I think you have typed the command wrong. The symbols around uname -r must be backticks (`) not quotes ('). The backtick key is next to the 1 key at the top left of the keyboard.
If you still can't get it to work, try changing `uname -r` to $(uname -r). -- Black screen, and bad usplash.conf https://bugs.launchpad.net/bugs/150930 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
