[Pkg-xfce-devel] Bug#813379: xfce4-settings: Please also set DPI via RandR extension

[Thomas Prokosch]

Package: xfce4-settings
Version: 4.12.0-2
Severity: minor
Tags: upstream

XFCE comes with a configuration setting for adjusting the DPI of a
monitor. However, this setting only has effects on Gtk, X itself is
not affected. You can easily check this by selecting a non-default DPI
setting in the XFCE settings manager, and then at the command line
execute:

   xdpyinfo | grep resolution

This will display the default resolution, chosen by X itself. However,
some graphics hardware is broken and report a resolution of 96x96 dpi,
even if this is clearly not the case. The old approach was to edit the
xorg.conf file to add the relevant properties. However, this approach
is deprecated. Another possibility is to use xrandr similar to

   xrandr --dpi 280

It would be nice if XFCE also changed the RandR DPI setting (not only
the Gtk DPI setting) to make this command line trickery unnecessary.

Thomas
