I upgraded Ubuntu to Ubuntu 20.04.3 LTS. My current version GNOME 3.36.8, and the windowing system is X11. My Gnome Terminal version is 3.36.2.
Before the upgrade selecting text in the Gnome terminal copied the text to a buffer/clipboard that could be pasted into any desktop application.
After the upgrade, selecting text in the Gnome terminal does not copy the text to the (X11? Gnome? other?) clipboard. I have to press ctrl+shift+c to copy the text.
How do I restore copy-on-select functionality?
