Ceci est une ancienne révision du document !


Welcome back to another edition of Questions and Answers! In this section we will endeavour to answer your Ubuntu questions. Be sure to add details of the version of your operating system and your hardware. I will try to remove any personally identifiable strings from questions, but it is best not to include things like serial numbers, UUIDs, or IP addresses. If your question does not appear immediately, it is just because there is such a lot, and I do them, first-come-first-served.

Bienvenue de retour dans un nouvel épisode de Q. ET R. ! Dans cette rubrique, nous essayerons de répondre à vos questions sur Ubuntu. Assurez-vous d’ajouter les détails de la version de votre système d’exploitation et de votre matériel. J’essaierai d’enlever de vos questions toutes chaînes qui pourraient vous identifier personnellement, mais il vaut mieux ne pas inclure des choses comme des numéros de série, des UUID ou des adresses IP. Si votre question n’apparaît pas tout de suite, ce n’est que parce qu’il y en a beaucoup et que je les traite sur la base de premier arrivé, premier servi.

I was looking at games to review on Steam, when I came across one that seemed interesting. I had a look at the system requirements, Ubuntu 12.04, and lo and behold, the processor requirement was “potato+”, I kid you not! That brought me to thinking. You see modern CPUs are a lot faster than those of fifteen or twenty years ago, and hard drives vs solid state drives offer an even bigger gap. I’m not even mentioning memory. So why is it that some things just do not get better? What gets added to modern operating systems that make them so slow? Some people argue that it is systemd, others say it is kernel bloat, etcetera. I say, these limitations are artificially inserted. You see, some of these games play just as well on Ubuntu 6.06 as they do on 22.04. These type of games are usually written by an Indie team or someone passionate. When it is by a company, it needs to be out the door, yesterday, so they can fire all the programmers and reap the profits. So they use frameworks that are out of date as soon as the game hits the streets. This is precisely what you see with operating systems too. Microsoft and Apple. I mean that is why Linux is growing in popularity. The mainstream media always under reports Linux usage or adoption, (remember how Microsoft begged people to write to congress about “stifling innovation” during their antitrust allegations?) Anyway, modern Linux still power my old machines, my pre-core 2 CPU PC runs Bodhi Linux just fine. Probably a “potato -” processor compared to my new PC. Probably won’t even boot Windows 11 in under five minutes. You know what? I still use it to write on, I surf the interwebs and listen to audiobooks on, thanks to Linux.

Je regardais des jeux sur Steam pour en faire la critique, quand j’en ai trouvé un qui semblait intéressant. J’ai regardé les exigences système, Ubuntu 12.04, et voilà que le processeur devait être « patate+ », que l’eut cru ! J’ai commencé alors à réfléchir. Vous voyez des CPU qui sont beaucoup plus rapides que ceux d’il y a 15 ou 20 ans et les disques durs versus les SSD offrent un écart encore plus grand. Je ne parle même pas de la mémoire. Alors, qu’est-ce qui fait que certaines choses ne s’améliorent tout simplement pas ? Qu’est qui est ajouté aux systèmes d’exploitation modernes qui les rend si lents ? Quelques personnes blâment systemd, d’autres disent qu’il s’agit du gonflement du noyau, etc. Moi, je dis que ces limitations sont insérées de façon artificielle. Voyez-vous, certains de ces jeux se jouent tout aussi bien sur Ubuntu 6.06 que sur la 22.04. Ces genre des jeux sont généralement écrits par une équipe indépendante ou par quelqu’un de passionné. Quand c’est écrit par une société, il doit être publié la veille, afin qu’elle puisse licencier tous les programmeurs et réupérer les profits. Ils utilisent donc des cadres qui sont périmés dès que le jeu devient disponible. C’est exactement cela que vous voyez avec les systèmes d’exploitation aussi. Microsoft et Apple. C’est pour cela que la popularité de Linux est grandissante. Les principaux média diminuent toujours les chiffres d’usage ou d’adoption de Linux. (Vous vous souvenez de comment Microsoft a insisté qu’il fallait écrire au Congrès au sujet de « l’innovation étouffante » pendant leurs allégations antitrust?) Quoi qu’il en soit, le Linux moderne alimente toujours mes vieilles machines : mon PC avec un processeur pré double cœur utilise Bodhi Linux sans problème. Probablement un processeur « patate - » par rapport à mon nouveau PC. Celui-ci ne peut probablement même pas démarrer Windows 11 en moins de cinq minutes. Vous savez quoi ? Je l’utilise encore pour écrire des choses, je surfe les interWebs et écoute des audio-livres dessus, tout cela grâce à Linux.

Q: I can only see 3 processes when I run ps ax which is 1,10,12. On my personal laptop I can see a lot. What does that mean?

A: It means that the session you are in has a restricted namespace. My guess is probably a container rather than a full OS? Are you doing a CTF? Read up on cgroups and namespaces.

Q: I am trying to run https://tobyfox.itch.io/deltarune on plain Ubuntu 22.04, but it is not working. It worked on Ubuntu Mint, but that is not working with my new Nvidia 3060 any more. So now I am in a bind. My error is this — “”libssl.so.1.1: cannot open shared object file: No such file or directory”” and I don’t know where to start fixing this.

A: OK, I had a look and it seems DeltaRune has no Linux build? As it is GameMaker, I assume this is an unofficial build, as GameMaker can make Linux builds. This may help: Go to /usr/lib and make a symlink called libssl.so.1.1 to the libssl.so that you have: cd /usr/lib

sudo ln -s libssl.so libssl.so.1.1

or you can try this: https://stackoverflow.com/questions/72133316/libssl-so-1-1-cannot-open-shared-object-file-no-such-file-or-directory

Q: On Ubuntu Gnome, in the software centre, it says that the snap store must be updated, but when I do it, I get an error. Null, cannot refresh snap store, has running apps. When are they going to fix this? Snap refresh says all apps are up to date. Updaters should update, it should not be broken. I hate having to go into the terminal and type latin.

