Incompatibility with Unity

It has been reported than Xcas does not work correctly (crash, keystrokes not recognized...) under some versions of Unity (default window manager in recent Ubuntus). If you experience these problems, it is recommended to switch to an alternate window manager like Gnome, Xfce, Icewm, ...

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.

Khicas: Giac for the TI Nspire

An experimental version of χcas for the TI Nspire (CAS, non-CAS, CX or older model) is available. Requires Ndless (OS 3.6,OS 3.1), your Nspire OS must be version 3.6 or earlier, do not upgrade to version 3.9 or later. If you have OS 3.9 installed on a nspire CX, you can downgrade to OS 3.6, see this howto.
Warning: do not use khicas in exams where CAS calculators are banned.
For interested developers, install the Ndless SDK, then additional libs/headers (modified versions of nspire-io, USTL, tommath) and the giac source code.
Thanks to Xavier Andréani and Adrien Bertrand for the LUA interface.
