Yes - the firmware is very good at fixing the drift so it isn't 
noticeable to the user. One pixel per 3 minutes is only noticeable if 
you set out to measure it!  But it does stop kde's screensaver from 
activating.

However, xscreensaver doesn't have this problem: it treats tiny mouse 
movements (< 10px in a certain time) as negligible.

One supplementary bug. xscreensaver now fails to put the display into 
power-off mode. This is definitely a bug. Oddly:

1) xscreensaver's power management DPMS settings do take effect, and are 
shown by xset -q

2) Manually setting DPMS timeouts (xset dpms xxx yyy zzz) does work. But 
if I let xscreensaver set the same values, it doesn't.

3)xset dpms force off    does what I want.

Any ideas?

Thanks for your help,

Richard
