In my quest for more pixels, I'm trying to get my new UHD monitor working in 3840x2160 resolution. The nouveau driver doesn't know how to drive the GTX 750Ti card, so I had to install the nvidia binary drivers from rpmfusion. At this point, everything seems to work except for the one minor detail that the screen is always black :-). X thinks it is up and running, the Xorg log file shows it recognizing the video card and selecting 3840x2160 resolution. Nothing that seems like an error appears anywhere I've looked. I just have that black screen problem (Ctrl-Alt-F2 does get me to a console, so it works fine in console mode - it also worked in 1920x1080 mode on a different video source that couldn't support UHD resolution). Does any of this sound familiar to anyone? (I'm off to try stuff like a different cable in the hope that it is something dumb).
It sounds a little like the black windows/pop-ups/dialog boxes I kept getting ever since I took an upgrade during the F17 cycle. But when I installed F20 on a new machine and migrated to it, I did not get that problem.
