Kubuntu 20.04

Kind of like how Windows has an option one can set where hitting the CTRL key alone will create a sort of bullseye animation surrounding the mouse cursor to help locate it. Is there something similar in KDE/Kubuntu? I see nothing in the control panel relating to such. Very necessary when dealing with 3 screens.

I've found posts describing something like that for older versions of Kubuntu, and Gnome and Xubuntu. I've tried oneko, but that's a little overkill for what I need.

I'm on Kubuntu 20.04, KDE Frameworks 5.68.0

I tried
System Settings > Workspace Behavior > Desktop Effects > Accessibility > Track Mouse

In my case, it doesn't seem to do anything.
I also bound the keys Ctrl + L, it still doesn't do anything.

Hmm. Works for me. In the "[Plugins]" section of "~/.config/kwinrc", I have "trackmouseEnabled=true" and in the "[kwin]" section of "~/.config/kglobalshortcutsrc" I have "TrackMouse=Meta+Alt+M,none,Track mouse" (because I assigned Super+Alt+M as the toggle for turning mouse tracking on/off).

In some other thread you were exploring logging in as root. Maybe there's a permissions issue?

EDIT: The track mouse feature does not work for me with Plasma 5.22.90 (aka 5.23 beta). Nothing happens.

NOTE: If a desktop effect doesn't work immediately, turn compositing off and then on again. Alt+Shift+F12 is the toggle.

In my case, I had Compositor disabled since long ago, it would cause a crash when I played a certain game.
Yes, if I enable it, the mouse tracker works.
Hmmm, maybe they should make the mouse tracker work without the Compositor.

I think most, if not all, desktop effects require native compositing.

I once hacked a script that locates the mouse cursor.
No compositing required.
You can choose one of osd_cat, aosd_cat or conky to display the frame around the cursor.

Code:

#!/bin/sh

showtime=2 # in seconds
method=conky # aosd_cat or osd_cat or conky

eval $(xdotool getmouselocation --shell)

# get cursor size to calculate offsets
#~ gsettings get org.gnome.desktop.interface cursor-size

case "$method" in
osd_cat)

printf "██████████\n██      ██\n██      ██\n██      ██\n██████████" | osd_cat -o$((Y-20)) -i$((X-35)) -d"$showtime"

;;

aosd_cat)

font="monospace 60"
X="$((X - 20))"
Y="$((Y - 40))"
color="#00FFFF"
#~ string="◊"
string="O"
showtime="$((showtime*1000))"
printf "%s" "$string" | \
aosd_cat --position 0 -x "$X" -y "$Y" --font "$font" --fade-in 0 --fade-full "$showtime" --fade-out 0 --shadow-opacity 0 --fore-color "$color"

;;

conky)

cat <<EOF | conky -c - & conkypid=$!
conky.config = {
own_window = true,
own_window_transparent = false,
own_window_colour = '#ff0000',
own_window_hints = 'undecorated,skip_taskbar,skip_pager,sticky',
update_interval = 1,
double_buffer = true,
minimum_width = 20,
minimum_height = 20,
maximum_width = 20,
alignment = 'top_left',
gap_x = $X,
gap_y = $Y,
draw_borders = true,
draw_outline = false,
draw_shades = false,
border_width = 4,
border_outer_margin = 2,
default_color = '#ffffff',
};
conky.text = [[]];
EOF
# total_run_times is unreliable, therefore:
sleep "$showtime"
kill $conkypid
