I can confirm the same bug also for 5.4.0-45 and for 5.4.0-48 and also a workaround. In kernel 5.4.0-45 it is happening only one out of 3-4 times directly on boot. In all the other 2 kernels (5.4.0-47 and 5.4.0-48) it is happening on each cold boot.
Workaround: after first cold boot from the login screen I restart the computer. After restart the laptop display is available. If I shut down and power on I still have the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895935 Title: eGPU setup - internal laptop display not usable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1895935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
