So things are fine as long as I stay with BSD Unix and years-proven Xlib. Things become different as soon as I port the program on a PC running openSUSE 11. I receive mysterious warnings from 'libxcb', seemingly harmless; but occasionally the program gets aborted because of a failed assertion in xcb_lock.c: 77: _XGetXCBBuffer blablabla... What can I do? I don't intend to twiddle with the system internals, and not to study recent developments, either.  While I am generally sympathetic to efforts such as XCB, to make things lighter, more transparent, and (hopefully) correct --- I'd prefer to see my program running on the Linux machine, just for demonstration and teaching purpose. (Fortunately, the target machine for the program's use in the lab is the old Mac :-) Can anyone help?  How can I shield myself from the wave of modernity and keep my old-fashioned Xlib-based programs running?
