           Summary: (evdev) assuption about Synaptics coordinates limits
                    wrong.
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.26.3
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: low
          Priority: P1
         Component: Input Devices
        AssignedTo: drivers_input-devices at kernel-bugs.osdl.org
        ReportedBy: batchman at free.fr


Distribution: Debian unstable
Hardware Environment: Dell inspiron 1520 laptop.
Synaptics touchpad detected as :

[   11.415975] Synaptics Touchpad, model: 1, fw: 6.3, id: 0x1a0b1, caps:
0xa04793/0x300000
[   11.415975] serio: Synaptics pass-through port at isa0060/serio1/input0
[   11.454365] input: SynPS/2 Synaptics TouchPad as /class/input/input5

Problem Description:

the current evdev synaptics driver reports limits dictated by the Synaptics
Interfacing Guide (1472-5472,1408-4448), but on this hardware, limits are more
like (1220-5900,900-5000).

This confuses the synaptics xorg driver and makes it consider larger scrolling
area and less motion area.

Steps to reproduce: get a laptop like this, and use the touchpad and/or have a
look at synclient -m 10

Workaround : use your touchpad differently or configure the driver to use
different limits.
