VSpikeAnyone got any suggestion for an ultra simple program launcher suitable for nursery/reception age children?  (3-6yrs)01:12
VSpikeI keep seeing these netbooks with really simple launchers, but none of them seem to have made it out into the wider world01:13
HedgeMageVSpike: My son (about to turn 6) has been using plain old Xfce with a selection of programs linked on the desktop since he was about 3.01:13
HedgeMageVSpike: So I haven't had cause to look for anything else.01:13
VSpikeHedgeMage: It's certainly one option, and not a bad one... was just looking for alternatives01:13
VSpikeI thought about wbar01:13
HedgeMageIf you have it narrowed down to 2-3 options I can use my kid as a guinea-pig for you. ;)01:14
VSpike:)01:14
VSpikeHeh, I have 2 of my own as willing testers but thanks for the offer :D01:14
VSpikeTBH I'm more worried about the adults.  I want to recycle this PC a school discarded and give it back for use in the nursery school.01:15
VSpikeI just fear that if it's not instantly obvious, it won't get used or even turned on01:16
* HedgeMage nods01:16
VSpikeFor the adults, the fact that it looks not like windows may make them not switch it on for the kids, or fear it01:16
HedgeMage:(01:17
HedgeMageI hate to see that happen.01:17
HedgeMageOf course, my response is usually to turn it on and stick a kid or two in front, then make them watch what happens.01:17
VSpikeMaybe I just need to go and *show* them a bit .. a couple of top programs, like tuxpaint01:17
VSpikeMine can show the others how to use tuxpaint :)01:17
VSpikeWhat other faves do your kids have?01:18
VSpikeKTuberling is usually popular01:18
HedgeMageri-li, tuxpaint, fillets-ng (though he only half understands it, the secret agent fish have him hooked), ktuberling, monsterz, secret maryo, frozen bubble, gcompris...01:21
VSpikethanks, will check those out01:24
HedgeMagecircus linux, tux racer, and I Have No Tomatos01:24
HedgeMagethat's his whole list right now :)01:24
VSpikeThe graphics on this machine *suck*, which rules out a lot of things01:24
VSpikeTrident Cyberblade01:25
* HedgeMage nods01:25
VSpikeOtherwise, it's OK. Athlon XP 1800+, 1GB of "found" RAM :)01:25
HedgeMagebrb01:25
VSpikeSure01:25
VSpikeFor some reason I can't get a working face browser for GDM, but maybe I just need to enable auto-login01:26
HedgeMageback01:31
HedgeMageI have face browser working -- note that you have to have chosen a theme that works with it01:32
HedgeMageThe only one of those apps I mentioned that might be a problem on old video is tux racer -- the rest are quite tolerant01:32
VSpikehehe ri-li is fun, never seen it before01:37
VSpikeI will investigate the rest, because I've only seen a couple of them01:37
VSpikeYeah, I selected a theme with face browser, just get an empty one01:39
VSpikeI've tried ticking the "include all users" option, and also turning it off an adding users manually01:39
HedgeMagehang on, let me open the configurator here and I will walk you through it. :)01:41
VSpikeOh, ta :)01:41
HedgeMageUnder the "Local" tab:01:42
HedgeMageStyle is "Themed with face browser"01:42
HedgeMageTheme is "selected only"01:42
HedgeMageFrom themes, choose "Happy Gnome with Browser" or "Human List"01:43
HedgeMageThen under the "Users" tab:01:44
HedgeMageCheck "Include all users from /etc/passwd (not for NIS)"01:45
HedgeMagemake sure you have a default face selected, and a faces dir with faces for people to choose01:45
HedgeMageUnder the "Security" tab:01:45
VSpikeAh, you got it, thanks!01:46
HedgeMageStarting about halfway down01:46
HedgeMageset "Minimal UID" to 100001:46
VSpikeDidn't spot that I had to have "Themed with face browser" in style as well as selecting a theme with a face browser01:46
HedgeMageUncheck "Allow local system administrator login"01:46
HedgeMageand check "Only allow login if user owns their home directory"01:47
HedgeMageNo problem!01:47
HedgeMagedo check those security settings even if everything else works, they can save you some headaches.01:47
VSpikeThanks, I have those ones as you say01:48
HedgeMagecool :)01:49
VSpikeJust wondering, is there any way to customise the menus in GDM? I think you kinda need the power ones, but I'd like to get rid of the language and session ones01:49
VSpikeIt's a small thing but I can see people accidentally changing it and then getting confused01:49
