I can use this machine only on Sunday mornings.
I will do these tests on next Sunday.
But using this message, do you suggest any Linux distribution, based on
Debian, which would be a good alternative to install on this machine?
Nothing I wrote was meant to imply Jessie was an inappropriate distro
choice.
Rather, Gnome3 is more demanding than your hardware was designed to
support.
So, (optionally) removing gnome-desktop, and installing any other
desktop is
what I would try first. Several less demanding options are available. My
preference is overwhelmingly TDE, regardless of hardware capability.
https://wiki.trinitydesktop.org/DebianInstall#For_Jessie_.28Debian_8.x.29
has
TDE installation instructions. The home page link there will provide
better
description than I can offer.
This desktop will beused in educational environment.
Any suggestion?
Unless your 160GB disk installation unusually constrained your /
partition
size, you can install multiple desktop environments, try each, then
simply
continue using whichever turns out to be your favorite, optionally
removing
the others.
https://wiki.debian.org/DesktopEnvironment lists Debian's primary desktop
options. If you've been a Gnome user in the past, Mate may turn out to be
your preference.
Alternatively, if switching to another distro is your wish, Edubuntu
might
turn out to be an ideal choice.
