Question: I guys, I am new in angular. I created an angular app and in it I have 3 other generated components to test angular navigation. Here is what I need help with, in the "index.html" when I use "[(ngModel)]" in the an input element, it flags no error but if I try to use **"[(ngModel)]"** in any of the 3 created components html file, it gives my error. I have imported "FormsModule" in the app.module.ts.

Please I do I make the ngModel property available in my sub html components?

It will be appreciated if you answer with examples.

Cheers

Answer: 
I've been fighting similar problems today (which is how I found your post). To get rid of the libEGL warning run raspi-config and select the "Full KMS" option from Advanced Options->GL Driver (then reboot). That likely won't fix your styling problem though - I'm seeing styling differences between the Pi (my target system) and my Linux Mint development system.
I have a similar problem and running it in the following way will solve it.

```
sudo python3.7 name.py

```

I guess some privilege is needed from the IDE or the current logged in user.
Although the colors are still more opaque than in Windows and Ubuntu.
