Hi Robert,
Thank you very much for your help.
I finally find out that nvidia driver installed from elrepo.org was
responsible for my keyboard/touchpad issue.
I removed if, and uninstalled Mate + X Windows ; then reinstalled X
Windows and Mate.
First with "nouveau" drivers, keyboard and touchpad were back working.
Then I installed Nvidia drivers from nvidia drivers site (instead of
elrepo.org) ; keyboard and mouse still works now.
I think something breaks the keyboard / touchpad configuration with
elrepo.org... for this dell laptop E6420.
Best Regards
Edouard
