Description Markus Wernig 2012-05-28 11:17:22 UTC
I have the following Synaptics touchpad in my HP Envy:

[    8.218270] psmouse serio1: synaptics: Touchpad model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04773/0xe40000/0x5a0400
[    8.308567] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input4

After the latest world emerge the synaptics touchpad (both xf86-input-synaptics-1.6.0 and 1.6.1) behaves in a strange way:

When using the hardware left click button, the left click event reaches the application. But when then trying to drag the mouse (as e.g. when selecting text or moving windows around the screen), the movement does not seem to be transmitted and the pointer does not move.
It does change cursor shape, though (eg. when clicking on the window title bar in KDE and trying to move the mouse for moving the window, the cursor changes shape to the "four pointed arrow", the desktop effect desaturates the window content as it would when moving, but the mouse does not move)

There is a description of the same bug some time ago in ubuntu:

This is exactly the same behaviour.
Up to the point that 
- double-tapping and then moving the mouse works
- the left click button kind of works when pressing down only the very utmost edge (eg. with the tip of the fingernail, using 1 mm of surface)

The problem occurs with xorg 1.11.4 and 1.12.1.

No problem that seems related is reported in Xorg.log

The problem does not occur with xf86-input-synaptics-1.5.2. 
After a downgrade to 1.5.2 the touchpad again works as expected.

Reproducible: Always

Steps to Reproduce:
1. Install >=x11-drivers/xf86-input-synaptics-1.6.0
2. Try to use the left click button of the synaptics touchpad to select text or move a window

Comment 3 Chí-Thanh Christopher Nguyễn gentoo-dev 2015-03-30 12:14:36 UTC
older xf86-input-synaptics versions will be removed due to bug 544094. If you are still seeing this problem, please work with upstream to get it resolved in newer versions.
