A strange thing happened. I looked at dmesg when I booted back up, and here is what I got (while the touchpad was still working): # dmesg | grep mouse [ 1.771332] mousedev: PS/2 mouse device common for all mice [ 2.378989] psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x4d5f02) [ 2.392941] psmouse serio1: elantech: Synaptics capabilities query result 0x00, 0x15, 0x10. [ 2.407055] psmouse serio1: elantech: Elan sample query result 0c, 02, 75 [ 336.607211] psmouse serio1: Touchpad at isa0060/serio1/input0 lost sync at byte 6 Then I moved the cursor with the touchpad again until it stopped moving, as before. After that, I ran the command again: tribeDellbig:/home/george # dmesg | grep mouse tribeDellbig:/home/george # Nothing - doesn't read anything there now.
