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

```
Hackers will bang away with root user trying to brute force their way in. If you are going to allow root logins, you should definitely install Fail2Ban, or something similar to protect against brute force attacks. Also use a very hard to guess password without the use of common words. 

And, as Vaindil pointed out, a key based login would be far superior. They are not very hard to setup. Here's a link to setup key-based login using PuTTY on windows: <https://devops.profitbricks.com/tutorials/use-ssh-keys-with-putty-on-windows/> . But there are lots of others if you are using a different environment to login from.
