Douglas, can you please make a recording of your touchpad/trackstick
with ps2emu-record?
Download it from https://github.com/Lyude/ps2emu , compile it and run
it as root:
- once the touchpad gets re-initialized:
- click once, wait a few seconds
- click twice, wait a few seconds
- click three times, wait few seconds
- use the touchpad a bit, wait a few secs
- use the trackstick (and its buttons) a bit
- Ctrl-C
And send us the resulting file ps2emu_record.txt that will be created
in the current directory.
Can you also confirm that your laptop has a trackstick as seen on
http://www.newegg.com/Product/Product.aspx?Item=N82E16834114551 ?
Cheers,
Benjamin
PS: I am not sure we tested ps2emu-record on an Alps touchpad before,
apologies if there are some hiccups...
