Description Ra P. 2007-02-07 21:55:51 UTC

if I run fedora core 7 test1 live cd x86 on a macbook core 2 duo, the keyboard
isn't usable until the kernel has booted, i.e. it doesn't work in grub. I've
tried ubuntu feisty (development) herd3 and this also happens.

Steps to reproduce:
1. press c on macbook startup.
2. boot from live cd
3. grub doesn't detect the keyboard and you can't change the kernel live
cd boots.

4. let the cd start, and once gdm has started the keyboard works.
5. reboot.
6. the keyboard works on grub

this bug has also been reported in ubuntu bug tracker:


Comment 1 Andrew Cathrow 2007-02-08 23:00:05 UTC
I wonder if this is related to the MacBook's BIOS(/EFI layer)
On the Core 2 Duo's it's easily reproducable.

This doesn't just happen on Live CD's it also happens with grub once the OS is
However this doesn't happen 100% of the time - I'd say that 3/4 of the time the
keyboard doesn't work in grub, I've not managed to work out the exact steps that
allow the keyboard to work.

Plugging in an external keyboard works but - you must plugin the USB keyboard
AFTER grub starts - not before.

This happens with and without rEFIt intall.ed

Moving to 'devel' as discussed on

Comment 3 Ra P. 2007-03-12 09:01:29 UTC
this also happens on fedora core 6. I thought reporting on the lastest
development snapshot was more correct.

Comment 4 Michael Wiktowy 2007-04-26 18:58:05 UTC
This problem is not limited to MacBooks. I see the same thing happening on a
Dell Precision 690 Workstation. If I am using a USB keyboard, you cannot switch
option in the bootloader for the LiveCD 7 test4. If you use a PS2 keyboard, it
works fine.

Also, the keyboard works fine with the BIOS since I can use it to select all the
options needed to boot from CD. So keyboard operation and connectivity through a
USB hub and plugged directly into the machine have all been verified and all do
not work with the bootloader.

this bug still happens on fedora 7 live x86


Comment 7 Ra P. 2007-06-18 20:33:31 UTC

Hi again

Good news is that mephis 6.5 64bits boot loader (I think it's a customized grub)
doesn't suffer this bug. Can someone look into mephis changes?

Any new on this?

Comment 9 Michael Wiktowy 2007-08-28 23:34:55 UTC
I know that it is still a problem with my Dell Precision 690 Workstation using
F8test1 LiveCD.

PS2 keyboard works fine, USB keyboard does not.

The workaround in the original bug report doesn't work for me though. Always
dead once grub pops up but does work after it boots to the default.
