You change monitors on your linux system and next thing you know you get a Frequency out of Range error on the monitor.  Well for my latest CentOS fix I found that a CTRL-ALT-F1 dropped me to the command line, then a "system-config-display --reconfig" did wondors for the system.  Kudos to sandgroper and Matt Lawrence for these posts:
