ubuntu screen resolution on 1920*1080

Make sure you have installed the VirtualBox Guest additions. Ubuntu is one of those distro's that doesn't install them automatically.

In the Package Manager look for "virtualbox-guest" and select all that is found for installation.

Default is 8MB video RAM in virtual machine - some 300KB short for full hd display.

I believe I did the Guest box additions.  I have the ability to change the monitor size. I don't have my aspect ratio though.  My monitor is 1920*1080.

I am not sure what you mean about package manager and "virtualbox-guest".

Sorry, what am I supposed to do with this?
"Default is 8MB video RAM in virtual machine - some 300KB short for full hd display."

Shut down guest and in video (or display?) section of vm settings slide video memory slider to 32MB or so.

The ubuntu package manager to get and install software, like synaptic. I always use synaptic, but the default one of ubuntu is called something else.

Once those additions are installed, you can pull your VBox window at the corners like any other window to resize it to the size you need. If your display's max resolution is 1920x1080 then you need to change your Ubuntu VM to use full-screen (right CTRL+F). You can't have full-screen in a window, as the window has normal windows controls and borders which make the actual desktop real-estate of the VM a little smaller.

I have it cranked to 128.

I did make some progress.  When I first started it only had something like 480*860 (or whatever the default is).

I was able to get bigger resolutions, but I can't get my aspect ratio.  This is a known issue.

People have mentioned things like this, but it didn't work for me.

Why dont you refer to OFFICIAL DOCUMENTATION OF VIRTUALBOX?
Your article deals with vmware. it has NOTHING TO DO AT ALL with VirtualBox (or Parallels, or HyperV or Virtuozzo or xen)

I have Ubuntu and Debian many versions VMs at proper 1920x1080, and I am pretty sure there was no problem to know for last couple of years...
Yes, it starts at 640x480, then it enters previosu video mode, once you log in it sets mode to full screen.

Anyone know of a solution?

Gheist, thanks for your help, but I would appreciate if you do not respond to this post again.  Thanks in advance for understanding.

As I already mentioned, use full-screen mode if your display is full-HD with a max resolution of 1920x1080. If you use windowed mode, you'll not get to the full resolution with any hypervisor or any guest OS.

If your display has a higher resolution than 1920x1080, then just resize it by pulling it's edges like when you resize any window.

That did not work.

This is a very common problem which can be seen if you google it. People have a lot of different suggestions on posts, and other people respond back how it did not work.  This is not a problem unique to me or something that I did not research.

You must be doing something wrong. I have just installed ubuntu as a VBox VM, rebooted, updated the OS, rebooted, then installed the VBox Guest additions, rebooted again. Then I set the VM to Fullscreen mode, and it displays perfectly with a resolution of 1920x1080 and the correct 16:9 aspect ratio. There was no problem at all.

What do you mean when you say "updated the OS"?
