Description OlafLostViking 2015-10-16 17:42:25 UTC

Okay, this is going to be a vague one...

I have a password that I am able to enter very fast and since I am already using it for a long time, I (almost ;-) ) never fail to enter it correctly. Logging in at the console, logging in via SDDM or using sudo works basically every time.

Unlocking the screen of my plasma desktop in a KVM/QXL/Spice VM fails almost all the time, however. At first I thought it's my fault for sure. But testing it over and over, it showed that I can enter this password correctly in console/sddm etc. as fast as I wish while I have to pay attention to enter it quite slowly (compared to the console - approx. 3 characters per second or less?) in the plasma screenlocker to have it accepted.

I even changed the password to another similar complex one and tried it again after training it for some time. Same effect.

I totally understand this is very vague... but perhaps you can simply try to reproduce it by setting a password (in my case 8 letters, upper and lower case, number and special character - I know there are better ones; this is historical and only used for my testing VMs ;-) ) and try to torture the screenlocker with it?

Perhaps it's just an artifact of the input redirection over KVM/Spice? I couldn't test on a "real" machine yet, as I cannot switch to the 5-branch for now. If really nothing can be found, adding the "show password" button used in the native password dialogs could be probably helpful.

Reproducible: Always

Steps to Reproduce:
1. set complex password
2. learn to type it really fast
3. get rejected by screenlocker

That's very likely. It will also be difficult to debug. The only idea I have is to provide you a variant with showing the actual password, so that you can verify whether the entered text ends up correctly in the input field.

Sure. I'll install whatever you have ;-)

(e-mail in German would be fine if you want to send sth)
