Chromebook support

[Ceiyne]

Sorry, this is more of a question than an "issue". Do you happen to know if Splatpost works on the Linux environment that can be enabled on a Chromebook?

I don't have Linux set up on my Chromebook, and I'm not super familiar with Linux to begin with, so I figured I'd ask before I went through all of the configuration. If you don't know, I'll probably give it a try myself.

I'm not familiar with Chromebook, but I've googled that chromebook supports booting from USB. You can try to flash the image to a USB drive and reboot into it, which is preconfigured with a working linux desktop environment.

Please let me know if this works.

Thanks for getting back to me so fast. A Chromebook doesn't 'normally' support booting from USB; you have to basically wipe your system and disable all of the security features in order to do it. So, I would probably just go with the Linux environment available on Chromebooks and try to make that work.

I have been trying to get it to work on my Chromebook and I've made some progress but I'm at a point where I'm unable to figure out what to do next. After getting into Linux, there were a few things I needed to do to get SplatPlost going. I'll list them below for anyone else who might try this on a Chromebook, and also in case I did something wrong! Most of this has been trial and error with Google and StackExchange posts for me.

1. Needed to install pip sudo apt install python3-pip

2. Needed to install pkg-config sudo apt install pkg-config

3. Needed to install dbus stuff (info from https://stackoverflow.com/questions/61285415/no-package-dbus-1-found) sudo apt-get install libdbus-glib-1-dev libdbus-glib-1-2

4. Needed to install bluez sudo apt-get install bluez

After doing the above I was able to get to the point where starting the printer gives me this error. It seems bluetooth related, but I don't know enough about Linux to do much more here. I tried a few things that I found via Google which I'll list below the error.

$ sudo splatplot --order octotilt

During handling of the above exception, another exception occurred:

These are the additional commands I tried that didn't fix the error:

$ sudo systemctl enable bluetooth
Synchronizing state of bluetooth.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable bluetooth

$ sudo systemctl start bluetooth

sudo apt-get install bluetooth bluez bluez-tools rfkill -y
sudo service bluetooth start

I didn't get any errors from the above, but rfkill did not seem to be installed correctly as I would get things like this:

sudo rfkill list
rfkill: cannot open /dev/rfkill: No such file or directory
rfkill: cannot read /dev/rfkill: Bad file descriptor

sudo apt-get install blueman -y && blueman-manager The above command produced a lot of output and then hung on the last line "blueman-manager version 2.1.4 starting" for a while before popping up a window with an error saying that the connection to bluez failed.

By the way, if I've totally screwed something up with all the extra commands I ran, it's easy enough for me to delete the Linux environment and start over fresh.
