I'm hitting this bug too, using a Lenovo Thinkpad T470s (20HF0047IX); i'm using a docking, but also without the pc boot but i get black screen.
I'm using 'signed' kernel, can i safely install the (unsigned) test 4.15.0-45 kernel? Kernel -43 works as expected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813663 Title: External monitors does not work anymore 4.15.0-44 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813663/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
