Description Crashbit 2012-04-27 23:13:05 UTC
Created attachment 73116 [details] devices.txt My Dell XPS 13 Ultrabook can't detect Cypress Trackpad correctly. It detected as 'ImPS/2 Generic Wheel Mouse'. 'Cypress Trackpad' works just basic function not fully. The trackpad(touchpad)'s L-button and R-button works and scrolling and dragging work not perfectly. Tapping work not perfectly, either. For tapping, I should tap and hold the tapping for about 1sec. and then, it recognize tapping. In launchpad exists a bug with this problem: - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/978807

We do not have dedicated Cypress touchpad support in kernel at this time...

Cypress touchpad has been added to Lenovo laptops now, I have an ideapad U400 and I have the same problem.

Is Cypress touchpad support in the kernel yet?

(In reply to comment #5) > Is Cypress touchpad support in the kernel yet? It is now in the upcoming 3.9.x.
Comment 7 emailgrant 2013-04-19 23:27:52 UTC
And it works great! :)

(In reply to comment #7) > And it works great! :) It really does for you? Using no specific config here and it "feels" slow and it doesn't react on taps, only the click-area can be used. Care to share your config (if you have specific one)?
Comment 9 emailgrant 2013-04-20 00:39:15 UTC
I actually have no config at all. It just feels better to me. I hate taps. :)

The new versions of kernel solve this problem!
