Xauthority, modify the permissions, file files are modified, the results are not all eggs, so upgrade the virtual machine version, upgrade to 4.2.12, no, continue to upgrade 4.3.8, no, then upgrade the virtual machine error, the high version is not very stable, can only be loaded back 4.3.8. System changed to 15.04, still not. Finally, is it because the lower version of the software enhancement package does not support the new version of Linux? But can not install the high version of the virtual machine, so dead horse when live horse medicine, to the new version of the VirtualBox directory under the latest version of the VBoxGuestAdditions5.04, installed, feasible, the problem also solved.