VSpikeProbably have to hit the gdm config file01:50
HedgeMagenah01:50
HedgeMageunder the "local" tab:01:50
HedgeMageUncheck "Show Actions Menu" -- it's just under the list of available themes.01:50
VSpikeDoesn't that get rid of the power control options too?01:52
* VSpike tries01:52
HedgeMageI didn't think so, but check and find out01:52
HedgeMageI have it all enabled here.  I'm the only one who uses my laptop, and the other box with a gui is only used by my son and I.01:53
HedgeMageHe's been well indoctrinated in the world of Linux, he can actually select the correct kernel from a list on bootup!  (Our shared box is my dev box, so it's a mix of normal and unstable stuff)01:53
VSpikeHeh it does the exact opposite of what I want :) remove the power stuff, keep the other stuff01:54
VSpikeI'll have a look in the gdm config file and google a bit - just wondered if you knew01:54
HedgeMagehang on let me look at one other thing...01:55
VSpikethose menus (language, session) exhibit a behaviour that I see quite often in ubuntu - they start scrolled down so that the selected option is at the bottom and the only one visible01:55
VSpikeand the rest of the menu is empty space01:55
HedgeMagenope...I have no clue01:57
VSpike:) thanks for looking01:57

cdshan Hello! I have installed ubuntu 8.04 LTS server on my machine.  I have installed ltps and have configured dhcp.  The client boots into to the login screen but gives me an error message saying that .xsessions file is not present and window manager is not found.  What should I do?03:27
HedgeMagecdshan: you might want to repeat your question for ogra -- he knows more about LTSP than me03:32
cdshanthis is the error I am getting after I enter the user name and password:03:36

Nubae-laptophey there folks13:59
Nubae-laptopreporting from Fossdem13:59
Nubae-laptopWhere I had a great talk with the kde guys14:00
Nubae-laptopwho basically reiterated the fact the it is now an education project14:00
Nubae-laptopI strongly agree now with Laserjock and others that we should move to kd14:01
Nubae-laptopkde14:01
* ogra wasnt aware LaserJock wanted that14:02
Nubae-laptopI was shown some example plasmoid apps that were education based that were extremely simply coded but amazingly useful. Basically kde 4 has become THE edu platform (apart from sugar) I think we should seriously discusss the move towards kde for edubuntu14:03
Nubae-laptoplaserjock was the one who inititated this14:03
ograas an optional thing as i understood14:03
Nubae-laptopoptional?14:03
ograwhch exists since gutwsy but isnt maintained14:03
Nubae-laptoplook, the point here is kde-edu has a massive amount of devs compared to edubuntu14:04
Nubae-laptopwe need them14:04
Nubae-laptopwe need plasmoidsç14:04
ograas i understood him he was looking for maintainers taking care of edubuntu-addon-kde14:04
ograwhich is dead since it exists14:04
Nubae-laptopperhaps, because we are going about it the wrong way14:04
Nubae-laptopwe need to really involve the kde community14:04
ograwell, edubuntu is an educational addon14:05
ograand needs to involve both communities of the big desktops14:05
ograor even the small ones14:05
ograin any cas its an addon and shouldnt care about the underlying desktops ... the addon and artwork packages need to integrate with both14:06
ogra(or all three if you count in xfce)14:06
ogranote that the edu apps were always used in a cross desktop manner in edubuntu14:08
ograthe only thing that was focused directly on the dektop was always only the artwork related issues (usplash, wallpaper, icons)14:09
ograif you really want to re-fuel the old desktop wars, go for it ... but imho focusing on a single undelying desktop is the totally wrong approach14:09
ograit is an addon, leave it being an addon and make sure the respective communities help with DE artwork integration14:10
ograthe only time wheer the desktop counted was when we still were building integrated installer CDs ... we siwtched away from that to exactly avoid the desktop specific issues ...14:13
alkisgWell, we should probably start with asking for ltsp to support KDE :P :) :D15:33
ograsend patches :P15:34
ograwe made an attempt pre-gutsy to at least get their volume control working ... but the fixes never made it into productions15:36
ogra-s15:36
