Tab auto-completion doesn’t work for argument for a non root user on Ubuntu 18.04.1

For an ordinary user on Ubuntu 18.04.1 the tab key doesn’t work for a command argument.

For example, entering systemctl sta and pressing the tab doesn’t produce a match for “start status”.

However, it works for the root user. The example below is for the root user:

systemctl sta

start   status

The above functions as expected, but it doesn’t work for a non-root user.
systemctl sta
will not match any argument

Macbook 2015, 8,1 — how to get the keyboard and trackpad working with Ubuntu 18.04? [duplicate]

This question is an exact duplicate of:

  • Macbook (12′ 2015) keyboard and trackpad

    1 answer

Are there any instructions how to install the keyboard and trackpad when using Ubuntu 18.04 on a Macbook?

I’ve tried looking through Google results and I get a lot of Macbook Pro or other strange answers.

EDIT: fixing my grammar does not solve the issue at hand. This is for 18.04, I am not a linux wizard, do they share the same kernal? You marked it as answered. The answer is in regards to 16.04

Chrome remote desktop breaks MATE desktop on Ubuntu MATE!

I’m using Ubuntu MATE 18.04. I’m trying to install chrome remote desktop. I have downloaded a deb file and when I install it, everything is fine until I reboot, but after that when I login, I get an error saying “Could not acquire name on session bus” on a blank black screen. I click “close” woth my mouse pointer and then there is nothing left on the screen except the pointer. I can still open a terminal with Ctrl+Alt+T. I tried following instructions on the net which advice me to create .chrome-remote-desktop-session file, and edit .profile, and after doing that it still remains the same.

Any advice?

I searched for any type of snipping tool in ubuntu. I found Shutter & installed it. But my Ubuntu launcher didn’t show its icon.

When I launch Shutter from terminal, my PC run slow & terminal showed hundreds of warnings. Is there any other snipping tool (Without Shutter) for Ubuntu 16.04?
