Bug Description

Description:
Checkbox-ng would adjust the graphic mode from "Performance" to "Power Saving" during client-cert-20-04 testing, and then the screen would stays at Boot logo.

User need to re-connect the monitor to integrated GPU to switch the graphic mode to "Performance" mode to continue rest of testing.

My question is shall we test integrated GPU while a discrete GPU installed for a Desktop/Tower server/Rack server? If not, we should not list the test cases for integrated GPU.

Steps to reproduce:
1. Connect an external monitor to dGPU.
2. Power on system and boot into OS.
3. Make sure the graphic profile is in performance mode.
stanley@stanley-ThinkPad-T490:~$ prime-select query
nvidia
4. Run client-cert-20-04 test plan.
Note: the screen would stays at Boot logo after checkbox-ng switch the graphic mode to "power saving" mode.

Test environment:
A system w/ iGPU and nVidia GPU installed.

Just to be clear, this is a desktop thing, Server does not test any graphics output as Ubuntu Server is intended to be run headless.

We can't ignore a video port. They all have to be tested per the certification guide.
If by switching to the integrated card the monitor has to be reconnected, I don't see a fix on checkbox side (or maybe a warning in the test desc, but that will be barely noticeable if the test if automated). I'd rather add a note in the ODM testing document to either have two monitors or a setup with a picture-in picture setup to avoid entering "power saving" mode.

As discussed with Sylvain, base on comment#3, to mitigate the problem, the best approach will be connected 2 monitors, one on DIS card, the other on iGPU.
AI, have QA team to try it to see if the issue could be mitigated or not.

For Stella,
SKU: Z2 G8 (I+N)
in performance mode, both iGPU and dGPU works well
--
use command swtich to powersaving mode,
only connect display in iGPU then boot --> stuck on login page (can't login with correct password)
connect 1 monitor in iGPU and 1 monitor in dGPU --> stuck on login page (can't login with correct password)
