- | I worked for an automation company back in the day. My direct boss, the IT Director, was unhappy with his laptop. To fill in the background, let me state that he would test ALL our software on this laptop. Needless to say, Windows needed a registry clean and temp file clean like it is nobody’s business. (He also used it everywhere crappy, so the exhaust ports were probably all blocked inside.) I would venture to say that, daily, he would install and uninstall at least two programs downloaded from the internet, sometimes sketchy as all heck. However, he was very impatient and had the opinion that everything should just work and it was Microsoft’s baby to see that it did, as he paid good money for the OS. He could never set aside an hour or two just so I could get into the guts of the thing and see if I could rectify the problem. If the problem wasn’t solved in the first five minutes, he would chase you away and say he would do it himself. This culminated in him taking the laptop after a few weeks and shoving it behind a forklift and simply driving over it, claiming a new one from the insurance company. He loudly blamed the laptop manufacturer, | + | 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 venu, premier servi. |

Il va sans dire que Windows avait besoin d’un registre propre et d’un fichier temporaire propre, ce qui était presque impossible.

J’ai essayé de faire des recherches avec Google, mais je ne sais pas quels mots clés il faudrait entrer. Rien de ce que j’ai essayé (à partir des endroits comme stack-overflow) a fonctionné pour moi.

Q: I’m a bit clueless, so please bear with me. I installed my P2P apps in Ubuntu, set my network port to 119, and set my method to encrypt only and also my IP v6 to off. Which is what I used to do on Windows 7. Nothing else. I did not even change the interface colors. Yet I cannot get it to work. I tried 3 different P2P programs and they all will not communicate with the outside world. My friend suggested that it is UFW I need to install to make it work, but I have no idea how to set it up for P2P networking. | Q: I’m a bit clueless, so please bear with me.

A: I am unsure what you want, but I suspect you are wondering why your fan is going bananas. Firstly, the laptop is charging when the USB-C plug is in, causing heat, as energy is converted from one range to another. Secondly, the GPU, yes, your laptop has one or you would not get a display, is working twice as hard for a second monitor and then extra because it is a wide screen. The laptop display needs to fill in only 1920x1080 pixels every second, whereas the external one needs to fill, say, 3840x2160 every second. Make sure the laptop is well ventilated off the table too, the height of the feet are usually “minimum” height. | A: I am unsure what you want, but I suspect you are wondering why your fan is going bananas.

It lasts a lot longer without the cooling pad, maybe 2 days, why would that be? | + | Q : Un dock Dell – K20A - est connecté via USB-C à mon portable sur lequel est branché un écran large via HDMI. Le ventilateur s’active beaucoup quand je travaille sur l’écran large, mais ne s’allume presque jamais quand j’utilise mon portable au lit. J’ai installé TLP, mais il n’y a aucune différence.

A: That probably has more to do with the BIOS setup than Ubuntu. Make sure that your BIOS USB settings are set NOT to provide power in suspend mode or power-off mode, something like that. I have a sneaky suspicion you have a cooling pad with fans that continue spinning when you close your laptop lid. Another option would be to simply unplug the cooling pad from the laptop when it sleeps. | A: That probably has more to do with the BIOS setup than Ubuntu.

A: My guess is that the issue is not Ubuntu, but old cabling that came across with Moses on the boat. Old cables are usually rated for only 10-100Mbit traffic. Try picking up some CAT5 cabling.
