I have just upgraded to 18.04.
Now once I power the laptop on the login screen is multicoloured. With 16.04 I used to have a section for my password. Now I have to click enter and just enter my password with the screen being multicoloured and cannot see the section where I type my password.
The screen that then appears is blue and black and after a waiting period the Ubuntu logo appears and then I have to wait again before picture is restored and can see Activities and Firefox Web Browser. Firefox Browser is so slow. At least with 16.04 I could go into history or tools now I have to guess where I have to go. Can someone assist. Thanks
