[Bug 1813815] [NEW] can't enter password in shell

[radiomog at yahoo.com]

Public bug reported:

1. I press CTRL+ALT+F1 to enter the shell ( I need to shutdown x-server to install video driver)
2. Shell prompt for user name.  I type in my user name and press ENTER.
3. prompted for password, but before I can touch the keyboard, the system acts as though I have, and cycles through the prompt several times saying the password was incorrect. Each time it cycles as though I have entered something, and I have not.
4. Screen blanks and goes back to the shell prompt asking for user name.


I don't have a problem in terminal (CTRL+ALT+T), nor upon reboot, when entering shell from recovery mode.  I also tried different keyboards in the Shell, same thing.  this has only happened recently,
I periodically update my video driver, and until today, the process worked without a problem.
