xubuntu51i | gracias, probaré por ahí | 00:01 |
xubuntu51i | En el canal en español, nadie me responde. Les cuento por si alguno de ustedes sabe y me dice. | 00:05 |
xubuntu51i | Tenemos una pc en el trabajo con xubuntu, es el server desde el cual acceden todas las computadoras con windows, a traves de XMing | 00:06 |
xubuntu51i | Todos los días a las 14 hs aparece un mensaje de actualización y la computadora se pone terriblemente lenta por unas dos horas. | 00:07 |
xubuntu51i | Mi intención es hacer que esto suceda, x ejemplo, a las 2 de la mañana. | 00:07 |
xubuntu51i | sólo tengo acceso al servidor por medio de línea de comandos, a través de ssh | 00:08 |
xubuntu51i | busqué información referente al tema, pero sólo encuentro como activar o desactivar las actualizaciones automaticas, o decidir si son diarias o semanales | 00:09 |
xubuntu51i | pero en ningun lugar encuentro la hora en que suceden las mismas. | 00:09 |
drleviathan | La pregunta es: ¿qué está causando que el servidor se desacelere? | 00:19 |
drleviathan | Puede ejecutar el comando "top" para mostrar dónde está ocurriendo la carga de la CPU. | 00:20 |
drleviathan | Además, examina los archivos de registro en /var/log podría dar algunas pistas | 00:22 |
nova | xubuntu51i, Parece que cron.daily ejecuta "actualizaciones desatendidas". La siguiente página explica cómo cambiar el tiempo de ejecución de cron.daily: | 00:24 |

nova | Sí, estoy de acuerdo con drl. Las actualizaciones automáticas no deberían reducir la velocidad durante 2 horas. | 00:25 |

