Hello fellows,
if anyone has had such problems with the mouse-device like freezing and suddenly holding the pointer into one static position on the screen - > here is the solution. When such occasion happens all you have to do is just to press RIGHT ALT+CTRL+BACKSPACE to restart the mouse device without restarting the whole X-server. JUST REMEMBER to press "RIGHT" and not "LEFT" keys. In case of pressing LEFT ALT+CTRL+BACKSPACE X11 server will get restarted and you have to login again.
That's for now.
