Arrow keys, Home, End, tab-complete keys not working in shell
That probably means that the new user account was created with /bin/sh as its login shell (which symlinks to the dash shell by default) instead of /bin/bash - you can change a user's login shell with the 'chsh' command
sudo chsh -s /bin/bash <username>
(you will need to log out and back in for the change to take effect). You may also need to copy the default .bashrc from /etc/skel to get the color prompt.
In future you might want to use the 'adduser' command instead of 'useradd' - it sets up a more complete user environment including things like a default .profile and .bashrc - as well as setting the login shell to 'bash'
I was unable to use tab completion when connecting via VNC to a headless XFCE4. The answer listed here did not work but this did:
Edit Keyboard Shortcuts in xml file:
sudo nano ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml
<property name="<Super>Tab" type="string" value="switch_window_key"/>
Change it to:
<property name="<Super>Tab" type="empty"/>
Logout/reboot and should be good to go
I just installed Vim and everything was solved. At first, I thought that it was installed on the original version of Ubuntu since I was able to use Vi command, but it was not the case.
sudo apt-get install vim
solved the problem.
