Hi all! An "apt-get upgrade" last night broke my mousewheel. Furthermore the mouse speed has decreased. (several (all?) XFree86 packages were updated) The problem is that "apt-get" seems to overwrite/change the X-config file: /etc/X11/XF86Config-4 So if you "apt-get upgrade" now, make sure you have a backup of that config file. Best regards, Hannes.
