Here, I cannot see dojo with one my laptops, but I can see it with the other.
Cannot see: Thinkpad X60 with Intel 845 graphics.
Can see: Thinkpad T42p with ATI FireGL T2 Mobility (or something close to that) using the proprietary fglrx driver.
On both laptops, running Toribash 2.73 on Ubuntu 7.04.
Maybe relevant: on the X60, I do not have anti-aliasing and the following warning when starting Toribash.
Unable to create OpenGL FSAA screen: Couldn't find matching GLX visual
Trying without FSAA instead
On the T42p, this warning is not displayed and antialiasing works.
I am wondering whether maybe, the dojo line is less than a pixel thick and is aliased away on the X60.
