DPI

I asked about fixing DPI in 12.04.

The 14.04 release notes list "Support for High-DPI screens and desktop scaling."

Post upgrade, it seems that nothing has changed. Similar symptoms from my previous post persist:

The 1" square here is closer to 1/2"
Despite the line xserver-command=X -dpi 170 in /etc/lightdm/lightdm.conf, xdpyinfo reports 96x96 dpi

I did find that I was able to use the "Scale for menu and title bars" slider in System Settings>Displays to fix title bar text size instead of setting org.gnome.desktop.interface text-scaling-factor as described here.

The last post also mentions that in Gnome 3, DPI is hard coded to 96. Is this a limitation in 14.04? (I am somewhat ignorant to the distinction between Gnome and Unity) Can I do anything to properly set my DPI?
