Touchpad double-click timing in Xfce

Lysander666 · 11-09-2019, 06:20 AM

One of the things that occasionally drives me mad in Xfce is the double-click tapping on the touchpad. I want to extend the time between taps for the double click but I can't find out how to do so.

Under "mouse and touchpad" "behaviour" settings there is an option for double-click behaviour but this only seems to apply to the mouse buttons, not the touchpad.

Is there a way of extended the time between taps on the touchpad which count as a double-click?

Have you tried flsynclient? There is a double click slider on the Tapper tab.

^ Somebody recently here on LQ had immense trouble getting that to work.
I'd just use the command line options for synclient.
But, L666, do you even have a synaptics touchpad?
What is the output of

Code:

xinput
# and then use the ID of your touchpad
xinput list ID

?
Once that is established, I'd like to move on to help you set it up via command line.

Thanks to both of you. Installing and setting up flSynclient was no issue. I think the problem is not, on reflection, necessarily related to double tap time, but to the sensitivity of the touchpad, which I have now reduced. I'll see if that has any effect.

ondoho, in answer to your query:

The weird problem I'm having now - which I've also had for a while, is double-clicking doesn't work at all in GTK-based applications. For instance I can highlight text/select something in a browser or notepad with no issue, but when adding an attachment to an email, whereby the browser opens the 'select' window in GTK, I cannot select any file by double clicking, though using 'return/enter' does work. It's not a huge issue but I would love to know the cause if anyone has any ideas.

Do you mean double-clicking or double-tapping? please be precise.
I have not yet come across a touchpad that had no physical click-buttons at all (they may be integrated in the touchpad, appearing invisible, but they're there).

In any case it seems your ALPS clickpad might benefit from using synaptics drivers instead of libinput.
No idea how slackware handles these things, but this article should help.

I mean double-clicking and double-tapping in this case. I tried it with both, neither works in GTK. I'll have a look at those articles and see if I can improve anything through them, thank you.
