I've tried following directions at
to make my Ubuntu desktop on my latest 4k desktop more readable and in turn usable.
but when doing
gsettings set org.gnome.desktop.interface scaling-factor 2
on my terminal I get a temporary magnification flash followed by a reset to normal (unusuable) rendering resolution.
I'm using Ubuntu 15.04.
What to do?
Update: According to https://www.phoronix.com/scan.php?page=news_item&px=MTYzMTM there should be "UI Scale factor" but I can't find it in the Ubuntu system settings. Where is it? Is it the same as the gsettings call mentioned above?
