There's a bit more info than this though. I think it has something to do with how gnome is handling an X windows session. I don't use graphical sessions a lot, but I seem to recall that when using them, tty0 is where GDM (the login screen) is displayed. After logging in to the windows manager, the desktop manager *replaced* GDM on tty0, and your session continued from there. Now, however, on Fedora 23, when I login to GDM on tty0, a new Xorg/GNOME session spawns on tty1, and the terminal switches there. At this point, the mini-toolbar dissapears. However, if I - F1, I go back to tty0, and GDM, and I see the mini-toolbar. If I then - F3, I go to a normal getty login prompt on tty2, and I can see the mini-toolbar. When I - F2, back to tty1, the mini-toolbar is missing. This may have something more to do with gnome than VBox, but I don't know much about how VBox handles switching between ttys. It could also be that I somehow misconfigured Xorg when I was trying to get acceleration working (or perhaps this is how 3D acceleration is handled)?
The app bar on the left has missing icons even the the name is there and the app can be run by clicking the blank space.The system button, that I believe should be on the top right next to my user name, is not accessible. My only shutdown option is to press my power button which brings up the shutdown options box.Many windows once open don't appear to have a minimise or close option.
