x1600 + 1280x1024, but it's not stable :
- We start this X configuration, "x11perf -all" and return to console (Ctrl+Alt+F1) => Crash X
- it's the same in mono screen
The end of the Xorg.0.log :
