It depends on the knowledge, resources and level of desperation. I have participated in the making of disasters (everyone has a -r story) and in the fixing of other folks disasters. When you have no good backup (assigning backups to the FNG and not checking up on them is not a good plan) , and it re...

Yes it is, but work by command line too. In fact my focus is to execute same command(twinkle -c) that work by terminal. Do u think can i solve using longer "sleep" in crontab? I don't understand by default which user run o raspi. Because i need just to execute Twinkle, can u give mi other info abou...

Keeping in mind that it was not designed with battery powered applications in mind and is rather power hungry, you certainly can run one off of battery power. Once you define your desired run time and what peripherals you also want along for the ride it is fairly simple to figure out how big a batte...

I believe that is because Kodi does something cute with the frame buffer to improve performance and then the window system (typically X11) has to get restarted and/or take it over.

I'm more than likely to go for the Pi4 8GB model, what else would I need to buy apart from a keyboard, mouse wireless adapter, and HDMI lead which I already have, what be the best type of case to put the Pi4 in and anything else that I may need. Pi 4B uses a micro HDMI cable, which is not super pop...

Debian indeed does Toy Story characters, Ubuntu does descriptive animal, by alphabetical order. Personally I think it is easier to remember than redhat's numbering.

I suspect a simple list of BEGINNER commands is not going to change much from release to release. Presumably the OP is referring to the command line. of refer to something like https://www.howtogeek.com/412055/37-important-linux-commands-you-should-know/ The problem is that presumably the beginner ...

Was trying to figure out if you could build a pipeline with alien to do it. I suspect that you would just end up with a very broken system. You could define rpm as an alias to dpkg...

I have both and agree with James, the only task that annoyed the 4GB model was opening way too many browser windows. With the 8 GB model I can be even more entitled with my browsing and research habits. The 4GB is a huge step up from a 3B+. For general desktop stuff, going from 1 GB to 4 GB makes a ...

Lite == just the OS, no windowing system - suitable for building servers, or as a baseline for building your own setup, with a different window system, window manager, etc With Desktop == OS + Window Manager + some programs - suitable for use as a general desktop, has X11 + LXDE Window Manager + the...

It is the same as Raspbian-Buster, with the standard proviso that a newly built release will be slightly different than an older release that has been fully updated, for the 32 bit version. Likely the Lite verisons will be closer to identical, since there is less "stuff" in them. Obviously the 64 bi...

Odd, it should not do that. Normal behaviour is to default to whatever the last selected Window Manager was. How did you build it? Starting from Raspbian Lite (now Raspberry Pi OS Lite) and adding MATE works as you would expect. Mate-tweak is a addon utility that allows you set set a bunch of Mate s...

Would it be presumptuous to post a summary of commands, in one place, that could be useful to other beginners as they are/were to me? I have prepared the list from the answers to my questions and requests for assistance. It seems this would be rather useful if this is something suitable to share in...

The biggest problem with this is what level are you aiming at? Do you try and explain the shell or the GUI, do you assume folks know Windows and are looking for a mapping of functionality? Beyond that there are tons of resources aimed at all levels from beginner to expert. As Dougie mentioned, many ...

I've been having some issues with my raspberry pi 3, and somehow ended up running: sudo rm * In the directory /usr/bin Now that I have done that and try updating using: Classic example of why you should avoid using sudo. sudo and "rm *" should ring alarm bells! If you desperately need to run "sudo ...

With a fan you do not need the heatsinks. I am a big fan of the Pimoroni Fan Shim. Honestly with a open style case the fan (which is temperature controlled) runs very infrequently (comes on at 65, shuts off at 55) unless I am watching Netflix. One concern with cheap heatsink kits, the double sided t...

"uname" is a Linux command. If the makefile is not working, your build environment is not setup correctly. This would be easier if you were trying to do it on a x86 PC running Linux, but is possible on a Windows machine with the right toolchain setup. If you do not understand the suggestions in the ...

A couple of obvious questions, did it boot normally before you put it in the case? Did it boot normally before you installed the Argon script? If the answer is yes to either of those, I suggest to start there. It certainly should not take that long to boot. Potentially the script is doing something ...

Easiest is just renaming user pi to whatever you want, via "usermod" command. The trick is to be running at the console. Assuming nothing else is running with your username other then the shell on the console - no X session, no ssh login, etc, the following works: exec sudo -s cd / usermod -l newnam...

I suspect that it depends on where you live. When we commission new equipment in the plant we have to get it certified as to its compliance. Given that most of the equipment I care about is sourced from Germany, it tends to have German power setups. Said equipment is UL/CSA certified. In some cases ...

Fortunately, with us being users and not manufacturers, we're not required to seek regulatory approval. Change "not required to seek regulatory approval" to "not able to seek..." Beyond that, I suspect that messing about with WiFi is forboten in most parts of the world, especially if you are muckin...

Think what you need to have available to successfully run chromium (OS up, networking up, windowing system up with a DISPLAY defined, potentially internet connection depending on what page you are trying to display). I suspect that you do not have all of these "resources" available when @reboot runs...

Note: I think (but am not certain, that is why I say "think") that fonts are looked up via a PATH sort of mechanism that, like the executable PATH mechanism, doesn't look in the current directory by default. Unikely, there's no font path related environment variable set in any shell I'm using. I su...

Other than I think you have a bunch of typos in your "1" and "2"s which makes your question slightly confusing, you should be able to specify the display # when you initiate the VNC connection. The exact syntax will vary but it will be something like: vncviewer [options] [host][:display#] You may ha...
