Well, Kevin's framing of this is clearly...opionated...:) but my blog post gave the citation. https://www.happyassassin.net/2015/07/09/of-dpis-desktops-and-toolkits/ https://cgit.freedesktop.org/xorg/xserver/tree/hw/xfree86/modes/xf86RandR12.c#n787 as my post explained: "As you can see there are basically three paths: one if monitorResolution is set, one if output->conf_monitor->mon_width and output->conf_monitor->mon_height are set, and a fallback if neither of those are true. monitorResolution is set if the Xorg binary was called with the -dpi parameter. mon_width and mon_height are set if some X config file or another contains the DisplaySize parameter. If you specified a dpi on the command line, X will figure out whatever ‘physical size’ would result in that DPI for the resolution that’s in use, and claim that the screen is that size. If you specify a size with the DisplaySize parameter, X just uses that. And if neither of those is true, X will pick a physical size based on a built-in default DPI, which is...96." -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org
