I have the same Logitech set and to make it work I had to unplug and then plug again the Bluetooth receiver and I got back the keyboard and mouse, pretty much the case outlined on the link posted by Pascal.
If there's anything else needed I'd be glad to help. It would be also good to know the bug upstream if it ever was raised. -- Bluetooth Keyboard/Mouse won't work in LiveCD https://bugs.launchpad.net/bugs/123920 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
