It turned out my report of success was wrong. However I think I cornered the
problem. The following lines are two snippets of xev output:
KeymapNotify event, serial 28, synthetic NO, window 0x0,
keys: 69 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
ButtonPress event, serial 28, synthetic NO, window 0xe00001,
root 0x145, subw 0x0, time 2952962341, (21,177), root:(1649,206),
state 0x0, button 1, same_screen YES
Both events are the result of pressing the left mouse button. Sometimes the
first, sometimes the second message appears. So it seems that Xorg has trouble
with /dev/sysmouse. If I omit moused and configure X to take the mouse from
/dev/ums0, everything seems to be fine. The same, if I opperate without a mouse.
