Lightdm logs as of when x11 has failed to start Xorg.0.log and dmesg output after X11 fails to start Malfunctioning boot while 5.0.22 additions are installed and shutdown via virtual terminal. Successful boot and shutdown with version 5.0.16 additions The other set reflects the botched boot up when the 5.0.22 guest additions are installed and me manually opening a virtual terminal to issue the shutdown command. One of them is a normal boot and shutdown while the version 5.0.16 guest additions are installed. The Ubuntu 16 VM was created by making a clone of the Ubuntu 15 VM within the Virtualbox manager and allowing the OS to upgrade to Ubuntu 16. Originally I just grabbed the generic Ubuntu 15.10 VM image from and installed some various packages mostly just related to building a cross-platform application that I program for. My host OS is Windows 7 Pro 圆4 and the affected guest OSs are Ubuntu 15.x and 16.04 LTS. (Edit (Michael): I am not aware of these "wide spread problems" at all, let alone able to reproduce them.) In that thread, Michael indicated Oracle can no longer can reproduce the wide spread problems where the newer versions of the guest additions (newer than 5.0.16) caused the video interface to not launch in some versions of Linux, so he asked me to open this ticket.



After a beta and four release candidates, VirtualBox 4.2.0 (stable) has been released today, bringing support to start VMs during system boot on Linux, experimental support for drag'n'drop from the host to Linux guests, improved Windows 8 support and more.
