The pointer issue occurs if am using a mouse or just the touchpad.

Hardware it certainly could be-  so central could it be mother board?

I will check syslog next time.  Fan is not running much.  I'll install temp
sensor and check again.

I forgot one other issue.  Last few times at boot, the system has lagged
badly after the login screen.  Even clicking on one file and then another
shows excessive lag time.  I've seen an image of the desktop in the lower
right hand corner of the screen.  That disappears and the lagging remains
for a few minutes.  Programs are very very slow to load.   Shall I post the
bootlog?  I do not see any error messages in it.  I installed a cloud
program shortly before this started happening.  i deinstalled it but that
made no difference.

thanks for the replies!
