I'm not sure if this is realated, but I think it might be. I'm having the same symptoms on my Lenovo x230 after installing 13.10: the volume and mute buttons stopped working completely and the brightness control buttons do still change brightness but there's no on- screen indicator anymore.
I didn't upgrade using the update manager but did a clean install keeping only my /home partition. -- 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
