Higher screen resolution in VirtualBox?












143















I've just installed Ubuntu 10.04 into VirtualBox on Windows 7.



Unfortunately the only options showing for screen resolution are 640x480 and 800x600 and the monitor is showing as 'Unknown'.



How would I go about upping the resolution to 1280x1024 (I'm on a 1600x1200 monitor)?



Update

I tried mounting the VirtualBox 'Guest Additions' ISO (from the VBox 'Devices' menu) and doing sudo sh ./VBoxLinuxAdditions-x86.run
from the mounted drive, which gave 2 new listed resolutions after a reboot (1024x768 and the 16:9 version of that resolution). These worked when I selected them but disappeared when I switched back to another resolution. I tried rebooting and running VBoxLinuxAdditions-x86.run again but onlu the 2 low res options listed this time.

I think I'm going to reinstall...



Seems to be a VBox problem rather than an Ubuntu problem as after reinstalling 10.4 overwriting the original virtual partition, sudo sh ./VBoxLinuxAdditions-x86.run now has no affect at all.

  • If you do not use X with VBox (like me), you can use Putty to SSH. The Putty window can be sized.

You need to install the VBox guest utilities to add support for the virtualised graphics hardware.



sudo apt-get install virtualbox-guest-utils virtualbox-guest-x11 virtualbox-guest-dkms


Previously you might have needed the "ose" versions:



sudo apt-get install virtualbox-ose-guest-utils virtualbox-ose-guest-x11 virtualbox-ose-guest-dkms

    I think the ose tools are only useful if you're running the OSE edition of Virtualbox.. For the closed source version you should use the most recent ones that can be installed as the OP indicated.

    @MattiPastell I think your comment is outdated, as Oracle has merged the OSE and non-OSE versions of Virtualbox; as of version 4.0, the non-OSE components are added separately with an extension pack. See the VirtualBox website for more info

  1. Start Virtual box and log into Ubuntu.


  2. Hit the right ctrl key so you can get your mouse pointer outside the virtual machine.



3.Go to top of virtual window, click on devices then select "Install Guest Additions"
You will see a window pop up inside Ubuntu showing you that there are some new files mounted in a virtual CDROM drive. One of those files should be VBoxLinuxAdditions.run



You must run the file with some admin permissions so do that this way...




  1. Click inside the Ubuntu screen again then go to Applications - Accessories then Terminal. The terminal window is where you will run the file from, but first we must navigate to the correct directory.


  2. type this... cd /media/cdrom0 (then hit enter, there is a space after cd!)


  3. next type... dir (You should see amongst the files displayed VBoxLinuxAdditions.run)


  4. now type... sudo sh ./VBoxLinuxAdditions.run (yes, that is a full stop before the slash!)



after you hit enter and it has done its stuff, the files are now accessable from Ubuntu.




  1. You now need to reboot the virtual machine or press Ctrl+Alt+backspace.


  2. Log onto the Ubuntu desktop and this time go to System - Preferences then Screen Resolution. You should now have more options than the three low res options you had at the beginning of the day!



if the resolution you want is not one of the newly listed ones then follow these steps...




  1. Open the terminal window again (Applications - Accessories then Terminal)


  2. Type... sudo gedit /etc/X11/xorg.conf (space after gedit and X11 must be capital X)


  3. It will ask you for a password which is the same as you log in with.


  4. The text editor loads and you should see a lot of text in the window. First make a backup of this file by going to "file" then "save as" and changing the filename to xorgbak.conf


  5. You now need to hunt through the text until you see the display resolutions listed. The ones you will be concerned about will be listed under bit depth 24 or bit depth 16 (as these depths are the ones that give you a large amount of colors.)


  6. The idea here is to have your favorite screen resolution included in this list. Do this by either inserting it before the other listed resolutions in the exact same manner or typing it over one of the others. (you will only need to do this for the ones under bit depth 24 and 16)


  7. You must now do a "save as" but be careful here as this time we need to call the file xorg.conf again. If you just hit save here you would have saved the changes over the backup file you created!


  8. You are done. Hit Ctrl+Alt+Backspace to restart your virtual box, log in and enjoy your new screen resolution options!

    There is NO operation "Install Guest Additions" in devices. You mean "Insert Guest Additions CD" I think. You have to choose the iso by rightclick on the cd image in the right bottom corner, find BY HAND the iso in the virtualBox folder and turn it on.

