Comment 14 for bug 1870736

Mh, logging isn't too useful just give us the output of the logs, please run this before doing changes from the control center

journalctl -b0 -ef /usr/bin/gnome-shell

Then do the change from control center and give us what the has been logged.

Also, the output for (before and after, if anything changed)

xrandr --verbose

Could you also check if the command:

xrandr --output DVI-D-0 --scale 2x2
xrandr --output DVI-D-0 --scale 1.5x1.5

Does something for you?

Cheers
