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.

Can you post xorg.cfg?
If it does exist.

Tomorrow i'll be at work and i will post the XORG.conf

In this config file, you can set the resolution for your screens.

i was trying to look the xorg.conf in a virtual machine in my Laptop and seems that this file it does not exist anymore? is possible?

This is possible.

Then you have to create it and set the resolution to your needs.

Finally i'm at work and i can be more precise about the problem i have because i made some error describing the problem sorry...

In Graphic Environment(Unity) i have configured the Display to 1920x1080 and the configuration remain also in the restart and is good also for the terminal.

The Problem remain in the TTY1-7 and in the logon Windows. In the Logon Windows is a relative problem, even if i would like to fix, because you have to insert only the password but in the TTY enviroment is impossible to work because of the high resolution.

I have to install NVIDIA Driver and in order to do that i have to kill the lightdm service and work with TTY1-7 and is hard to see what i write....

I made some step forward maybe...
I have opened this file

$sudo nano /etc/default/grub

and i add this lise

GRUB_GFXMODE=1024x768

Now the Grub Menu is bigger and Readble but soon as the graphical mode is loading is even in "4k" and the same for the terminal TTY1-7

You need to add these lines to /etc/X11/xorg.conf:

SubSection "Display"
Depth 24
Modes "1920x1080"
EndSubSection

I'm not sure I understand the problem -- can't you just make the fonts, window borders, etc. larger and carry on as "normal"?
