My mouse pointer became invisible after some updates after I upgraded to 15.04 from 14.10.
In all standard settings the mouse pointer is activated (system settings, dconf…)
I also tried different cursor icons with no success.
The pointer is sometimes visible after I shut down and reboot the system. But only sometimes and I couldn't figure out a patterns why it sometimes shows up.
I found the following solution which did not work
gsettings set org.gnome.settings-daemon.plugins.cursor active false
Any help appreciated! thanks!
