Lenovo T60 (1951-FEG) Key does not work sound (VolumeUp, VolumeDown, Mute)

Hi ,

try to use the acpi_osi= parameter to the grub menu . How ?

Open the terminal (CTRL+ALT+T) and copy-paste this command

~$ gksudo gedit /etc/default/grub

search and find the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and change it to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="

save the document and then run in terminal this command

~$ sudo update-grub

Reboot and see if Fn keys work.

IF NOT , then give here the results of this command

~$ cat /etc/default/grub

Thanks

Thanks for the reply, but unfortunately did not help.
All functions Fn worked before.
But the volume keys in a separate block of keys.

I also had this same problem: volume/mute keys of the T60 wouldn't work on Ubuntu 12.10. Or actually the did, but I had no visual return.

Anyhow, the solution I found in the UbuntuForums (for Oneiric Oncilot 11.10, but....) worked fine for me:

1. Open the file with a text-editor such as gedit:
sudo gedit /etc/rc.local

2. Add this line before "exit 0":
cp /sys/devices/platform/thinkpad_acpi/hotkey_all_mask /sys/devices/platform/thinkpad_acpi/hotkey_mask

3. Save & close.

Reboot and you're good.
