How to Change Screen Resolution in Virtualbox
Embed
- Published on Jun 26, 2010
- The easy way to install the guest additions necessary to alter Virtualbox's default resolution.
Commands needed after Guest Additions ISO has been downloaded, mounted and the appropriate file copied to desktop.
cd /home/usr/Desktop
chmod +x VBoxLinuxAdditions-amd64.run
chmod +x VBoxLinuxAdditions-x86.run
sudo ./VBoxLinuxAdditions-amd64.run
sudo ./VBoxLinuxAdditions-x86.run

All I had to do was change the settings of the guest OS. In my Lubuntu guest, it was Preferences > LXQT Settings > Monitor Settings. Then I could use scaled mode to make it fill my host screen. It took me so much time to figure this out. I had been severely limited by the default res, since applications used larger window sizes than the screen res. This video really didn't help.
You don't say what the command is to change the resolution or provide it in the description
Works like charm.
For Windows 10 hosts, no need to execute the last command. Just restart the VM.
The last command was not recognized for me, I went desperate until I realized my resolution is fixed already lmao.
Thanks for this. Got me sorted nice and quick
Whenever I run this on my Windows 10 is destroys my whole machine and I need to restore from a snapshot. Amazing.
Ouss Rip
Destroyed my shit too.. And I Didn't have a snapshot :(
Thanks man. Really work for me
holy hell dude, fix your mic
thank you so much for the help!!
Doesn't work. Still only 1024x768. Other virtual machines work fine
Thanks
Thank you very helpful!
It works very good, thanks :-)
btw, google suggested your videos when I searched in google for how to do it. Good job on those tags
Just go to setting and look for display and change the scale. It will change the guest. No need to go thru this elaborate procedure
Your voice is raping my ears and make my eyes water. Jesus I can't bare it!
When i try to do the sudo ./VBox... it is saying "cannot execute binary file" on Mac Sierra. Any reason why this doesn't work?
you dont copy de dot exe file instead of the dot run file
It work !!!! Thanks.
thank you so much for helping me out
What desktop environment are you using?
linux mint default, probably custom, or gnome
Thank you!!!!
THANK YOU SOOO MUCHHH!!!!!
thx!
Thank you
GG WP
Thank you! This solved the problem!
THX
What if i want to expand the screen into 2 monitors?
you have option in virtual box for it...
I looked for hours on how to change the resolution. This was the only one that worked. Thank you!
very helpful... thank you
Hey thanks a lot, it worked! Liked!
What about on Windows 3.1 and Windows Chicago Build 189?
Thank you dude!
It worked with XP without doing nothing (not any Terminal Command, just installing the thing that opens with autorun after the adding the CD)
Thanks again...
NOT always work!
Thanks a lot for this video! Really helpful, works without a hitch!
For those who are using Windows 8/8.1 as host machine, there is no need to enter that last command anywhere. Just shutdown your guest OS machine and start it up again... it automatically switches to a proper resolution!
@Ek Bhartiya not happy to see boys trying to hook up in youtube comments
happy to see girls are intrested in linux too
what to do if host os is windows 8? no idea what i'm doing.
use cmd just pres windows+r and type cmd
My host is Windows 10 and I got the guest additions CD installed, but I can't seem to make anything work in MS-DOS. Do I still need to do that part or does copying the file to the desktop finish it up?
+cornholio223 You just do the first part of this tutorial. No need to back to host OS and type the rest. I am using a win10, it works on mine. When you restarted, ubuntu will go full screen
+cornholio22 I am having the same problem, but my host os is Windows 10
After installing Guest Additions and quitting VirtualBox, the command to enter into the host computer's terminal is:
VBoxManage setextradata global GUI/MaxGuestResolution 1272,920
or some other resolution instead of 1272,920
Go to the folder of virtualbox Ej: C:\ProgramFiles\Oracle\VirtualBox
help im running kali and get "bash: VBoxManage : command not found"
+Philip Ganchev I made it all the way until the last command line (which you have posed in the comment I'm replying to), but when I enter it I receive the error " 'VBoxManage' is not recognized as an internal or external command, operable program or batch file'". My host computer is running on Windows7. Can you offer any solutions to this?
@Philip Ganchev cheers!
Thanks, this made my life easier !
This video is still relevant!
works for me.
Thanks it worked for me ... In Ubuntu
What is the url for the terminal? I cannot use the hotkey ctrl+alt+t, also it doesn't appear when im searching for it in the Computer map. I can also not navigate through a menu, which I would blame the low resolution.
just right click or double click for mac users and then you change the screen resolution according to your will. Simple and fast!
right click what??
i just did install guest editions, asked me where to save it on the virtual machine, and let it "install" (like a standard install.) lots of thx for this ^^
When I try to do this, it simply gives me .exe files no .run file. What am I doing wrong?
wow way easier now!
