Mac external Monitor Panic problem

One day the Mac notebook to the external monitor, a few clicks of the mouse, resulting in a Mac crash. Later, multiple external monitors are in a panic state. Check a lot of Chinese posts do not know why, and finally the English search to find the solution as follows:

Open up Terminal

If you is using 10.6 and higher

sudo kextunload/system/library/extensions/insomniat.kext
sudo rm-rf/system/library/extensions/insomniat.kext

If you is using 10.5 and higher

sudo kextunload "/system/library/extensions/insomniat (10.5). Kext"
sudo rm-rf "/system/library/extensions/insomniat (10.5). Kext"

If you had the old app

sudo rm-rf/application/utilities/insomniat.app

To remove the Preference pane and command line client and Uninstaller

sudo rm-rf/library/preferencepanes/insomniatpref.prefpane
sudo rm-rf/usr/local/bin/insomniat
sudo rm-rf/usr/local/bin/uninstallinsomniat.sh

Go to System Preferences, right click on Insomniat and choose to remove the Preference pane.

Although I do not understand why, but the implementation ofsudo rm-rf/system/library/extensions/Insomniat.after kext, it did resolve the problem of external monitor crash.
