My desktop is not showing its icon

please help me out

had tried app installation three time. i am installing on ubuntu 18.04

In v12 (develop branch), we have refactored desk. New desk will have plain structure.

so if i want old screen than is there any way to replace new with old?

The Desktop is dead now in v12, welcome to the new changed look :slight_smile:
