loss of screen resolution

["Kleene, Steven (kleenesj)" <kleenesj@UCMAIL.UC.EDU>]

Out of the blue today, my usual screen resolution (1920x1200) became
unavailable.  I booted to the console and called startx, which brings up
fvwm.  But my default base window went way off-screen, and the type was huge.
xrandr said I was at 1024x768 and did not list the 1920x1200 option at all.
(It usually does.)  I was able to define and call that option in my base
window with:

xrandr --newmode "1920x1200_60.00"  193.25  1920 2056 2256 2592  1200 1203 1209 1245 -hsync +vsync
xrandr --addmode VGA-1 1920x1200_60.00
xrandr --output VGA-1 --mode 1920x1200_60.00

This gave me my usual window and font size, but there are some side issues
(e.g. where icons go when I minimize them).

In any case, I think the problem is upstream of X windows.  I boot to a
console, and the font there was much bigger than usual.  Where is that
controlled?  Any idea how to get this back to normal?  The monitor is set to
an aspect ratio of 16:1.  Resetting the monitor and rebooting did not fix
the problem.

Thanks.
