I have added this image on VirtualBox 4.1.8 (host Windows 7) and all it’s OK.
Then, when in Ubuntu there are software updates, I install them and the screen resolution became 800×600 (the right one should be 1366×768); so I install the Guest Additions and, at the reboot, the screen resolution is right, but the destop is empty and neither toolbars on the top and on the left appear (http://i39.tinypic.com/33aqbf4.png).
Why? What should I do to solve this problem? Thanks.
@alessandro
I think that you can modify the video RAM amount to 64:128 RAM, remove guest additions, reboot and reintall them.
Please test if login to gnome classic (gnome-fallback) solve the problem, unity is is a mystery.
Thanks! The code at the end of your message was the right one, although some files or directories was not found when I type some commands, but when I have rebooted the system, now it works!
P.S.: Why are we speaking in English if we are both Italian? 😀

Hi, here there are people from all the world, all the comments are preferable in english, sorry.
If you want can write me by mail for private questions, in italian of course 😉
My english are bad, I think.
ciao.
A.
Don’t worry, I was joking. 😉
Anyway, now I have installed again new updates and the problem was again here, but, after I have executed the command lines you suggested me, it’s all OK now.
So I have to do this every time I install some update…
Just two naive question:
1. What’s the root password? toor doesn’t work…
2. Keyboard mapping is for Italians? It all mess up when I type special characters such as / or – in my standard keyboard.
I have added the user ubuntu (who is an administrator user) to the group vboxsf with the command: sudo adduser ubuntu vboxsf
but I can’t access to that folder anyway…
@ale83_webmaster
in practice add your user to ‘vboxsf’ group in the guest machine, after set your folder as “automatic mount”, restart the service vboxadd-service and logon again or use ‘sudo’ to list the folder /media/sf_xxxxx (root/vboxsf, 0770 permissions)
sudo adduser $USER vboxsf sudo service vboxadd-service restart
The answer to this command is vboxadd-service: unrecognized service
Anyway, after a reboot, now I can open that folder, but it’s empty.
Then, I have tried to put a file into it, but going in the shared folder in the host OS I see only the files I have added from that OS.
A question.
Why in the list of the installed languages is there also Chinese, even if it isn’t really installed? Is it possible to remove it definitely and how?
Thanks!

I have tried to set the video RAM to 128 MB but nothing changes.
How can I do to remove Guest Additions?
To remove GA, mount the ISO of GuestAdditions, move to correct path and execute:
sh ./VBoxLinuxAdditions.run uninstall
alternatively read this topic:
https://forums.virtualbox.org/viewtopic.php?t=7839
This code seems to work:
sudo find /etc -name "*vboxadd*" -exec rm {} \;
sudo find /etc -name "*vboxvfs*" -exec rm {} \;
sudo rm -r /usr/src/vboxadd-*
sudo rm -r /usr/src/vboxvfs-*
sudo rm /usr/sbin/vboxadd-timesync
sudo rm /lib/modules/`uname -r`/misc/vboxadd.ko
sudo rm /lib/modules/`uname -r`/misc/vboxvfs.ko
Bye,
A.

What is the Password? I can’t login at all..?
If you read the article, it was already written…
Read here: https://virtualboxes.org/images/ubuntu/
Username and password are ubuntu / reverse
@Merlin Ran
Hi,
root have a scrambled password as all ubuntu installations.
If you you want assign one to root, use the ‘sudo’ feature:
sudo passwd root
For the keyboard question, instead, reconfigure console-setup
sudo dpkg-reconfigure console-setup
Enjoy,
Antonio
Where can I find the shared folder that I set in VirtualBox into Ubuntu?
I have found a “sf_Shared_folder” in /media but it says I don’t have sufficient permissions to view its contents…
@ale83_webmaster
Look here:
http://www.virtualbox.org/manual/ch04.html#sf_mount_auto
“Access to auto-mounted shared folders is only granted to the user group vboxsf…….”
bye,
Antonio

Hi,
only english pack is installed.
As reported here:
http://askubuntu.com/questions/101282/language-support-has-an-unwanted-chinese-language-option you can remove the locale with the command:
sudo locale-gen --purge
I test it on the original image, see these:

Enioy,
A.
