I was needing to highlight the mouse cursor for a presentation. I found this really nice cursor theme.
It shows a transparent aqua/blue/dark/red/… circle around the cursor. I chose the red theme. I installed it on awesome window manager. It’s very simple to install, just download the tarball and do the commands:
# cd /tmp
# tar xvf 160115-bDMZT.tar.gz
# mv bDMZT/rbDMZ /usr/share/icons
# cd /etc/alternatives
# rm x-cursor-theme
# ln -s /usr/share/icons/rbDMZ/cursor.theme x-cursor-theme
echo "Now reboot or stop and start the xorg"
