Unable to make the ubuntu screen to full screen in virtual box

Post by user18 »

First, I installed the virtual box and then installed Ubuntu on it and added the guest additions CD image and run it...
It worked and my ubuntu got full screen size...

The next day when I opened ubuntu on my virtual box.. It's not displaying in full screen mode eventhough I choose View > Full-screen mode

So I decided to run the autorun file and I run it...I've attached an image which shows the problem

Can anyone help me with this issue...!

The message says it's trying to run an uninstall of the Guest Additions, and the uninstaller script cannot be found.

Let's see if the GAs got installed correctly:

Please start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show in Explorer/Finder/File Manager. In the "Logs" subfolder, zip the VM's "vbox.log", and post the zip file, using the forum's Attachments tab. (Configure your host OS to show all extensions so you can find the "vbox.log", not "vbox.log.1", etc.)
