26229df106 Don't init draglock, etc. if we don't have the required capabilities.
(cherry picked from commit 0f5a5ac09e)
2008-10-14 17:18:07 +10:30

f4616d87fc 8-bit properties should use 8-bit storage types...
(cherry picked from commit 36d68b006d)

2aa5ca8cdd Don't include the client-side header anymore. xkbstr.h is server SDK.

39263dc65d Tidy up evdev.h
This includes shuffling some functions around so we don't need the prototypes
in evdev.h.
(cherry picked from commit 0405f7b17f)

57521e4e60 Rename DragLockInit to DragLockPreInit, remove superfluous "return".

7da1522309 Register property handler from within the modules, not the main evdev file.
(cherry picked from commit cefedeb205)
2008-10-14 17:18:07 +10:30
Peter Hutterer
b4fcb825fc Clean up program flow - don't call PreInit for "modules" on DEVICE_INIT.
Call the PreInit functions for MB Emulation, wheel emu, and draglock during
PreInit, not on DEVICE_INIT. This way, we only parse the options once and
don't overwrite with defaults when coming back from a VT switch.
