len_1304Haohmaru,  do you have a colorimeter?00:02
Haohmarua what?00:02
len_1304a device that sticks to your monitor and measures the amount of rg and b00:03
Haohmaruugh00:03
Haohmaruokay, so that's not what i thought it is00:03
len_1304What are you looking for?00:04
Haohmarui need to fix the colors by eye00:04
Haohmarurgb curves or something00:04
Haohmaru(it's a CRT monitor)00:04
len_1304That is beyond my knowledge ...00:04
len_1304The type of monitor should not matter, a CRT changes faster, but the lcd ones change over time as well00:05
len_1304I think you are looking for the gamma settings for x00:06
Haohmaruwhere's that?00:06
len_1304Something like kgamma00:07
len_1304I am sure there is a way of doing it from the commandline too... using xrandr or something like that00:07
len_1304kgamma is the only one I can find off hand, just install it with synaptic00:09
len_1304It may pull in lots of kde libs though. be warned.00:09
Haohmarui'm so not familiar with anything, linux is too alient for me ;]00:10
Haohmaru* alien00:10
len_1304if you open a terminal you can view the (somewhat complex) man page for xrandr.00:11
len_1304 It does adjust gamma settings.00:11
len_1304something like xrandr --gamma red:green:blue00:12
len_1304where red green and blue are a number. I think 1 is no change and a fraction is less of that colour and anyting over 1 is more.00:13
Haohmaruyeah i can imagin, i wish there was a more visual way to set this00:15
len_1304There used to be... but I have not seen one for a long time00:15
len_1304xgama might be easier00:20
len_1304*xgamma00:20
len_1304It is still a command line tool, but it just does gamma, not all the stuff xrandr does.00:20
len_1304Strange, I installed kgamma... but I can't find it on the system00:25
len_1304It is probably an applet that runs only from the kde settings dialogue00:27
len_1304Yes kgamma can work :P  the command line to get it to work is:00:33
len_1304kcmshell4 kgamma00:33
len_1304But you have to install it first. It does have a gui for adjustments00:34
len_1304Haohmaru, ^^^00:34
Haohmaruit said i need to install kde-runtime00:40
Haohmaru..and i think i did00:42
curtisjohnHey guys02:53
SuperRoachGood evening. I've just noticed my 12.10 ubuntu studio, apps  has lost their menu with the min/close icons. http://i.imgur.com/SCFC43t.png What can I use to restore it?10:15
Haohmaruhow do i configure the sound on Flash/Firefox.. got no sound on youtube videos15:15
holsteinHaohmaru: tha same as main ubuntu, it should just work15:15
holsteinHaohmaru: that is the only case in which you have no sounds?15:15
holsteinotherswise sound is good?15:15
Haohmarui managed to make Audacious play15:16
holsteinHaohmaru: so, audacious works? stand alone? or are you using JACK?15:16
Haohmarubut i had to adjust some stuff, cuz i have a built-in soundcard (which is crap) and a PCI soundcard also (that's what i need)15:16
Haohmaruyes, i think i chose this JACK thing15:16
holsteinHaohmaru: ?15:17
holsteinHaohmaru: confirm if you are using JACK or not.. try stopping JACK, and test audio with just pulse alone15:17
holsteinyou can restart the machine and just dont start JACK if you need15:17
Haohmaruyes, in Audacious i've selected JACK15:17
holsteinHaohmaru: so, you are likely running JACK then.. i'll just wait while you confirm that15:18
Haohmaruyup15:18
holsteinHaohmaru: also, consider *not* using JACK, if you dont need it15:18
Haohmarui changed Audiacious to PulseAudio - and it doesn't play at all15:18
holsteinHaohmaru: that would be the case, if JACK is running, and you havnet stopped it, or have no idea *if* jack is running, or how it got started15:19
Haohmaruwell, right after i installed ubuntustudio - didn't had any sound15:19
holsteinHaohmaru: do me a favor15:19
holsteinHaohmaru: reboot, and come *directly* here15:19
Haohmarualright15:20
holsteinHaohmaru: i can explain several scenarios where you wouldnt have sound, and specluate, and guess15:20
Haohmarushould i do something before rebooting?15:20
holsteinHaohmaru: no15:20
Haohmaruokay15:20
holsteinHaohmaru: you should specifically do *nothing* after rebooting15:20
holsteinjust come here15:20
Haohmaruk15:20
