This question already has an answer here:

I have two DVI outputs on GTX 750 NVidia card on my desktop running Ubuntu 14.04. One DVI works fine, the other doesn't seem to be working at all.

Monitor connected to second DVI can't register any signal. Cable I am using to connect it is OK, checked on different installations, driver is the latest (3.40\3.46).

Reinstalling drivers or changing xorg.conf manually didn't help.

Is it possible to configure two DVI ports on GTX 750 with Ubuntu 14.*?
