Hi, I'm running a HP Pavilion zv6000 - series zv6100 and face the same problem.
The volume goes up to full or empty when I touch the volume dial, and the OSD keeps flashing and the keyboard gets disabled/freezes, but the mouse works. Also: . to stop the flashing OSD and setup the volume, hit Volume key Up or Down and press twice the mute volume . hiting Ctrl+Alt+F1 and back to F7 unlock the keyboard. Everything worked fine on 7.10. This is a fresh install of 8.10. I checked theTroubleshooting page but nothing important. Keys are well recognized, (keycode 111 XF86AudioMute, 122 XF86AudioVolumeLower and 123 XF86AudioRaiseVolume). Xorg is empty from scratch install. The card is an ATI. Seems that people in bug #272292 faced the same problem. Attached are the needed debug files. ** Attachment added: "gconf" http://launchpadlibrarian.net/23009172/gconf -- volume control doesn't work with HP laptop volume buttons https://bugs.launchpad.net/bugs/311353 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
