I am on windows and never had a Linux, but I will try my best
to share my experience.

I think that "menu checkbox" means the item on the top left
of the B3DSceneExplorerMorph. That checkbox is labelled
"Enable hardware acceleration". Right?
On Squeak for Windows, we have a menu item (in the window menu)
"VM preferences" and a submenu "Display and Sound" with three
items. It is important to check "Use OpenGL (instead of D3D)"
Hardware acceleration needs OpenGL; it will not work when you
use D3D.
When you try Hardware acceleration with the rotating cube,
the effect is not very impressive (IMHO). For more
complicated scenes, I found hardware acceleration more
impressive. When you use hardware acceleration on a
Windows PC, the colors of the scene change, this is a
well-known bug, but also an indication that hw acceleration
works.

You need an OpenGL driver. Most modern operating systems
have one, but if you need one, you will find it on
http://www.opengl.org/
