@mcat95 have you come across any kind of workaround for this issue other than using a wired or builtin (laptop) keyboard?
I am experiencing this same issue, same scenario (15.04 upgrade) with a Logitech K800 wireless keyboard. Happy to provide detailed system information if it is useful, but my config appears to be very similar to mcat95's. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450781 Title: Wireless USB keyboard does not work when entering password on encrypted disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1450781/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