A: One cannot use a screwdriver to fix itself. You need another. If you close the Snap store, it does not close 100%, sort of like Apple apps. It is like Windows TSR so you need to go into the terminal and tell it to close completely, pkill snap-store does that for you. Now you run;

sudo snap refresh

which is the other screwdriver to fix the first. If you do not like snaps at all consider Linux Lite or Linux Mint.

Q: I have Windows on my laptop, I have downloaded an ISO to USB and installed Ubuntu on my laptop. Boot option not giving me Ubuntu. BIOS is password locked. How can I get Ubuntu now? I have a new 256gb SSD, but still I cannot boot.

A: Bioses are strange beasts, you will need to unlock it somehow, to turn off the Windows only settings. You can try some common passwords, but if you do not come right, you may have to get that BIOS chip flashed anew. It goes beyond our simple Q&A.

Q: On Kubuntu 22.04, I closed my laptop lid after an evening of setting it up just the way I like it. In the morning I opened it to find it no longer accepts my password. If I preview the password, it shows the right one, but it will not unlock? It’s been 2 days now and I don’t know what to do.

A: I recall seeing something about KDE themes breaking things, but I did not pay attention. My suggestion is to shut it down or try to log into another TTY. You should see from there if you are using the correct password or something is damaged. Remember you can always boot with a live boot image and change the password. You can also always: touch fsck and reboot. Password reset articles are all over the internet.

Q: I am having an issue running my VPN with Ubuntu. I open the terminal and type – rather up arrow to the string– <removed> every time I start or open my laptop, can I not run this on a desktop icon? Ubuntu 22.04, N5105 3ghz, 4gb RAM 256GB SSD.

A: You do know that there is a graphical setting for VPN in Ubuntu 22.04? You just need to add it in the settings first, then it will show up every time you click the cluster on the top right. You can turn it on and off from there. The way you are doing it is outdated. (for quite some time actually)

Q: We use some horrible thing at work to stop people from surfing illegal things and when I am at home I still get “site blocked” for Reddit, even though I am on my own wifi. Can’t Ubuntu overcome this?

A: my first answer to that is usually, use your own laptop for private things, however if it is your own device, I suggest you hardcode your DNS entries to something like GoogleDNS, 8.8.8.8 or Cloudflare 1.1.1.1 or even quad 9. You can also use Firefox’s secure/encrypted DNS.

Q: Is Ubuntu becoming Windows? Every time I run an update I have to reboot or I get “gah, your tab just crashed” in my browser.

A: That is not Ubuntu’s fault, but Firefox. If you wish to continue working in your browser, when you update, simply deselect Firefox and update everything else. Once you are done with what you were doing, update Firefox and reboot.

Q: I got a mini PC for Christmas and I installed Ubuntu on it. It seems to work for the most part. The terminal is the problem. I type then like a second later, the letters appear. It is almost like it is checking what I typed before typing it in the terminal. I am using X11 and not Wayland, so it’s not that. I’m kind of stumped?

A: I had a quick poke around and it seems to be a mutter issue. You can add this PPA for now until the issue is sorted. Type:

sudo add-apt-repository ppa:vanvugt/mutter

sudo apt update

sudo apt upgrade

reboot.

Q: I recently updated my firmware, now there is a Dell logo with ‘secured by dell securebios’ or some such nonsense written on it. This now shows during boot and I want it gone. I prefer not to have any writing or extra logos in my Ubuntu boot.

A: You may be able to turn it off in the BIOS itself, but if it is showing up during boot as well, I found this that may help: https://askubuntu.com/questions/1238754/want-to-remove-oem-logo-during-boot-in-ubuntu-20-04

Q: I have now lost my Skype account that I have had for many years, due to my ISP changes in the last few years. You see I created the account with my very first ISP e-mail account. That is history like 3 ISP’s ago at least. Microsoft will not let me recover it without that account. Is there a Linux alternative to Skype that I can get my whole family on? Please do not say Teams.

A: There is always Jami. I almost pointed you to Jitsi. Jami is easy to install and operate and works on almost any platform. If you use Brave browser, I think they recently launched Brave talk? I’m sure even Linphone may work for you.

Q: I have Ubuntu 23.10 installed and I noticed something different to my Ubuntu 22.04 install, in the realm of LibreOffice. On 22.04 I can double click a word, and it will highlight, allowing me to type over it. On 23.10, if I double click there, only my curser’s I-bar jumps around. If I triple click, it jumps to the end of the paragraph. Can I install the old version like 22.04 to fix it?

A: In LibreOffice, you have different types of selection. I suspect you clicked on block selection, by accident. It happens. You need to change it back to standard selection, which is double click = word, triple click = sentence. The easiest I know is to look left of the magnifier and page layout in the status bar at the bottom. It may look like your cursor’s I bar or the symbol for space.

Q: How does one get those ligatures in plain bash? I want the Ubuntu icon. I see tutorials for zsh, but I prefer just plain bash. Just explain it like you are talking to a child please, I’m just starting out with Ubuntu.

A: I’m not 100% on that, but I know if you download nerdfonts (https://www.nerdfonts.com), you can change your terminal default font to one of those, it is under ‘appearance’ and they contain what you are looking for. How you type them etcetera, is something you will need to read up on, sorry, I have never used them.
