Hello Kamal Unfortunately, We're not able to upstream the driver as it would be denied because it changes the Linux mouse structure framework.

In fact, Canonical is working on preparing the Cypress PS/2 trackpad driver for submitting upstream. > Is it too hard? I don't think so as the patches are quite non-invasive > and small. Your estimate of the work/risk involved not withstanding, I chose to deploy this experimental driver in stages -- first in the oem-specific "Sputnik project" kernel, then (recently) in the main Ubuntu kernel, then finally (soon) upstream -- so as to minimize regressions while shaking out the bugs. For example, the version to which you linked does include a regression (breaks some ALPS touchpads) which we discovered only after deploying in Ubuntu. I expect to submit the Cypress driver upstream within two weeks. Of course, my work on the driver is (and has been) publicly available[1]. -Kamal Mostafa <kamal@xxxxxxxxxxxxx> [1] The latest version of this driver is represented by the patch set: http://kernel.ubuntu.com/git?p=ubuntu%2Fubuntu-quantal.git&a=search&h=HEAD&st=commit&s=Cypress+PS%2F2 > > Is the only distribution around is Ubuntu? > Is the only laptop sold in the world is Dell XPS13 with an Ubuntu? > > I'm not trying to be impolite but it hurts me to see that a vendor > produces an open-source driver for its device but makes use of it only > through a specific distribution. > > If Cypress is just beginning developing open-source drivers for their > devices, I hope that after this mail they will be much sensitive about > the issue and push their drivers even before the release of their > devices to make user experience flawless. > > (I googled and searched the archives of LKML and linux-input but > couldn't find a discussion or patch series about the driver.
