growlyaesome brazilian here ?00:00
msaulI have a question regarding Server Edition Hardy Heron...00:41
msaulIn previous version it ran automatically in X-Windows...00:41
msaulThis version, it doesn't, is this to increase performance?00:42
msaulIn this case, is the idea to log in graphically to perform00:42
LaserJockmsaul: how do you mean?00:42
msaulWhen I installed desktop - full graphical00:42
msaulWhen I wiped system and installed server, it is just text based00:42
msaulNo graphics00:43
msaulIt mentions this in documentation as difference00:43
LaserJockservers generally don't have graphical programs on them00:43
msaulbetween 8.04 desktop and server versions...00:43
msaulCan LTSP be run on desktop version?00:43
LaserJocksure00:43
msaulSo I could install just desktop versions00:44
LaserJockwell00:44
msauland it has LTSP automatically installed?00:44
LaserJockfirst tell me what you're trying to do00:44
msaulSetting up lab with 15 thin clients00:44
msaulAlready did over 3 years00:44
msaulwith high schools with 5.10, 6.04, 6.10 and 7.1000:45
msaulLiked the automatic install of LTSP00:45
msaulso I could connect00:45
LaserJockok00:45
msaulto thin clients with PXE 2.0 nic cards00:45
LaserJockso you want to get the Ubuntu Alternate CD00:45
msauli.e. kiss principle00:46
msaulI can understand if server version is more efficient00:46
LaserJockno, it's not really about that00:46
LaserJockthere's only one CD that will automatically install LTSP for you00:47
msaulIs that the server edition?00:47
LaserJockno00:47
LaserJockthe Ubuntu Alternate CD00:47
msaulI saw that, but was confused ...00:47
msaulwasn't intuitive to me...00:48
msaulwhen selecting download path...00:48
LaserJockcheck out https://wiki.edubuntu.org/HardyClassroomServer00:48
msaulThanks, I will do that, and burn that CD...00:48
LaserJockThe server edition won't work because LTSP is a desktop server00:48
LaserJockso it needs all the desktop packages00:48
msaulOK00:49
msaulI will check out your link and save for future reference....00:49
msaulThanks00:49
LaserJockno problem00:49

LaserJockogra: wow, gcompris is up-to-date. I thought for sure we'd need a merging :-)01:35
ograheh01:35
ograi only have four pkgs on the list01:36
LaserJockI don't have any in Main01:36
LaserJock2 in Universe01:36
ogralenny is keeping debian from doing updates i guess01:36
LaserJockthat may be it yeah01:36
ograi know vagrant is *very* cautious to do any updates01:36
LaserJockor maybe we did a better job in Hardy of keeping up-to-date :-)01:37
ograeven though he doesnt belive lenny will happen before dec01:37
LaserJockmy bet is on lenny ;-)01:37
ograyeah01:37
LaserJockwell, I go with the release date and then add ~ 6 months01:38

johnny_uggh01:38
johnny_is flash broken on amd64 again?01:38
* LaserJock cries01:38
LaserJockjohnny_: in general or just on LTSP?01:39
johnny_in general01:39
ograshould work with nspluinwrapper01:39
ogra+g01:39
johnny_libgcc_s.so.101:40
johnny_says that is missing01:40
johnny_that is npviewer.bin itself01:46
ograweird01:46
ograi know many people use it01:46
johnny_it's a registered bug i think too..01:46
johnny_now if only i can find it01:46
johnny_18047801:48
johnny_it is bug 18047801:48
johnny_i am just not good enough debian/ubuntu to be able to fix this crap01:50
johnny_but that is what we have..01:50
johnny_an earlier version if ia32-libs has it i think01:50
johnny_Flash Plugin installed.01:51
johnny_/usr/lib/nspluginwrapper/i386/linux/npviewer.bin: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory01:51
johnny_nspluginwrapper: no appropriate viewer found for /usr/lib/flashplugin-nonfree/libflashplayer.so01:51
johnny_ogra, any ideas for me?01:56
johnny_to figure this thing out?01:56
ogranot really, i'm not really familiar with ia32-libs, but i know many people use it with success01:57
johnny_ugghz02:01
johnny_i feel like since the upgrade didn't complete all the way through02:02
johnny_i missed af ew things02:02
johnny_ie: the cleanup phase never ran02:02
johnny_also.. the internet just goes down randomly now02:02
johnny_i can't pinpoint why02:02