holsteindont start any application that might try and start JACK in the back ground15:20
* Haohmaru is here15:23
holsteinHaohmaru: ok.. open pavucontrol, and just leave that open15:23
holsteinHaohmaru: open whatever browser and test audio15:23
Haohmarupavucontrol - the sound icon or in a terminal?15:24
holstein!info pavucontrol15:24
ubottupavucontrol (source: pavucontrol): PulseAudio Volume Control. In component universe, is optional. Version 1.0-1 (quantal), package size 140 kB, installed size 953 kB15:24
Haohmarui guess in terminal15:25
holsteinHaohmaru: dont guess.. test and look and ask15:25
Haohmaruwell is this "pavcontrol" a command or is it the speaker icon on the taskbar?15:26
holsteinHaohmaru: "pulseaudio volume control" should be in your menu, assuming pavucontrol is installed.. pavucontrol from the terminal will start it15:26
Haohmarui haven't installed anything additional15:26
holsteinHaohmaru: open a terminal, and type "pavucontrol" and hit the enter key.15:26
Haohmaruokay, pretty much the same thing opens as when i click on the sound icon15:27
holsteinHaohmaru: so, now you know15:28
holsteinHaohmaru: leave that open, and also, its either *exactly* the same, or not.. not "pretty much"15:28
Haohmaruit's the same15:28
holsteinflip through there and make sure all looks aw you would expect15:28
holsteinopen a web browser and test audio15:28
Haohmaruk15:29
Haohmaruah, it works now15:29
holsteinHaohmaru: ok.. so heres the issue.. fact: sounds works.. speculation: you are clicking something like ardour in the menu that launches JACK and that is breaking your current "working" audio15:30
holsteinHaohmaru: also, you did some "tweaking" that i would need you to elaborate about15:30
zequenceHaohmaru: you can choose which audio device is default, by clicking the green "v" icon in outputs. It says "fallback" or something like that15:30
Haohmaruyes, that's what i was tweaking15:31
Haohmarutried to disable the built-in soundcard15:31
holsteinHaohmaru: i do that in hardware... bios, or blacklist15:31
zequenceHaohmaru: There's a bug in jack, that makes it crash sometimes, when trying to stop it. There's only one way to kill it, in a terminal: killall -9 jackdbus15:32
zequenceHaohmaru: jack is a pro audio server, which is not on by default15:33
zequenceHaohmaru: you can control jack with qjackctl15:33
zequenceHaohmaru: You need jack to most of the pro audio applications.15:33
zequenceHaohmaru: Here's a page I wrote about audio on Ubuntu Studio https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro/120415:34
Haohmaruahum15:35
Haohmarubtw, after the reboot, the gamma adjustments i did are lost15:35
Haohmaruxgamma iirc15:35
Haohmaruis there a way to make em permanent?15:35
zequenceHaohmaru: Maybe they were not saved anywhere? You could create a startup script for it15:36
Haohmaruautoexec.bat ;]15:36
zequenceHaohmaru: http://paste.ubuntu.com/5567905/15:37
zequenceMake a file like that. Make it executable (right-click, properties..)15:38
zequenceNot sure how auto start works for users in XFCE15:38
zequenceYou just place that file somehwere, and create a autostart for it, just like you would for any application15:38
zequenceHaohmaru: I'm guessing you were using a command line argument to adjust gamma, right?15:39
Haohmaruyeah15:40
zequenceHaohmaru: You could begin by making the script, then double click it, and choose run15:41
zequenceit needs to be executable, of course15:41
zequenceIf that works, you find out how to create a auto run15:42
zequenceIf no one here knows, try #xubuntu, or #xfce15:42
zequenceHaohmaru: Oh, my point was that you try it first, to see if it works or not15:42
zequenceHaohmaru: If you want help with the script, I can help you with it. Just let me know what kind of command you are passing15:43
Haohmaruokay, it works15:44
Haohmaruit's weird when files don't have extensions in their name ;]15:45
zequenceHaohmaru: In Linux, everything is a file.15:46
zequenceThe extension doesn't really tell you what it is15:47
holsteinthe extensions can be incorrect, or malicous in some scenarios15:47
zequenceBut, if it's executable, and it's a text file, that usually means it's a script. The first line tells what script interpreter to use. In this case, bash15:47
