APM support in the Xserver was used to restore the console mode
prior to a power management event. This was to ensure the mode
upon suspend/resume was one that the system firmware or kernel
could deal with.
APM support is now largely obsolete, KMS drivers don't require a
mode restoration anyhow. Therefore it should be possible to disable
this feature.
(small modification by keithp - move test for XF86PM flag after check
for APM, then move XF86PM flag to xorg-config.h.in)

ProcessInputEvent() resets the device idle times. If idle time was higher than
the lower bracket, this should trigger an event in the idle time wakeup
handler.
If processing is slow, the idle time may advance past the lower bracket
between the reset and the time the BlockHandler is called. In that case, we'd
never schedule a wakeup to handle the event, causing us to randomly miss
events.
Ran tests with a neg transition trigger on 5ms with 200 repeats of the test
and it succeeded. Anything below that gets a bit tricky to make sure the
server sees the same idle time as the client usleeps for.

EDID sometimes lies about screen sizes. Since the screen size is used
by clients to determine the DPI a wrong ration will lead to terrible

DMPS calls dixSaveScreens() when turned off but not when turned
on. In most cases this is irrelevant as DPMS is done when a
key is hit in which case dixSaveScreens() will be called to
unblank anyhow. This isn't the case if we use xset (or the
DPMS extension directly) to unblank.
Check screenIsSaved to make sure the state needs to be changed
before calling dixSaveScreens().

The fb layer of X can't deal with strides that are not a multiple of
4, so when Xephyr allocates its own framebuffer it should make sure to
align it.
This fixes crashes and rendering corruption when Xephyr runs in a
depth that is different from the host X server and its screen size is
not a multiple of 4 / depth. (This is particularly easy to trigger if
you use the -resizeable option).

When the depth of the Xephyr server matches that of the host X server,
Xephyr simply uses the buffer associated with the XImage as its
framebuffer. In this case, it is correct to get the bits_per_pixel and
bytes_per_line values returned from hostx_screen_init() from the XImage.
However, when the depth doesn't match the host, Xephyr uses a private
framebuffer that is periodically copied to the XImage. In this case,
the returned values of bits_per_pixel and bytes_per_line should be
those of the private framebuffer, not those of the XImage.

Well, that was lame. The problem with reporting y inversion honestly is
that libGL asks the driver _its_ opinion of Y inversion, which it just
fabricates from whole cloth. So then when libGL goes to compare the
driver's idea of fbconfigs with that of the server - a fairly dumb idea
to begin with - nothing matches, and direct rendering fails, and
sadness.
So until the DRI drivers are fixed we should just continue to lie about
Y inversion. GLX_DONT_CARE is what libGL would make up for that
attribute if we hadn't sent it, so just send that instead.
