Note for 3-d on Linux

Xcas is using OpenGL capabilities for 3-d graphs and 3-d geometry, therefore you must check that your Xserver is correctly configured. If acceleration is supported for your videocard, check that the dri module is loaded in /etc/X11/xorg.conf or /etc/X11/XF86Config-4. If Xcas freezes on a command like plan(z=0), remove dri loading or install the correct drivers for your video card.
