I have an interesting situation with the mouse on the little woman's box. I recently swapped her old two-button for a three-button Logitech mouse. The new mouse doesn't work on her box, but it does on mine. The relevant sections of the /etc/X11/XF86Config-4 file are identical. Early on, I did notice that her keyboard was wrongly identified as pc105 (instead of pc101), so I corrected that, restarted the X server and it worked until the next time she booted.
So, for now, she's back to the two button mouse. This is on the most current woody, with KDE. Any help would be appreciated. from XF86Config-4 Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device" "/dev/psaux" Option "Protocol" "PS/2" Option "Emulate3Buttons" "true" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" Identifier "Generic Mouse" Driver "mouse" Option "SendCoreEvents" "true" Option "Device" "/dev/input/mice" Option "Protocol" "ImPS/2" Option "Emulate3Buttons" "true" Option "ZAxisMapping" "4 5" tia bob
