Overall Ubuntu setup on ThinkPad Lenovo P1 Gen 2

[altendky]

Previously I've both flailed a lot and found fixes for a couple issues (black screen on resume and brightness control) for running Kubuntu 19.10 on my ThinkPad Lenovo P1 Gen 2. The primary remaining user-apparent issue is the lack of HDMI output. While I did at one point get this working, I have been unable to recreate that scenario.

There is a lot of uncertainty in the present setup and lots of errors even in a Kubuntu 19.10 live boot journalctl log so I am attempting a 'fresh start'.

Resetting BIOS to OS optimized defaults.

It was suggested to use legacy boot but that is not selectable with secure boot enabled.

Disabling Secure Boot.

Legacy is still unselectable but now because of kernel DMA protection.

Disabling kernel DMA protection.

This additionally will change Thunderbolt security level to user authentication and disables Thunderbolt support in the pre boot environment.

Now switching to legacy only.

Switching to legacy only set CSM support to yes.

Before saving and exiting, checking BIOS versions. Lenovo lists 1.27 as the latest.

BIOS reports as 1.27.

Exiting and saving changes...

Since the GPT or NVME or... isn't directly supported in the (non-default) legacy BIOS mode I am going to switch back to UEFI for now. If the legacy path is to be explored more later there's not much overhead it getting back to those settings.

Perhaps this is saying it wants https://packages.ubuntu.com/bionic-updates/xserver-xorg-video-nvidia-435? Though if it does you would think it should have gotten it already. Maybe I misused ubuntu-drivers? https://packages.ubuntu.com/bionic-updates/nvidia-driver-435 depends on xserver-xorg-video-nvidia-435 so installing it directly with apt would have gotten the dep...

That looks better. Apparently how I called ubuntu-drivers above was a bad idea.

And there's the HDMI... :] Brightness control does not have any effect other than the OSD. Black screen after suspend and resume. Plugging in the HDMI cable recovered the laptop display... long enough to type this then it went blank again. Unplug and replug had no effect. Short press power button has no apparent effect. Holding power button to force power off.

Started up again, logged in, just plugging in the HDMI cable extended the display and both the laptop and external monitor are active.
