Same here. I have three models of Zebra printers and they were all pretty much plug and play with Linux.

+1 to this. Lots of talk in this thread about drivers, but the only driver involved here is the Bluetooth driver. Half of the point of Bluetooth is that peripherals don’t need their own drivers, they just provide various profiles which are standardized so the Bluetooth service can consume those profiles from any device.

Not an expert in this area but I believe the implementation of most of those profiles is user space, so the proper place to be debugging is the Bluetooth service or in pulsesudio. So start your Bluetooth service logs they might give you some idea as to what is going on. Try to get a list of what profiles are supported by your OS and what profiles are supported by the device, maybe the device only supports some newer lossless profile that hasn’t been implemented in Linux yet.

Slows down then freezes sure sounds like an out of memory situation, so to add to yours here they might actually want less swap. Sometimes you would rather hit the oom killer sooner instead of waiting on swap to fill.

Ideally login via SSH from another machine to figure out what is using the memory (hopefully the system is responsive enough for SSH), and if it is your critical programs causing the problem then you should consider a memory upgrade.

In any KDE app you can connect with SFTP in the open file dialog. Just type sftp://user@server/path and you can browse/open/edit files the remote server. ssh keys+agent make things a lot easier here obviously.

I believe so. The package descriptions for most of the ZFS packages in Ubuntu mention OpenZFS, so it certainly appears that way.

You can still create pools that are compatible with Oracle Solaris, you just have to set the pool version to 28 or older when you create it and obviously don’t update it. That will prevent you from using any of the newer features that have been added since the fork.

Well worse than that, Oracle closed sourced ZFS, so OpenZFS was forced to become a fork, and they are no longer compatible with each other.

As for GPL the CDDL license that ZFS uses made sure that code contributions attribute copyright to the project owners, which means they can change the license as they please without having to track down contributors.

You would think with their investments in Oracle Linux and btrfs they would welcome that license change, but apparently they need excuses to keep putting money into Solaris, and their Oracle ZFS appliances instead.
