Yes, I've reverted to that for the moment. And I've reverted to 32 bit
rather than 64 bit Ubuntu. Still no joy. There is however still a
problem with compiling the Matrox drivers; although the 'mtx' driver is
loaded, available to X11 and works, several additional kernel modules
still don't compile. It is possible that the function we need is
provided by one of them. (I'm fixing errors, but it's a moving target
so far - maybe the current one is the last one?) There are also several
versions of the Linux drivers out there, I shall be checking for
differences.