johnny_but at least once a day, i have to restart the computer02:02
ograrun u-m again ?02:02
johnny_it says it's done02:02
johnny_but it's hard for me to believe02:03
ogradid you do y proper update from gutsy-updates before starting ?02:03
ogras/y/a02:03
johnny_i did do all the updates i had02:03
johnny_before starting the upgrade02:04
ograstrange02:04
ogralsb_release -a ?02:04
johnny_it says hardy02:04
johnny_there goes the internet again02:04
johnny_only a reboot solves it02:04
johnny_there's nothing in dmesg02:04
ograNM works properly ?02:06
johnny_i guess.. :)02:06
ograand ubuntu-desktop is installed?02:06
johnny_yes02:06
ograi dont really have an idea ... you might want to talk to mvo tomorrow who does u-m02:07
johnny_well .. this internet problem is more important02:09
johnny_i'm getting serious flack now02:09
johnny_there's nothing in the logs either :(02:10
johnny_i need to figure out if it's the driver02:11
johnny_or some random software02:11
ograwhat card ?02:11
johnny_b4402:11
ograeeek02:11
johnny_it is onboard02:11
* ogra boggles facing the boradcom02:11
johnny_it worked great until hardy02:11
ografirmware out of date ?02:12
johnny_for wired ?02:12
johnny_wired02:12
ograhmm, i never had a wired bracom02:12
ogra*broadcom02:12
johnny_it's not bcm43xx or anythign02:12
johnny_it's just b44 :)02:12
johnny_hmm.. maybe i should migrate back to the 22 kernel02:12
ograthere is a fresh kernel in hardy-proposed02:13
johnny_so.. what should i do to upgrade02:14
ograhmm, nothing about b4402:14
johnny_i just wish i could tell if twas the driver somehow02:15
johnny_any suggestions on that?02:17
johnny_test02:20
johnny_am i still here02:20
ograyes02:20
johnny_uggh.. stupid internet02:21
ograi wont be much longer ... nearly 3:30 here02:21
ogra(am)02:21
johnny_yeah.. figured02:21
kingair_sixhello, I am a relative noob in linux and have some issue with burning cds. i probably tried 3 different media and it always came up with an error. now online it says to add my username after "disk" in etc/group , so far so good, but how can I save group after I changed it?02:29
kingair_sixany idea?02:39
johnny_uggh... this is lame02:44
johnny_after every upgrade of ubuntu.. i have to spend at least 6 hours trying to figure something out02:45
kingair_sixwhat is that?02:45
kingair_sixthis burning stuff is so devestating... going through cds like sherman through atlanta...02:53
LaserJockkingair_six: whe does it give you an error?02:56
kingair_sixwhen using the nautilus feature with right klick "write to disc"02:58
kingair_sixit gives it immediately02:58
kingair_sixwith k3b it does not let me choose a drive or does not recognize the empty media02:58
LaserJockman02:59
LaserJockthat stinks02:59
LaserJockI haven't had problems like that for years :/02:59
kingair_sixnow i found one possible solution, to write my username into etc/group after disc, but i couldnt figure out how to save groups after i edited it, wouldnt let me02:59
kingair_sixi'm sorry to bring it up... i just started with linux three days ago02:59
LaserJockyou need to have administrator permissions02:59
kingair_sixwell, it's an administrator account03:00
LaserJockhow did you edit it?03:00
* johnny_ cries 03:00
LaserJockwhat app?03:00
kingair_sixholdon, checkin03:00
kingair_sixgedit03:00
LaserJockfrom the menu?03:00
kingair_sixjup, rightclick-> text editor03:01
kingair_sixor something like that03:01
LaserJockok, I'll give you an easier way to do it03:01
kingair_sixthx!03:01
LaserJockgo to System -> Administration -> Users and Groups03:02
kingair_sixyep03:02
LaserJockhit "unlock"03:02
kingair_sixk03:02
LaserJockthen hit the "Manage Groups" button03:02
kingair_sixalright,03:02
LaserJockthat gives you a list of all the groups03:03
kingair_sixyup03:03
LaserJockkingair_six: not sure if that'll help your Cd problem but that's the best way to mess with users and groups03:06
kingair_sixoke, then i just add disk there?03:07
LaserJockno03:09
LaserJockfind the disk group and hit Properties03:09
LaserJockthen it'll give you a list of users that you can add to it03:09
