did you move that xorg.conf and reboot yet?
yup, seems to work fine. Glitchy snapping is also fixed, could it be related?

because that conf file was causing issues, im surprised you even got to a desktop with that xorg.conf in there.
now that everything seems to be good, can you post these outputs. the last ones were no good do to that issue, i just want to confirm that optimus-switch is working properly, your the first person to use it on a ryzen/nvidia laptop.

If your USB drive is only temporary, for testing Manjaro, then fine.
If you want to actually use it as a portable installation for several random hardware, it is not a good idea to have nvidia non-free drivers installed. Only free (video-linux).

looks good, thanks for the feedback. let me know how it performs after using it. since it's on a usb i wouldnt expect too much but now you know since it works you can install it on a real drive. any tearing?
when you get a chance to test amd-only mode sudo set-amd.sh it would be greatly appreciated if you could post those same outputs.
I'd like to install it on the ssd, but I'm having difficulties. The installation flash drive doesn't do anything graphical, so I tried to manually install manjaro with the tty (Since optimus-switch is only effective after reboot it doesn’t help for the installation media.) but I messed up the grub...
When booting the laptop, it brings me to some grub console, which tells me to load the kernel but doesn't tell me how... When I type exit it simply boots windows.
So even if it did boot manjaro I would still have not installed the graphical environment and to be quite honest I don't want to do that manually.
Lol! Got it to work.
- Insert installation media
- Boot
- press
ctrlaltf2to enter the tty - Login manjaro/manjaro
Commands:
su
pacman -Syyu
{install optimus-switch-amd with commands from dglt}
still in su: htop
find “/usr/bin/lightdm” and SIGKILL it
it will automatically restart and viola, a desktop environment.
Now install as usual.
OpenCL does not detect any hardware except for the CPU (Tested on blender), but I expected 2 gpus and one cpu.
Cuda also does not work.

thats one way to do it i guess 
. there are easier ways but all that matters is that you got it installed.
i think you might need an opencl package for mesa for that to work on amdgpu, check the arch wiki. as for CUDA not working thats to be expected since your in amd-only mode, no nvidia means no cuda
otherwise, both modes work good?
edit: opencl-mesa i think is what you need for opencl to work on amd mode.
sudo pacman -S opencl-headers libclc ocl-icd opencl-mesa opencl-catalyst opencl-nvidia-418xx clinfo
On nvidia mode, blender CUDA detects the vega cpu and the 1660 as devices.
On amd mode, no devices are detected.
Also, I jsut noticed this but it seems the laptop is running rather hot when on amd mode without doing anything (just browsing atm, not rendering anything). The fan is almost constantly on whereas windows operates a lot quieter. Didn't see any abnormal values in htop though so I'm not sure what it could be.
There's some more weirdness: on nvidia mode, when rebooting the laptop gets stuck at
[ OK ] Closed LVM2 metadata daemon socket.
while still powering down.
Here's some more opencl/cuda stuff:
On nvidia, clinfo yields

Also, under nvidia mode the ryzen is now recognized as "ryzen with vega graphics" cuda device so that should be good. Note that the gtx 1660 as well as the ryzen+vega are only recognized as CUDA devices.
Under amd mode there are no detected opencl devices though, and no cuda devices.
But, there's also good news: both modes are stable so far and I haven't noticed any screen tearing or anything like that.

noooooooooo! not catalyst. make sure it didnt replace other packages when you installed it. if catalyst is a dependency for opencl-catalyst you got yourself some problems.
im on arch right now so opencl-catalyst, or anything catalyst is not available.
~ >>> pacman -Ss catalyst
~ >>>
if you dont use lvm you can disable it. i just checked and i have lvm2-monitor.service masked and the other related services disabled.
~ >>> sudo systemctl status lvm2-
lvm2-lvmetad.service lvm2-lvmpolld.service lvm2-monitor.service
lvm2-lvmetad.socket lvm2-lvmpolld.socket
though maybe next time it happens during shutdown, once you get booted back up post this output, its the journal log from the previous boot.
journalctl -b -1 -p4
amd mode wont have cuda available, im not sure why it doesnt list as an opencl device but i think you should start a new thread for that so others that are more familiar with amd hardware can assist you.
im not sure why this would be happening, install powertop , then from amd mode run sudo powertop and see whats using a lot of power, if you tab over to "Device stats" check to see if the nvdia gpu usage is at 100% or 0% .
What's the problem with catalyst?
I checked with pacman -Qi and it has no dependent packages, should I just remove it then?
Edit: I Rns'ed it, I read that it was outdated, and it served no real purpose anyway.

look at those battery savings, now you get 552+ hours of battery life. your welcome. 
jk, powertop just takes a bit to calculate that correctly. unless your battery is about the size of a fridge 
you need to maximize the terminal powertop is running in or scroll down until you see the nvidia and it's power usage. if it's powered down it should say 0%, if it's 100% then it's powered on but optimus-switch has a script included to fix that if it's needed.
the dinosaurs stopped making new versions of it when the meteor hit.
Hey, just noticed this: screen doesn’t come back on when closing then opening the laptop in nvidia mode. Don’t know about amd mode yet.
I see a white _ at the top left of the screen when reopening the laptop, but it doesn’t blink. Like it froze.
reproduce the problem, when you get to that black screen use ctrl+alt+f2 to get to a TTY. login with your regular user and run these
journalctl -b0 -p3 > wake-journal.log
cat /var/log/Xorg.0.log | grep -E "(EE)|(WW)|error|failed|Time" > wake-xorg.log
systemctl restart lightdm
does lightdm launch? desktop?
once your at the desktop, post these outputs.
cat wake-journal.log
cat wake-xorg.log
systemctl status lightdm
That’s the weird thing, when I enter the tty it just goes completely black. I’m gonna try to ssh into it now that I’m home and see what’s up
Edit: the issue does not occur when connected to the laptop via ssh
Edit2: issue seems to have fixed itself
oh yeah, that must of been the AI i added to optimus-switch. soon enough it might cook dinner and pour drinks too.
