Help please. I have a LG w2452t flatron monitor, running 12.04. When my computer wakes from sleep, the screen is completely jumbled mess. Thankfully I know that behind the mess is the login dialog, so I enter my password, and the desktop screen displays. But the edges of the screen (the dock) and the top (the time, date, etc.) is completely fuzzy. I have a screenshot where you can see that the Displays box shows Laptop, and the nvidia-server settings shows my monitor, but says it is disabled. I cannot find a way to enable it. Please help. Complete noob! Thanks
