Unable to use long press
I'm trying to place a widget on my homescreen, but have been unable so far because long press doesn't seem to work. When I hold down the left mouse button on the homescreen nothing happens. I can get around this by opening the context menu with ctrl + esc. However, dragging a widget to the homescreen from the widget menu is still impossible.
To be clear: I'm using a wireless keyboard and touchpad as my input device. The setup does not have a touch screen.
