Last change on this file since 60133 was 60133, checked in by vboxsync, 9 years ago

bugref:8288: Additions/x11: rework VBoxClient video mode hint handling: remove explicit ACPI code and left-over Vbgl calls in the user space graphics driver. We probe for screen changes on every X server wake-up, and the X server wakes up on ACPI events even without our handler.
