Problem may have been fixed in new upgrades. Several packages have been upgraded by Ubuntu since reporting bug - a dpkg.log list is attached. Also removed xserver-xorg-video-intel as Ubuntu recommend not to use it for newer PCs. System has now been stable for a day, even with 2 USB mice. Re-installed xserver-xorg-video-intel and ran OK for a while, but then locked, so suspect this driver. Xorg.0.log now shows error loading driver (as cannot find it), but appears to run OK.
