I now remember that everytime this problem occurred, a USB mouse was disconnected. So, this may be related. Note: the machine is a laptop. * After disconnecting the USB mouse, the buttons of the touchpad have no effect over the root window. * After disconnecting the USB mouse and reconnecting it[*], the buttons of this USB mouse have no effect over the root window. In both cases, the problem disappeared just after quitting VLC. [*] This actually occurred due to a problem with a USB cable. I had already mentioned the issue related to VLC here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=805168#27 -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
