I have now tried commenting out the "xf86XInputSetScreen" call which I found on line 259.
I tried it with the unadulterated Debian source which caused X to hang: I could only restart the machine by holding down the power button. I then tried it both with the "is_core_pointer=0" and with "is_core_pointer=1". They both produced the same result which is the last result I described: no pointer movement but output appearing from "cat /dev/ttyS1". I'm afraid that I do not understand what "try those two" mean. I presume that the second item is related to freedesktop bug 10324, but I could not identify the test. Many thanks for all your help. (Sorry about the delay in responding, I have been forced to live outside of my home for the last two weeks due to leaking from an upstairs neighbour. This shall mean that I shall also be away from my home between 2nd Feb and 23 Feb while the serious work is done on repairs.)
