In Ubuntu 16.04 LTS I used to drag home directory window to left or right and that window would then automatically adjust to the half of the screen ( this is called view split left or right ) . In Ubuntu 18.04 LTS this does indeed happen with all windows , but it does not happen with the home directory window . I have even tried the keyboard shortcut for view split left or right for home directory and is not working while it works for all other windows .
Does anyone know how to view split left or right in Ubuntu 18.04 LTS for home directory window?
That's because of nautilus minimum wide that doesn't fits split view. For example if you remove nautilus sidebar or change the display scale it will allow to split left/right. Don't know how to fix it.
I went to Settings->Dock and I enabled the option Auto-hide the Dock . When Auto-hide the Dock is On then view split left/right is working for the nautilus home directory , but when it is Off , it does not work . That solution at least works for me . I have no clue if that is a bug of Ubuntu 18.04 lts or if I messed something with some programms.
