You just didn't format that rm -rf properly, Bass.
It should be:
rm -rf "real life"
Sorry, just couldn't resist...
And for something maybe even useful:
I've had my resolution limited to 640x480 and 320x240 when my monitor is powered off. I just reboot with the monitor powered on to get all the resolutions back. This has happened when the monitor is powered off when I start the machine, and when the monitor was powered off while running.
Since rebooting solves it, I've never bothered to look further into it. This machine is my daughter's karaoke machine, with a 500Mhz P3 and a 32MB GeForce MX card and NVidia drivers.
