Hi, I have the same problem. I also have an NVidia card (and plymouth has never shown me any graphical boot).
But I have noticed something else : if I type the key « (or maybe any other unicod character, I haven't tried), it would crash my gnome session and return to GDM. I believed it was not the same problem at all… But once I do that and my session crashes, I can then type ENTER or the "«" key without any problem ! I would gladly give more details or try some tests if it could help. -- Pressing <Enter> causes X to freeze https://bugs.launchpad.net/bugs/516412 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
