Because of poorly functioning touchpad I wanted to provide more detailed configuration for it using xorg.conf.
So I create a new xorg configuration file by copying default configuration file using cp /usr/share/X11/xorg.conf.d/50-synaptics.conf /etc/X11/xorg.conf.d/50-synaptics-mod.conf
.
I reboot and check current values for two parameters (nothing should have changed now).
pca:~$ synclient -l | grep 'VertScrollDelta\|EmulateTwoFingerMinZ'
EmulateTwoFingerMinZ = 282
VertScrollDelta = 24
So far everything seems OK, there are just some default values in there.
Now I would like to change these two parameters.
So i open created file /etc/X11/xorg.conf.d/50-synaptics-mod.conf
and modify this section
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
#Option "EmulateTwoFingerMinZ" "13"
#Option "VertScrollDelta" "17"
EndSection
by adding two options that are commented out in the snippet.
I reboot and get values
pca:~$ synclient -l | grep 'VertScrollDelta\|EmulateTwoFingerMinZ'
EmulateTwoFingerMinZ = 13
VertScrollDelta = 24
So EmulateTwoFingerMinZ
was modified as expected. But for whatever reason VertScrollDelta
remains the same.
What could be behind this madness?
I am using standard ubuntu
, gnome
and synclient VertScrollDelta=17
works fine.
