Description Oskari Saarenmaa 2009-03-25 17:14:25 UTC 
Description of problem:
CONFIG_MOUSE_PS2_ELANTECH is required for EeePC 901 touchpad to be usable with the synaptics driver.

Version-Release number of selected component (if applicable):
kernel-PAE-2.6.29-0.258.rc8.git2.fc11.i686
Comment 1 Chuck Ebbert 2009-03-26 03:49:13 UTC 
I'm not sure the xorg driver in f11 can handle that:

config MOUSE_PS2_ELANTECH
        bool "Elantech PS/2 protocol extension"
        depends on MOUSE_PS2
        help
          Say Y here if you have an Elantech PS/2 touchpad connected
          to your system.

          Note that if you enable this driver you will need an updated
          X.org Synaptics driver that does not require ABS_PRESSURE
          reports from the touchpad (i.e. post 1.5.0 version). You can
          grab a patch for the driver here:

          http://userweb.kernel.org/~dtor/synaptics-no-abspressure.patch

          If unsure, say N.

          This driver exposes some configuration registers via sysfs
          entries. For further information,
          see <file:Documentation/input/elantech.txt>.

Comment 2 Peter Hutterer 2009-03-26 04:07:22 UTC 
It does, the documentation in the kernel is wrong. first released version with elantech support was 1.0.

    Add support for touchpads (such as Elantech) that do not report pressure

    Change the driver to react to BTN_TOUCH if device does not report
    ABS_PRESSURE since there are touchpads (such as Elantech) that do not
    support pressure reading but otherwise are perfectly useable in absolute
    mode.
Comment 3 Oskari Saarenmaa 2009-03-26 07:02:33 UTC 
Yeah, I can confirm that it works, I just built "kernel-PAE-2.6.29-2.os2.fc11.i686.rpm" with the option set and the driver works fine.
Comment 4 Dave Jones 2009-03-26 18:05:48 UTC 
enabled in cvs.
Comment 5 Casey Jones 2009-03-31 04:35:09 UTC 
I can also confirm this on my Eee PC 900.
If I use the kernel from the F11 Alpha, it works fine, but using the latest kernel breaks tap-to-click.  So I'm guessing somewhere down the line this option got disabled.  Is there an ETA on when this will hit Rawhide?
Comment 6 Oskari Saarenmaa 2009-03-31 07:30:00 UTC 
It's already in rawhide (kernel-2.6.29-16.fc11).
Also disabling tap to click is part of the "SynapticsUpdate" feature in Fedora 11, see http://fedoraproject.org/wiki/Features/SynapticsUpdate
