I installed ubuntu-desktop-mir using apt-get. On boot VTs seem to work fine, but nothing displays. Just a black screen, but my monitor detects input and remains active. I saved dmesg output to a file, but after reviewing it I don't see anything relevant. I've attached it anyway. Let me know if there's more I can do to help.
