As soon as I updated to Natty my BURG stopped working. After a little tweaking here and there I somehow managed to get BURG install. So during the boot menu I do see the BURG menu but without the themes. Also none of the shortcuts to change resolution etc work. I have even tried using Burg Manager. Fail. Please help. This is urgent.
SourcesList.eu today have reported that there is now a Burg PPA.
Before I continue - Remember BURG changes your Boot Loader. Getting this wrong will stop Ubuntu from booting!
I've reproduced the relevant part of the article below to complete the answer:
sudo add-apt-repository ppa:n-muench/burg
Then if you want to install burg execute:
sudo apt-get update && sudo apt-get install
sudo apt-get install burg burg-common burg-emu burg-pc burg-themes burg-themes-common
Then (supposing that you wannt to install burg into MBR relative to hard disk named sda) execute:
sudo burg-install /dev/sda && sudo update-burg
Now you can use burg-manager to install new themes and to configure it.
