The touchscreen monitor I'm using for my Raspberry Pi is about 150 DPI (1280x800 @ 10"). Such high dpi is hard to work with with a touch interface. I'd like to increase the DPI such that text is rendered larger and that the QT UI I'm programming will use larger buttons (etc).
I've tried a couple things, including using
xrandr --dpi and adding
Xft.dpi: 150 to
~/.Xdefaults. Neither of these things have made a difference.
I'm using the default LXDE window manager.
What do I need to do to increase the DPI?
Edit: solution is to use ~/.Xresources instead of ~/.Xdefaults. A symlink solves this easily enough.
