After UpdateDeviceState, the device has the current position in absolute
coordinates, the event has the correct valuator data to be delivered to the
client.
This is better than the approach implemented with
8973a3f798 which disabled XI altogether for 1.x.
Instead, return a device list that resembles a traditional XI setup on pre XI
2.0 servers. If the client tries to open a device other than a floating SD,
return a BadDevice error.
Turns out some programs don't like this change. gnome-settings-daemon crashes
hard if you tell it that XI doesn't exist. So, tell them we have XI, but leave
the other change (the one that pretends no devices are available).
This reverts commit 8973a3f798.
Sorry. With the huge changes in the device handling I honestly don't know how
to support XI and XI2 alongside. So let's just pretend XI doesn't exist if a
client doesn't request it supporting XI2.
Remember the version the client sent to us, so we can adjust our replies
accordingly. This requires the client to use the {major|minor}Version fields
in the GetExtensionVersion request. However, they were padding before, so we
must assume they are garbage if nbytes is non-zero. If nbytes is zero, the
client is probably a new client and we can handle it correctly.
This variable was used originally to determine which client is allowed to
change the pointer-keyboard pairing. For now, we just let anyone change it and
see how that works out.
The previous check works in the master-branch, but doesn't work with MPX. We
actually copy the SD's information into the MDs public.devicePrivate, so we
need to explicitly check whether a device is a MD before freeing the module.
Basically the same approach RandR takes. Remember which one the client
requested, send back the one the server supports. Also divide XGE server
version (now defined in geext.c) and the client's version (still in the
protocol definition).
XKB was disabled in 08928afb05, with the comment
"Disable XKB, as we can't yet use it". Seems like "yet" is over, running GNOME
and changing XKB settings seems to work in Xnest now.
X.Org Bug 10015 <https://bugs.freedesktop.org/show_bug.cgi?id=10015>
I don't think this is the 100% correct answer as I get log spam saying
(EE) DoSwapInterval: cx = 0x98b8998, GLX screen = 0x96dd780
(EE) AIGLX: cx->pGlxScreen->swapInterval == NULL
but thats better than X exiting in my book.
