Virtualbox ubuntu full screen commands how to#

At the end of this blog post I give some tips on how to make an export of a VM small. This makes uploading and copying the VM much easier.

If you have created a nice VM and want to distribute it, it helps if the VM export is not too large. Do think before you execute these (or similar) steps since if you do not do them correctly, you might screw up your partitions and potentially lose data. If your partition layout differs, the steps to take are similar but might differ slightly. I’ve done a pretty default Ubuntu 16.04 installation as guest in VirtualBox. In this blog I describe the steps I’ve done to increase the size a VirtualBox Ubuntu guest disk without loosing data.

For example if want to install additional software. After using the VM for a while, it happens (often) that I need more space than I initially assigned. I think it will be enough for what I want to use the VM for. I believe that this is a safety measure, to ensure that the OS will work with all kinds of displays.Sometimes I create a VirtualBox disk for usage in a VM with a certain size.

Before you install the proper drivers, the screen resolution is low, and everything is pixelated (if there is such a term). You might have experienced something similar if you ever tried adding a graphics card to your system.

They consist of device drivers and system applications that optimize the guest operating system for better performance and usability.

It appears that the Guest Additions are analogous to installing driver software. You can use the full resolution of your Host display by entering fullscreen ( Host + F) after rebooting the Guest system.

Confirm and provide your password (the root password) and you are done. Ubuntu will ask you if you want to allow the CD to automatically run a program. To do this, click the Devices menu > Insert Guest Additions CD Image. Installing the VirtualBox Guest additions auto-magically solved my problem. I tried changing the guest resolution with GUI, but a higher resolution was not listed. Unfortunately, xrandr failed to work for me. NOTE: I have VirtualBox 4.3.10 and Ubuntu 14.04 amd64 and guest additions don't work properly on it for me too, so I assume I will have to wait for next VBox version. Without the successful installation of guest additions, VirtualBox does not re-adjust guest resolution automatically, so graphics inside VM may look grainy/broken on bigger screen. Was the installation of guest additions successful? You can check this by going to View menu and see if 'Auto-resize guest display' is enabled. Pressing right Ctrl + F will toggle full screen of that monitor. wait for it to do it's business and then restart the Guest OSĪfter you run this, VirtualBox should automatically resize the Guest resolution to the window size.run the n script within the newly mounted cd.Mount the Guest Additions by selecting Devices -> Insert Guest Additions CD image.

In order to enable the native resolution of your monitor you'll need to properly install the Guest Additons. When using VirtualBox the default resolutions are limited to just a few common resolutions. Once you set the resolution in the VM, VirtualBox will automatically resize its window on the host.īy the way, here's the official Ubuntu documentation about changing the screen's resolution. Now run xrandr -output -size and replace 'output' and 'size' with the connected output that you got from the previous command (in this case VGA1) and the resolution you want to set, I recommend setting it just a bit lower than your actual monitor to leave space for the taskbar and Virtualbox window title bar.Įxample : xrandr -output VGA1 -size 1920x1040. VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm If you manually resize the window on the host you'll only zoom on the image returned by the VM, so of course this gives a very bad image quality.Ĭhange the screen's resolution in the VM's configuration, either via the GUI, or directly via the command line with xrandr.įirst run xrandr with no arguments, it'll display all outputs (in this case they're just the virtual outputs emulated by VirtualBox). The window size is controlled by the VM's screen resolution.
