I'll summa= rize the situation on my E220S here, which I believe to be more or less the sa= me as the situation on the X220: - Main device is a Synaptics touchpad/ - Trackpoint exists as a passthrough device/ - Trackpoint not detected until first resynchronization happens. - Loss of sync can be triggered by moving the (undetected) trackpoint/ There seems to be a slight difference here though, in that I can't disabl= e the trackpoint or touchpad in my BIOS. I noticed that you requested for the full i8042.debug output, so I looked= into doing just that, using the following steps: 1. rmmod psmouse 2. echo 1 > /sys/module/i8042/parameters/debug 3. modprobe psmouse 4. wait for i8042 to settle and stop spewing messages 5. move the trackpoint a bit. 6. wait for i8042 to settle and stop spewing messages again. I have attached two snippets of /var/log/kern.log files to this email: - modprobe-psmouse-until-settle.log: The log output between steps #3 and= #4. - touch-trackpoint-until-settle2.log: The log output between steps #5 an= d #6. There are no messages output in between the two log files. I have just sp= lit them for easier consumption (especially considering that the second log f= ile is 4210 lines long). Please let me know if you need more information. Also, please CC me for replies, as I am not subscribed to this list. --=20 Kind regards, Loong Jin --------------enigA8165FB0829D38CFB99CA4BF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJOit2YAAoJEPvVIltYh1KhAAoP/R3xP1wdBpeAU0P9m1mu1Ldp Tmd30AayL2F74vWYE1dGkrOSzw9PU8cMwfm/JmnzbotjtNNOFAnqIB1pUKbeo1D0 F3uzBqUxPTUyTAYyYeiBsIh+OBkPpckDf2LOlM5FWO6BCdUKjBs5FyFZTbsDT7Gk wh1LgZdAY85WBH2YW1y1x95c1CqSOEpCJ/vwS3wR1j49ymFW2a6/OxhqkbwCNsrs xQwqFI02aPhs1Y9fUs/3CzRleWt8w8495RFTNCgjhO2jk7RvbvX4j1SaiCQQ38HD Dr77LIXMoCIAJxfuSZxBxxx84rD5oJ0UEThARfDWJVaFAtrr4P8yXMJ+Xx0ckydF HoToxDm4Kb8ysHo0Gqdnwyju++p6e+Ktdc8qj7S2Qgl5oMP0PkOvCYHgNuq5h42T NjpnMvLkQwm3d58SlMlHBTTgrDERbuI5Cx7Yr9NxL2Ad9TW9dW6syNfpBQEgw6kB DceNdYLtLRq24HqY/+/PpxUjOhZ9T4sGz73sn4mKCESIBTv8zcHm8/B5CgbsL6XJ u5GVfaS5Hhe5GUYcNbSkudmYN8cDqjmnyBCLYN0Y+srC/kQctntthSXGy6udxPfd RaydYF612REKFhjO/Sk/SAzbD79Dm0WMvrpbMfOrZnyWh24GQS/acxQnbw87Hxhw Fg5yNvQyDxhQKRji9bIS =jYZ3 -----END PGP SIGNATURE----- --------------enigA8165FB0829D38CFB99CA4BF--
