First, let me apologize if this has already been asked and answered, but after doing several searches, I didn't come across it.
I have upgraded to Gnome 3, and I do use systemd. The problem is that after I login using gdm as my user, I get the blue background, and the gnome environment for maybe 3 seconds, and then the screen goes blank/black. I can still see the mouse pointer, and I can still move the mouse, but right clicking doesn't bring up a menu.
If I login as root, everything is fine. The session starts, and remains active. In fact, I'm writing this post while logged in as root.
If I manually execute /usr/bin/gnome-session as my user from the console, gnome starts, and remains active, but it doesn't show any applications, so starting it this way is useless. Besides, I would really like to be able to have a functioning session as my user by logging in through gdm.
I've had this problem for about 2 weeks now, and I had been hoping that some update would magically fix this, but it has not. If I need to post some configuration files in order to get help debugging this issue, please let me know which files, and I will gladly do so. I just can't figure out what's different for root v. my user. I have an Nvidia video card, but I can't see how I would've configured it differently for user v. root.
Thanks in advance for the help.
