Hello. I'm running LTSP on Ubuntu 8.04 in LDM_DIRECTX=yes mode on several machines. Since last wednesday the clients on one machine don't use that mode anymore and wrap everything in an ssh connection (resulting in heavy CPU load). Where can I find log files that couls tell me WHY it doesn't work anymore?
02:52bobby_C has joined #ltsp
02:55
<alkisg>
vlt: that only happens for that one client? Are you overriding LDM_DIRECTX specifically for that client in lts.conf, perhaps from a [mac-address] section?

<vlt>
alkisg: I found it. It only happened on one server (of five). It was a syntax error in its lts.conf and so the LDM_DIRECTX wasn't parsed.
03:09
<alkisg>
Nice
03:10
<vlt>
The syntax error was this line: "######### edit 2010-09-01"

I replaced "#########" with "#" and now it works.
03:12
<alkisg>
Weird though, that shouldn't be a syntax error
03:12

Interesting syntax error, btw.

hi
13:36
what is the current best practice for building a fat client on ubuntu lucid?
13:36
<alkisg>
!fatclients
13:36
<ltspbot>
alkisg: "fatclients" :: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients

<moldy>
alkisg: thanks :)
13:37Mobe has joined #ltsp
13:37
<moldy>
i was confused about which documentan applies :)
13:39
<alkisg>
Yeah that's a constant problem with wikies, we're trying to put a "It applies to ubuntu versions ...XXX" in top of them all
13:41
<Lumiere>
alkisg: there should be a template for that
13:41
{{appliesto|lucid}}?
13:42
<alkisg>
Lumiere: if you can get the ubuntu wiki guys to program that in their moinmoin, it'd be very nice :)
13:42
Right now we're just using a colored table
13:42
<Lumiere>
lol moinmoin
13:42
nm QQ
13:43
<alkisg>
I think the best option would be to have a different namespace (e.g. https://help.ubuntu.com/community/UbuntuLTSP/10.04/FatClients) and an easy way to copy pages to new versions...
13:44
I once tried to use categories, but it looked like too much change to some people so I didn't continue it...
13:44
<Lumiere>
well
13:45
categories would make a ton of sense
13:45
across the entire ubuntu wiki
14:12
<johnny>
how does one unsubscribe from a bug category?
14:12
i can't find the ui
14:13
or package bugs.. whatever you wanna call it

johnny: if you mean in launchpad, why not ask in #launchpad?
14:17
<johnny>
because i figured you might know :)
14:17
opening up channels with (potentially)large users list is something i do as a last resort

15:04
<bernardo0cd0>
where do I change the ssh server port in a LTSP client?
15:04
<vagrantc>
!lts.conf
15:04
<ltspbot>
vagrantc: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
15:05
<vagrantc>
hrm.
15:05
apparently that URL is dead
15:05
bernardo0cd0: apt-get install ltsp-docs ; man lts.conf ... look for SSH_OVERRIDE_PORT
15:05
<alkisg>
Works for me
15:06
<vagrantc>
alkisg: odd. it most certainly doesn't work for me.
15:06
<alkisg>
It redirects here: http://manpages.ubuntu.com/manpages/maverick/en/man5/lts.conf.5.html
15:06
Does that work for you vagrantc? ^^
15:06* vagrantc wonders if that redirect was implemented in javascript
15:06
<alkisg>
Could be... lemme check
15:07
Yup... // Try redirecting to a page of search results
15:07
<vagrantc>
?
15:07
<alkisg>
That's part of the javascript in the redirection page
15:08
..it ends in: location.replace('/cgi-bin/search.py?cx=003883529982892832976%3A5zl6o8w6f0s&cof=FORID%3A9&ie=UTF-8&titles=404&lr=lang_en&q=' + q);
15:08
So I guess if one has javascript disabled, redirection won't work
15:08
<vagrantc>
wonder if we could have a more distro-agnostic location...
15:09
<alkisg>
It'd be better, but where?
15:09
The sf wiki isn't automatically updated, we need to do it manually, and not all of us have access to do that
15:10
<vagrantc>
right...
15:12* vagrantc wonders if debian has a place to look up the manpage
15:12
<johnny>
shouldn't we all have access to it :(
15:13
<vagrantc>
well, duh.
15:13
i just know that the debian package is more up to date than ubuntu at the moment
15:13
stgraber: speaking of which, you might put in a sync request for ltsp-docs
15:13
ubuntu supports dpkg source format 3.0 (quilt), yes?
15:16
<alkisg>
johnny: it's an sf restrictions, any wiki editors must be sf users written in a special page on the wiki. If anyone is interested he can tell sbalneav to put him there, it's just not automatically done :-/
15:16
<bernardo0cd0>
another question, is possible to add a delay in rdesktop to ldm start first?
15:19
or there's another method to set ldm as default screen?
15:25
<alkisg>
SCREEN_DEFAULT in lts.conf
15:27
<bernardo0cd0>
hmm, this option doesn't seem to be on docs....
15:27
i I should put the screen number? like "08" or "8"?
15:27
*should I
15:28
<alkisg>
08
15:28
<bernardo0cd0>
thank you!
15:28
<alkisg>
Hmmm or maybe 8, check both of them
15:29
<bernardo0cd0>
hmm, with 08 didn't work, let's try 8
15:30
<alkisg>
distro/version?
15:30
(if i'm reading ltsp-client-core correctly, both should work)
15:31
*ltsp-core

Ah, then no, it's not there yet
15:32
Maybe it's on the backports or something, vagrantc? ^
15:32
<bernardo0cd0>
build all again....
15:32* bernardo0cd0 cries
15:33
<alkisg>
You can just put a chvt in a script, no big deal :)
15:33
<bernardo0cd0>
where is he?
15:33
you mean a "sleep"?
15:33
<alkisg>
chvt == change vt
15:34
To switch to vt8 or wherever you want
15:34
<bernardo0cd0>
and where's the screen scripts?
15:35
<alkisg>
/opt/ltsp/i386/usr/lib/ltsp/screen.d/ldm
15:39
<bernardo0cd0>
thanks, i simply put an sleep, it's working perfectly

has anyone mixed up a light linux (like puppy, antix, lubuntu)) with ltsp?
18:53
<vagrantc>
mixed up?
18:54
<AndyGraybeal>
yea, i don't know it's not the right terminology... like.. instead of having regular ubuntu 10.04 and ltsp... doing something like puppy with ltsp

<johnny>
AndyGraybeal, nobody really has. but they could
22:28
it's just that nobody here uses it
22:29
AndyGraybeal, scott balnaev was considering a much tinier distro as well, so ltsp would be able to work with much older clients
22:29
AndyGraybeal, but even folks with popular distros like slackware haven't done it yet
22:30
ps: ltsp used to be a custom distro based off of redhat, but it became too much of a burden to maintain, and many folks wanted to be able to use their own distro's installation/customization tools
22:30
oh.. and package sets
