Bug Description

Ubuntu gnome 17.04, gnome 3.24. On high resolution display, 3200x1800, login screen is too tiny to read. GDM login screen doesn't reflect changes to org.gnome.desktop.interface scaling-factor or text-scaling-factor.

xhost +SI:localuser:gdm
sudo su gdm -s /bin/bash
gsettings set org.gnome.desktop.interface scaling-factor 2
gsettings set org.gnome.desktop.interface text-scaling-factor 2.0

no effect.

Creating a gdm user under /etc/dconf and running dconf update has no effect either. Scaling-factor seems to scale the mouse cursor, but nothing else.

OP here, I installed the 4 packages here: (change log has that patch)

However the issue still persists. On startup, everything is still tiny. Large text button still does nothing.

jefferson9, please don't install packages built for artful (Ubuntu 17.10) on your zesty (Ubuntu 17.04) install. Here's how I recommend getting back to the zesty packages. The gnome-settings-daemon-dev and gnome-settings-daemon-dbgsym packages are not in the default install and aren't needed by most people (but it's fine to keep them installed if you think you want them).

sudo apt remove gnome-settings-daemon-dev gnome-settings-daemon-dbgsym
sudo apt install gnome-settings-daemon/zesty gnome-settings-daemon-schemas/zesty

There was a mistake in the artful upload so I uploaded a new version now.

This week, there is another gnome-settings-daemon Stable Release Update (LP: #1682132) that was already accepted into zesty-proposed for testing before the fix for this bug was pushed into gnome-settings-daemon's git repository. After that previous fix is verified and pushed into zesty-updates, we can work on getting this bug fixed into zesty too.

Okay, before reverting out of curiousity I did try the recently updates packages and can confirm the issue is resolved, and everything seems stable, no regressions.
