Virtualbox to 4.2.12 problems with Ubuntu

After updating Virtualbox to 4.2.12 and updating the guest additions on my Ubuntu 12.10 the guest suddenly started having problems with the graphics driver ( wouldn’t start correctly, only starts in “rescue” mode). I did a bit of googling, and it seems other users are also affected (mainly 12.04 and 12.10 Ubuntu), and it seems to affect people who upgraded from virtualbox guest addditions 4.2.10 -> 4.2.12

Here the quick and dirty workaround to the problem: download the 4.2.10 guest additions and use them.

Will need to reboot or make sure the new modules are loaded and restart X afterwards.
