Created attachment 1225478 [details] kernel messages Description of problem: nouveau results in a black screen when 3 monitors are connected to a Quadro K2000 at boot time. If I boot with only two monitors connected and plug the third one in on-the-fly everything works fine but on next reboot the problem occurs again. It *seems* like it's driving the monitors at the wrong frequency but I can't tell for sure. kernel version: kernel-4.8.8-300.fc25.x86_64 device is: 05:00.0 VGA compatible controller: NVIDIA Corporation GK107GL [Quadro K2000] (rev a1) (prog-if 00 [VGA controller]) When the black screen occurs, the attached nouveau.txt file contains the kernel messages.
