i am using the latest raspbian for robots, and have just found that when I am not using VNC but have my pi connected to a monitor I cannot install software using the preferences-> Add/Remove software. I click on a tick box, click ok, its says its installing (but never asks for a password), it completes really quickly, far quicker than expected. Then there is nothing installed… If I do the same via VNC then I do get a password request and all works as it should…
Could any one suggest what is happening. I am on a vanilla install, nothing is changed from the original image as downloaded.
