If you're talking about these:

VGA switcheroo: detected DSM switching method \_SB_.PCI0.P0P1.VGA_ handle

They're usually from the nouveau driver probing the _DSM method using
the wrong data type for Arg3.  But that's ok because asus-switcheroo
already loaded:

Found VGA device 0000:00:02.0 (\_SB_.PCI0.VGA_): IGD
Found VGA device 0000:01:00.0 (\_SB_.PCI0.P0P1.VGA_): DIS
Asus switcheroo: detected DSM switching method \_SB_.PCI0.P0P1.VGA_ handle

It seems you want to use the proprietary nvidia driver, so you
probably want to blacklist nouveau and load asus-switcheroo with the
dummy-client=1 option.  The only way I've tried it is to then load the
nvidia kernel module (which I see getting loaded before
asus-switcheroo in your dmesg, not sure if it matters), switch to
discrete, then start X with the nvidia driver.  Thanks,
