Really there are a lot of questions I could ask, but the most basic questions I need to know are:
- Did you enable 3D Acceleration in the VirtualBox settings?
- Have you actually booted into the OS at all?
- If so, did you enable 3rd Party Device drivers?
Setting up and enabling the full graphics always seemed to be a bit of a process. I've used a few different virtual machine applications like VMWare Workstation, Sun VirtualBox, and Microsoft Virtual PC, and a huge array of Linux OS's in each of those (thanks to
DistroWatch). And many of those OS's I've run on my computer (including as a 2nd, 3rd, 4th, or even up to 5th OS). There are some of those that I could never get to boot at all, though Fedora, from memory, was always an easier one to get going. Including those that, as soon as I completed the process to setup Xorg, quit booting altogether, or would not pass the BASH prompt. This not even counting ensuring you have "Hardware/BIOS" settings all correctly setup for a Linux OS.
As far as I recall, after you install Fedora, and boot into the OS, you enable the 3rd party device driver, then enable/setup Xorg using an installer or program of some sort (should be in the OS menu somewhere), if you created an xorg.conf file (which I think you can also do) you need to ensure it's done correctly to your hardware, I have never personally created an xorg.conf, I've always used the built-in program that automatically creates that file. You may also have a bootline parameter you need to add, whether it be once or every time, or some other situation.
