I installed LXDM and LightDM, I couldn’t login from the DM in either cases, so I decided to run LXQt using startx which worked, except I couldn’t sudo from the terminal emulator inside LXQt, while I was able to sudo normally in tty, I’ve tried enabling elogind, nothing changed, my user is in the wheel group and my system is up to date
What shell are you running in your terminal? If I’m remembering correctly, it’s recommended to set the shells during the installation, so that could be the issue here.
Both bash and fish are returning incorrect password upon trying to execute any command with sudo
