i changed my cursor to breeze a while ago and now i wanted to change to another cursor theme again but i couldnt make it.instead my cursor changed to an old weird theme.now i cant go back to breeze either. How to change the mouse cursor theme? i installed the theme with this guide how can i go back to elementary OS stock?
As mentioned in the steps in the thread you linked, the following commands can revert to the default cursor theme by changing the themename.
gsettings set org.gnome.desktop.interface cursor-theme elementary sudo update-alternatives --install /usr/share/icons/default/index.theme x-cursor-theme /usr/share/icons/elementary/cursor.theme 21 sudo update-alternatives --set x-cursor-theme /usr/share/icons/elementary/cursor.theme
These three commands will revert these changes. You may need to reboot for these changes to take effect.
