Fedora 20 User Switching EVGA GeForce GTX 760 Black Screen Mouse Cursor

When I enable the Nidia 331.38 NVidia driver on a Fedora 20 system and attempt to “switch users” to an already running GNOME/X sessions, the only thing that I see is a black screen with a mouse pointer. I’ve run the Nouveau driver and have been able to switch between users without a problem. Has anyone else run into this? I’d hate to have to keep uninstalling the NVidia driver when I want to do normal computing and reinstalling it when I want to play games. :-(

Plz provide nvidia bug report by running nvidia-bug-report.sh as root user.

Okay. I will when I have the time.

Internal bug 1459061 to track this issue.

Okay. I have attached an nvidia-bug-report.log file.

Actually, after trying to reproduce the problem again and discovering whether I could coax the system out of the black-screen-with-mouse-cursor state, something prompted me to try pressing random keys. Well, the first key that I pressed, which I hadn’t tried previously, was the “Windows” key, which normally places the screen in applications preview mode. To my delight, the screen suddenly appeared! Yay! That’s the only key that made the screen content show. I’m kicking myself for not trying that before but I pressed random keys previously and nothing happened. Obviously, I had been pressing the wrong keys.

I don’t recall having to press the Windows key to make the screen reappear while using the Nouveau driver. I think that I just had to move the mouse or press any key. Nevertheless, pressing the Windows key is an easy thing to do to make the screen reappear. The question is why doesn’t the screen reappear automatically when I switch to an active session.

can you try the fixed version of Gnome shell from this external bug: https://bugzilla.gnome.org/show_bug.cgi?id=703174

You need to use fixed version of Gnome shell and test. I think patches are:
