7 The librem 13 v3 has 1920x1080 px resolution, on 13". This is "hidpi".
\r
9 Standard PureOS shipped had much too small fonts and icons.
\r
11 xpdyinfo reported 96 dpi resolution, which is really wrong. In reality it's 166 dpi.
\r
13 I told X11 to use the real screen size, and Cinnamon uses this information correctly (KDE, Gnome, Mate, XFCE not)::
\r
15 $ cat /etc/X11/xorg.conf.d/90-librem-display.conf
\r
16 # xdpyinfo | grep -B2 resolution
\r
17 # https://wiki.archlinux.org/index.php/xorg#Display_size_and_DPI
\r
20 DisplaySize 294 166 # In millimeters
\r
23 I also had to set "Font scaling factor" in the cinnamon font settings to 1.3

30 The traditional approach to supporting high DPI has been one where Qt scaled fonts automatically, and then provided a DPI value that application code could use to scale the rest of the UI.