zequenceFor python, you'd do: #!/usr/bin/python15:48
zequenceIt's telling where the location of the starter is15:48
Haohmaruhm, funky ;]15:48
zequenceHaohmaru: Is there a xfce4-autostart-editor?15:48
zequenceTry in a terminal15:49
Haohmaruno such command15:49
zequenceHaohmaru: How about: xfce4-session-settings15:49
Haohmaruyeah, got this one15:50
zequenceShould be a tab called "Application Autostart"15:50
zequenceAdd your script there15:50
Haohmarudone15:51
Haohmaruthanks15:51
zequencenp15:51
Haohmaruso this JACK is used for more funky stuff?15:52
Haohmarucuz my soundcard is kinda funky15:52
zequenceIf you are doing any kind of recording, mixing or just playing soft synths, you'll need it15:53
Haohmaruit has MIDI and ASIO (at least on winXP with it's special drivers)15:53
zequenceASIO is Windows only.15:53
Haohmaruahum15:53
Haohmarui'm also gonna be interested in looking around thru those video editting apps, some day15:54
zequenceALSA is the core of PCI and USB audio. It doesn't support firewire15:54
Haohmarumy soundcard is PCI15:55
zequenceYou could run ALSA as an audio servers as well, but for the past years, Pulseaudio has been the desktop audio server on Ubuntu.15:55
Haohmarum-audio audiophile 249615:55
zequencePulseaudio uses ALSA drivers, and interfaces for devices15:55
zequenceJack also uses ALSA15:55
zequenceBut, jack can use other drivers too15:56
zequenceFor firewire devices, you'd use ffado drivers. In qjackctl you'd select "firewire" as the driver15:56
zequenceIt's the same thing15:56
zequenceSince you are using PCI, the only thing you will ever use is ALSA15:57
zequenceAll of the alsa drivers come in one package, so you never install them separately15:57
zequencePulseaudio is the desktop audio server, which is on by defaut15:57
zequencejack is a pro audio server, which on Ubuntu Studio, you need to start manually15:57
zequenceWhat you do is, you start jack first. then any application that uses jack15:58
zequenceqjackctl is a good tool for the jack beginner15:58
zequenceHaohmaru: Now, there may be a problem when you start jack. If pulseaudio is using the device you want jack to use, it may not let it go. This is a bug15:58
zequenceIf PA is using a different device, there will be no problem15:59
zequenceHaohmaru: There's also a PA(pulseaudio) module that can interface with jack. On Ubuntu Studio this is on by default. So, when you start jack using qjackctl, all desktop audio is routed to jack15:59
zequenceHaohmaru: You'll see this in qjackctl -> connect15:59
zequenceThat's about it16:00
Haohmaruso the main thing is ALSA16:00
zequenceHaohmaru: Yes, but you usually don't select ALSA in applications you use. Only if they don't support either jack, or pulseaudio16:01
Haohmaruahum16:01
Haohmarukinda got it now16:01
zequenceIt is possible to use ALSA as an audio server too16:01
zequenceBut, that is not done in Ubuntu Studio16:01
zequencePulseaudio has overtaken that role16:02
Haohmarui guess for midi i'd need to put the special drivers for the soundcard16:02
zequenceHaohmaru: No. midi is always on. you can see your midi devices in qjackctl -> connect -> alsa16:02
Haohmaruah, kewl16:02
Haohmarucuz the soundcard is no longer supported ;]16:02
zequenceThere are two types of midi. ALSA and JACK. ALSA is the most common, and it's always on16:02
zequenceHaohmaru: In Linux, there's no such thing as no longer supported16:03
zequenceIt's not the vendors who make the drivers, usually16:03
zequenceAnd even if they do, there is usually a free alternative16:03
Haohmarui mean that the company was bought by another company and they aren't gonna be supporting their old products/drivers anymore16:03
zequenceWell, in this case, they have nothing to do with the ALSA drivers anyway :)16:04
zequenceHaohmaru: qjackctl -> connect has three tabs. The first is for jack audio, the second is jack midi, and the third, alsa midi16:04
zequencejack audio and midi will only show devices when jack is running, while alsa midi is always on16:05
zequenceIt's a bit complicated, but that's what you get when you need so many different tools to do one thing16:05
GridCube:/ im trying to use idjc but its failing to launch the jackd service22:41
