I'm not sure what you are trying to do so I do not know why you would want to write a driver. In any case, your X server has to support the XTest extension. (Most do.) You can use xdpyinfo to determine this. You'll get something like: </tt> <blockquote><tt>number of extensions: 16</tt> <tt> BIG-REQUESTS</tt> <tt> ...</tt> <tt> XTEST</tt> <tt> XTestExtension1</tt> <tt> ...</tt> </blockquote> <tt>Programmatically, use XTestQueryExtension. Next you need to determine if the server is going to allow you to grab control. Use XTestGrabControl for this. After that, depending on what you want to so, use: XTestFakeMotionEvent (pointer motion) XTestFakeButtonEvent (mouse button press/release) XTestFakeKeyEvent (keyboard key press/release) </tt> <tt>I didn't find any man pages on XTest but am sure there are some floating around somewhere. In any case, the code is pretty straightforward: xc/lib/Xtst/XTest.c.

This is mainly for testing. Eventually I intend to either write a proper kernel level driver of an X input diver. Any advice or pointers? Thanks, Erik </pre> </blockquote> </body> </html>
