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.

* 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.

* execute "xprop -root | grep VBOX" after resizing a screen: VBOX_SIZE_HINTS

should be set, and VBOX_SIZE_HINTS_MISMATCH should equal 0 on CentOS 6 and

later (4.4 and later).

* 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.
