GNOME hardcode the DPI to 96 because the xorg value can't be trust, see e.g http://git.gnome.org/browse/gnome-settings-daemon/commit/?id=a49af89751057649034a42c511d2330d63bbfa6e
Not sure there is a lightdm issue there... ** Changed in: lightdm (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1060886 Title: lightdm does not pass Xserver DPI setting to gnome-session Status in “lightdm” package in Ubuntu: Confirmed Bug description: While most desktop users start gnome-session through lightdm login, lightdm does not pass DISPLAY DPI setting in /etc/X11/xorg.conf to the started gnome-session. I can see relative keywords in /var/log/Xorg.0.log indicating DPI setting is adopted by Xserver, and I see big font size in the unity-greeter interface indicating larger DPI setting in xorg.conf take effects. However inside the desktop, DPI is reset to default (96,96) with no reason. Further I use xrandr to set DPI to a larger value but see no effect. Using xpdyinfo shows DPI is still (96,96). So does gnome just abandoned the display dpi feature in the application level? or is it mandatory to set dpi always to (96,96) by gnome?
