Comment 0 for bug 1689356

After upgrading to Ubuntu 17.04,
the HiDPI setting(Scale for menu and title bars)
is being reset to 1 everytime when display sleeps for a while,
making everything looks small.

If the display sleeps and I resume it instantly, it's fine,
but if the display slept for long, the HiDPI setting gets reset to 1.

My guess is that if a display is plugged in(detected), the old DPI setting is not restored.

This issue is not present on previous Ubuntu versions
and the same issue persists even after a fresh install.