holsteinGridCube: i woud start JACK first, and get it running stable22:41
GridCubetrying to manually launch it results on an error, Failed to acquire device name : Audio0 error : Method "RequestRelease" with signature "i" on interface "org.freedesktop.ReserveDevice1" doesn't exist22:41
GridCubeit used to autolaunch it by itself22:42
holsteinGridCube: i *never* trust that22:42
GridCubeit worked before, after i upgraded to 12.1022:42
holsteinGridCube: you'll want to get JACK running stable and then go from there22:42
GridCubebut how22:42
holsteinGridCube: qjackctl is the GUI22:43
GridCubei tried that too22:43
holsteinGridCube: could be as simple as not being in the audio group22:43
GridCubeD-BUS: El servidor JACK no puede iniciarse. Disculpa22:43
holsteinwhat would i do? close everything and run "ps aux | grep jack" in a terminal and kill any jack running22:43
holsteinthen, i would run "gksudo qjackctl" and select my audio device and hit "start",.. see that it starts with no errrs22:44
holsteinerrors*22:44
holsteinthen, i would run as normal user... troubleshoot from there22:44
GridCubekay22:44
holsteinalso, check this ou22:44

GridCubegridcube  17892  0.1  0.2 168992 10880 ?        Ss   19:36   0:00 /usr/bin/jackdbus auto22:45
GridCubethats what its suppose to be there?22:45
holsteinGridCube: well, i would kill it and start over. that could be there if idjc tried to start it and its just sitting there broken22:46
GridCubei can sudo it22:47
holsteinGridCube: ok.. but it fails as normal user?22:47
GridCubeyes22:47
holsteinsudo adduser you audio22:47
holstein^ try that.. i forget if you have to logout to take effect22:47
GridCube:D apparently it works without reloging22:48
holsteinsounds right. anyways... thats probably all there is to it22:49
GridCubeja :D HAHA :D AHAHAHAHAHA PERFECT22:49
holsteini would start and stop JACK from the gui.. the qjackctl... jack control22:49
holsteinotherwise, it can be running in the background22:49
GridCube:) okay will do that holstein22:50
GridCubethank you verymuch22:50
holsteinGridCube: cheers!22:50
Haohmaruexcuse my dumb question.. what do you normally do when you need to get a new app on linux?23:28
Haohmaruyou download it in some .zip or similar package, then manually install it or unzip it somewhere, or do you always use some kind of funky h4x0r commands?23:29
GridCubeHaohmaru, you go to the software center and look for it23:32
GridCubeif you know how its called you can also >> sudo apt-get <<it23:33
Haohmarui currently need to install my IDE - Code::Blocks23:33
Haohmarui've been using it on windows23:33
GridCubeif its in the repos then its easy23:33
zequenceHaohmaru: Most applications live in something we call a repository23:33
zequenceholstein: Ubuntu Studio is an official flavor of Ubuntu, and that means, we share the same repository23:34
Haohmarusource code?23:34
zequenceholstein: It's pretty much like an app store, except everything is for free23:34
zequenceSorry holstein23:34
zequenceholstein: ^23:34
zequenceHaohmaru: ^23:34
zequenceDamn!23:34
Haohmaruappstore - i'm not into these things ;]23:34
zequenceHaohmaru: Use the software center to look for apps23:35
Haohmaruokay then23:35
zequenceHaohmaru: Not everything shows there, but that's the easiest way23:35
Haohmaruthat's weird, but if that's how it's done.. *shrug*23:35
zequenceHaohmaru: It's kind of simpler to find all your apps in one location, don't you think?23:35
zequenceInstead of googling for them23:36
zequenceAnd downloading23:36
zequenceAnd installing23:36
Haohmaruwell i'm an old-fashioned win9x user23:36
Haohmaruand this is too alien for me still ;]23:36
GridCube:D this is so much better23:36
zequenceHaohmaru: If you want to have access to everything, you'll either use synaptic, or the command line23:37
zequenceHaohmaru: When you get used to the command line, you rather not mess with slow gui apps23:37
GridCubeyou dont need to get cracked software or unknown zips from weird places23:37
GridCubeall its in the same place23:37
zequenceHaohmaru: Try this in the command line: apt-cache search vlc23:37
Haohmarubasically i'd like to compile my app for linux23:37
