Ubuntu – VirtualBox resolution maxed at 1024×768 after Guest Additions

Ubuntuvirtualbox

So I've seen several posts say that installing Guest Additions for VirtualBox 4 running Ubuntu (host is Windows 7) should allow you to set a resolution higher than 800×600. There is also this answer on SuperUser, but the last comment says its deprecated for VB4.

I have installed guest additions, but the max resolution is still 1024×768. I want to up it to at least 1280×1024. I have set the display memory for the box at the max of 128.

Is this just as good as it gets, or am I missing something?

Make sure to turn off VM.

Then go to VitrualBox Manager > File > Preferences > Display > click Maximum Guest Screen tab and make sure to select either None or Auto (whichever works best).

Ubuntu – Make VirtualBox Guest additions fully functional again after upgrading to version 5.2.8

The bug report Unusable window system on Ubuntu 1204 guest using 5.2.8 or GA 5.2.7 says that the latest VirtualBox software causes all sort of problems when Guest Additions are installed.

It is counseled to go back to the earlier VirtualBox software that worked for you. In any case, do not use any version later than 5.2.6, at least until the linked bug is marked as fixed.

Ubuntu – VirtualBox, Ubuntu and screen resolution

After searching the other posts I found a solution that works:

In the Ubuntu VM, open a terminal and type:

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

With the VM running, use the Devices menu option which is available in the host operating system.
Select the option "Insert Guest Additions CD Image..."

Back in the Ubuntu VM, open a terminal and type:

cd /media/<username>/VBox_GAs_6.0.8
sudo ./VBoxLinuxAdditions.run

Once this has been done, shutdown and restart the VM.

Now everything is great!
