When I first plugged in my 23 inch monitor through the mini-VGA port, everything worked...both display were detected, and worked.

On the second or third plug in, the internal display would turn off, and only the external display would work. When I try to 'detect monitor', I got "could not set the configuration for crtc 63" a few times.

Now, when I plug in the external display, I get a screen full of orange color on the external display, and the laptop display turns off. The only way to get things back is to force turn off the laptop and restart. Unplugging/replugging monitor doesn't work, and seems like ubuntu crashes.

Can anyone help?

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
