[KDE neon 6.3] I have to wait for the login screen to black out and reappear before logging in (jlai.lu)

  1. I start my computer ;
  2. The loading screen appears ;
  3. The login screen appears (but logging in will not work) ;
  4. The screen turns black with underscore ;
  5. The login screen reappears (logging in will finally work) ;
  6. 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

Do the login screens look different from one another?

As far as I know KDE Neon isn't really meant as a daily driver. A different distribution would probably be more stable.

Nope

KDE Neon isn't really meant as a daily driver

Why not ? It's Plasma and KDE apps on a Ubuntu LTS base with none of Canonical's crap.

And all KDE apps work on it, while other distros running KDE don't necessarily support all KDE apps, especially Discover.

Do you have multiple monitors? My laptop behaves in a similar fassion when the screens turn off from inactivity and i want to log back in. I have 2 monitors attached that take different amounts of time to wake up and each time sddm rearranges the screens.

The login prompt is "per screen" and gets erased when a display is attached (or wakes up)

[–] KaKi87@jlai.lu 1 points 4 days ago

Nope, just the laptop monitor.

are you using any sddm themes? splash screens?

Also check/share the logs (you can use ksystemlogs or gnome logs if you prefer guis).

Nope, all default.

I'm guessing you don't want the last few lines, what am I looking for ?

Not sure tbh but probably anything around the time you experience the issue. Check the time when the issue occurs, then look at the logs from around that time for any errors warnings. That should at least give you a clue.
