Dual booting ubuntu on chromebook

Hello everyone,

Im trying to dual boot linux on my chromebook. I have an acer chromebook 15 CB3-532.

I followed this guide: https://www.linux.com/learn/how-easily-install-ubuntu-chromebook-crouton

However when i come to the part where you type:

sudo startkde

it starts for a brief moment, then the screen turns black and it says:

'Cannot call D-bus. Can you call d-bus?' and there is 1 button i can press that says 'okay' and then it exits back to chrome os.

Then this is the text that appears in the chrome os terminal:

chronos@localhost / $ sudo startkde
