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. https://www.edubuntu.org/ -- "The wise are known for their understanding, and pleasant words are persuasive."
