Youtube – How to change the YouTube channel name

Your question is split into two parts, and so shall my answer. :D

Firstly, you don't necessarily need to put your real name (although it is a requirement by Google). You can just put your nickname and make it look convincing that it is a name, and you should be okay with it.

If you don't need Gmail, you can just follow the steps here and you should be alright.

Also, you don't necessarily have to link your Youtube account with your original Google account. While it is the default for new accounts created, you can simply disconnect it in your account settings, as stated in this question.

Secondly, did you check if you disabled Javascript when browsing Youtube? I am not exactly sure what the problem is that results in your "screen fading away", but do check for the common browser issues regarding the browsing of the site. If you still can't fix it, I would suggest contacting Youtube directly to ask your question so that it can receive more professional help.

You can change your display name by doing the following:

1. Log in to your desired account on YouTube.
2. Click on the down arrow on the top right hand corner next to your profile picture (if you have one).
3. Select "YouTube settings". Click on "Advanced" under "Account Information".
4. Click "Disconnect with Google+" account. Note that with this, you are creating a channel for yourself with a separate username.
5. After completing the steps, you will have your own username. This username will become your display name afterwards.

Note however, that you cannot actually set a proper display name with spaces if you use this method, but it does separate your real name from your YouTube account.

Alternatively, you can just go to your Google Account and change your real name to something else (though it is going to change it on every single Google product you use, especially your Gmail). You can follow these steps:

1. In YouTube, click on the down arrow on the top right hand corner next to your profile picture.
2. Under "Google account", click on "Profile".
3. Assuming you have your Google+ account created, click on your name in the profile page and change it to your desired name accordingly.
