I have a Raspberry pi B, and downloaded and installed "2012-10-28-wheezy-raspbian.img." I am using a 3.5 inch VGA TFT-LCD monitor, where the tiny font was hard to read, but I have managed to increase it (thanks to recantha, who answered my question "how") using "setfont /usr/share/consolefonts/Lat15-TerminusBold20x10.psf.gz". But now there is a letter missing on any line that reaches the right hand edge of the screen. I believe I should amend "/boot/config.txt" to correct this but I do not have that file, although all references suggest it should be there already.
At first I could not find out how to turn the thing off, and I thought that unplugging it may have corrupted things, so I have just downloaded the .img and flashed the SD card again. Two things puzzle me: I still do not have a "/boot/config.txt" file; and the font came up big and bold, whereas I would have expected it to go back to the original size, so where was that information carried over the re-installation?
I'm still floundering, any help would be much appreciated.
