Currently, when main hardware screen is powered-off,
X server initializes fake screen's timer with
1 second update interval.
Streaming software like Nomachine or Vnc, as well as
desktop input automation suffers from it, since it
will forever be stuck on 1 fps until the display is
turned back on.
This commit adds command line option -fakescreenfps <int>
that allows the user to change the default fake screen
timer.

Since crtc can belong to secondary output that may not have present
extension enabled we should fallback to first enabled crtc or fake crtc.
Fix for issue xorg/xserver#1195
This will allow eliminating indirections and making the Xwayland Present
code more efficient and easier to follow.
While this technically changes the Xorg video driver ABI, I don't know
of any drivers using the dropped present_wnmd_* symbols, and I doubt a
Xorg driver could make use of them as is anyway.
(As a bonus, Xorg no longer links any Xwayland specific Present code)
v2:
* Wrap DestroyWindow before initializing Present, so that
present_destroy_window runs before xwl_present_cleanup. Avoids crash
due to present_destroy_window calling xwl_present_* functions when
xwl_present_window was already freed. (Olivier Fourdan)

It always takes one update cycle for the copy to become visible on the

For Pixmap flips to have well defined outcomes the window must be contained by
the valid region if such region was specified.
The valid region is inserted as an argument to the check in window mode.
Setting this argument is missing in screen mode as well but we ignore it for now
and only add it to window mode.
It seems there are none or only very few clients actually making use of valid
regions at the moment. For simplicity we therefore just check if a valid region
was set by the client and in this case do never flip, independently of the
window being contained by the region or not.

The function is never called from present_screen.c in contrast to the behavior

With the newly introduced separate API method for idling a presented Pixmap in
window mode we can simplify the logic by allowing calls to it at any point in

Notifying Present about events' states was done prior with the single function
present_wnmd_event_notify just like in screen mode. But it is more intelligible
if at least in window mode we make use of three different functions with names
that directly indicate what their purpose is:
* present_wnmd_event_notify only for queued events feedback.
* present_wnmd_flip_notify for when a presentation occured (flip).
* present_wnmd_idle_notify for when the Pixmap of the event can be reused.
This is an API-breaking change in regards to window mode. DDX written against
the previous version won't work anymore. It is assumed that there only exists
the XWayland DDX at the moment using the window mode such that this is not an
issue for the overall ecosystem.

When present_wnmd_clear_window_flip is done, present_destroy_window
frees struct present_window_priv, and the events in the flip queue
become unreachable. So if we don't free them first, they're leaked.
Also drop the call to present_wnmd_set_abort_flip, which just sets a
flag in struct present_window_priv and thus can't have any observable
effect after present_destroy_window.

Currently, the function `present_wnmd_abort_vblank()` would fail if the

However, `xwl_present_get_crtc()` can return `NULL` under some
circumstances, which would cause an unexpected termination of Xwayland
in such a case, caused by the assertion failure being triggered.
Remove the assertion, considering that the `crtc` isn't actually used in
