I have a NVIDIA GeForce 8400 GS video card and running Ubuntu 12.04.4 with all its updates. I use this same version on a laptop and do not have this problem but I also run it on a Dell Optiplex with on-board intel video and it has the same problem. What is the Problem? The sidebar and top menus are off screen. I don't know how I can use Linux system/video settings to shrink the size of the desktop to fit on my screen. The PC is connected to a Panasonic TV via HDMI (The Dell to a flat screen monitor via VGA). I have used all available screen resolution settings but none do the trick. I have used the "search for additional drivers" in Settings and tried both the recommended and the latest NVIDIA drivers but that does not help either. How do I (can I) reduce, shrink the size of my desktop, so the outer borders come in so the side bar and top menus can be seen? Thank you.
