I also have a rather recent Lenovo X1 (Touch) Type 3448-1Q6, and just upgraded from 13.04 to 13.10. For me the three buttons (mute, Volume up and Volume down) are working fine after the upgrade.
So it may be a problem related only to a certain type of X1 HW. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1242259 Title: Thinkpad x1 Volume up down and mute keys stopped working after upgrade to Ubuntu 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1242259/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
