Each bit is triggered by GPIO interrupt. When in console mode, GPM works fine, and I can see the mouse cursor moves correctly. But When entering GUI, say QT or microwindows, the following messages occurred: Mouse at xxxxx/serio0/input0 lost synchronization, throwing 1 bytes away. .. Mouse at xxxxx/serio0/input0 lost synchronization, throwing 1 bytes away. Mouse at xxxxx/serio0/input0 lost synchronization, throwing 2 bytes away. And the mouse cursor is floating and moves incorrectly. What is the criteria that kernel think the mouse packet is lost of sync.?
