As the title says, I have been using Ubuntu 10.04.1 LTS (Lucid Lynx)for a while now and there has been no problems so far. However,after shutting down yesterday night, I woke up this morning and couldn't use it. Problem is, it boots, loads, everything appears (system monitor watch thing is going, clock's seconds is ticking, doesn't seem like a freeze), but I can not click nor type. The cursor does move as I move my mouse, but simply can not click. Another thing that never happened before is that the keyring appears, which never does upon boot ups. Any help please
