I will admit that part of why I hadn't previously reported it (in addition to
thinking that my prior hardware had something to do with it) was that I would
have expected seeing people screaming about this if it really was a problem
in X itself (or at least running on FBSD(-CURRENT). Weighing against that,
however, is the fact that I do not see this at home running the same
software, the same configuration (I configure KDE the same way, etc) and
basically the same apps. However, I will see if I can start with disabling
kscreensaver entirely (that may or may not work for me, since I think the
screensaver has to be active to lock the display) and see if that helps over
the long weekend.
