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.

- | You know, for something that is supposed to be “fair” the law is not. I was looking at a case of a man clearly seen stealing the company product, by opening a side door and passing the products off to his accomplices. The value of the lost product was much more than his yearly salary. He obviously got fired and took the case for arbitration, arguing that it wasn't him. There are video cameras inside and outside and anyone with eyes can clearly identify the person. He won the case, because the company had no sign up, saying the door was under surveillance. That’s just stealing small in comparison to the EA’s of the gaming industry. | + | Vous savez, pour quelque chose qui est censé être « juste », |

- | Q: My old Dell Optiplex 3050 PC is not new by any stretch of the imagination and has been very happily running LXLE for the last five years, or so. It was snappy and had easy to use software pre-installed and was easy to configure. It also shipped with my favourite idler, Zaz. The only janky thing for me was Parole. The main reason I changed to Lubuntu was basically Appgrid stopped working and Librewolf told me ublock could not be “verified” and was disabled. Lubuntu doesn’t even have a store and has weird choices for software. It used to be LXDE, right? Can I make it into LXLE? | + | R : J'ai consulté le lien et il indique clairement la version 6.1.4.

- | A: Your question | + | **Q: My old Dell Optiplex 3050 PC is not new by any stretch of the imagination |
+ | A: Your question is a lot more involved than you think. While it is possible to add the LXDE desktop and software to match LXLE, you have to remember that the underlying tooling also differs. One could replace SDDM with LightDM etc, *if you have the time and patience. You also have to keep in mind that no-one is updating LXDE or fixing any bugs or vulnerabilities. Last time I checked, AppGrid was also dead, but I’m sure you can install another app store. The reason for Librewolf bombing is because the keys changed and it needs to have the old ones removed and then reinstalled. As for Zaz, it should* work on Lubuntu. I understand you like and prefer LXDE, but should you run into issues, there will be no help from zero developers.** | ||
- | Q: I’m running the latest version of Virtualbox on Ubuntu 24.04, but when the window is not fullscreen, it “drops” to the bottom of the screen. Then it seems to do this flashy thing, where if I type during a “flash”, the key strokes are not recognized. If I make it fullscreen, it goes away. If I’m on another virtual desktop I can see the icons for Virtualbox and the dot next to them “flashing” and it affects everything else. What can I do about it? I have tried VboxSVGA and VMSVGA, but it makes no difference. | + | Q : Mon vieux PC Dell Optiplex 3050 n'est pas neuf, loin de là ; il fonctionne parfaitement sous LXLE depuis environ cinq ans. C' |

- | A: If you change your host system login to X11 instead of Wayland, you should be good. As far as I know, Wayland cannot remember screen positions yet, (see LeoCAD blog) without lots of finagling, so it seems Oracle had not yet wrangled that one. | ||

And my work one is ctrl, win, alt with fn on the right side of the keyboard. Is there a way I can get them on the same page? Obviously the work one has Windows, but I have Ubuntu WSL.

- | A: OK as far as I know, there is no way to remap the Fn-key as it is hard wired. That said, you can faff with the others to get it to your liking. I’m going to assume Gnome, as you didn’t say what desktop you were using. Go to tweaks -> keyboard -> additional layout options -> Alt and Win behaviour, or -> switching to another layout option at the bottom. | + | R : Si lors de votre connexion au système hôte vous changez pour X11 au lieu de Wayland, tout devrait bien se passer.

+ | **Q: I have recently installed deb-get, but I’m yet to use it. I did the update and I was ready to install Skype, when it was announced that Skype would be ending in 3 months’ time. I was also thinking of getting Firefox instead of the Snap version, but I think that the Snap version may be safer as it is sandboxed. I tether my laptop via my phone for internet, as I live outside of town, so I don’t like to waste bandwidth as bandwidth = money. Can I see what’s on offer without internet connection? | ||

- | Q: I recently installed Minder on Ubuntu 24.04 Gnome edition, it is an elementary OS application. I set the application to be in dark mode in the settings, but nothing changed.

J’en utilise pas mal et je commence à m’inquiéter. J’envisage de migrer vers Linux Mint, mais ne risque-t-il pas de déborder ? |
+ | R : Je pense que oui, mais je dirais qu’il faudra attendre. Vous pouvez toujours conserver Ubuntu 24.04 un peu plus longtemps, car c’est une version LTS, et voir comment le vent tourne. Quant à Linux Mint, c’est une excellente distribution, | ||
