Bug#653156: xserver-xorg-input-synaptics: description in man-page brakes functionality of the driver
Package: xserver-xorg-input-synaptics
Version: 1.5.0-2
Severity: important
Dear Maintainer,
the ETPS/2 Elantech Touchpad of my MSI laptop stopped working after upgrading to
version 1.5.0 of the synaptics driver. In the log file /var/log/Xorg.0.log the
following error messages appeared:

The file /etc/X11/xorg.conf contained the line
Option "Protocol" "auto-dev"
After removing this line the synaptics driver worked again.
My point is that in the man-page of synaptics the following text appears:
Option "Protocol" "string"
Specifies which kernel driver will be used by this driver. This
is the list of supported drivers and their default use scenar-
ios.
auto-dev automatic, default (recommend)
event Linux 2.6 kernel events
psaux raw device access (Linux 2.4)
psm FreeBSD psm driver
Shouldn't this text be revised? And may be a warning about this behavior be
added to the file changelog.Debian.gz?
Please fell free to contact me, if further information is needed.
Best regards,
Jörg-Volker.
