Bloody hell - I was just going to post about this - 1.0-8174 buggered up my fonts.
After reading up, I found a solution, but first, from xorg.log:
(WW) NVIDIA(0): No size information available in CRT-0's EDID; cannot compute
(WW) NVIDIA(0): DPI from EDID.
(==) NVIDIA(0): DPI set to (75, 75); computed from built-in default
The quick fix is to start X with, like,:
> startx -- -dpi 90
Although I don't know how to calculate the correct dpi for my system?
