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 venu, premier servi. |

- | Q: Seriously not a fan of parted, is there another way I can resize my disks that is easier? | + | Tout le monde connaît l’histoire RAM « télécharger plus de RAM » et elle vous montre la crédulité des gens. Je me souviens même de mes déboires chez un ami quand il s’est procuré un « doubleur de RAM » pour son ordinateur sous Windows 95 et beaucoup de gens « autrefois » se sont fait escroquer par ces arnaques. Ce sont toutes des histoires qui nous font rire en pleine connaissance de cause. Cependant, il n’y a pas si longtemps que ça, j’avais une amie qui a obtenu une connexion par ADSL avant tous nos autres amis et elle ne se limitait pas dans ses téléchargements.

Q: Something very strange is going on, I set up a ping to 8.8.8.8 and reboot my router – I get connection issues – and there is a time it connects, receives between 2-5 packets back and then the ping fails again. My Xubuntu is still on version 20.04, but I had the same issue on 18.04. Then I need to disconnect the wifi with the network icon and connect again for it to work. If I don’t go through this ritual, I get connected to the router, but not the outside world. | Q: Something very strange is going on, I set up a ping to 8.8.8.8 and reboot my router – I get connection issues – and there is a time it connects, receives between 2-5 packets back and then the ping fails again.

Il s’agit en fait de droits : vous devez être dans un groupe avec des droits d’écriture vers ce fichier. Quand vous faites : ls – la – vous verrez les permissions sur la gauche, les r, w et x. Si vous n’êtes pas le propriétaire de ce fichier-là, vous devez être dans un groupe avec les droits de lecture et d’écriture vers ce fichier. |

Au démarrage, il active le 5 GHz auquel votre machine se connectera tout de suite, puis le logiciel dans le routeur désactivera la cadence de 5 GHz. Essayez d’activer le WiFi 5 GHz ou, s’il y a une raison pour laquelle vous utilisez le 2,4 GHz, obtenez un meilleur routeur ou un qui ne soit qu’à 2,4 GHz.

Q: I have Kubuntu on my laptop and my router is upstairs, when I go downstairs the signal is weak, so I installed another access point downstairs. The problem is that my Kubuntu does not automatically switch to the stronger signal when I am downstairs. I thought just making the SSID the same would have Kubuntu switching by itself.

The problem is that my Kubuntu does not automatically switch to the stronger signal when I am downstairs. I thought just making the SSID the same would have Kubuntu switching by itself. How do I do this? | ||
+ | A: In the router and AP WiFi settings, turn down the power output to say 40% and test. The issue is that the signal is not weak enough for Kubuntu to switch, so it stays connected. By default the power output is always like 100%. Play with those output values until it works. 100% power is probably overkill anyway.** | ||

- | Q: Is there any point to having snaps in Ubuntu? Please explain this to me as everything I read about it is negative, so why have it? | + | Q : Kubuntu est sur mon portable et mon routeur est à l’étage ; |
+ | R : Dans les réglages routeur et AP WiFi, baissez la puissance de sortie à, disons 40 % et testez-la. Le problème est que le signal n’est pas assez faible pour que Kubuntu change sa connexion et y reste connecté. Par défaut, la puissance de sortie reste toujours vers 100 %. Jouez avec ces valeurs jusqu’à ce que ça fonctionne. Une puissance de 100 % est probablement trop de toutes les façons. | ||
- | A: I did not want to answer this in Q&A as it is too long, but I think the answer will apply to a larger audience: People perceive snaps as bad, as they cannot control it, it will auto update your applications without asking. Linux is about control over your software after all. Secondly, for some programs it can be unnecessarily large – as it has to hold all the dependencies for that program. However, this is NOT always the case, for instance I have blender as a snap – it is roughly the same size and it does not install all those 100 other packages to my installation, | ||

+ | Q : Y a-t-il de vraies raisons d’avoir des snaps dans Ubuntu ? Je vous prie de bien vouloir me l’expliquer, | ||
+ | |||
+ | R : Je ne voulais pas répondre à ceci dans Q. ET R., car c’est trop long, mais je pense que la réponse intéressera un public plus vaste. Les gens perçoivent les snaps comme mauvais, car ils ne peuvent pas les contrôler, ils mettront vos applications à jour automatiquement sans demander votre accord. Après tout, dans Linux, il s’agit de pouvoir contrôler vos logiciels. Deuxièmement, | ||

+ | **Q: Don’t laugh, I am new to this stuff. I have normal Ubuntu 20.04 on my laptop. <image removed> This is the advert. So far I am happy to report that I have had no forced reboot updates or bluescreens. In learning about the Ubuntu ecosystem, I decided to install Jitsi. My issue is with the camera not displaying anything but a red haze. Audio works fine. I tried Skype instead, but I got the same problem, so I don’t think Jitsi is at fault. Can you help me? | ||
A: I don’t think Jitsi is to blame, or Ubuntu, for that matter. I suspect kids. That specific model in that picture has a red “privacy shield”. If you look around your webcam at the top of your screen, you will see the red circle, you need to slide that plastic back to reveal the lens underneath. | A: I don’t think Jitsi is to blame, or Ubuntu, for that matter.

Il me plaît tant que j’utilise Ubuntu Budgie actuellement. Avec l’arrivée proche d’Ubuntu 22.04, je redoute la réinstallation car j’oublie toujours QUELQUE CHOSE.

A: You CAN and you have a pretty good chance of it working too, unlike Windows – I would, however, see how it works first, as drivers are unpredictable. If not, do a fresh install on that machine and migrate your profile. | A: You CAN and you have a pretty good chance of it working too, unlike Windows – I would, however, see how it works first, as drivers are unpredictable.