Devices > Install Guest Additions, let it run then log out.



When you've been returned to the login screen you'll see it's the full size of your monitor. Log in and you're good to go.

Once the Vbox Additions has been instaled (and reboot the guest os), press Host + H, then maximise the window, thats sould do the trick..

If not, maybe you are using an old version of vbox (therefore, the Vbox Additions might has an incompatibility..)

    At least in the latest version of Virtual Box (4.2.16), it is [Host] + [F]. In my case, I just need to press this two times (activating & deactivating) for having Ubuntu displayed in the maximum resolution.

Try increasing the amount of RAM allocated to the Virtual Box. Worked for me.



To do this, stop the VM, then in VirtualBox go to the Settings for the VM. Go to the Display section. You can increase the Video Memory there. Mine was 1MB; I increased it to 32MB and that allowed me to use my 24" monitor fully.

  • Settings > Video > Video Memory = 128 MB, Enable 3D acceleration = true.

  • Install GuestAdditions


  • On Host machine, in cmd/bash, run



    VBoxManage setextradata global GUI/MaxGuestResolution any



  • create /etc/X11/xorg.conf file with content:



    Section "Device"
    Identifier "Configured Video Device"
    EndSection
    Section "Monitor"
    Identifier "Configured Monitor"

  • For running VM:



    Host Key Right Ctrl at default + Home = view full screen.




I have tried to exclude every step except GuestAdditions installation. You need every one of them.

I can tell you how I do this with Mac OS X as the host system. Maybe it will work on Windows too.




  • I start ubuntu in VirtualBox

  • I open up the terminal on Mac OS X

  • and execute "VBoxManage controlvm [name] setvideomodehint 1280 1024 24" (replace [name] with the name of your ubuntu vm)

            It is probable that your brand new install of a linux distro on your Virtualbox is still fresh and that much more needs to be done to set up your environment, not the least of which is to enable the X Window system if all that you are seeing are display settings for 4:3 aspect ratio and entering 'startx' at the command prompt does nothing.



            ..at your terminal prompt, enter the following:



            sudo apt-get install dkms
            sudo apt-get update
            sudo apt-get install linux-headers-`uname -r`
            sudo apt-get install --reinstall xorg
            startx


            If you had set your virtual machine to fullscreen mode prior to entering 'startx', then the screen will automatically adjust to 16:9 aspect ratio, with tool and task bars in their proper places.

              Apart from installing the Guest Additions plugin, note that the maximun display size may be capped in VirtualBox general preferences panel:



              enter image description here



              Also, check autoResize option and VirtualBox will automatically set the display size as you resize or maximize the window.

              • Setting the maximum to "Hint" and then chosing reasonable values for width and height made the desktop open up in that size after a reboot. (Make sure the video memory is not too small).

                VirtualBox 4.3.12 was preventing the above solutions from working on my Windows system.
                4.3.18 was released somewhen around 2014/10/10 (2014 Oct 10), all of the above works since installing that.



                The "VBoxManage setextradata global GUI/MaxGuestResolution any" command appeared to work previously, that is to say it didn't throw any errors.



                Installing guest additions had previously complained that the header files were not installed, however they absolutely WERE (& have been left untouched) as evidenced by the fact that installing guest additions under 4.3.18 upgrade does not throw the error when building the shared folders module.

                  Here is a 2016 updated answer that worked for me.



                  To start, I'm on Mac 10.11 (El Capitan), and my VirtualBox is 5.0.26. I'm running Ubuntu 14.04 LTS in this example (I need to upgrade my Ubuntu eventually).




                  1. Start your VM

                  2. Select "Devices -> Insert Guest Additions CD image..." (no, you don't actually need a CD, this is virtual)

                  3. This will open a window asking for your root password

                  4. A terminal window will open. If it asks about re-installing over a previous version of guest additions, type "yes" and hit return

                  5. Restart your VM

                  6. Once the VM is up and running again, go to "View -> Virtual Screen 1 -> [whichever resolution you want]".


                  My options were all the way from 640x480 to 1920x1200. Once I selected a new resolution, I did not have to restart the VM again, it automatically scaled.

                    If none of the answers helps you fixing the issue (like it was situation with me), then verify on your Host OS that in "Screen resolution" window (Control Panel > Appearance and Personalization > Display) whether the displays are aligned and not like in picture from the following link:



                    Preview of settings on Host OS that caused me issue with maximum resolution on Guest OS



                    If someone is confused because of the value of shown Display field, the reason is that I don't use Windows 7 as my Host OS, so I've used it on VirtualBox in order to simulate problem.



