Keyboard doesn't work on Macbook Santarosa

[drosophila]

Hi to everyone,

I've a macbook santarosa (13'' 2.4 GHz white) with Kubuntu Linux installed on as a single operating system. I've no refit installed.

In order to boot from usb and cdrom (this last one doesn't work) I tried to use plop with Grub 2. It works well (the boot works) but the keyboard doesn't work until the distribution on the USB card is entirely loaded (example: until the login prompt). I can't choose, for example, the several boot options from the Grub menu of the live USB distribution and looking for any errors in verbose mode.

How to fix it?

Thanks for the reply but isn't there a workaround? Because it is not useful if I can't choose the boot options

[Elmar]

a workaround is, you have to set the option that you use mostly as default option and use a timeout.

[drosophila]

and how to if the distribution is not my own or if it's closed source?

[Elmar]

the second and last workaround is to use a connected ps/2 keyboard

[drosophila]

then plop is not useful for laptop computers.. right?

I hope that in the next release you will fix this annoying problem

no, not right

I hope that in the next release you will fix this annoying problem

there is nothing to fix, its simply not implemented. 5.0.x will never support usb keyboards. why? it's posted in the forum somewhere.

Ok, before I start the searching for the reason, is there a method to customize plop in order to implement the my keyboard's driver?

no

[drosophila]

Ok,

thank you for the answers. If I'll found a notebook without implemented USB keyboards, I could use this boot manager.

[Elmar]

or you set the default boot with a timeout on the usb drive

I can't edit each distribution that I want to use.. I can't for several reasons:

1. I some cases, I don't know wich boot option I have to use
2. I can't edit the bootloader's configuration file if the distribution's source code is closed
3. It's not flexible operation (I would lose too much time)
