    I do in fact use unrefined, brown cane sugar, although I have not tried panela specifically.

    The one I use pretty much looks like this:

    It’s an organic fair trade brand, but I’d have to look up where it is imported from.

    As I said, I can’t imagine making it with any other kind of sugar any more. Sorghum seems like an interesting idea, might have to experiment with that.





  • An interrupt is an input that can be triggered to interrupt normal execution. It is used for e. g. hardware devices to signal the processor something has happened that requires timely processing, so that real-time behavior can be achieved (for variable definitions of real-time). Interrupts can also be triggered by software, and this explanation is a gross oversimplification, but that information is what is most likely relevant and interesting for your case at this point.

    The commands you posted will sort the interrupts and output the one with the highest count (via head -1), thereby determining the interrupt that gets triggered the most. It will then disable that interrupt via the user-space interface to the ACPI interrupts.

    One of the goals of ACPI is to provide a kind of general hardware abstraction without knowing the particular details about each and every hardware device. This is facilitated by offering (among other things), general purpose interrupts - GPEs. One of these GPEs is being triggered a lot, and the processing of that interrupt is what causes your CPU spikes.

    The changes you made will not persist after a reboot.

    Since this is handled by kworker, you could try and investigate further via the workqueue tools: https://github.com/torvalds/linux/tree/master/tools/workqueue

    In general, Linux will detect if excessive GPEs are generated (look for the term “GPE storm” in your kernel log) and stop handling the interrupts by switching to polling. If that happens, or if the interrupts are manually disabled, the system might not react to certain events in a timely manner. What that means for each particular case depends on what the interrupts are being responsible for - hard to tell without additional details.

    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.


  • 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.