                    If you would like to use different resolution on each monitor and/or you are not sure how to align displays in previous window, clicking on "Detect" button should do things properly for you.
                    You probably wouldn't suspect that that causes problem because, if you use Windows 7 (or any newer versions of Windows) as Host OS, it will successfully render image on your monitors, even when the set positioning is distorted as shown.



                    I've been struggling with this problem on many tested Guest OSs like Ubuntu, Windows XP and Windows 7 (so the issue in my case wasn't related to Ubuntu nor Linux at all) and after properly configuring that setting, I was able to choose larger desired resolution in my Guest OS (of course, you should previously install VBox Guest Additions as it is stated in several answers).

                        My problem/solution was actually strange, I had a another laptop/monitor with a lower resolution set up in Windows as a main display. Therefore no matter what, even if I had a max option in View/Virtual Screen 1920x1200, this time it was not checked. I am using i3 GUI , gnome behaved even more strangely. Once I configured my 4k 3840x2160 in Windows as a main monitor, VirtualBox adapted correctly.
                        (Maybe I combine it with a lot of solution here at stackexchange and other websites.) ,but setting up the 4k display as a main display in Windows was basically a solution for me.



                        Note: Also previously I configured linux ubuntu resolution via command line by a process of these commands - How to set a custom resolution?



                        otherwise a one-liner resolution appliance command line and few easy steps



                        eval $(cvt 2220 1250 60 |sed 's/Modeline/xrandr --newmode /g'|sed -n '1!p')
                        what this one liner does:
                        (1st/3 part generates dimensions, 2nd/3part uses output and replaces with xrand to create logical display, 3/3part it has on the first line comment so it starts at 2nd line)



                        as a proper result resolution might be afterwards reevaluated and adjusted, therefore find out the created resolution by xrand command appended in the end of output,



                        1) assign the resolution to a specific display -



                        xrandr --addmode VGA-1 "2224x1250_60.00"



                        2) output the desired resolution on the display



                        xrandr --output VGA-1 --mode "2224x1250_60.00"

                          You need to install the VBox guest utilities to add support for the virtualised graphics hardware.



                          sudo apt-get install virtualbox-guest-utils virtualbox-guest-x11 virtualbox-guest-dkms


                          Previously you might have needed the "ose" versions:



                          sudo apt-get install virtualbox-ose-guest-utils virtualbox-ose-guest-x11 virtualbox-ose-guest-dkms

                            I think the ose tools are only useful if you're running the OSE edition of Virtualbox.. For the closed source version you should use the most recent ones that can be installed as the OP indicated.

                            @MattiPastell I think your comment is outdated, as Oracle has merged the OSE and non-OSE versions of Virtualbox; as of version 4.0, the non-OSE components are added separately with an extension pack. See the VirtualBox website for more info

                          I think the ose tools are only useful if you're running the OSE edition of Virtualbox.. For the closed source version you should use the most recent ones that can be installed as the OP indicated.

                          @MattiPastell I think your comment is outdated, as Oracle has merged the OSE and non-OSE versions of Virtualbox; as of version 4.0, the non-OSE components are added separately with an extension pack. See the VirtualBox website for more info

                          1. Start Virtual box and log into Ubuntu.


                          2. Hit the right ctrl key so you can get your mouse pointer outside the virtual machine.



                          3.Go to top of virtual window, click on devices then select "Install Guest Additions"
                          You will see a window pop up inside Ubuntu showing you that there are some new files mounted in a virtual CDROM drive. One of those files should be VBoxLinuxAdditions.run



                          You must run the file with some admin permissions so do that this way...




                          1. Click inside the Ubuntu screen again then go to Applications - Accessories then Terminal. The terminal window is where you will run the file from, but first we must navigate to the correct directory.


                          2. type this... cd /media/cdrom0 (then hit enter, there is a space after cd!)


                          3. next type... dir (You should see amongst the files displayed VBoxLinuxAdditions.run)


                          4. now type... sudo sh ./VBoxLinuxAdditions.run (yes, that is a full stop before the slash!)



                          after you hit enter and it has done its stuff, the files are now accessable from Ubuntu.




