Monitor resoluton

[Brian Cluff]

When you get your monitor to show the correct resolution again, I would 
suggest that you never turn off your monitor, unless you also turn off 
your computer.  Instead, set your power management to put your monitor 
to sleep.
If you turn your monitor off while your system is still on, your system 
assumes that it has no monitors at all and when you turn the monitor 
back on it treats it like you are hot plugging a new display on your 
system and configures it from scratch, hence the changed resolution.  If 
your monitor is asleep, it will continue to tell your computer that it's 
still there so your random config changes won't happen.

If you want a way to suspend your monitor immediately, create an icon 
that runs this command:

xset dpms force standby

Alternatively you could hard code your monitor into the X11 settings so 
that it always knows it's there... but I wouldn't recommend that.
