My Sempron 2800+ motherboard does not have onboard video. Presumably, yours
has some sort of NVidia? Which (lspci | grep VGA output)?

Exactly what resolution is it using? With what brand/model/size display? What
does

or http://fm.no-ip.com/Auth/dpi-screen-window.html report for DPI and
resolution? What is the output from 'xrdb -query | grep dpi', if any? If
Xft.dpi is set to 96, you need to make it go away, either null, or set to a
value that makes your fonts nice size.

Which display driver is being used? NVidia proprietary? Nouveau? Other?

14.04 uses KDE 4.13.3, which uses KScreen instead of KRandr for manipulating
video settings. KScreen ignores any attempts to obey any /etc/X11/xorg.conf*
settings unless you disable it. I disable it thus via kdedrc:

	[Module-kscreen]
	autoload=false

Once you can get xorg.conf to be obeyed you can not only use it to set
whatever resolution you want, it can also force DPI to a value matching your
screen (via DisplaySize[1]), or higher, which will enlarge everything,
including fonts.
