How to uninstall Guest Additions in Ubuntu guest?

[riobard]

I installed Guest Additions in Ubuntu guest. Now I copied the Ubuntu guest to a real harddisk and used it on a separate machine, so I no longer need the Guest Additions. How do I uninstall it? Thanks in advance!

Dont really know it exact.

Little Tip: Start the installer with "--help". That shows possible Parameters.

I tried --help option but it does not say anything about uninstallation

here is what I got:
-------------------------------------------------
Makeself version 2.1.4

./VBoxLinuxAdditions.run --help Print this message

All I know is that after a kernel upgrade you need to reinstall the GA if you want to have most things working again, like shared folders. That takes my assumption that it only installs a few kernel modules. A 'find' or 'locate' should give you some idea of where any virtualbox files might be and you can then remove them. Do not forget to modify your xorg.conf file if you haven't done so already for your mouse and video driver (video has to be, else you wouldn't have X).

I guess it is much more complicated than just deleting kernel modules. I even found a /dev/vboxadd any hints about this? Thanks!

You are correct in that their isn't a proper remove utility but the vbox device drivers and the ubuntu forum give simple instructions on how to remove them.

You also need to remove the /etc/rc1.d/ entries. After the reboot, I think that you'll find all vbox entries are related to VirtualBox and can be removed

[riobard]

I tried the following lines and it turned out to be OK now. Thanks guys for your help!

Code: Select all   Expand viewCollapse view

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


A little explanation:
1. All vboxadd* entries belongs to Guest Additions
2. All vboxvfs* entries are related to Shared Folder feature which is also part of Guest Additions

Besides the unistall

/opt/[VboxAddonsFolder]/uninstall.sh

I also had to remove /etc/X11/xorg.conf

Doing both the uninstall.sh and removing the xorg.conf file :

This solution Worked for me!

On an Ubuntu host that is not a VM, do:

aptitude purge virtualbox-guest-utils virtualbox-guest-x11

That stopped the messages for me.

Folks,
Thank you, thank you, thank you. This line , aptitude purge virtualbox-guest-utils virtualbox-guest-x11, removed the startup texts that plagued me each time I logged in. However, I have no idea what I did when I entered the line in the terminal.
Being slow I need an entry level step by step how to before I can get this kind of good stuff stuck in my gray matter. So I want to thank the person who added the post. Should I need help in the future I will heed this users posts.
God bless you.