OSX -> For those that are experiencing "Insert Guest Additions CD/DVD" (and nothing happens). You can locate the Guest Additions ISO from here -> Right click on the VirtualBox icon in OSX Finder and choose Show Package Contents. There it is located in the Contents/MacOS folder. Your looking for the VBGuestAdditions.ISO' - Copy it to your VB machine (desktop for ease), then mount it, run it. This will fix the restraint resolution issues.
Thanks!
I used virtual box setup a windows 7 vm on my linux computer and actually after I clicked on mount, it took me through a wizard. After the wizard was done all I had to do was hit the resize button and I was done.
Thanks for info, but why it has to be so complicated? Is like linux stay in the 80s, like when we use MS-DOS. Make a simple mouse-click way. I suppose is not the fault of the person that make the video. Maybe is the only way. In that case I blame linux developers. They think everybody must type commands to do stuffs.
@Andrés Schwartz nevertheless, linux is only for geeks. Nothing wrong about that, but that exclude the majority of users to use linux.
By the way, installing a program or plugin don't seem as advanced task to be force use commands
Eso es porque hacer aplicaciones visuales sale 'caro'. Y como esto es voluntario, no a todos les gusta hacerlas.
Igualmente empresas como Canonical sí lo hacen.
Pero para un usuario desarrollador de linux es muy fácil, cómodo y rápido usar comandos. Es como hablar con alguien diciéndole qué hacer, en cambio hacer clics es lento y limitado, si lo anterior es como decirle a alguien qué hacer, esto último sería como hacerlo tu mismo (obviamente hay menos ganas jaja, mejor que lo haga otro). Depende el caso, pero muchas cosas se pueden hacer con comandos flexiblemente pero pocas se pueden hacer visualmente con clics, excepto si es para diseño, videojuegos, mover elementos gráficos, representación o simulación gráfica, pero para configurar y programar es más práctico y cómodo escribir con un teclado órdenes.
When I go to DEVICES > drop down menu I do not have the option to "Install Guest Additions"
The only option I have at the bottom is to "Insert Guest Additions CD Image…"
Did I install it wrong or something? Im running Mac OSX and the Guest VM is Windows Vista. This entire process has just been frustrating beyond belief!
The magic command typed at the host O/S at 2:21 was
VBoxManage setextradata global GUI/MaxGuestResolution 1272,920
It looks like it is even simpler now. The installer autoran when I mounted the ISO.
When I followed the instructions to chmod and run the installer it just uninistalled and reinstalled itself.
Thanks - very useful.
It did not occur to you to put that universal command in the description of this video as well...
thanks buddy it works for mee.........:)
It cant because it does not come with your os.
Thank you for this video excellent work! Really saved my bacon.
I had this error on Lubunt:
Unable to mount the CD/DVD image /usr/share/virtualbox/VBoxGuestAdditions.iso and
Could not mount the media/drive /usr/share/virtualbox/VBoxGuestAdditions.iso
(VERR_PDM_MEDIA-LOCKED)
It asked if I wanted to force mount, but the only buttons available were 'Force Unmount' and 'Cancel'.
The solution to this was to do
sudo apt-get install virtualbox-guest-x11
After that I rebooted my machine.
I'm running Windows 7 Home Premium as Host, and Fedora 18 as my Guest. I am able to install Guest additions, but nothing happens at all, whereas, when i installed Windows 8 beta, and did the same thing, it installed, and I restarted with 1920x1080 without having to make any changes.
then I restarted and I have it back at the smaller resolution, with guest additions still installed : /
Thank you very much. I can't install guest additions using devices menu. I succeeded!. I'm so happy
That helped. Thanks.
Say aye. AYE.
im running windows 8 inside windows 7, and am having the same problem :/
I'm running a Windows7 OS inside my Windows 8 host OS.
After clicking "install guest additions" from "devices" on the VirtualBox toolbar menu, no dialogue box appears. Assistance anyone?
Chmod, seriously? Just run it as root.
Simple and perfect. Thank you.
Hi, mine does not ask me to download and install an image.
Mine says something about do you want to dismount an image
man this is crap, i cant understand why the hell oracle dont supply all that stuff in the install.
could someone either make or direct me to a video that shows how to install the guest additions when you have Mac OS X in virtualbox lol i cant seem to find one yet so im not sure if one has been made
Goddamn guest additions, should come preinstalled.
Soooooo... if you go into the virtualbox.xml with a text editor, I used notepad++ and REMOVE the line that spesifies max resolution, turns out it will dynamically adjust to whatever window size you set it to. What moron at Oracle set this as a default? You shouldn't have to go in and remove code to magically make it better.
Thanks for the help breaking it. "The value '800,600?' of the key 'GUI/MaxGuestResolution' doesn't match the regexp constraint '\d*[1-9]\d*,\d*[1-9]\d*|any|auto'."
The command needed to be entered in host os is not in the description but we need it badly! Please send us the command that we must enter into the host's os terminal so that we may change our screen resolution! REPLY ASAP !
thanks for tutorial......its very useful
You linuxdistroreview = Hero =)
what is the command line to change the resolution, its not in the description :(
Thankyou! :)
