I also had these problem.APP1,APP2,APP3...use surface->lock to share the
screen which are running well togather without keyboard input just using
/dev/mice directly.If I use DFB input event buffer on APP1(first run),only
APP1 can show,other apps can run but like wait at surface->lock and without
display.:confused:
this is APP1 running like a server:
(*) DirectFB/Input: IMPS/2 Mouse 1.0 (directfb.org)
(*) Direct/Thread: Running 'Keyboard Input' (INPUT, 13097)...
(*) DirectFB/Input: Keyboard 0.9 (directfb.org)
