Love and Hate = Passion

OMG!

Today I planned to play with git, but as every time I plan something, something other ruins the whole day. It happened on an Ubuntu (8.10) guest (in Sun's VirtualBox 2.10), which is worked fine until now, but suddenly AltGr stoped working. There is no worse when you have to deal with such an annoying thing. I made some investigation about it, and try all the solutions, but nothing worked. Last, I reinstall it:(
By the way, if you are in the same situation, you should visit these sites:

Day 2:
Right now I noticed, all the trouble occured after installing guest additions in VirtualBox. Oh mom!
And that is what I expected:

The culprit was VBoxGuestAdditions version 2.10!!!. So, if you are in the same shoes, use VBoxGuestAdditions 2.06. Here is the solution:

# switch to super user mode
sudo -i
# install Dynamic Kernel Module Support
apt-get install dkms
# download the previous version of vbox guest addons
wget http://download.virtualbox.org/virtualbox/2.0.6/VBoxGuestAdditions_2.0.6.iso
# mount it
umount /media/cdrom
mount -o loop ./VBoxGuestAdditions_2.0.6.iso /media/cdrom
cd /media/cdrom
# install
# ideally it will reconfigure your current vbox driver set you installed before
./VBoxLinuxAdditions-x86.run

It worked for me:) I hope, Sun provides us a new fixed version in a short time. But I suggest you to take a snapshot sometimes in your VM.

Have a nice day!

Update:
Welcome again,

This morning a read my feeds and saw that a new VirtualBox version (2.1.2, bundled with a new VBoxGuestAdditions.iso) came to light:) [run and get it - http://www.virtualbox.org/] At that moment I downloaded and installed it. And of course setup the new VBoxLinuxAdditions-x86.run. Miracle happens:) Desktop integration works. Mouse integration works. AltGr works. Folder sharing works. SSH remote connection works. Thanks guys from Sun! Very great job!
