Can't get Mate to auto-login

[Philippe]

I see same issue in a specific setup. I don’t know why, but autologin doesn’t work with Ubuntu Mate 24.04 in Legacy bios mode, with Radeon GPU and dualboot Windows. Do you have this setup?

Here my same issue, doesn’t resolve, I gave up.

Radeon GPU prevent autologin + blackscreen at boot

Changing the greeter was not intended to solve your autologin problem. It was intended to solve the blackscreen problem, which seemed more important but I guess it was minor compared to the autologin problem. In that case, have you tried this greeter ? It is in the universe repository which is enabled by default. remove your current greeter and install this by invoking sudo apt install lightdm-autologin-greeter
