- | In one of the companies I worked for, we had a very lax programmer. He would get up and leave for lunch, leaving everything as is. He would sit and work on the porch and people would be coming and going. No matter how many times I asked him to lock his computer at the minimum, it went in one ear and out the other. Explaining that he posed a security risk was water off a duck’s back. Usually someone else would bring the laptop inside when it was unattended. Since he was doing a job for ‘big pharma’, and he was the only programmer still left on the project who knew what was going on, even the boss was skittish about him leaving and this project failing. So my complaints went to the boss and his ‘stern talking to’ was actually begging. We did not want to hide his laptop as he would have an excuse as to why the project was not on time. One day he got up, got in his car, and went to go buy rotis. I was just about to bring the laptop inside, when I noticed he was signed into Facebook. An idea hit me, as his girlfriend had him on a short leash. I immediately changed his relationship status to single, signed him up for a couple of gay groups and put some cryptic comment and started ‘liking’ the worst stuff I could find. The first comment was from his girlfriend, a high maintenance, | + | **In one of the companies I worked for, we had a very lax programmer.

A: Usually the gaming laptops are developed for Windows only, unless it is from a Linux vendor like System 76. It takes time for Linux to catch up as the laptop was not made for it and there is no incentive for OEM’s to support Linux. Your options are to troll the forums and wait, or go back to Windows for a while. | A: Usually the gaming laptops are developed for Windows only, unless it is from a Linux vendor like System 76.

+ | Q : J’ai essayé d’exécuter Ubuntu sur mon portable de jeu, un Asus ROG, mais la mise en veille ne fonctionne pas et les ventilateurs tournent sans cesse au maximum. L’écran veut bien devenir vide, mais pas se rallumer. La résolution de l’écran n’est pas bonne et je n’arrive pas à la changer. Le portable est neuf et je ne veux pas le casser. Je débute sous Linux, car Windows 10 me faisait ch-er, en changeant le navigateur chaque fois qu’il faisait une mise à jour, mais Linux semble cassé ? | ||
+ | |||
+ | R : En règle générale, les portables de jeu sont développés uniquement pour Windows, à moins qu’ils viennent d’un vendeur Linux comme System76. Il faut du temps à Linux pour se mettre au niveau, car le portable n’a pas été construit pour et rien n’encourage les OEM pour prendre Linux en charge. Vos options sont de naviguer de forum en forum et attendre ou de retourner sous Windows pendant un certain temps. | ||

A: If you pin your panel icon to plank, clicking on it a few times should hide the top panel (and any other visible panel in XFCE). Now you can reclaim that space when your browser (or whatever) is full-screen. | A: If you pin your panel icon to plank, clicking on it a few times should hide the top panel (and any other visible panel in XFCE).
