As indicated in the title, I'm having some issues when booting my RPi (3b). More specificly, when loading the GUI desktop, it keeps asking me for my password. I give the correct one, it shows a black screen then asks for it again.

I made the "investigations steps" I found here https://raspberrypi.stackexchange.com/a/57366/101006 and here is what I found in the lightdm log file: lightdm log

lightdm log end

Note: The second picture serves only to show the end of the highlighted line

I also tried to change the rights of the .Xauthority file with the chown command but it doesn't help. Idem when I try with "pi":

sudo chown -R pi /home/pi

sudo chown pi:pi .Xauthority

None of these command help.

For the next of the answer I don't know which package to remove with dpkg purge and I don't want to remove some files that I won't be able to re-install after that.

I don't know what to do now to avoid being asked for my password, any idea ?

  • I didn't know how to copy and send it somewhere I could get it since none of the default interface network works ... May 15, 2019 at 7:41
  • Ah.. ok. You took photos from the RasPi monitor, isn't it?

  • When it asked me for the password, I made Ctrl+Alt+F1 and I went into the terminal. Then I opened the lightdm log file and I took the picture with my phone May 15, 2019 at 7:49
