I find the default double click interval problematic and want to change it

I cannot see a setting in Mouse settings to do this.

I found this post from 2018 viewtopic.php?f=289&t=153755

Which refers to

Code: Select all

/etc/X11/xorg.conf
/etc/X11/xorg.conf.d/xorg.conf

But I do not have these files on my PC

Code: Select all

Operating System: KDE neon 5.25
KDE Plasma Version: 5.25.4
KDE Frameworks Version: 5.96.0
Qt Version: 5.15.5
Kernel Version: 5.15.0-46-generic (64-bit)

Could anyone advise how to do this?

[edit] I did try to create both files with the suggested text above.

I also installed the package

Code: Select all

xserver-xorg-input-evdev

But do not have the advanced controls after reboot.

You have installed xserver-xorg-input-evdev, so you have half of the problem resolved.
There is no xorg.conf on KDE Neon, you have to create it.
That file is on a sensitive location, that means that you need root privileges to write on the /etc folder (that's where global configurations are placed).
You have two options. The first is login as root and create the file within the terminal:

Code: Select all

su
cat > /etc/X11/xorg.conf << EOF
Section "InputClass"
    Identifier "evdev-mouse"
    MatchIsPointer "yes"
    Driver "evdev"
EndSection
EOF
exit


The second, as a user with privileges (the default user on KDE Neon), create the file with Nano.

Code: Select all

sudo nano -w -l /etc/X11/xorg.conf

Append the same lines as the first option:

Code: Select all

Section "InputClass"
    Identifier "evdev-mouse"
    MatchIsPointer "yes"
    Driver "evdev"
EndSection

And save the changes.
After creating the file, reboot and you should have the advance settings on

Code: Select all

System Settings -> Hardware -> Input Devices -> Mouse

Noting here figured out a fix in case its helpful to someone else w this problem.

installed xserver-xorg-input-synaptics

On reboot the advanced setting were there.

Why these settings arent in KDE to start with is completely beyond me TBQH. They are fundamentally basic controls to user experience using a mouse with a DE.

For what I know, KDE Neon is used by KDE developers to test the code. Maybe they just keep the basic stuff.
