HiDPI settings reset on logout

Bug Description

When logging in to my XPS 13 (9360) on 17.10, the only thing that is reasonably (200%) scaled is the sidebar. Top bar, windows, and fonts are all unscaled and TINY.

- I'll go to Control Centre, Devices, Displays, and see that scaling is set to 200%.
- I'll then change the scaling to 100%, and hit apply and confirm. At this point, windows are scaled to 200%.
- I need to change the scaling to 100% AGAIN. Now everything is 100%, and therefore tiny
- I then change the scaling to 200%, hit apply and confirm, which does barely anything
- I then need to set scaling to 200% AGAIN, hit apply and confirm, and only *then* everything is properly scaled.

I need to do this every time I log back in.

Fixed in gnome 3.26 for me.

I switched to Wayland by enabling modesetting (for KMS) in nvidia drivers and the scale persists after a reboot when using Wayland instead of Xorg.

Even though a fix was released in september I started having this problem a few weeks ago, so since December.

Fresh Ubuntu 17.10 has the issue of showing Qt apps non-scaled. Should we reopen this issue or continue in https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1713323 , or make a new one? What's the way to go?
