Today I’ve upgraded my kernel to 2.6.27-11-generic, and some fixes were necessary to get my Ubuntu to work again.
I tried to open VirtualBox but I get this error:
Executing the command that they suggest worked like a sharm:
sudo /etc/init.d/vboxdrv setup
The other problem was due to wireless. Again I needed to recompile the madwifi so I could get it to work for the new kernel. I’ve Followed the post Re: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01) and it’s working again!
