I've looked at gnome-settings-daemon code and AFAIR those reasons are: 1. Have DPI at least 192, and 2. Have vertical resolution at least 1200. Relevant code: https://github.com/GNOME/gnome-settings-daemon/blob/master/plugins/xsettings/gsd-xsettings-manager.c#L233-L241 #define DPI_FALLBACK 96 /* The minimum resolution at which we turn on a window-scale of 2 */ #define HIDPI_LIMIT (DPI_FALLBACK * 2) /* The minimum screen height at which we turn on a window-scale of 2; * below this there just isn't enough vertical real estate for GNOME * apps to work, and it's better to just be tiny */ #define HIDPI_MIN_HEIGHT 1200 There is also lengthy comment about it. Anyway the above looks reasonable for me for automatically turning HiDPI mode on. So, if it was incorrect, I'd guess something gone wrong with retrieving input values (DPI, vertical resolution). - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.
