- | Q Is my HP laptop compatible with Ubuntu? (Link to specs provided.) | + | |
- | A There is a good chance that your laptop is 100% compatible with Ubuntu. The most likely source of problems is the Wi-Fi adapter, and companies generally don't publish exact details of the Wi-Fi adapter, because they often change suppliers without rebadging the laptop. | + | A See this: https:// |

- | [ 2.937043] ACPI PCC probe failed. | + | What you have is two RAID arrays of four drives each; if you want a single array, you need to set that up from the controller card. With eight drives, you should consider RAID6, to protect against a second drive failing before you can replace a single |

- | Q I installed lubuntu on an Acer Aspire 3630 but I can't find how to install the SIS video drivers. | + | R (Merci à darkod sur le forums Ubuntu.) Si vous utilisez la carte contrôleur raid du serveur et configurez une ou plusieurs matrices RAID5, le système d'exploitation les voit comme des disques tout court. Il NE FAUT PAS les « raider » davantage avec des logiciels RAID. |
- | A There are no SIS video drivers. | + | Vous avez deux matrices RAID de quatre disques chacune ; si vous voulez une seule matrice, vous devez la paramétrer à partir de la carte contrôleur. Avec huit disques, vous devez réfléchir à RAID6 pour vous protéger contre la mort d'un deuxième disque avant de pouvoir remplacer un seul disque défaillant. |

- | Good Things Come to Those Who Wait | + | |
- | + | ||
- | More than two years ago, I decided to see if I could use USB 3.0 with my "high performance" | + | |
- | + | ||
- | I bought a card which plugged into the computer and provided a single USB 3.0 port. Along with it, I bought a 32 GB, USB 3.0 flash drive. The result was not what I had hoped for. | + | |
- | + | ||
- | I could plug a USB 2.0 flash drive into the USB 3.0 port, and it worked just fine, at USB 2.0 speeds. | + | |
- | + | ||
- | I could plug the USB 3.0 flash drive into a USB 2.0 port, and it seemed to operate faster than a USB 2.0 flash drive, but not dramatically so. | + | |
- | + | ||
- | When I plugged the USB 3.0 flash drive into the USB 3.0 port, it simply didn't work. | + | |
- | + | ||
- | OK, I can handle this. If you never have an experiment which fails, you aren't trying enough experiments. | + | |
- | + | ||
- | Come forward to 2016, and Xubuntu 15.10 running on the same hardware. It works! The USB 3.0 flash drive is almost as fast as an internal hard drive, which is going to make backups a lot faster. | + | |
- | + | ||
- | Similar sequences occur with a lot of new hardware. Nvidia introduces a new video card, and it's nothing but grief for the first six months. Two years later, it just works. | + | |
- | + | ||
- | The corollary of this story: if you buy a computer with the latest and greatest hardware, you need to try the latest version of Linux on it. In some cases, you will get the best results with a beta version of Ubuntu! But first, try the latest released version. | + | |

- | Tout vient à point à qui sait attendre | + | J'ai également ajouté une carte USB 3 avec un seul port qui fonctionne très bien maintenant (cf. la rubrique du mois dernier). |
- | Il y a plus de deux ans, j'ai décidé de voir si je pouvais utiliser USB 3.0 sur mon ordinateur de bureau «haute performance». | + | **The AMD Phenom II dual-core CPU at 3.1 GHz, and the 640 GB Western Digital Black hard drive, still meet my needs. If I spent two grand, I could probably build a system which would be three or four times as fast, but that wouldn't make much difference to me. When I power up, I usually go and make myself a coffee, so the faster boot time would be wasted. I do a little video editing, so the speed would help there, but it's not crucial. Perhaps my lack of desire for a new system illustrates the sad state of the PC industry. |

- | Je pouvais brancher une clé USB 2.0 sur le port 3.0, et ça marchait bien à la vitesse de l'USB 2.0. | + | Software has progressed slowly. When I set up the computer, it was dual-booting the trial version of Windows 7 and Ubuntu 9.04. Now, I have Linux Mint 13 (based on Ubuntu 12.04) and Xubuntu 15.10. In between, there were a lot of versions which were not stable on my hardware, including 14.04. I hope that I will be able to upgrade to 16.04 and stay there for a while. I know a lot of work has gone into the kernel and the distros, but the only improvement which has helped me is being able to plug in my phone and see it as a flash drive.** |
- | Je pouvais brancher la clé USB 3.0 sur un port 2.0, et il semblait aller plus vite que la clé USB 2.0, mais pas tant que ça. | + | L'AMD Phenom II CPU à double cœurs et à 3,1 GHz, ainsi que le disque dur Western Digital Black de 640 Go, répondent toujours à mes besoins. Si je dépensais |

For computer hardware and software, I can't think of a single thing which I would describe as, "I want to buy..."** |
