How to run chromium on realtime kernel?

Good day.
Sorry for my English and knowledge of Linux.
Set emlid-raspberrypi2-raspbian app app-RT-20150401.the company IMG (from here https://docs.emlid.com/navio/Downloads/Real-time-Linux-RPi2/) to raspberry 2 for using CODESYS.
Everything works perfectly on the chain the laptop → raspberry → engines.
But there is a need to manage the process directly from raspberries. This requires any browser (preferably in full screen). Want to install chromium and run it in the startup in kiosk mod.
After install and run errors out: error NSS libraries and the impossibility to run the display.
I First decided.
But this remained “GTK-warning **: cannot open display”.
Please help. (sorry if this topic has been. hard to search on foreign forums)

Hello!

We have GUI disabled on the RT image by default.

thanks,
was on this link. he helped me solve a problem with the NSS libraries. but with “dpkg-reconfigure locales” did not lead to a positive effect.
I understand I lack the graphical shell to run chromium??? or something else???

You probably have no X.org installed.

nothing. tell me the installation sequence. and then before I worked on systems with existing

now I am installing gnome. to try. I’m moving in the right direction???

hi guys.
Install the new image (the same).
done:
sudo apt-get update
sudo apt-get install chromium-brouser
try to run chromium => 2 errors (NSS and display)
sudo ln -s /usr/lib/arm-linux-gnueabihf/nss /usr/lib/nss
try to run chromium => 1 error (display)
sudo apt-get install xserver-xorg
try to run chromium => 1 error (display)
sudo apt-get install x-window-system
try to run chromium => 1 error (display)

what’s next???

???
maybe then will give you instructions on how to compile RT kernel relevant today… tried it twice to compile it, but the instructions are everywhere older than one year, and therefore did not get…
