Even without looking at your graphics card, I've gotta say, you shouldn't be running Cinnamon on a computer with those specs.
Cinnamon is graphics-intensive, and failing a good graphics card, can be resource-heavy. It really isn't meant for older computers.
I advise that you either download a different version of Mint (MATE, since the familiar layout will make it easy) or install another desktop environment.
To install another desktop environment:
-Open a terminal
- Code: Select all
sudo apt-get install mate-desktop-environment
and enter your password when prompted (nothing will come up while you're typing; this is normal)
-After the installation finishes, log out
-At the login screen, click on the sessions button and choose MATE
