How do I change my monitor's resolution when working in a virtual terminal?

When using a virtual terminal with an external monitor, I would like to set the resolution to the monitors optimal resolution, but I'm not sure how. Does anyone know how I would go about doing this?

virtual-terminal

    run hwinfo --framebuffer

    and you will get a short or long list depending on what video card you have. The list will look something like this:

    Mode 0x0335: 320×240 (+640), 16 bits
Mode 0x0336: 320×240 (+1280), 24 bits
Mode 0x033d: 640×400 (+1280), 16 bits
Mode 0x033e: 640×400 (+2560), 24 bits
Mode 0x0345: 1600×1200 (+1600), 8 bits
Mode 0x0346: 1600×1200 (+3200), 16 bits
Mode 0x0347: 1400×1050 (+1400), 8 bits
Mode 0x0348: 1400×1050 (+2800), 16 bits
Mode 0x0349: 1400×1050 (+5600), 24 bits

    Then you take the Hex value to the right, for example 0x0346 and you write it down.

    edit /etc/default/grub

    the line that has ="quiet", make it "quiet vga=0x0346"

    then you have to run> sudo update-grub

    reboot the machine

  2. After you set up your virtual environment, you will need to install some specific hardware. If you are virtualizing a windows environment there should be an icon in the system tray on, bottom right.

    Under linux, I'm not sure where it would show up but you should see those as well.

    Without the extra install, you won't be able to get the full screen.
