- I start my computer ;
- The loading screen appears ;
- The login screen appears (but logging in will not work) ;
- The screen turns black with underscore ;
- The login screen reappears (logging in will finally work) ;
- I’m logged in.
It has been like that for a while, I expected this bug to be found & fixed eventually, but after running an update today, it still hasn’t, which is why I’m now posting here.
So, when the login screen first appears :
- either I have time to type my password & press enter, but afterwards the login screen still disappears then reappears as if I never tried to log in ;
- or I’m still typing the password while it disappears then it reappears as if I never started typing ;
- or I wait for it to disappear & reappear, and only then I can finally log in.
What to do ?
Thank you
Hi,
Here’s what I found :
