I have a problem with autologin in my Ubuntu 17.10. In settings I have uncheck "automatical login" but still, when I turn on system then automatic log in. I looking for a solution in the internet but still nothing. Please help me guys.
I am wondering if you've given a password to the user. If not, please do that. If this is not the problem, then I will recommend doing a clean install of the OS again.
This is my personal opinion that you should move from Ubuntu 17.10 to some older version like Ubuntu 16.04.
I installed Ubuntu 17.10 only to delete it in 2 days. So many softwares are not available for this Ubuntu version. It is not a stable release. My display couldn't work properly in that OS. It was sometimes like this image: Image. So many flaws in that OS.
