Re: [Solved] adb server prevents Nvidia suspend
don't understand how did you figured it out
"Elementary, dear phoenix324:"
We kinda established that adb doesn't use any GPU features anyway, the strace didn't show any suspicious acces in that direction either, not anything related to power control.
But: I saw that it unconditionally listens on all USB hubs. I knew that some newer nvidia GPUs have xhci hubs, generating a possible intersection.
You confirmed that your GPU has one and then we just needed to figure a way to make adb not touch that device.
Disallowing the nvidia driver access to it caused the GPU to become perma-active, so the next best thing was to just hide the device node.
