When my system boots up, and I click my username, and enter my password, the login attempt fails. However, when I try the exact same password again, I can successfully log in. What could have caused this? I am using the latest arch Linux on the latest gnome3/gdm.

    does it happen if you try to login over SSH or via the console? – thrig Dec 26 '17 at 22:09
  • no it does not. – Sreehari S Dec 28 '17 at 1:59

I just realized that for some reason, the first key I press on my USB keyboard does not get registered.


My Fedora system has had this since version 26 or so (on 31 now). I noticed that Gnome logins don't start working until the text console login prompts on PTY 2..6 become available. Likely, the GDM login screen just pops up too early.

  • You can check if any of the text consoles are up before attempting a graphical login (by pressing Alt-Ctrl-F2, for example, and then back to Alt-Ctrl-F1) – dwagelaar May 18 '20 at 14:25
