Last change on this file since 60050 was 59943, checked in by vboxsync, 9 years ago

bugref:8087: Additions/x11: support non-root X server: revert r105407: do not start the display part of VBoxClient at all when not using the user space X.Org vboxvideo driver: all guest systems capable of running the kernel driver should already have equivalent functionality.
