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).

Well, there is nothing wrong with any of the hardware. I can get full UHD resolution with Windows 7 and the nvidia drivers, so it is now officially a research project for linux :-(.

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.

I have a feeling this is going to have something to do with the nvidia.com driver version being at 337.25 and the latest version in rpmfusion being 331.something
I think the ubuntu proprietary repos have newer versions, so I'll give ubuntu a try and maybe I'll get some version of linux with full support (I'd hate to have to be forced to run Windows just to use my monitor).
