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:
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 ?
