Force Resolution of 4K monitor to 1920x1080 in lenovo laptop
good morning guys
I need your help because of my lack of experience. We have a laptop with 4K monitor on which we have just installed in dual boot ubuntu 14.04 and Windows. The problem is that the resolution at which UBUNTU start is too high, and even modifying in the desktop environment
to the next restart it start with the same high resolution (3480x2160)
Among other things, if we change the resolution of the graphic environment (Unity) to 1920x1080 all of the terminals remain with ultra-high resolution (3480x2160)
Could you tell me if there is some tips to force the resolution in the graphical environment and in the terminal environemt to 1920x1080 terminal because otherwise it's really difficult to work.
