Thinkpad volume buttons broken in Mint 7

Postby clownbarf on Thu May 28, 2009 4:59 pm

On my Thinkpad T41 with Mint 6, the volume up/down/mute worked with an on screen display and was synchronized with the volume control applet. You could always determine the volume level with the applet.

When I installed Mint 7, the buttons still control the volume, but there is no on screen display to show where the volume is set. The sync with the volume applet is broken as well. There is no way to see the current volume level.

I have tried all sorts of things from the Ubuntu and Mint forums without success. It appears that ACPI events (as seen by acpi_listen) are being generated for only some of the Thinkpad keys.

Jaunty shows this same behavior.

Any ideas or should this be submitted as a bug report?

Thanks

Linux Mint is funded by ads and donations.

Seems this is a problem many people are having in Jaunty.

Thanks, the bug report led me to a work-around that allows the volume buttons to function. They double step, but at least they work. Here is the recipe and links to the files it uses:

http://archive.ubuntu.com/ubuntu/pool/m ... 7_i386.deb
http://archive.ubuntu.com/ubuntu/pool/m ... 2_i386.deb

remove hotkey-setup
remove acpi-support
install hotkey-setup_0.1-23ubuntu7_i386.deb
install acpi-support_0.114-0intrepid2_i386.deb
lock the version for each of these
mint update will still try to update to the latest versions - don't let it

I have not seen any problems so far...

Same problem here. ThinkPad x41, Linux Mint 7.

Found this tip in a forum somwhere. It worked for me. Don't ask why ;-)

Code: Select all
echo enable,0x00ffffff > /proc/acpi/ibm/hotkey


If is works, you can put the line in /etc/rc.local

Volume buttons on keyboard were not working in Linux Mint 15 Cinnamon with IBM T60
As above to test
Code: Select all
su -
( login as root )
typed
Code: Select all
echo enable,0x00ffffff > /proc/acpi/ibm/hotkey

this worked ... so
(exit su - )
Code: Select all
sudo gedit /etc/rc.local

then added
Code: Select all
echo enable,0x00ffffff > /proc/acpi/ibm/hotkey

after reboot volume and all other hotkeys keys work
:)
