I’ve installed Ubuntu 18 LTS on my Laptop. I’ve problem on login screen, I’ve failed login on my first login on my ubuntu 18 desktop, then I tried to re-login (second login) using correct password, I think login success but only showing blank screen. But, if on first login password correct, login success and no blank screen. So that, if on first login failed, I must directly shutdown my laptop with poweroff button and wait for booting again until login screen appear and then login using correct password.
Need enlightenment. Thank you.
