Description Peter Hutterer 2012-10-30 00:49:02 UTC

Touch pointer emulation on the root window does not work correctly.

Simple test case, both on a plain X server:
xev, tap into xev window, events registered are Motion, ButtonPress, ButtonRelease (plus optional motions in between)

xev -root, tap on root window, only a MotionNotify is seen, no button events.

Comment 1 Peter Hutterer 2012-10-30 05:04:39 UTC

Cause of the issue is that on the root window, the client selecting for events is not the window owner. This causes failed resource lookups in RetrieveTouchDeliveryData() and thus no event is ever sent.

Comment 2 Peter Hutterer 2012-11-02 04:31:56 UTC

FWIW, test cases:
TouchTestXI2Version.EmulatedButtonMaskOnTouchBeginEndCore
TouchTestXI2Version.EmulatedButtonMaskOnTouchBeginEndXI2

This is a mass change of bugs. Bugs assigned to me that haven't been updated in the last 3 years are closed as WONTFIX, because, well, let's at least be honest about it.

Please do not re-open unless you have a really good reason to do so (e.g. you're fixing it yourself). If it hasn't been fixed in the last 3 years, it probably won't be fixed anytime soon either. Sorry.
