Help : Layman configuration for Raspberry Pi 5, Linuxcnc 2.9. and Mesa 7i96

with network manager installed, i cannot reach the network interface file like earlier. 
i tried to use
> sudo service NetworkManager stop
but then i cannot enter the network menu in the sudo menu-config anymore

to edit the file in the etc/network folder i cannot save whatever i have edited. and i would really like to edit it through the sudo menu-config rather than messing up any files manually through the filemanager

whats the go around? 

and as i understand, you suggest to comment out the following lines in the interface file? correct? or will i also have to edit something in the Wpa supplicant? (once again i would prefer doing it through the menu-config)

Once you have networking setup you can configure your Mesa card as you would for a normal PC, there are plenty of threadson the forum regarding this subject, there is nothing particular to the RPi platform in this respect.
 

i have run into a locale issue. what should be my locale set to? i am based in Germany. 
from Locales by Behai, i set up my locale as en US.UTF-8 UTF8
but the issue persists. 

for the locale issue? something needs to be manually set here or?

ahh.. as explained in this thread, you have to press spacebar to actually select the locale in the sudo menu-config (ha ha)

by typing locale in the terminale, the newly set locale can be confirmed. I have fixed the locale issue now.

so back to the interface settings and network manager.. i still need help there. Thanks again to all!

Ok once again.

For the interfaces you want to configure via Network Manager make sure the interface does not have an entry in the network file.

It is quite simple.

you are right, it was quite simple indeed.

i opened the file interfaces file with
$ sudo open /etc/network/interfaces

commented out every line under #wireless

(managed to save the file this time since i was with sudo previlages.. unlike previously where i opened the file manually through the file manager)

$ sudo reboot

now wifi shows up under network manager gui, and it can be turned on and off easy.

thank you!
