Apologies, forgot to mention I'd checked IO. Well, when I say checked.
The disk light is not on before/during/after the mouse pause. Should I
use something like iostat? It's not installed & I haven't tried it.
Have also checked dmesg, nothing unusual.
The mouse pause will happen immediately after a reboot, with no
foreground apps running. So It's unlikely to something I'm using. It
must be a background process or hardware issue.
Wonder if it happens before I log in...
Nope, doesn't happen when I'm not logged in.
Before login, head 3 (on a second video card) is disabled. Sadly it
doesn't happen after login if head 3 is disabled. :(
Disabling one of the heads on the first video card has no effect. So it
may well be something to do with the second card.
What to I try next???
