Description Ruben Kelevra 2014-02-22 18:02:24 UTC 
Booting&login with 19" Display, plug-in an 7" one and plug-off the 19" one.

After that the screen-scale, means icons, bars, textsize etc. is the very small on the 7" display.

But when I start gnome-tweak-tool and select another scale-factor, the screen are magically newly detected and when I switch back to 1.0 everything appears like booted&login with the 7" display. So there seems no update-routing for screen-changes.

Both Displays have the same resolution, both displays are detected via XServer as the same size, so Gnome seems to detect the screensize on other things than XServer-Informations, see Bug #724960.

The gnome-settings-daemon xsettings plugin needs to connect to the ::monitors-changed signal of the screen and when that is emitted update_xft_settings(), so that the window scale can be recomputed.

might be nice to fix for 3.12, so we can have a more functional hi-dpi support
Comment 3 Bastien Nocera 2014-03-06 13:08:30 UTC 
It would have been nice to fix it for 3.10...
