Comment 78 for bug 550625

Today I updated to linux-image-2.6.32-22-generic (version 2.6.32-22.33) from the official lucid repositories, but edge scrolling doesn't work when I remove the below workaround.
I'm using Sony VAIO EB1E1E (see https://bugs.launchpad.net/bugs/554050) and maybe my touchpad has different device id.
Please let me know how to check the device id.
I tried with dmesg, but I couldn't find anything that looks like the removed line from the patch attached to this bug.

It's good we have this permanent workaround in the mean time;
Add the following to /etc/modprobe.d/psmouse.conf:
options psmouse proto=imps

The psmouse.conf file doesn't exist by default, just create a text file with that name in /etc/modprobe.d/

Regards,
Rocky
