In my case, (and others who responded to my question on Launchpad), the problem is that the mouse and keyboard don't work at all, not even if you unplug them and plug them in again.
The live CD works on that system (that is to say, the mouse and keyboard work). Interesting to note that after Ubuntu 12.04 failed, I tried an upgrade to the current version of Mint. It did exactly the same thing. Yet in both cases, the live CD works, just not the upgraded system. I haven't tried a clean install as I have several user accounts I have to migrate off the mahine first and I haven't gotten around to it yet. -- 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/1006145 Title: Logitech Mouse not recognised on boot in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1006145/+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
