Testing Instructions

Applicable Targets

  • Orin AGX aarch64
  • Orin NX aarch64
  • Lenovo X1 x86_64
  • Dell Latitude x86_64
  • System 76 x86_64

Installation Method

  • Requires full re-installation
  • Can be updated with nixos-rebuild ... switch
  • Other:

Test Steps To Verify:

DARP11-B:

  1. Boot into Ghaf
  2. Wait the default suspension timeout (15 minutes) and verify device does not suspend
  3. Try to suspend the device manually, verify nothing happens
  4. In guivm terminal, run systemctl status system76-power.service and verify the service is running
  5. Try to change power profiles via the battery widget in the top right, verify power profiles can be selected
  6. Try to adjust the backlight brightness via the keyboard shortcuts FN+[F8/F9], especially while holding the buttons down - the adjustment should be fast.

All x86 targets (optional):
These steps might require that there's no previous cached config under /home/appuser/.config/google-chrome
On fresh installs, this is a non-issue, but on rebuilds you may have to ssh into chrome-vm or business-vm and rm -rf /home/appuser/.config/google-chrome

  1. Verify no regression in Chrome/Trusted browser performance and behavior
  2. Verify images load, videos play, and WebGL works as intended over at https://webglsamples.org/aquarium/aquarium.html

We could also potentially enable services.system76-scheduler.enable = true on gui-vm and/or host.
I experimented and verified it runs properly on both guivm and host, but haven't checked the performance/battery life impact.

Tested on DARP11-B (new image)

  • Suspension is disabled
  • Laptop is automatically locked after 5 minutes but not suspended after 15 minutes
  • system76-power.service is running
  • Power profile can be changed
  • Brightness adjustment is smooth

Tested on Lenovo-X1 (nixos-rebuild switch)

  • No regression in Chrome or Trusted Browser based on a quick test (removed the Chrome config first)

Pre-merge pipeline

  • One systemctl service (setup-ghaf-user.service) failed in gui-vm for Dell and system76. This happens sometimes and can be ignored.
