Fix for ubuntu 14.10 screen resolution issue on Virtualbox

Problem

After installing Ubuntu 14.10 guest on VirtualBox running on windows 7 host, I am stuck with 640×480 screen resolution. The ‘Detect Displays' button on the ‘Display Settings' Settings screen is not reachable, because 640×480 is too small.

Solution

Any version of VirtualBox you should install the latest version of the VirtualBox Guest Additions into your Ubuntu-Guest. You can get it from the Ubuntu-Software-Repository.Run the following command from your terminal

sudo apt-get install virtualbox-guest-dkms

After completion of the required packages you need to restart the VM now you should get the proper screen resolution

If you are running MAC OSX use the following fix (Thanks to Mr.robot)

First: sudo apt-get remove libcheese-gtk23

Then: sudo apt-get install xserver-xorg-core

Finally: sudo apt-get install -f virtualbox-guest-x11

  1. I followed your instruction but the graphical screen corrupted when I restart Ubuntu 14.10. What should I do to fix this problem?

  2. I am running ubuntu 14.04, hosted in a Virtual Box, running on a Mac Os X 10.9. The above described fix did not work for me. The resolution is still stuck at the low 640×480.

  3. Try this:

    First: sudo apt-get remove libcheese-gtk23
    Then: sudo apt-get install xserver-xorg-core
    Finally: sudo apt-get install -f virtualbox-guest-x11

    I had the same problem, it worked for me…

  4. Thank you Mr. Robot! You’re my hero! This worked like a charm!

    First: sudo apt-get remove libcheese-gtk23 + click Y to confirm + wait a while…
    Then: sudo apt-get install xserver-xorg-core + click Y to confirm
    Finally: sudo apt-get install -f virtualbox-guest-x11

    Worked for me!

  5. Looks like removing libcheese also removes the system settings. To get it back use:
    sudo apt-get install ubuntu-desktop

  6. I have a guest OS created(other linux-64 bit) in the virtual box, hosted on a Ubuntu 14.04.4 LTS. How to change the screen resolution of the guest machine?
    Thanks in advance.

  7. Though by googling I got some command to change the resolution, but it did not worked for me. However, I could find a config file in the virtual machine: /etc/modprobe.d/uvesafb.conf. By setting the desired value in this file and restarting virtual machine, resolution got changed.
