Section "ServerFlags" Option "AutoAddDevices" "False" Option "DontZap" "False" EndSection and delete Option "AllowEmptyInput" "off" in Section "ServerLayout" -- 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
