Description Stuart Shelton 2005-03-18 07:39:10 UTC
On laptops with Alps touchpads, tapping is disabled in Linux 2.6.11 (and gentoo-dev-sources-2.6.11-r4).

There is a patch which apparently addresses this (aimed at Mandrake's kernels) available from http://sauvy.ined.fr/~brouard/sony/patches/2.6.11.3-nbmdk/

Could someone who understands how this works take a look at this patch, and if it's sensible add it to Gentoo's custom patches?

Cheers,

    Stuart

Actually, hardware tapping is enabled in gentoo-dev-sources-2.6.11-r4
Does it not work for you?

We include this patch:

Sorry, but I'm going to reopen this bug: Bug 84657 says that this problem was fixed in gentoo-dev-sources-2.6.11-r4, yet it was this kernel for which I reported the problem!

As far as I can tell, on my Sony Z1 laptop with Alps touchpad, this issue is still causing problems even in 2.6.11-r4.

The symptoms are:
* Tapping and Double-tapping not working at all (have to use buttons)
* Even when using buttons, selecting text is broken on console

To elaborate this 2nd point:

Even holding down the hardware left-button, moving the cursor too fast whilst selecting text or pausing for too long causes the driver to think that I've released and re-pressed the button, restarting the selection from the current location.  This is not a hardware thing, since all previous kernels work fine.  This only applies to (fb) consoles, rather than anything on X.

Lets keep it on the same bug
