  • Setting->background. What is the difference between lock and lock-in screen? When you lock the computer, you need to go to login screen to enter the password. Shouldn’t they be th same?

    No, it's good to make the images size same as screen resolution...that's why asked.. Even if you specify lower resolution or sizes it will cover full screen. For better quality if we can match image size n screen resolution. It's good.

to change the login screen background in Ubuntu 18.10 with default Display Manager that is gdm3



we need to edit the gdm3.css file.



open the file with your favorite editor, mine is gedit. so
sudo gedit /etc/alternatives/gdm3.css



go to line number around 1981 and find the below content.



#lockDialogGroup 
 background: none;
 background-color: none;
 background-gradient-direction: vertical;
 background-gradient-start: #6D2169;
 background-gradient-end: #370026;


change the content with



#lockDialogGroup 
 background: #000000 url(file:///home/pratap/Desktop/1.jpg);
 background-repeat: no-repeat;
 background-size: cover;
 background-position: center;


here in the line number 1982 url(file://put your actual image path)



save the file, close & reboot to see the change.

Edit

for 18.04 same method, only line number varies 1814,



#lockDialogGroup 
 background: #2c001e url(resource:///org/gnome/shell/theme/noise-texture.png);
 background-repeat: repeat;


replace the above content with



#lockDialogGroup {
 background: #000000 url(file:///home/pratap/Desktop/1.jpg);
 background-repeat: no-repeat;
 background-size: cover;
 background-position: center;


here in the line number 1815 url(file://put your actual image path)

Confectionery

Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