ogralocal devices support needs hal integration to properly work with KDE since it doesnt monitor /media like gvfs and gio do15:36
alkisgI'll give it a shot -probably at summer- but you know that greater forces would be needed :)15:36
ograand there is a lot more15:37
alkisgOuch... forget it, I don't know what you're talking about! :D :D :D15:37
ograi know tha stgraber was pretty desparate with all the issues KDE had15:37
ograthough that was 3.x15:37
ograits likely the perfect time to avoid all the issues from the start in KDE 415:38
alkisgSo if hal was used, then that would work in gnome also? Or are you talking about completely different implementations? (about localdevs)15:38
ograthe prob is that you need a connection between the session dbus on teh server and the system dbus on the client for ltspfs via hal15:39
ograonce you have that, you solve ltspfs for all desktops, shutdown/reboot/suspend ... and a lot more15:39
alkisgDoesn't sshfs now support all the things ltsp needs to replace ltspfs? (I thought it was missing some stat* function that got implemented later on...)15:40
ograthe only attempt i have seen yet that could work is a very hackish addition to dbus clled gabriael15:40
ogra*gabriel15:40
ograthat tried to establish an ssh tunnel between two machines to forward dbus15:40
alkisgOK, I'm certain that this isn't for me. :) So I'll just join the fan club with nubae and LaserJock and ask scotty / stgraber and the rest to support KDE :P :D15:41
ograltspfs is two parts ... the transport protocol (ltspfs and ltspfsd) and the mont scripts15:41
ograthe mount scripts need to be replaced by proper hal and dbus implementation, ltspfs transport is fine15:41
ograhacking up sshfs for it would be an option indeed, but the prob lies elsewhere15:42
ograthe ltspfs communication layer needs to be fixed to work with all desktops which means to use hal and dbus instead of scripts that talk though the ssh tunnel15:43
ograhttp://people.ubuntu.com/~ogra/ltspfs-hal-root.png15:43
ograthat was the start of an attempt i made, but due to lacking time i never finished any actual implementation15:44
alkisgArgh... lucky netmobile users...15:44
ograit created an ltspfs root device ... hal would then need to be hacked up to attach all client side devces to this rootdevice15:45
ograthen you could add .fdi files that make it use the ltspfs transport layer15:45
=== nothingman__ is now known as nothingman
nothingmanhi, all21:18
Meshezabeelheya nothingman21:19
nothingmanwhat's new?21:19
Meshezabeelnot much, you?21:19
nothingmanbesides I have three servers going now21:19
Meshezabeelwow :)21:19
nothingmanone's my laptop, and I had some students at my smaller school logged in on laptops as thin clients21:19
nothingmanafter they left, I realized I had to add the fstab entry to mount the /home directory for the fat clients, so I played with that myself for a little bit21:20
nothingmanneed more RAM before things will work right, though21:20
nothingman:-P21:20
nothingmanmy laptop crawls with 5 logged-in thin client users, or 3 fat clients at login screen21:21
Meshezabeellol, it's rare for a laptop to be a server ;)21:22
nothingmanheh21:22
nothingmanno desktops with decent enough specs at that school21:22
nothingmanin fact, when I walk in my laptop's the best suited for the purpose21:23
nothingmanbut I'll probably still have to double my RAM to serve 9 clients21:23
Meshezabeellol, indeed21:25
MeshezabeelI can just hear the fan running at full speed :p21:25
nothingmanactually, it does OK21:26
nothingmanI should probably kill gdm21:27
nothingmangain back about half21:27
alkisgMy laptop (core 2 duo 2Ghz / 4 Gb RAM) works fine as an ltsp server with 8 clients, and I think it could handle twice as much... :)21:28
nothingmanyeah21:29
nothingmanmine's an Athlon 3200 with 1Gb21:29
nothingmanup to 2.0Ghz21:30
alkisg..and 100mpbs ethernet?21:30
nothingmanyup21:30
nothingmanthat's what's gonna kill me, I think21:30
alkisgYeah, with 2 gb ram you could serve 10 clients, but with 100 mbps you won't be able to provide good screen refreshing21:31
nothingmanwell, I'm hoping to use fat clients, but I still have to use a good amount of bandwidth for each client to access the NBD, right?21:32
alkisgI don't think so, at least booting (I didn't test fat clients) wasn't so bad with 100mbps21:33
alkisgI guess it's ok for fat clients21:34
