Hi – I tried the prepackaged vdi from Virtualbox and liked what I saw. I downloaded Core from here and booted from a usb drive. Saw no errors after log there is a long wait until graphics appear. Up to this point I could move the mouse with my touchpad. Then a windows show up and before I get a chance to do anything it immediately starts up the screen saver. Hitting enter brings up the login screen. At some point as I was trying different keys, makulu showed up as the username. I clicking on the username or password field did nothing. If I hit enter the screen saver pops back up.
