Hi. It seems not only Dell laptops have been affected. I'm using Lenovo ThinkPad X280 with Lenovo USB-C dock and this bug affects me. But the steps I reproduce the bug is different.
For the reproduce steps on Lenovo ThinkPad X280, please refer to bug #1813763 (marked duplicated) ^ Thanks. -- 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
