Ok, it seems there’s a bug in ubuntu 9.10 (and maybe earlier) with the apple macbook keyboard. The goal should be to map the right command (apple) key as ALT-GR.
A simple workaround is getting to System->Preferences->Keyboard. Select the Layout tab and layout options. Then select the key to choose 3rd level and enter on keypad. Now you can use the enter key (just beside the right apple key) as ALT-GR.
If you are in hurry you can skip this section. 🙂
I had an old laptop with no capabilities of booting via USB and with a broken cd-rom, but a working floppy. So the main goal was to boot the computer from a floppy then tell the computer to boot via the ubuntu live installed on an USB key.
What you need.
- A computer that can boot from cd and a USB port.
- A computer with a running floppy drive.
- An empty USB key (>=1Gb).
- An empty Floppy (1.44Mb).
Create the bootable USB
Boot the pc with the desktop live cd-rom. Plug-in the empty usb key and make it bootable. From Applications menu there’s a voice like create USB key. Otherwise you can have a look at the Installation from USB stick on ubuntu official site.
Create the bootable floppy
I’ve tried many way to have a bootable floppy, that can recognize the USB key for booting (dsl, sbm, …) but the only one that had worked was: plop bootmanager. As advised me on the TiLUG Mailing List (Italian).
Download the latest version of plop boot manager (at the time of writing: 5.0.5), expand the obtained zip wherever you like and write the image on the floppy: dd if=plpbt.img of=/dev/fd0.
Now insert floppy, plug the usb key into the computer with broken cd-rom and boot it via floppy. When asked, select USB from the menu and that’s all folks!
