I'm not sure this is the proper list, but perhaps someone can offer assistance. I'm writing a program that I want to be able to move the mouse pointer on screen (preferably independent of window manager). I couldn't find a way to do this from within X, so I created a named pipe and set X to read from it as a second mouse with the same protocol as my physical mouse (IMPS/2). I cat'd /dev/input/mouse0 to a file while performing some simple mouse actions (cliking the buttons then moving in a square) and wrote a program to write that 3 bytes at a time to /dev/input/mouse0 to see if it would reproduce the movements, instead the pointer flailed about wildly and went semi-unresponsive (the pointer would still move, but mouse and keyboard input would only go to the window with focus, which couldn't be changed--it's as if the mouse input was still waiting for a missing byte or something). Probably writing the bytes so quickly caused acceleration in the mouse driver to kick in, which would explain the jumpy movements, but it doesn't explain the semi-unresponsiveness. I've also tried doing things like echo -e '\000\020\000' > /dev/input/mypipe which succeeds in moving the pointer either up or to the left, but I can't do mouse clicks or move down or to the right, even if I echo, say, the 3 bytes that were produced in /dev/input/mouse0 when I right clicked. Does anyone have a suggestion as to a better way to proceed? Are there functions either in X or gnome/kde that would be better suited to this?