kingair_sixit is not in there though?03:09
LaserJockok03:10
LaserJockhmm03:10
LaserJockkingair_six: do you have a link for the reference that said to use the disk group?03:13
kingair_sixnope, i'm sorry, was on a different computer03:13
LaserJockk03:13
LaserJockwhat error do you get with the "write to disc" method03:14
LaserJock?03:14
kingair_sixaehm, hang on a sec03:17
kingair_si1alright, aehm03:18
kingair_si1There was an error writing to the disc:03:19
kingair_si1Could not run the necessary command: Failed to execute child process "wodim" (Permission denied)03:19
kingair_si1alright, it just worked for the first time on a try with gnome baker or so, i gotta leave now, thank's for the help, appreciate this open community!03:22
johnnydpkg -L ia32-libs | grep gcc06:34
johnnynothin..06:34
* johnny looks for the old version06:34
johnnyhmm.. guess not..06:45
johnnyok.. wrong place for that..06:53
johnnymust be a path issue somehow then06:53
johnnyfinally thought about the issue06:59
johnnywhere does ubuntu handle 32bit library path handling?06:59
johnny i see no /lib/32  in /etc/ld.so.conf07:00
johnnyi don't have any other 64bit ubuntu installs to check with07:00
johnnyoh.. looks like my updatedb wasn't cronned anymore..07:16

killsaladhi all i've got a problem with ltsp-bulid-client it fails to complete and complains about lacks of package xubuntu-artwork-usplash14:04
killsaladany idea?14:04
ograyou ned to use --components main,restricted,universe with ltsp-build-client14:05
ograxubuntu is built from universe now, ltsp only builds from main ackages by default14:05
ogra*packages14:06
killsaladok i see14:06
ograso: sudo ltsp-build-client --components main,restricted,universe14:06
killsaladok - let's find out14:07
killsaladi've got another question : have somebody tested terminals running kde4 ?14:10
ograwhy should that be any different from any other desktop ?14:11
ograit runs on the server in a ssh session or with forwarded DISPLAY ... shouldn make a difference if you run kde 3 or 414:12
killsaladwell i know that i only wondered if Kde4 is light enough14:14
killsaladat least compareble with Xfce14:15
ogralight/heavy will only affect your server14:16
killsaladi'm setting right now LTSP in some NGO - a lot of "voulonteers" are working on therminals and i want to give them the best impression about Linux14:16
ogranot the clients ...14:16
ograso if your server is capable of handling kde4 sessions for every user that should be any issue14:17
ogra*shouldnt14:17
killsaladhm what is capable - it's pentium D 2.8 and 2 GB ram14:18
killsaladthanks for advice - about ltsp-build-clients it worked14:19
ogrageneral rule for an ubuntu desktop: 256M for running the server plus 128M for every running session14:19
ogrado the math :)14:19
killsaladhm i've got 5 termials14:19
ograthen you have a good buffer :)14:20
killsalad;)14:20
killsaladok just one more question14:20
killsaladi've got a printer pluged to terminal it's often 'gets down' and it is nessesery to reboot terminal14:21
killsaladis it mine's issue or is it LTSP wide ?14:21
ograhow much ram does the client have ?14:22
killsalad12814:22
killsaladall cilents have 128 (dell GX1)14:23
ograhmm, should actually be enough14:24
ograwhich release are you using ?14:24
killsaladright now none ;) previously 7.1014:25
ogranone ?14:25
killsaladtoday i've upgraded server to 2GB Ram and bigger drive14:25
ograon what are you running ltsp-build-client atm ?=14:26
killsalad8.0414:26
killsaladproblem was in 6.10 - 7.1014:26
ograthere were some fixes  ...14:26
ograbut also one bug in 8.04 with printing14:26
ograhttps://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/22425914:27
killsaladok - to set a printer i edit lts.conf and add an ipp printer ?14:28
ograthat will affect you as well (workaround included)14:28
ograno, ltsp uses HP Jetdirect14:28
ograyou set PRINTER_0_DEVICE to point to the lp device in lts.conf14:29
killsaladsilly me (i mean JD)14:29
ograand in the users session set up a jetdirect printer pointing to the client IP14:29
killsaladso like in LTSP 4.x14:30
