Attempted to perform an Ebay search in Chrome. Machine stalled. Only mouse movement possible with cursor jammed as text-entry. Otherwise completely locked up. After several minutes, on advise of lobby IRC terminal, went to hard reboot. Holding power button unjammed machine to reboot options. Selected restart.

On restart an automatic disk-check was performed with no apparent errors. However when graphical startup began it gave an error that video hardware could not be properly configured. Selected to continue in basic graphics mode. Machine started with desktop cloned across both monitors, not shared.

Installed KeepassX to allow me to update logbook.

Second monitor wasn't set up, added it to xorg.conf as a second X Screen (this will allow for disconnections w/o affecting Screen0). Noticed that attempting to restart X lead to it hitting 100% and hanging. Killed it, and kdm brought it up okay the next time & for a re-test. Should be okay on reboot (didn't test this). Gnome didn't handle a screen stretched across the two screens well (lacking Xinerama support?), which is why I went with the two-XScreen approach.
