177  *
178  * DISPLAY OWNERSHIP
179  *
180  * So, who owns the physical display and is allowed to write to it?
181  *
182  * In NT 5.x (Win2k/Win2k3), upon boot INBV/BootVid owns the display, unless
183  * /NOGUIBOOT has been specified in the boot command line. Later in the boot
184  * sequence, WIN32K.SYS opens the DISPLAY device. This open call ends up in
185  * VIDEOPRT.SYS. This component takes ownership of the display by calling
186  * InbvNotifyDisplayOwnershipLost() -- effectively telling INBV to release
187  * ownership of the display it previously had. From that moment on, the display
188  * is owned by that component and can be switched to graphics mode. The display
189  * is not supposed to return to text mode, except in case of a bugcheck.
190  * The bugcheck code calls InbvAcquireDisplayOwnership() so as to make INBV
191  * re-take display ownership, and calls back the function previously registered
192  * by VIDEOPRT.SYS with InbvNotifyDisplayOwnershipLost(). After the bugcheck,
193  * execution is halted. So, under NT, the only possible sequence of display
194  * modes is text mode -> graphics mode -> text mode (the latter hopefully
195  * happening very infrequently).
196  *
197  * In ReactOS things are a little bit different. We want to have a functional
198  * interactive text mode. We should be able to switch back and forth from
199  * text mode to graphics mode when a GUI app is started and then finished.
200  * Also, when the system bugchecks in graphics mode we want to switch back to
201  * text mode and show the bugcheck information. Last but not least, when using
202  * KDBG in /DEBUGPORT=SCREEN mode, breaking into the debugger would trigger a
203  * switch to text mode, and the user would expect that by continuing execution
204  * a switch back to graphics mode is done.
