    to accomplish this, you will need to install the guest addons. Once you have installed these, the maximum resolution you can work with is higher than your stated screewn resolution (can't remember the exact numbers)

    Also - if this doesn't fix it, you may need to allocate more memory to the virtual vidseo card assigned to your VM.

    Hope this helps,

    virtualbox - how to increase resolution of linux virtual box guest
  • user155695

    I've got ubuntu installed on virtual box, on a windows7 host

    The default resolution for ubuntu is 800 x 600, how can I increase this?

    My windows7 resolution is high, this makes my virtual box window very small and difficult to use

    On ubuntu, I can't seem to find a way to increase the resolution, I only have choice of 800 x 600

    Do I need to install some drivers?

    You need to be sure to have the guest additions installed, and to do that it is best to install the dynamic kernel module support (dkms) package first. From a terminal / command prompt:

    sudo apt-get install dkms

    Once that has been installed, you can mount the guest additions ISO and run the installer script, reboot and you should be able to adjust the resolution, run in seamless mode, etc:

    sudo /media/VBOX*/VBoxLinuxAdditions.run

    There are some additional ideas and advice given on the Ubuntu StackExchange site:

    Use xrandr in your guest, In your case "ubuntu" BUT PAY ATTETION in a "BRAND NEW TERMINAL"

    Example:

    $  xrandr -q


Screen 0: minimum 64 x 64, current 3200 x 900, maximum 32000 x 32000
VBOX0 connected 1600x900+0+0 0mm x 0mm
   1600x900       60.0*+
   1600x1200      60.0  
   1440x1050      60.0  
   1280x960       60.0  
   1024x768       60.0  
   800x600        60.0  
   640x480        60.0  
VBOX1 connected 1600x900+1600+0 0mm x 0mm
   1600x900       60.0*+
   1600x1200      60.0  
   1440x1050      60.0  
   1280x960       60.0  
   1024x768       60.0  
   800x600        60.0  
   640x480        60.0

    As you can see I dont have 1920x1280 so I did:

    xrandr --newmode "1920x1280" 60.0 1920 1600 1600 1440 1280 1024 800 640 -hsync +vsync

    and now ...

    xrandr --output VBOX1 --mode 1920x1280

    and now ...

    $ xrandr -q


Screen 0: minimum 64 x 64, current 3520 x 1280, maximum 32000 x 32000
VBOX0 connected 1600x900+0+0 0mm x 0mm
   1600x900       60.0*+
   1600x1200      60.0  
   1440x1050      60.0  
   1280x960       60.0  
   1024x768       60.0  
   800x600        60.0  
   640x480        60.0  
VBOX1 connected 1920x1280+1600+0 0mm x 0mm
   1920x1280      60.0 +   65.1* 
   1600x1200      60.0  
   1440x1050      60.0  
   1280x960       60.0  
   1024x768       60.0  
   800x600        60.0  
   640x480        60.0

    Make sure your "host" have resolution to your VBOX1.
