I'm running antiX-M8.5, upgraded via smxi to the sid repos and kde4.5. The mouse cursor disappears from the screen if the mouse is left stationary for a short period of time. I understand that this is likely preferred behavior for many folks, but for me it's not. I've fished around in kde's systemsettings and found nothing related to this. Another of my systems which is Mepis/sid/kde4.5 does not do this, so I'm suspecting it's something in antiX. Anybody know how to turn it off?

Either remove unclutter (apt-get purge unclutter) or disable it from starting automatically (I don't remember exactly but I think the settings are in /etc/X11/Xsession.d/unclutter; there's a post about this in the forum).

Perfect. Thanks!