                          1. You now need to reboot the virtual machine or press Ctrl+Alt+backspace.


                          2. Log onto the Ubuntu desktop and this time go to System - Preferences then Screen Resolution. You should now have more options than the three low res options you had at the beginning of the day!



                          if the resolution you want is not one of the newly listed ones then follow these steps...




                          1. Open the terminal window again (Applications - Accessories then Terminal)


                          2. Type... sudo gedit /etc/X11/xorg.conf (space after gedit and X11 must be capital X)


                          3. It will ask you for a password which is the same as you log in with.


                          4. The text editor loads and you should see a lot of text in the window. First make a backup of this file by going to "file" then "save as" and changing the filename to xorgbak.conf


                          5. You now need to hunt through the text until you see the display resolutions listed. The ones you will be concerned about will be listed under bit depth 24 or bit depth 16 (as these depths are the ones that give you a large amount of colors.)


                          6. The idea here is to have your favorite screen resolution included in this list. Do this by either inserting it before the other listed resolutions in the exact same manner or typing it over one of the others. (you will only need to do this for the ones under bit depth 24 and 16)


                          7. You must now do a "save as" but be careful here as this time we need to call the file xorg.conf again. If you just hit save here you would have saved the changes over the backup file you created!


                          8. You are done. Hit Ctrl+Alt+Backspace to restart your virtual box, log in and enjoy your new screen resolution options!

                            There is NO operation "Install Guest Additions" in devices. You mean "Insert Guest Additions CD" I think. You have to choose the iso by rightclick on the cd image in the right bottom corner, find BY HAND the iso in the virtualBox folder and turn it on.

                            There is NO operation "Install Guest Additions" in devices. You mean "Insert Guest Additions CD" I think. You have to choose the iso by rightclick on the cd image in the right bottom corner, find BY HAND the iso in the virtualBox folder and turn it on.

                          If not, maybe you are using an old version of vbox (therefore, the Vbox Additions might has an incompatibility..)

                            At least in the latest version of Virtual Box (4.2.16), it is [Host] + [F]. In my case, I just need to press this two times (activating & deactivating) for having Ubuntu displayed in the maximum resolution.

                          Try increasing the amount of RAM allocated to the Virtual Box. Worked for me.



                          To do this, stop the VM, then in VirtualBox go to the Settings for the VM. Go to the Display section. You can increase the Video Memory there. Mine was 1MB; I increased it to 32MB and that allowed me to use my 24" monitor fully.

                                    I was able to fix this problem by shutting down my VirtualBox virtual machines, quitting VirtualBox, and running this command in a Terminal:



                                    VBoxManage setextradata global GUI/MaxGuestResolution any

                                                                  ..at your terminal prompt, enter the following:

                                                                                          1. Start your VM

                                                                                          2. Select "Devices -> Insert Guest Additions CD image..." (no, you don't actually need a CD, this is virtual)

                                                                                          3. This will open a window asking for your root password

                                                                                          4. A terminal window will open. If it asks about re-installing over a previous version of guest additions, type "yes" and hit return

                                                                                          5. Restart your VM

                                                                                          6. Once the VM is up and running again, go to "View -> Virtual Screen 1 -> [whichever resolution you want]".


                                                                                          My options were all the way from 640x480 to 1920x1200. Once I selected a new resolution, I did not have to restart the VM again, it automatically scaled.

                                                                                              My options were all the way from 640x480 to 1920x1200. Once I selected a new resolution, I did not have to restart the VM again, it automatically scaled.

                                                                                              To start, I'm on Mac 10.11 (El Capitan), and my VirtualBox is 5.0.26. I'm running Ubuntu 14.04 LTS in this example (I need to upgrade my Ubuntu eventually).




                                                                                              1. Start your VM

                                                                                              2. Select "Devices -> Insert Guest Additions CD image..." (no, you don't actually need a CD, this is virtual)

                                                                                              3. This will open a window asking for your root password

                                                                                              4. A terminal window will open. If it asks about re-installing over a previous version of guest additions, type "yes" and hit return

                                                                                              5. Restart your VM

                                                                                              6. Once the VM is up and running again, go to "View -> Virtual Screen 1 -> [whichever resolution you want]".


                                                                                              My options were all the way from 640x480 to 1920x1200. Once I selected a new resolution, I did not have to restart the VM again, it automatically scaled.

                                                                                                                      1) assign the resolution to a specific display -

                                                                                                                      xrandr --output VGA-1 --mode "2224x1250_60.00"
