I have 2 systems running Buster with encrypted disks. The first system was upgraded to Buster; I think the original install was Stretch. The second system was installed with Buster.
With the first system, when I enter the passphrase at the "please unlock disk" prompt, there is no visual feedback. With the second system, I get a "*" for each character that I type. Is there some configuration option I can change on the first system so that it behaves like the second one? Alternatively, is there a way to tell the first system, on a one-time basis, to give me feedback as I enter the passphrase? The reason I ask is that this morning I was unable to unlock the disk of the second system. The problem was that the keyboard was not working for one of the characters in the passphrase. I was able to figure out the problem because I noticed that I was not seeing a "*" when I pressed that character. If the keyboard problem had occurred with the first system, I would have had a much harder time figuring it out. thanks, mike
