[Bug 550625] Re: Alps touchpad is recognized but synaptics clients and scrolling do not work

 

Version 0.10 of the psmouse-alps-dkms package is available at

  http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.10
/psmouse-alps-dkms_0.10_all.deb

Changes since version 0.9 include:

 * Changing the way the trackstick buttons are quirked on v3 models to
fix a false positive on the Dell Latitude E6320. If your model has a
trackstick, please verify that the trackstick buttons continue to work.

 * Stricter criteria for identifying touchpad position packets on v3
hardware.

Please test and let me know if you encounter any problems.

If you are one of the few seeing occasional erratic behavior from the
touchpad, I *really* need to get some packet dumps in order to see
what's going on. I've been trying to reproduce this behavior without any
success. When you see this behavior, please do the following steps:

 1. Switch to a virtual terminal by pressing Ctrl-Alt-F1

 2. Log in, then run  'echo 1 | sudo tee
/sys/module/psmouse/parameters/alps_dump_packets'

 3. Identify the touchpad device in the output of the lsinput command,
then run 'input-events device_number > input-events.txt', replacing
device_number with the number of the touchpad event device in the
lsinput output.

 4. Do whatever causes the erratic behavior. It won't show up on the
screen when in a virtual terminal, but the data will still be collected.

 5. Press Ctrl-C to quit input-events

 6. Run 'dmesg > dmesg.txt'

 7. You might try running 'sudo modprobe -r psmouse; sudo modprobe
psmouse' here, as this might get your touchpad functioning normally
again.

 8. Type 'exit' to log out, then press Ctrl-Alt-F7 to return to your
desktop. Give me the input-event.txt and dmesg.txt files.

Thanks!
