Is nouveau supposed support DisplayPort output as of Linux 4.1? I have an EVGA GeForce GTX 750 Ti. TMDS outputs (HDMI/DVI) works while DisplayPort output failed and delays initialization of nouveau. It seems that nouveau failed to read EDID properly through DisplayPort as well. The following are grep'd kernel messages of booting with DP/DP+DVI/DVI connected respectively:
