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 <[email protected]> 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. Signed-off-by: Kevin Cernekee <[email protected]> Tested-by: Dave Turvene <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]> 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.
