Question: I know there was an old bug back during Ubuntu 9.x where the cursor wouldn't change because of compiz. I am now running Ubuntu 14.04 and the bug has now decided to rear its ugly head again. I am using an old cursor that looked decent with a theme and I now switched themes and my current cursor doesn't look good with it. I tried changing it with unity tweak tool but when I apply the cursor, it won't change but it will use them in certain programs such as Firefox. Is there a way to fix this?

Answer: 
The default setting in Debian (and hence Ubuntu) for OpenSSH Server is to deny password-based login for root and allow only key-based login. Change this line in `/etc/ssh/sshd_config`:

```
PermitRootLogin without-password

```

to 

```
PermitRootLogin yes

```

And restart the SSH server:

```
sudo service ssh restart

```
To me, works changing (Ubuntu 18.04):  

* `sudo nano /etc/ssh/sshd_config`

---

* `PermitRootLogin prohibit-password` to `PermitRootLogin yes`
* `PasswordAuthentication no` to `PasswordAuthentication yes`

---

then, restart ssh service:   

* `sudo service ssh restart`

Thanks!
