Ubuntu Desktop Noble live was tested in an HP Probook 640 G4 with

- Intel i5-8250U CPU
- Intel 'UHD Graphics 6'
- built-in resolution 1366x768

connected to an old Samsung monitor with 1920x1080 resolution. The external screen is connected via HDMI (a HDMI to HDMI cable). This is the same setup as in comment #9 report except that Ubuntu Desktop was tested instead of Lubuntu.

1,2,3. I booted in UEFI mode with secure boot, when the external Samsung screen was connected. The grub menu was only shown on the internal screen but starting with the splash the external screen worked as expected.

This test shows that standard Ubuntu Desktop Noble works while Lubuntu Noble is flaky in a laptop when an external screen is connected.

See more tests of installed as well as live systems with an external screen connected at bug report #2047456 "Installed Lubuntu Mantic and Noble are flaky with two screens"
