I am on my 4th personal TUXEDO laptop, never had any issues. I actually started giving them to the devs at my company, no complaints so far.

They don’t offer my choice of OS, and I wouldn’t use a preinstalled OS anyway, so I can’t comment on that.

Generally all correct, here is a resource with a lot of in-depth information and additional links:

It’s not true that precision measurements are impossible with low value resistors, a lot of measurement equipment works exactly like that - it might just be more expensive than what the manufacturer is willing to budget for.

Tuxedo also offers products with an aluminum body, and while they do import the hardware from China, you get the local service and warranty guarantees any company in the EU must provide, so that’s fine by me.

Also, honest question: what do you think a unique laptop is, in particular when buying from a mass consumer brand like Lenovo? I really can’t figure out what that’s supposed to mean.

You can be angry about both things, the world isn’t black and white. Leave the fucking stones alone and blow up corporate headquarters for all I care.

lspci will read the vendor and device id via PCI and use that to determine what the device is. You might want to make the output a bit more digestable / useful via lspci -s 03:00.0 -k -nn, but I’d assume the ids that match an 2070 will show up.

Could you please take the card out and provide us with a few pictures from different angles, maybe getting a good look at the actual chips?

I’d like to rule that out before chasing rabbits here.

Also, you could always run nvidia-settings, which will show information about an NVIDIA card using a different access method.

I’d still like to see the pictures of the card though ;)

Oh, that makes everything a lot easier. The majority of the relevant settings will be in your home folder then, i. e. in the ${HOME}./.config folder, while some might also be in ${HOME}/.local/share etc.

You probably want to backup the whole home folder anyway, so that would pickup most of your settings. In order to make that work on a different system, you would have to install all applications you were using on the tablet as well. Luckily, software installation in Linux is pretty easy, so you can export a list of installed applications from the Surface and then re-install them on your target system before migrating your home folder. The software list should become part of your backup. See e. g. https://unix.stackexchange.com/questions/82880/how-to-replicate-installed-package-selection-from-one-fedora-instance-to-another for an idea of how to perform this.

I have used this approach in the past and it will get you 95% there. There might be some global system settings that you’d like to also transfer to your new system, but you can add those as you discover you miss them on the target system.

In general, no, this won’t work. In your case, you’re lucky since at least the Surface Go is using an x86 CPU, so it’s not completely out of the question, but transferring the image as-is to a completely different device typically does not work without modification.

Simple example: your target device might not refer to existing hardware (let’s say a storage medium) in the same manner as your old device, so the existing references in your cloned image won’t work. There are other issues of course, e. g. missing drivers for different hardware present on the target device.

It’s possible to modify the image so it would boot, but given the Surface runs Windows, that’s going to be a chore. I’d consider this an interesting project if bored on a slow weekend, but I’d most likely just do a filesystem backup of relevant data and call it a day.

Honestly, that just seems like you’re treating dd as some kind of arcanum. dd works just fine and I’ve been doing 1:1, full system backups for decades with it, no issues. Honorary mention for ddrescue / dd_rescue for recovery options, i. e. re-trying bad sector reads etc.

In fact, when Clonezilla doesn’t know your filesystem, it will simply employ dd to copy the data sector by sector.

I’d argue that Clonezilla (due to its use of partclone) is actually a less complete form of backup, since it will only copy used blocks, you don’t really end up with a clone of your devices, just a copy of what partclone believes to be your data. Don’t get me wrong, that is fine in most use cases, but there are some cases where this doesn’t cut it, e. g. wanting to backup / restore a storage device from a PLC where the vendor had the glorious idea to store licensing data in unused sectors, or when you want to create a forensic disk image, might want it look into d3dd then, although it absolutely works using regular old dd as well, d3dd just adds some amenities.

All I want to say is: dd is an absolutely reliable tool and can be a one stop solution for device backups. Also, I have absolutely no quarrels with Clonezilla, if it fits what you’re trying to do and it works, great.

I looked at eggy wets and it immediately stood out. It’s the only real band name deserving amy attention.

The best way would in fact be testing it with an electronic load that applies a precise and well known load to the battery and integrates capacity until a matching shutoff condition is reached.

However, the majority of people do not happen to have access to such an instrument, so I’d say your suggestion is a close approximation of the best way, which could be augmented by adding simple measurements, which can be done by most people at home for a reasonable, quantifiable judgment.

Just for the sake of completeness:

It’s useful to be able to do this without additional tools (and there are more applications for the general command setup discussed in the video), but in practice, ease of use and performance often make a difference.

Your USB ethernet adapter is down according to this output.

In case Ubuntu server comes with e. g. dhclient installed, you should be able to get a working network connection by ensuring a cable is properly plugged into your USB ethernet adapter and running

sudo dhclient -v enx949aa9857457

You might want to post the output of that command here. Alternatively, configure the USB adapter using one of the management tools mentioned in this thread already.

As a general rule, maybe don’t use shorthand terms you invented in posts that are supposed to provide information to the people trying to help you, just so you don’t confuse them any further.

Slight nitpick: Brymen handheld meters often have better specs in the handheld market, in particular when you are looking at a fixed price point.

You see a lot of Fluke meters around due to service agreement, as well as government and military contracts.

Don’t get me wrong, meters are fine, but there is no reason to spend that kinda money at home, unless the service manual of your washing machine explicitly states all measurements are to be done by a Fluke meter.

They do make managed switches, but just to be completely clear, my comment was mostly hyperbole. I just found the general combination of security - mindedness and cheap Chinese hardware curious / amusing.

I was wondering… that tp-link probably negates anything remotely resembling security on its own. But yeah, you can update some of these noname boxes easily, others, not so much.

I have dealt with (in a professional capacity) Chinese manufacturers that are under the impression they do not have to provide a working build tree for the kernel, let alone firmware, so its a gamble if you’re not talking to a major Chinese name brand. Mind you, I was ordering hundreds of those boxes, so there was some leverage.

I can second that. We had some really good experiences with ClickHouse and its performance. If it fits the bill, it’s a very nice piece of software.
