cdealer__, look at the blacklist file in teh chroot, add a line "blacklist pcspkr" to it, then you need to run update-initramfs -u, exit the chroot and run ltsp-update-kernels

otavio: i'm not sure what's causing the pt_BR translation to break ... when i updated the es translation, the lintian warning from lintian.debian.org went away ...
11:10
otavio: but when i run lintian on my own builds, it's fine ...

otavio: i think the man page issue affects ldm as well ... let's do an upload there fixing the manpage issue, add the debian-maintainer header, and set the priority to medium ....
11:17
otavio: if it migrates to testing before ltspfs does, it will break local device support anyways ...

guys, any idea of a tool to find out which vendor ID a client sends?
11:24
I'm trying to debug a new PXE image and it complains that it doesn't receive its TFTP file
11:24
I use dnsmasq, with the following options:
11:25
<vagrantc>
supposedly wireshark (a.k.a. ethereal) can help with that
11:25
<Q-FUNK>
dhcp-vendorclass=pxe,PXEClient
11:25
dhcp-boot=net:pxe,/ltsp/i386/pxelinux.0
11:26
<vagrantc>
that sounds like what it should be, in theory, at least
11:30
i should start testing with dnsmasq
11:30* vagrantc fires up virtualbox
11:33Guaraldo has left #ltsp
11:37
<cliebow_>
Q-FUNK: yeah...wireshark should show you option 43 or 60 or something

otavio: uploaded ltsp, should i wait on ldm to make sure the fix actually works?
12:53
otavio: and is it ok to make ldm urgency medium?

ok, it seems that dnsmasq produces dhcp that some PXE implementations don't like. switching to dhcp3-server suddenly made this work.
14:07
however, still no X
14:07
but at least now I get something on bootup, which is a good start :)
14:08
brb
14:08Q-FUNK has quit IRC
14:18
<vagrantc>
otavio: well, i sent you an ldm upload email - not sure if we should actually upload till we can verify that it fixed the issue with ltsp.
14:21Q-FUNK has joined #ltsp
14:22
<Q-FUNK>
any hint for debuging why X might fail to launch?
14:23
<vagrantc>
Q-FUNK: have you made any modifications to lts.conf ?
14:23
<Q-FUNK>
I don't use any
14:23
this is a fresh chroot for Gutsy
14:24
the only change is that I installed newer packages for xserver-xorg-core and xserver-xorg-video-amd (both known to work fine on a normal Gutsy)
14:24
<vagrantc>
Q-FUNK: does it produce an error message when it fails? does it try to start X, and then switch back to console?
14:25
<Q-FUNK>
I think it tries to start it, since I hear the monitor making the click it usually does when it tries to change to X
14:25
but I'm back to a blinking cursor right after
14:26
<vagrantc>
Q-FUNK: set in lts.conf SCREEN_07=ldm and SCREEN_08=shell ... reboot the thin client, and then switch to vt8 and check /var/log/*
14:27
alternately, you can set a root password and rebuild the image ...
14:32
<Q-FUNK>
[Default]
14:32
SCREEN_07=ldm
14:32
SCREEN_08=shell
14:32
?
14:33
<vagrantc>
sure
14:38
<Q-FUNK>
ok.. it seems that /etc/dhcp3/ is no longer the location used for dhcpd.conf
14:43
vagrantc: about dnsmasq, it seems that when it passes the dhcp options, it misses an end of line character that some fuzzy PXE implementations don't like. various threads exist on the subject, as reported by $searchengine, but upstream never bothered to fix it.
14:44
<vagrantc>
for shame
14:44
<Q-FUNK>
it's probably trivial to fix
14:44
<vagrantc>
i think i've only used it in situations where i'm always sending all options ... haven't tested the conditional stuff much

good afternoon
15:02
i need some help
15:02DonSilver_ has joined #ltsp
15:02
<Q-FUNK>
ok, finally got X, except that the colors are really weird and moving the mouse over the ldm preference icon makes X crash

