I'm trying to install Xubuntu 14.10 (tried 15.04 beta1 as well) in a VirtualBox (4.3.24) VM. The VM boots from the ISO, and when I let it boot to the live mode or select "install", it tries to come up into the graphical installer and hangs with a resized window which is long and narrow.
Any ideas?
This http://ubuntuforums.org/showthread.php?t=2250037 solution worked for me.
Preferences + efi.
Some vdi images can also be downloaded, but that bybass the difficulty.
