Touchpad on hp 255 G1 laptop no longer works after updating to ubuntu 14.04.

https://bugs.launchpad.net/ubuntu/+bug/1326822

Try loading the psmouse module with various options like:

proto=imps
Or
proto=bare

Also try the boot option:

i8024.reset
Or
i8024.nomux=1

May help

Hi actionparsnip,
Thanks for sending me these suggestions, I couldn't get any joy out of them though.

When I tried proto=imps this is what came back:

i8024.reset:

I don't know if that will help you diagnose whats the matter with it... I'm a noob with no idea what any of it means really, so would really welcome any suggestions!

Thanks again for helping me

Its nothing to do with apt.

I have just had the same problem and I sm fairly sure it is because when I upgraded to 14.04 I inadvery discarded the specific driver needed for the HP 255 G1 keyboard and touchpad. One reason for thnking that is that a few of thr keys miss map: @ displays as " and vice-versa. I have not fixed the problem yet. Have you?
