Comment 1 for bug 1586653

Problem is, that old nvidia drivers doesn't seems to be compatible with 3.19 kernel (there are some changes).

If you have black screen issue with it, try report it upstream and they maybe get get fixed. On #nouveau channel they could help you, if you can get dmesg.

To get screen output running, append in /boot/grub/grub.cfg to your actual kernel line nouveau.modeset=0 .

Also try experiment with later kernels, try 4.5.x, 4.6.x, 4.7.x and also you could try latest development 4.8_rc1
