Hallo Steve, thanks for your reply! As I am not yet even near 60 years old, I don't get the reference. But I am old enough to sense, that I probably won't get much deeper into C programming anymore, than wrapping shell commands into the 'system()' function to make them setuid'able. Thus, I will leave the 'xinput' sources where they are and rather use some spare time to see if I can can get any useful information out of 'gdb'. If I succeed, I promise to report to the list - although I don't own a device with touchpad (which most likely would be the second thing to permanently disable immediately - right after the system sounds, if my OS had those preconfigured). Libre Grüße and best regards, Florian -- Together we stand - united we fall. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
