H/V expand is the option that sets the display behaviour when the
received display XY size is < real LCD XY size. If H/V is on,
then the display chipset attempts to stretch the display it gets
out over the real display, using a weird antialiasing type thingy
to handle the fact that there isn't a 1 : 1 or even necessarily
a (1 : integer x integer) relationship between the logical and
physical displays. iyswim. If it's off, the chipset just uses a
small area in the center of the display whose XY dimensions match
the XY dimensions of the logical display.
I've got a couple of weird problems with my A20p myself - I left the laptop
plugged in and on for a while once (a few days) with the lid down,
suspended - it came back on with the display hosed and the keyboard locked
up - but I could ssh in and thwack X hard (init.d restart of gdm).
So I experimented and left it on, plugged in and _not_ suspended for a
similar period of time: same result - machine responded over the ntwork,
local access hosed - and when I suspended it, it refused to wake back up at
all till I lened on the power button and sat through a fsck. Also, if I
leave it in hibernation for > 1 hour(ish), it locks up the next time I
come back up (if I come back into X) or the next time I leave X (if I flip
to the console before starting hibernation).
