You may want to try ccmake instead of cmake -i, the interface is much nicer.

This may be fixed in 4.2.3, but I will check.

This is not a vtk issue.   This is an X11 issue.  Can you run
other opengl based applications and have them work?

Some of the tcl examples require hybrid or parallel, so if you don't build them, they
will not run.
