14.04mousetouchpad
I'm trying to figure out how to enable mouse acceleration in Ubuntu 14.04.
I have an XPS 15 9530, which has a built-in touch-pad (which appears to be recognised, as seen in the screenshot below), but I also have a Microsoft Touch Arc mouse, which works, but doesn't have any acceleration, meaning it's very slow to use.
Is there some way I can enable acceleration?
Definitely not the only way, but one way to do it would be to install gpointing-device-settings and check the "Disable while any other devices are connected" checkbox in the "General" tab for your touchpad.
Install the package gpointing-device-settings
Description-en: configuration tool for pointing devices
GUI tool for setting pointing devices. Currently it can configure mouse type
device (mouse, trackpoint etc.) and touchpads.
.
For mouse you can configure middle button emulation, wheel emulation and
scrolling.
.
It can enable and disable touchpad, or scrolling on it as well as additional
parameters like palm detection, locked drags, tapping and scrolling.
.
It is a successor of GSynaptics.
Alternatively, try this:
gsettings set org.gnome.settings-daemon.peripherals.mouse middle-button-enabled true
The alternative solution might require the installation of gnome-settings-daemon package.
Using synclient command you can view your synaptics touchpad options.
Run synclient and see what variables you have available.
You can set/change the synclient options using this command: syclient var=1 (where var is the variable you wish to change and 1 the value)
Read the manual page about each variable: http://manpages.ubuntu.com/synaptics
Instead of figuring out how to press both buttons of the touchpad, keep/press two fingers on the touchpad and click on the left click button of the touchpad with a third finger. This emulates a middle button by default.
a) Setting the TapButton variable works for the two fingered tap
b) If you still want to click both buttons and produce a middle button emulation, execute:
synclient EmulateMidButtonTime=100
EmulateMidButtonTime allows you to change the time required to produce a middle button (allowed time period to click both buttons). 100 means 100 milliseconds (ms).
You may set it to even higher values, such as synclient EmulateMidButtonTime=500 (500ms).

I use below command for that purpose
Where m stands for setting the "mouse" and the first integer represents the "acceleration", and the second represents the "threshold".
The acceleration can be specified as an integer, or as a simple fraction, but the threshold is just an integer.
The pointer will go
accelerationtimes as fast when the device travels more thanthresholdmickeys in 10 ms, including a small transition range.For more information, you can refer to the xset manual.