i have configured a sip phone in the thin clients but the sound i hear in the client is poor
15:03
<vagrantc>
Q-FUNK: nice.
15:03
<bartolomeo80>
on the other side they listen to me fine
15:03
can anybody help me?
15:04
<vagrantc>
bartolomeo80: remote sound is going to have higher latency
15:05
bartolomeo80: best option would be to run the sip phone on the client itself, but that isn't exactly a trivial task at this point.
15:05
<bartolomeo80>
the strange thing is that i play an mp3 song and it sounds perfectly
15:05
why
15:06
<vagrantc>
latency doesn't matter as much when it is streaming one direction
15:06
<Q-FUNK>
[Default]
15:06
X_DEFAULT_DEPTH=24
15:06
<vagrantc>
but you're dealing with both a microphone and a speaker ... so the timing becomes more important
15:06
<Q-FUNK>
is this still supported?
15:06
<vagrantc>
Q-FUNK: i don't think by that name ...
15:07
<bartolomeo80>
can i use 2 sound cards?
15:07
<vagrantc>
bartolomeo80: well, the timing is still going to be an issue.
15:08
Q-FUNK: X_COLOR_DEPTH=24
15:08
<bartolomeo80>
so, must i improve performance in the server ?
15:08
<vagrantc>
bartolomeo80: like i said before ...
15:09
bartolomeo80: you probably need to run the sip phone software on the thin-client itself, not on the server.
15:09
bartolomeo80: it is not a trivial task.
15:09
<bartolomeo80>
wolud you tell me wher to find the info to do that?
15:10
<vagrantc>
there isn't much information, really...
15:10
bartolomeo80: which linux distro and version are you using?
15:10
<bartolomeo80>
xubuntu 7.1
15:10
<vagrantc>
7.10 ?
15:11
or 7.04 ?
15:11
<bartolomeo80>
7.10
15:11
<stillflame>
has anyone set up ltsp as kiosks with a time limit of some sort?
15:11
<vagrantc>
ok ... you have two basic approaches ... run all the applications on the thin client ...
15:12
bartolomeo80: that option is not terribly difficult if you can use an anonymous, unauthenticated user that doesn't need to save data anywhere.
15:13
bartolomeo80: the other option is to make local application support work, which is a work in progress and as far as i know not really working yet.
15:13
stillflame: like, pay per hour sort of things?
15:13
<stillflame>
not for pay, but yeah.
15:13
<vagrantc>
ah.
15:14
just to prevent people from hogging the public terminals...
15:14
<stillflame>
right, one hour per person limit... it would need either a user database, or an admin enabling terminals for one hour at a time, i guess.
15:15
<bartolomeo80>
vagrantc: i really apreciate your help; i'll tell you if i can make it work. bye
15:16
<stillflame>
i think i may just recommend they use a signin sheet or something, instead.
15:16
<vagrantc>
stillflame: well, you could try the modified honor system approach ... have an X application running in the background that gives a 15, 5 and 1 minute warning and then logs the user out ...
15:17bartolomeo80 has left #ltsp
15:17
<stillflame>
ah, right. are there examples (or even debian packages in etch) of those?
15:17
<vagrantc>
not off the top of my head, but it probably wouldn't be too hard to write one
15:17
maybe you could do it with italc ... ?
15:18
<stillflame>
mmm
15:18
thanks.
15:18cliebow_ has quit IRC
15:19
<vagrantc>
stillflame: i think the tricky part is having some way to check for idleness, and then starting over from 0 ...
15:20
certainly would be a nice application to have ...
15:20
and many people have requested the time limit stuff before
15:21
more for pay by the hour sort of things ...

hi, anybody about using debian?
15:29
debian + gnome that is
15:30
<vagrantc>
what do you need to know
15:30
?
15:30
<johnny>
do you use gksu with sabayon and other System scripts?
15:31
System | Administration links that is
15:31
<vagrantc>
haven't used sabayon at all
15:31
<johnny>
do you have any others in there that use gksu ?
15:31ogra has quit IRC
15:32
<johnny>
if so, try starting one of them , type your password, and then close it
15:32
and then open it again
15:33
see if the busy pointer takes awhile
15:36zodman has quit IRC
15:36
<vagrantc>
i haven't really used gnome much- i only periodically use it to test ltsp
15:37
<johnny>
i notice a bug in ubuntu, wanted to see if it was present in debian.. since other distros use other methods than gksu
15:37
something goes wonky with startup-notification
15:37
the mouse pointer stays busy, just wondering if i need to point the bug elsewhere
15:40
<vagrantc>
Q-FUNK: definitely appears to work with VirtualBox's PXE support and dnsmasq ... probably the workaround would be to default to PXE if nothing else is defined ...
15:41
<johnny>
at least i obsoleted some of the debian patches to sabayon ;)
15:44
<Q-FUNK>
vagrantc: how do we configure pixel depth during LTSP startup? do we run Xorg -depth ?
15:45
the X log shows that X somehow falls back to 8-bit, instead of using the -amd driver's native 24-bit.
15:46DonSilver_ has joined #ltsp
15:46
<vagrantc>
Q-FUNK: by default, it generates /etc/X11/xorg.conf using Xorg -configure, and then tweaks xorg.conf
15:47
Q-FUNK: look at the client's /usr/lib/ltsp/configre-x.sh
15:47
<Q-FUNK>
and it tries to get the maximum depth of the monitor+chipset from where? DDC?
15:54
<vagrantc>
probably
15:55
Q-FUNK: you're reaching into the limits of my knowledge on the subject :)
15:55
<Q-FUNK>
hehe, ok :)
15:56
<vagrantc>
the basic jist is Xorg configure's itself, and we tweak the configuration file from there

Q-FUNK: read the code
16:11
most of the X_* settings in lts.conf, though
16:11
just a bunch of sed ...

17:47
otavio: just looked at the amd64 .deb for ltsp built by a buildd, and it had the manpages.
