+This file contains some notes about things to try out to give the X.Org video
+driver a reasonably thorough test. We will add cases of things which have been
+known to fail in the past to this file as we discover them. Tests should be
+carried out with Additions installed, and both with and without 3D enabled in
+the machine settings.
+
+ * Test XFree86 guests (CentOS 3), early X.Org (CentOS 5) and recent
+ (CentOS 6 and 7, current Ubuntu/Fedora). Test Solaris guests (10 and 11?).
+ * Dynamic resizing should work, on CentOS 6 and later Linux guests it should
+ work without VBoxClient running.
+ * Disabling and enabling virtual screens (VBoxManage in 4.3).
+ * Dynamic resizing with one of more virtual screens disabled.
+ * Test switching to virtual terminals and back from windowed, full screen and
+ seamless modes (seamless currently only works properly with VBoxClient
+ running).
+ * Test switching directly between normal, full-screen, seamless and scaled
+ modes.
+ * Test re-ordering the virtual screen using the native guest operating system
+ tools and make sure that mouse integration still works as expected.
+ * Test disabling and re-enabling guest screens with the native system tools.
+ * Try disabling and re-enabling mouse integration and check that capturing
+ works with multiple guest screens.
+ * Shutting down and re-starting a virtual machine should restore the last size
+ for all monitors (note: currently only after log-in). Full shut-down, not
+ a reboot.
+ * Test power management by disabling guest screens ("xrandr --output VGA-n
+ --off") and re-enabling them ("xrandr --output VGA-n --preferred --pos XxY")
+ where X and Y are the position of the screen before disabling it.
+ * Test sending video mode hints with screen position information via
+ VBoxManage. The screen position is a hint only. The approximate position
+ should be preserved after a shut down and re-start of the guest.
+ * Test re-starting the X server after resizing all guest windows. The server
+ should not crash.
