Nouveau blacklisted but loaded

Hi I am trying to use Ubuntu-Prime for ubuntu 18 on an asus laptop with 2 GPU (intel & nvidia).
I found the power consumption of the computer to be way too high when I reboot with only the intel GPU (using prime-select intel or using nvidia-settings).
I found that the nouveau driver was loaded despite normally not used:
$ gpu-manager | grep nouveau
Is nouveau loaded? yes
Is nouveau blacklisted? yes
Skipping "/dev/dri/card1", driven by "nouveau"
Skipping "/dev/dri/card1", driven by "nouveau"
Found "/dev/dri/card1", driven by "nouveau"
Skipping "/dev/dri/card1", driven by "nouveau"
I tried to blacklist it and also have a kernel startup option to prevent nouveau from being loaded yet it still loads. This seems very un-linuxy to me.

Is the nvidia driver loaded? Post the whole output of gpu-manager. Blacklisting doesn't prevent something from explicitly loading a driver, so something must be pulling it in, maybe because Nvidia's not loaded.

No nvidia is not loaded. I would actually like my discrete GPU to be off to prevent it from draining the battery.

What video driver are you trying to use, Vesa? See askubuntu.com/questions/849481/… There might even be another framebuffer fallback driver possible.

I do not see why I would need a driver for a graphic card supposedly off ?

Digging the issue, Ubuntu 18 has a conflicting service (with prime) that actually loads a driver for the discrete GPU : ``` systemctl status nvidia-fallback.service ◠nvidia-fallback.service - Fall back on nouveau if nvidia is not loadedLoaded: loaded (/lib/systemd/system/nvidia-fallback.service; enabled; vendor preset: enable Active: active (exited) Process: 1007 ExecStart=/sbin/modprobe nouveau --config /(code=exited, status=0/SUCCESS) Main PID: 1007 (code=exited, status=0/SUCCESS) XX systemd[1]: Starting Fall back on nouveau if nvidia is not loaded

I found a way to disable nouveau and get my battery life back when using prime with intel graphic card :
2 bugs in Ubuntu 18 are concerned :
1. Prime fails to turn off discrete GPU (known issue).
Make sure that your discrete GPU is connected to PCI port 0000:01:00.0 (using lspci -vnn | grep '''[030[02]]' for instance)
Change /etc/systemd/system/display-manager.service.wants/nvidia-prime-boot.service and replace the current execstart (referencing vgaswitcheroo which is not usually available by ExecStart=/bin/sh -c "echo 'auto' > '/sys/bus/pci/devices/0000:01:00.0/power/control'")
2. nvidia-fallback loads nouveau when nvidia is not loaded
Even if we are willing not to use the discrete gpu !
Disable the following service which loads nouveau driver when nvidia driver is not loaded : sudo systemctl disable nvidia-fallback.service
