I have windows installed on my laptop, which is also hooked up to a larger Samsung display. It works perfectly on Windows, but once I installed Ubuntu on my laptop, I couldn't figure out how to hook it up to the display like I had done in Windows. A couple times when I booted Ubuntu and had my Samsung monitor on since I had just been using Windows, it would flash with the loading screen for Ubuntu on my monitor for a few seconds, which confused me even more. Please help!!!!
