Comment 7 for bug 1700085

There is no way to adjust scaling in current Ubuntu Artful.

It has disappeared from gnome-tweaks-tool and did not get added to gnome-settings.

My suggestion for the right place for scaling is the "Displays" section of gnome-settings. There there should be a widget for entering a scaling value (non-integer) in each Display's configuration dialog (so that you can also adjust displays with different resolution to fit together).

Back to this bug report, the mouse pointer ideally gets pre-scaled by the scaling factor for the display and in the mouse settings the user can enter a scaling factor to adjust it to his needs. Could we do it this way?

As a workaround for the time being I selected the "Redglass" mouse cursor theme in gnome-tweak-tool as the (too small) red cursor is more visible than the (too small) black cursor.
