9e5c26690d45216629b5f588aced8fcfb68c23b6vboxsync# In order to keep things simple, we just call the X11 xrandr application
1c94c0a63ba68be1a7b2c640e70d7a06464e4fcavboxsync# when we receive notification of a display change instead of reimplementing
1c94c0a63ba68be1a7b2c640e70d7a06464e4fcavboxsync# it inside our Guest Additions client application. This saves us among
1c94c0a63ba68be1a7b2c640e70d7a06464e4fcavboxsync# other things having to find ways to build and link the C code on systems
1c94c0a63ba68be1a7b2c640e70d7a06464e4fcavboxsync# which do not support RandR 1.2. We wrap the call to xrandr in this script
9e5c26690d45216629b5f588aced8fcfb68c23b6vboxsync# so that we can make any fiddly adjustments to the call which may be needed.
