I don’t think java is using my gpu. How do I check or trouble shoot this?
tried nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Manjaro settings manager shows 450xx installed
It seems the nvidia driver is not installed/loaded or something. Please run inxi -Fza and sudo mhwd -li
Okay - not 100% sure what I’m looking for
inxi -Fza

It seems the nouvau driver is loaded? If you want the proprietary, then you need to blacklist nouveau.
Okay -
updated /etc/modprobe.d/mhwd-gpu.conf
with this line
blacklist nouveau
Is that the right way to do it? Getting ready to reboot now.
If nvidia fails will nouveau load or will I be at a black screen? I’ve had to reinstall my whole system before because I was messing with video drivers?
nouveau will not load. It’ll probably be a black screen, so you might want to install and start an ssh server to be on the safe side of things.
Dude I don’t know how to install or administer an ssh server . I’ll research it. For now I’m doing an external backup, and I’ll reboot. Fingers crossed.
Thank you for the help.
Well, if you’re not directly connected to the internet, it’s just:
sudo pacman -Syu openssh
sudo systemctl enable ssh
sudo systemctl start ssh
and you should be good to go. Anyway, I hope it’s gonna work out. The worst that can happen is a black screen with no TTY access, but then you can use the installation medium to fix the issue very simply.
Installation medium you mean an iso usb?
Yes, I mean that.
My backup finally finished. I rebooted. No blackscreen 
nvidia-smi returns driver info, nvidia-settings launches and shows new driver info. Seems to be working well.
Thanks for the help! I needed someone to walk me through that.
I am new to Linux entirely, and discovered that TD updated their TOS java? What does one need to enter into the konsole to get the appropriate java update to get this install to work?
Some recent updates to Thinkorswim require version 11. I discovered that jre8 was made default on my system despite having the version 11 components installed so I removed the 8 components and now it’s working normally with the java11-openjfx package. As for day-trading…can’t say I recommend it. Memes and short-squeeze plays can only last so long. But I will say that TOS’s interface is infinitely-better than TD Ameritrade’s dinosaur-looking main account page.
