Subject: Possible regression 3.8.7 -> 3.9 with Dell touchpad
Date: Thu, 09 May 2013 22:59:58 +0200 [thread overview]
Message-ID: <20130509205958.89890@gmx.com> (raw)
Hi,
I found that after upgrading my kernel from 3.8.7 to 3.9 my touchpad only
works partly. By that I mean I can use the touchpad to move the cursor
around, but I cannot click with it by tapping. My machine is a Dell
Latitude E5530. Since it is 100% reproducible on my machine, I bisected it,
and found this commit:
commit 1302bac33d9e88cd43e482191a806998f3ed43cc
Author: Kevin Cernekee <cernekee@gmail.com>
Date: Wed Feb 13 22:27:08 2013 -0800
Input: ALPS - add support for "Rushmore" touchpads
Rushmore touchpads are found on Dell E6230/E6430/E6530. They use the V3
protocol with slightly tweaked init sequences and report formats.
The E7 report is 73 03 0a, and the EC report is 88 08 1d
Credits: Emmanuel Thome reported the MT bitmap changes.

I did the bisection between 3.8.7 and 3.9, but also tried 3.9.1, it is bad
too. I also tried reverting that commit to make sure that it really is
what made my touchpad not working. The revert did fix my problem.
That's all I gathered so far, but I'd be happy to help further in any way
I can, just let me know.
Thanks,
Tibor
