@corey wood - I can confirm your finding.
I did this:
1. scale to 200%
2. reboot - the login screen shows
3- login --> screen power save mode happens
4. ctrl-alt-3 and then log in at the console
5. Change "" from 2 to 1 in ~/.config/monitors.xml
6. ctrl-alt-2 to switch back to graphical
@sebastian Heiden:
I have no problem using scaling at 200%. Opening applications is working,
gthumb is working fine for instance. I have switched back and forth, and is
writing this in chrome at 200%.
gnome-control-center is acting a bit wierd when:
1. at scaling=200%, open
I also have a similar issue with scale set to 200%. The screen does not
go blank after applying the 200% scaling and things seem to work as
expected, but when logging in after a reboot the monitor goes into
power-save state. So it doesn't appear to be specific to fractional
scaling, since 2x
Have you tried setting the screen scaling factor to 200% without
fractional scaling enabled? I am experiencing a pretty similar issue in

I tried this with a NVIDIA graphics card, and surely enough, the bug is
present. With my AMDGPU system it doesn't happen.
