The latest build does not work anymore for my T430, internal and external displays don't activate at all. Yesterday with the build dated 04-06 or 06-06-19 it worked. I'll try to reproduce later today.
Though I really appreciate the progress. Thanks!
Edit: Works now. I most probably missed to flag "Load proprietary blob repos" after a 'make distclean'.
So you're using Optimus? Please tell more about your setup. Which nvidia driver you use, kernel version, how stable it is, etc, etc. This is valuable information.
As my T430 machine is my daily driver and just occasionally got hacked on during the OSF-Hackathon in Bochum. I did not investigate further. But now have got my backup machine running, so I'll might start hacking again.
I am and was using the open source nvidia driver in addition to the open source intel driver as far as I remember.
In the end the coordination between Intel and nvidia did not work out. I got a lot glitches and freezed screens. But that could also be a artifact of using wayland. I have to check again the next time the T430 I open the machine for hacking.
