Is it possible to logout the current user and immediately login the same user again with one command in the terminal?
I would like to open the terminal from the login screen. In previous Ubuntu releases I just used Ctrl+Alt+F1. However, when I press Ctrl+Alt+F1 in 18.04, nothing happens, the login screen just stays as it is. All other combinations with F-keys (F2 to F12) also have no effect whatsoever.
What key shortcut do I have to press to open the terminal from the login screen?
I installed Master PDF editor 4 from a .deb file downloaded from the official webpage on Ubuntu 16.04. The installation via Software was successful without any error message. However, when I start the program from the terminal I get the following error message:
masterpdfeditor4: error while loading shared libraries: libsane.so.1: cannot open shared object file: No such file or directory
Does anybody know how to resolve this issue? I already executed
sudo apt install libqt5printsupport5
sudo apt install qt5-default
sudo apt install --reinstall libqt4-svg libqt4-script libqt4-scripttools libqt4-sql libqt4-test
as suggested in other forums, but still the same error message appears.