ograwell14:31
ograyou only need one option in lts.conf14:31
ograin 4.2 you needed a whole bunch14:31
ograbut beyond that, yes14:31
ogra(i'm planning to get rid of the last option as well btw :) and automate it through udev if a printer is detected )14:32
killsaladit were nicer if it all was transparent to admin - just plug printer and serwer detects it ;)14:33
ograright14:34
ograwe'll get there :)14:34
ograjust takes development time14:34
killsaladhow about local media - is any progres in this area14:34
ograonly small changes in comparison to 7.1014:35
killsaladmy dummies ;) are confused when i told them you have to go to /media/[username]/drive14:35
ograwell, gnome handles it fine14:36
killsaladhow about xfce?14:36
ograif you would use nautilus instead of thunar :)14:36
ograwhatever thunar uses in the backend doesnt monitor /media14:36
ograbut the ltspfsmounter script is a trivial little python thing, it should be easy to add two lines to put links on the user desktops on plug and remove them accordingly14:37
ograits just nothing we'D ever do my default (putting links on desktops)14:38
killsaladhm - i konw a python14:38
killsaladwhere can i find ltspfsmounter14:39
killsalad?14:39
ogra/usr/sbin/ltspfsmounter14:40
ograon the server14:40
killsaladthx14:40
killsaladwell i would like to contribute to ltsp in ubuntu but i'm only fluent in python and php14:41
killsaladis there something that i can do14:42
killsaladwith such skils?14:42
ograthere are three functions, add remove and cleanup ... removoe the links in cleanup and remove, add a link in add :)14:42
ograpython is fine :)14:42
ograwe dont really do php anywhere14:42
stgrabersome shell scripting knowledges would probably also help14:42
ograindeed14:42
ograbut there is nothing in a shellscript you couldnt also do with py ;)14:43
stgraberindeed14:44
killsaladstgraber: in theory i also know C,C++, Java ;) but i've never wrote somthing bigger than excercise on classes14:47
stgraberLTSP also has some part written in C (jetpipe and ldm IIRC) but most of it is shell scripts and some python scripts14:48
ograjetpipe is still python14:48
killsaladok - a general question has E/K/X/Ubuntu any gui-tool that allows user to change their password14:48
stgraberkillsalad: yep14:48
ograand i dont really want to change it, C would add extra complexity14:48
stgraberSystem -> Preferences -> About Me14:48
killsaladstgraber: not present in Xubuntu14:49
stgraberthat's in gnome, so Ubuntu and Edubuntu14:50
stgraberKubuntu probably has something similar, not sure about Xubuntu14:50
killsaladok - it seams that user manager is capable14:55
* ogra sighs about https://help.ubuntu.com/community/UbuntuLTSP/FirewallConfiguration15:01
killsaladhm i was wandering if it could be possible to have one guest account with ability to multile login15:15
ogratechnically yes15:21
ograbut none of the desktops likes that15:21
killsaladyeah15:21
ogranor firefox or openoffice15:21
stgraberyou would need some kind of temporary home directory that would copy the main one /home/xyz to something like /tmp/xyz.pid. But then changes would be dropped when closing the session.15:49

scrapbunnyserverdoes anyone have suggestions of the best apps/games to run on thin clients for 1st-5th grade?18:27
scrapbunnyserveranyone here running edubuntu classroom server?20:37
johnnyi tend to just call that ltsp :)20:38
scrapbunnyserveras i think you are on the ltsp channel too, i'm looking for recommendations of games or websites that run well on thin clients20:41
johnnyit all depends on your network20:43
scrapbunnyserveri am working on getting more memory but for now we have a dell poweredge with dual core intel xeon 2.40 ghz processors and 3 gig memory. clients are dell gx110 with 128 ram20:46
johnnyand the network?20:46
johnnyi found out recently that our switch has gigabit uplink20:47
johnnywhen i have time to move things around.. i'll see if it makes any real difference20:47
scrapbunnyserverwe have T1 lines and use a gig switch20:48
scrapbunnyserverthink that is right, the recommended switch for ltsp20:49
