Re: [lubuntu-users] Keyboard shortcuts (for touchpad enable/disable)

[Mark F]

Israel, I had the same reaction to Basil's suggestion. But, I overlooked
how he said a value of zero means "touchpad off." I think that would
satisfy resource sensitive people (the target audience of Lubuntu?).

If I'm not using a real mouse (and needed the touchpad), reducing its
sensitivity while typing would be a blessing. Maybe it's just me, but my
mouse cursor (and focus) are *all over the place* while I type with the
touchpad on. I can't get anything done. I prefer an external mouse (and
touchpad off). But, sometimes it's handy to use the touchpad than to lug a
mouse around with you.

My thing is: I wish it could be a UI in the menu->preferences/settings.
Then new users would have a reasonable chance of finding it. But, I know
that adds to someone's work.

There is a touchpad-indicator[1] package (with a UI, sits in the taskbar).

Any takers?

Hi Basil,
This would be an OK idea, and easy to implement, but the issue you run 
into is having a near continual 'sleep' going, which eats memory.
You could write a program to do this but I think a touchpad toggle 
script is easier, and makes more sense, as well as saves your resources:


#!/bin/bash
CURRENT=$(synclient |grep TouchpadOff)
# get the current touchpadoff value... 0 is on 1 is off
if [[ "${CURRENT/0}" != "$CURRENT" ]]
then
  #  touchpad is on, so turn it off
  synclient TouchpadOff=1
else
  # touchpad is off, so  turn it on
  synclient TouchpadOff=0
fi

Just simply make this an executable file and edit your openbox config 
file to make a shortcut to run this script
It is simple and easy.  It automatically turns it off OR on depending on 
the current state.

Upon further reflection, that could be because I don't make use of any
keyboard shortcuts on a regular basis. Maybe if I were in the habit of
hitting various key combos I could empathize with Aere's caution.

But, it seems like that would happen with any keyboard shortcut. I've been
using ctrl+alt+f1 to bring up a console (then ctrl+alt+fn+f7) to go back to
the desktop (a workaround for the mouse cursor disappearing after
locking/unlocking the screen). If I accidentally hit that, I would know how
to undo it.

I can see how, if someone didn't know of the shortcut they could cause
Aere's situation to arise.

But, It's possible I could hit a different key (in the scenario I described
above) and get something I wouldn't know how to get out of. It's not like
the touchpad scenario doesn't already exist(?) in other ways.

A solution would be if the on/off toggle were a GUI under menu-settings,
and the shortcut could be enabled/disabled there? Then the user would have
a reasonable expectation of knowing about the shortcut if someday they
accidentally toggled the touchpad.

About the documentation of keyboard shortcuts, I often wish Lubuntu had a
"Welcome" screen after installation, like Mint does. Things like keyboard
shortcuts could fit there. I'm sure experienced users think that would be
lame. But, the way Windows is becoming controversial with its users, it
seems to me like it would be good to have the basics presented to new
users. It's not that bad to check "Don't show me again."
