Display is not initialized on i5 3gen - gtx960

Hi I wanted to install newest version of ChimeraOS, unfortunately it has some problem with (most likely) display initialization.
My setup:
i5-3450
GTX 960

I tried to do some troubleshooting but:

Web interface works, but since i have no luck with display init i cannot pass "Please enter the password shown on your display to continue". So i also cannot go straight into ssh because i cant add new ssh key.

I tried terminal directly on machine but it constantly switches me back to main screen (which has only blinking underscore) so its really hard to use it because i constantly need to switch back into TTY)

What i can do to grab some logs?
