I've just had to re-install WinXP on VirtualBox, which in turn is running on Fedora 15. (I just haven't had time to upgrade Fedora yet.) VB is currently set to use 512MB RAM and 10GB HDD.
The problem is that I can't get it to switch to full screen mode. When I select this option from VB's File menu, all that happens is that the KDE desktop disappears, leaving a standard sized VB window/desktop surrounded by a large black border all around.
If I again re-install VB and set the RAM to 1GB, would that fix the problem ? As for the graphics card, its a GeForce FX5200 with 256MB on-board memory which is being used with the Nouveau driver.. I don't suspect either of these to be the problem as they work fine in other programs.
I really do want to get the best out of this VB/XP setup so any help that can be given would be very much appreciated.
