Red Hat Bugzilla – Bug 212753
Synaptics touchpad parameters should be set sanely and changable on the fly
Last modified: 2018-04-11 11:08:13 EDT
Description of problem:
The Synaptics driver supports runtime configuration changes if the parameter
Option "SHMConfig" "yes"
is set in the InputDevice section of xorg.conf for that driver; there was no
such setting in my xorg.conf after running system-config-display --reconfig.
After setting that parameter, users can use e.g. gsynaptics to configure their
touchpads to their liking. Unfortunately this is not done by
system-config-display, so the per-user configuration utilities are completely
useless by default. (The manpage for synaptics does warn that turning this on
lets any local user change touchpad parameters, is this the reason why the
feature is not turned on?)
The defaults might need some work too. Perhaps e.g. the side scrolling should
also be turned off by default:
Option "HorizScrollDelta" "0"
since that seems to be the most potentially confusing behavior, and it interacts
pretty badly with firefox - it's really easy to skip back and forth by mistake
(cf. e.g. bug #187412).
Version-Release number of selected component (if applicable):
Created attachment 139679 [details]
Add the "SHMConfig" option to the defaults for Synaptics touchpads
Patch to default-enable configuration of Synaptics touchpads using e.g.
Changing component to rhpxl, since that's where the actual settings for the
touchpad are handled.
