This has something to do with using DisplayPort monitors (through the two DisplayPort connectors on the laptop dock). When the laptop is undocked and a single external monitor connected to the HDMI port on the laptop itself, nouveau works fine. Dock the laptop and suddenly it can't boot any more.
To recap: linux 4.13 + nouveau + 2 DisplayPort monitors = works fine linux 4.15 + nouveau + 2 DisplayPort monitors = unbootable linux 4.15 + proprietary driver + 2 DisplayPort monitors = works fine linux 4.15 + nouveau + 1 HDMI monitor = works fine -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763189 Title: kernel 4.15 breaks nouveau on Lenovo P50 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763189/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
