Arch Linux KDE: How do I get the mouse pointer / cursor to highlight?

Question

I'm running a current version of Arch Linux (KDE) on a Dell laptop.

When I press the Meta key (with the Microsoft logo) it brings up the application launcher menu+. So it's not a dead key. And Ctrl works as expected.

However, Ctrl+Meta does not highlight the pointer / cursor position, nor does clicking the mouse animate anything, despite having both "Mouse Click Animation" and "Track Mouse" checked in the Systems Settings / Desktop Effects configuration, and confirming that the key binding for "Track Mouse" has both "Ctrl" and "Meta" checked.

I tried a variety of other finger-yoga contortions, but was unable to locate whatever magic combination would work.

Is there some common application or setting that might be overriding the above? (I don't believe I'm running anything especially peculiar enough to override KDE / Plasma.0

Solution 1

I use KDE version 5.6 and in order for mouse tracking to work I actually need to do the following:

• Go to the System settings.
• search "Track mouse", it should be in the "Desktop effects" submenu.
• Enable it by ticking the checkbox.
• Mouse over the Track mouse and then click on the "configure" which should appear as settings icon on the left.
• As shortcut, I have unchecked "meta" and everything else. Then I clicked "none" to set a shortcut. Then I pressed the F12 key. Then I clicked OK.

If it still does not work, then in System Settings, search for "compositor" and enable it. It happened to me that it was disabled automatically because it crashed.

That's it.

The screenshot is an example which uses different keys.

This is the settings screen:

Cursor is highlighted like this:

Solution 2

The default configuration on Arch/KDE5 is Ctrl+Meta keys PLUS moving the mouse cursor. This may appear somewhat unintuitive, particularly for users coming from other GUIs (like Ubuntu 16 with Gnome) where just a modifier key press alone shows a pointer animation already with no mouse action required; also, for physically handicapped users it may be easier to activate than KDE's approach.

Solution 3

To make the cursor more visible:

---

KDE menu

• settings

• system settings

• workspace behavior

• desktop effects

• (check the option:) track mouse

• (hover over "track mouse" to let the two buttons appear on the rightmost side)

• (click the button which shows the "configure" tooltip)

• (uncheck all the "modifier keys", which in my tests were ignored anyway)

• none

• (press a key of your choice; I chose the F12 function key)

• OK

---

Now close "system settings" and if it asks "apply, discard, cancel" then click "apply".

Press the F12 function key to activate or deactivate the effect.

If it still does not work, then do as follows:

---

KDE menu

• settings

• system settings

• display and monitor

• compositor

• (check:) enable compositor on startup

• (log out and log in, or just reboot)

---

It happened to me that it was disabled automatically because the graphics driver crashed.

The default keys to activate this on my Arch distro is meta+*, not meta+ctrl. If i change to ctrl+meta it doesn't work. Try another combo?

Just using two modifier keys won't do anything. Combine one or more modifier keys with a "normal key". It's meta+* for me as well on Kubuntu 18.04.

Both answers helped: meta-* toggles the mouse animation, which I didn't know I needed to toggle on. The default for "track" didn't work with any meta+[x] and I had to switch to alt+/. Thank ye both.

How is this different than the existing answer unix.stackexchange.com/a/570608 ?

@guntbert Indeed I first posted this as an edit to the answer that you mention, but it wasn't published.
