I can confirm that including gnome3-staging solves most of my HiDPI issues.
Nearly everything seems to work now, according to the setting in the control panel -> peripherals -> display tab. I don't know what that is exposing in gsettings (if it is); nothing obvious. It's certainly *not* org.gnome.desktop.interface scaling-factor, which is unaffected by that control. But it is working for me. What still doesn't work: * Java9 JavaFX, which is still apparently getting its idea of scale purely from org.gnome.desktop.interface scaling-factor and works according to that setting. That's their bug, presumably. * QT apps like nextcloud-client may still have issues. When launched at login it still shows small fonts, but when relaunched later, it's fine. Little wrinkle. It might be the difference between the mysterious new setting being at a default-autodetect state, and being set deliberately to 200% now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1713323 Title: HiDPI support partially broken after upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1713323/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
