I'm hosting Linux on Linux, with two screens. When I boot, the primary monitor doesn't draw correctly, and the guest uses the 2ndary monitor as the primary. When I full-screen, the VM aborts. Sometimes, both monitors respond to mouse clicks. Sometimes, when the windows are not full-screen, they draw correctly. I've tried the up to date OSE and Oracle versions of Vbox and guest additions. I've also tried different versions of the Nvidia and Nouveau video drivers on my host and get the same results. I've also treid with/without 3d acceleration. Here's a log from a crash: http://pastebin.com/rR8b6dpZ If that isn't enough, what's the best way to debug this? It's easy to reproduce. Any suggestions? Thanks!" defect closed other VirtualBox 4.1.22 invalid multiple screens crash Linux Linux
