I love Linux Mint but a frustration of mine is the fact that the mouse cursors are inconsistent. If you change the mouse theme in the themes settings it will change for most windows, but certain windows such as chrome or wine revert to the system default mouse cursor.
I’ve finally found a fix courtesy of Ubuntu Forums. The problem lies with the x-cursor-theme being independent of the theme set in cinnamon. What you have to do is run a command to update the x-cursor-theme.
First, find the name of the mouse cursor you want from a list of your installed themes:
Set an environment variable of the theme you want. Specify the folder name of the theme. For example, for DMZ-Black cursor:
Lastly run the command to update your cursor:
gsettings set org.gnome.desktop.interface cursor-theme "$CURSOR" && sudo update-alternatives --set x-cursor-theme /usr/share/icons/$CURSOR/cursor.theme
That’s it! You now have consistent mouse cursors. OCD demons satisfied.
