Various outputs

This is a very similar issue to others posted about the Lenovo D330 in bug 109267 and bug 108826.  

I've tried multiple distributions.  Live disk Ubuntu 19.02 works but after install, screen boots black.  If I run nomodeset in Grub, Ubuntu will boot but with screen rotated 90 degrees left.  Xrandr does not function.   

My suspicion is the patches created by Hans de Goede will remediate the issue however my specific Lenovo model is not listed and would need to be added.

Can you please attach dmesg from boot with with kernel parameters drm.debug=0x1e log_buf_len=4M?

What is the kernel version? We recommend to verify the issue with drmtip (https://cgit.freedesktop.org/drm-tip).