xubuntu51i | investigaré con esta información que me pasaron, muchas muchas gracias a todos! | 01:38 |
tatai | 8:25 AM <tatai> Hello, I am a first time user of xubuntu and I am having a problem with vlc media player. Whenever I jump forward in vlc, the video becomes pixelated after being halted for a couple of seconds, though the audio runs just fine. After 7-10 seconds everything goes back to normal. OS- xubuntu 16.04 LTS, graphics card- nvidia GT650M. Googling it gave a link- | 03:11 |
tatai | https://askubuntu.com/questions/778933/vlc-pixelated-video-when-skipping?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa. Though a solution was not exactly offered. Is there any way to tweek it back to normal? | 03:11 |
nova | tatai that might just be a limitation of the codec, the way the frames are encoded | 05:29 |
nova | https://en.wikipedia.org/wiki/Video_compression_picture_types | 05:30 |
nova | tatai: ever so often in the video is a complete frame (i frame), then there are a number of p or b frames after that use that i frame as a referene point | 05:31 |
nova | when you skip, it would be ideal if you only snap to the nearest i frame | 05:32 |
tatai | Thank you for replying. | 05:32 |
nova | if you skip to a p or b frame you start off with limited information until the next i frame | 05:32 |
tatai | nova: thanks for replying. | 05:33 |
nova | youre welcome | 05:33 |
tatai | nova: If this is a problem with the encoding of the codec, then does it mean that it should happen irrespective of the video player? | 05:34 |
nova | unless another play snaps to the nearest i frame | 05:35 |
tatai | nova: I am asking because on mplayer that problem does not arise. | 05:35 |
nova | MPLayer and VLC | 05:36 |
nova | VLC appears be unable to skip/seek to key-frames. MPlayer on the other hand will use key-frames when you press the forward/backward buttons. These short-cuts will try to go ahead/backwards by 10 seconds but will use the nearest key-frame when doing so. This makes it extremely fast, especially if you have loaded the video from a RAM disk. | 05:36 |
nova | the source for that remark is here :https://blog.programster.org/fast-video-seeking | 05:36 |
tatai | Thanks a lot. Being a novice, such things are completely unfamiliar to me. I will be sure to read on it. | 05:37 |
nova | so the question is if its wanted or unwanted behavior...with vlc you have precisions down to a single frame, but that frame might not look right until the next complete frame occurs | 05:38 |
nova | basically think of an i frame as a complete picture, then imagne if the next several frams only store information about what has changed on the screen | 05:39 |
nova | if the camera is in a fixed position...then the codec only needs to store the parts that have moved or changed alot | 05:39 |
tatai | Ohhh, now I understand. | 05:39 |
tatai | You are exactly right. | 05:39 |
tatai | Usually the pixelated graphics does not get corrrected until there is a change in the camera angle. | 05:40 |
tatai | So the first frame in the new camera angle is serving as a reference point....right? | 05:41 |
tatai | nova: 11:09 AM <tatai> You are exactly right. | 05:42 |
nova | yes a drastic change in the scene will trigger a key or i frame early | 05:42 |
tatai | nova: 11:11 AM <tatai> So the first frame in the new camera angle is serving as a reference point....right? | 05:43 |
nova | they will ahppen at a set interval or when there is enough of a change in the scene | 05:43 |
nova | so perhaps every 60 frame or if there is a camera change | 05:43 |
tatai | Okay....now I understand this much much better. | 05:43 |
nova | you might notice different file formats behave a little differently | 05:44 |
tatai | Yes, that is also correct. | 05:44 |
nova | the questio is if theres a way to have vlc skip only to the nearest i frame | 05:44 |
tatai | .avi 's are a little sluggish on vlc on jumping | 05:45 |
emptyflask | (new xubuntu 18.04 installation) I'm wondering what's going on with ANSI colors in my terminal... I've got TERM=xterm-color, set force_color_prompt=yes, etc. https://imgur.com/a/WZe3B8e | 05:47 |
nova | oh...wow your prompt is not looking right | 05:48 |
nova | i did a fresh 18.04 install and did not need to change anythign to get colors in my terminal | 05:49 |
nova | you did this in .bashrc i assume | 05:50 |
emptyflask | well, tried in bash & zsh | 05:50 |
nova | did you not have a colored prompt to begin with? | 05:51 |
emptyflask | no, and I get the same results setting PS1 under root | 05:52 |
emptyflask | weirdly, `echo -e "\033[31;1;4mHello\033[0m"` works as expected | 05:53 |
nova | i dont know what zsh and ps1 are im afraid | 05:53 |
emptyflask | ah. PS1 being the environment variable that holds the prompt string | 05:53 |
nova | are you using xfce4-terminal? | 05:54 |
nova | well you seem to have colors its just your prompt is all mangled | 05:54 |
nova | mine just worked out of the box, heres my unmodified .bashrc https://pastebin.com/Hn6TW6zE | 05:56 |
nova | i use the stock terminal, and set the colors in the GUI | 05:56 |
nova | in the presets i dont see xterm-color i see only XTerm | 05:57 |
nova | emptyflask, https://pasteboard.co/Hoi8Hhj.png | 06:09 |
nova | it seems strange that ill of your folders show a forward slash at the end | 06:10 |
nova | all* | 06:10 |
emptyflask | hmm, I'm able to set a color prompt using `PS1="$(tput setaf 2)$ $(tput sgr0)"` | 06:10 |
tatai | Have a good day everyone. | 06:11 |
well_laid_lawn | PS1='\n\[\033[0;33m\]\D{%l:%M:%S %P}\n\[\033[01;34m\] [ \[\033[01;37m\]\W\[\033[01;34m\] ]\[\033[1;33m\]$\n\342\224\224\342\224\200\342\224\200\342\225\274\[\033[00m\] ' | 06:16 |
nova | yikes | 06:19 |
emptyflask | I've probably just screwed up my dotfiles by importing bash/zsh stuff from my macos config. setting force_color_prompt on a fresh user account works fine | 06:19 |
nova | but you still had to set it? | 06:19 |
emptyflask | yeah, it's commented out by default | 06:20 |
nova | i get a colored prompt with it commented out | 06:20 |
nova | i have this: #force_color_prompt=yes | 06:21 |
emptyflask | this is my usual monstrosity: PS1='\[\e]0;\w\a\]\n\[\e[0;32m\]\u@\h\[\033[0;30m\]:\[\e[1;32m\]\w\[\e[0m\] \[\033[1;30m\]$(get_git_prompt)\[\e[0m\]\n\$ ' | 06:22 |
emptyflask | (requires a get_git_prompt function) | 06:22 |

cr1mson_king | Hello. I'm trying to enable natural scrolling through Xfce's Mouse and Touchpad settings, but some apps ignore the change and keep scrolling with the default behavior. | 11:41 |
pmjdebru1jn | presumably non-GTK apps? | 11:41 |
* pmjdebru1jn is just guessing | 11:41 | |
cr1mson_king | pmjdebru1jn, for example, Thunar works with natural scrolling, but GNOME Software doesn't. | 11:42 |