zequenceHaohmaru: Then, if you want to install: sudo apt-get install vlc23:37
GridCubeHaohmaru, ha, you will have to learn quite a few before you get there :)23:38
Haohmaruuhm23:38
GridCubeits not so hard, but you need to know the basics first23:38
zequenceHaohmaru: Let me give you a tip of things you might want to have right away: sudo apt-get install vlc ubuntu-restricted-extras23:38
Haohmaruthe project is in codeblocks format23:38
zequenceHaohmaru: You can get the source to any application by doing: apt-get source <application>23:38
Haohmaruit uses a crossplatform lib for almost everything23:39
zequenceHaohmaru: Do this: sudo apt-get install codeblocks23:39
Haohmaruso i just need CodeBlocks cuz i can't compile from commandline ;]23:39
zequenceHaohmaru: You can find codeblocks in the software center23:40
Haohmaruhm23:40
GridCube!find codeblocks23:41
ubottuFound: codeblocks, codeblocks-common, codeblocks-contrib, codeblocks-contrib-dbg, codeblocks-dbg23:41
Haohmaruhah, it runs now23:41
GridCube!info codeblocks23:41
ubottucodeblocks (source: codeblocks): Code::Blocks integrated development environment (IDE). In component universe, is optional. Version 10.05-2.1 (quantal), package size 1583 kB, installed size 4499 kB23:41
zequenceHaohmaru: Either use "software center"(easy), "synaptic"(medium hard - not preinstalled), or "apt"(command line tools)23:41
Haohmaruyey, my project is here, now i gotta linuxify the missing bits ;P~23:42
Haohmaruthanks ;]23:43
zequencehttp://imagepaste.nullnetwork.net/viewimage.php?id=572623:45
zequenceIn fact, what Windows and Mac are doing now with their app stores, that's how package management has been done on Linux for ever23:46
zequenceUbuntu is creating a commercial repo now, but it's not really related to the repo where you get the free software23:47
zequenceMost of the applications that are in Ubuntu, come directly from Debian23:47
zequenceDebian being a volunteer project, there isn't much commercial interest in how that is organized, so that means Ubuntu is pretty free and open too23:48
Haohmarui'm not following microsoft/apple23:48
Haohmarumy phone doesn't have a camera even ;]23:49
zequenceHaohmaru: I'm surprised the battery is still working. Or are you able to buy phones without cameras these days?23:49
zequenceMine at least has a camera23:49
zequenceBut, it doesn't have touch screen, or IQ23:50
Haohmaruzequence, i think i used my nokia 3310 till 200823:50
Haohmaruthat's when i got this "newer" nokia which i still use today23:51
Haohmaruso that's my 2nd mobile phone23:51
Haohmarui don't even know the model ;]23:51
zequenceMine is a Nokia too. Nokia really used to rule, before they got overrun by modern times, and then by MS infiltrators23:52
Haohmarui don't like touchscreen, touchpads..23:52
Haohmarudon't like rubbing a screen ;]23:52
zequenceIf I had the money right now, i'd get a Nokia N9, just cause it's one of a kind23:53
Haohmarui don't want a smart(ass)phone ;]23:53
Haohmaruall of them are the same, a huge screen, no buttons, uber expensive23:53
zequenceMeego OS. Nokia wouldn't have even released it, hadn't they had a contract with companies like Intel. It's a good phone23:53
zequenceHaohmaru: Probably the Firefox phone won't be as expensive23:54
zequenceI mean, it won't23:54
Haohmarui don't need multi-megapixel camera(s) on a phone23:54
Haohmaruor games23:54
Haohmarusure, kids LOVE that23:55
zequenceUbuntu phone will be a portable PC. Maybe not the first releases, but further down the line23:55
Haohmarui recently read somewhere about some phone with a 40MP camera <- wtf23:55
Haohmaruthat's plain stupid23:55
zequenceNot really23:56
zequenceYou just put it in a dock, and it becomes a PC23:56
Haohmarui meant about the camera ;]23:56
zequenceIf you plug a hdmi cord in it, it become your Ubuntu TV23:56
zequenceAh, yeah23:56
zequence:)23:56
Haohmaruit can't take pictures like those i can take with my 16MP DSLR ;]23:57
zequenceI'm not much of a photographer myself23:57
Haohmaruthose who don't understand only compare the numbers23:57
GridCubezequence, i use a nokia 1100 :323:58
zequenceGridCube: I have one of those23:58
GridCube:D i use that one regularly, but i do have an E523:59
