This has effected me as well. I have a Lenovo X1 Carbon with Nvidia GTX 1650. New Ubuntu 20.04 install.
When I boot up, the built-in screen does not work and it hangs with the Lenovo and Ubuntu logo. When I boot up with an external monitor via HDMI, it boots up BUT build- in screen does not work. If I use the Inter Drivers (radio button in the NVIDIA X Server app) it will boot with the built-in screen working BUT not HDMI / DP working. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874194 Title: Ubuntu 20.04 HDMI connected, no boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
