    Virtual Box full screen problem

    Hi,

    I'm running Ubuntu on Virtual Box and I'm not able to expand the view to full screen. I realise there are other forums discussing this problem, and they solved it by running the VBoxGuestAdditions.iso. However, I've done this already but as soon as I updated Ubuntu the screen no longer displays at full screen (1920x1080). If anyone has any ideas it would be greatly appreciated!

    Re: Virtual Box full screen problem

    When the kernel is updated, the guest additions need to be compiled into the kernel again. This is not a problem with Ubuntu. It happens with all distros when the kernels are updated.

    Simply go to the terminal and execute

    Code:
    sudo ./VBoxLinuxAdditions.run
    (or similar, depending on where the file is on your system. To make this less of a pain, I usually copy VBoxLinuxAdditions.run into my Home folder.)

    You don't need to do this for all updates, only when the kernel is updated.

    Re: Virtual Box full screen problem

    Thanks for replying so promptly!

    I've tried running the command, but I get an error back

    sudo ./VBoxLinuxAdditions.run
    sudo: ./VBoxLinuxAdditions.run: command not found

    I also copied to my home directory.

    any help?

    You will need to add the complete path to the .sh file. Mine is in my Home directory, so I can call it from there.

    Hang on a minute and I'll fire up a vm and get you the file and path.


    Edit:

    Here you go.

    Depending on your VBox version number, you will need to use something like this in the terminal IN THE VIRTUAL MACHINE, of course:

    Code:
    sudo /media/VBOXADDITIONS_4.1.8_75467/VBoxLinuxAdditions.run
    That may not be your version number, so check what you have and make changes accordingly.

    (My apologies, by the way. I did something I try not to do: assume that you understand exactly what seems obvious to me. I should have done a better job of explaining it in the first place.)

    If you would, please mark this thread as solved so that the next guy with a similar issue will know there is a solution.

    And you are certainly welcome! I accept payment in unmarked bills in small denominations...

    This is a really stupid question, I'm trying to mark it as solved, but how do you do it?

    Not a stupid question, just stupid instructions again. Doh!

    In the upper right portion of the screen, look for "Thread Tools". In the drop-down box, make the selection to mark as solved.

    Getting late. I'm getting even more stupid than I can account for because of my age.

    Re: Virtual Box full screen problem

    Hello All,
    I was using Ubuntu 11.10 in VirtualBox.
    One day it automatically prompted me to upgrade to
    Ubuntu 12 and to a new version of VB.
    It works fine and all is well; except now, I cannot
    get full screen!
    I followed the steps above, but alas, it didn't work.
    I changed certain numbers to reflect my version of VBox.

    Does anyone have any idea? I refuse to use Ubuntu now since
    it is so tiny. I miss using it. Any tips?
