Some issues while Checking Ubuntu Lucid 10.04 Alpha 3 in Virtualbox

I have been keeping up with the latest development builds of what will become Ubuntu 10.04 and all has been going reasonably well until the latest kernel install today. It appears that some of the code has been pack-ported from the latest upstream kernel - 2.6.33 - to the latest kernel in lucid - 2.6.32-16 - and it is causing an issue with Virtualbox.

After checking the forums, there is a kernel patch to fix this - see here

Basically, you need to edit this file -

/usr/src/vboxvideo-3.1.4/vboxvideo_drm.c

This code is installed with the Virtualbox tools that you must install before this file will be appear on the hard disk.

See the picture below:



Once you have edited this file and saved it , run the following command

sudo /etc/init.d/vboxadd setup

This will stop the problems with kernel crashes and the graphics not working correctly.

If you are also having problems with the mouse disappearing, then you need to turn off the visual affects in

Menu -> System -> Preferences -> Appearance

Set it to none, and the mouse will come back to life.

This is shaping up to be a great release, and once a few rough edges have been removed it will be an extremely useful addition to the ubuntu family.
