    Convert wl_input_device to wl_seat (and friends)
    
    wl_input_device has been both renamed and split.  wl_seat is now a
    virtual object representing a group of logically related input devices
    with related focus.
    
    It now only generates one event: to let clients know that it has new
    capabilities.  It takes requests which hand back objects for the
    wl_pointer, wl_keyboard and wl_touch interfaces it exposes which all
    provide the old input interface, just under different names.
    
    This commit tracks these changes in weston and the clients, as well as
    similar renames (e.g. weston_input_device -> weston_seat).  Some other
    changes were necessary, e.g. renaming the name for the visible mouse
    sprite from 'pointer' to 'cursor' so as to not conflict.
    
    For simplicity, every seat is always exposed with all three interfaces,
    although this will change as time goes on.

I don't recognize the xkbcommon version here.  There have been protocol changes recently that could break things like this, but usually we coordinate breaks like that so that master of all repos always work.  I can't reproduce this problem, can you try again with master of at least wayland, weston and libxkbcommon?

> Xkbcommon: (master)8ca8f05aab86423c2495cd917489becfecca4632

That is the last commit in libxkbcommon master:  http://cgit.freedesktop.org/xorg/lib/libxkbcommon/log/

That's in weston, and is 51 commits old.

The issue can be reproduced at the lastest version:

I'm not seeing this problem.  I'm running weston-terminal from the icon on the launcher.  I have weston set suid root.

The weston commit I used is newer than the one you used.

Yes, I've seen it myself a few times now.  It's a stuck modifier problem and I think we should be able to fix it today.
