Hi!
01:30
I'm new to LTSP, and I'm following Debain's HowTo.
01:31
<rcy>
deavid: and hows it going?
01:31
<deavid>
I don't know if it is possible to boot a Client box without using PXE. Instead of his, I want install a LTSP client kernel on it.
01:31
It is possible?
01:32
Or I must use a DHCP?
01:33
I want to use it in places where is another DHCP server

It seems easy to configure the LTSP server; but all tutorails are telling me to enable Network boot on the client.
01:36
I'm reading about Eherboot, but I must know what kind of ROM has the machine to build a boot CD.
01:36
I don't know why I can't simply install Grub onto that machine, and place the kernel for boot...

I'm looking to /opt/ltsp/i386/boot and there's the kernel
01:40
and there is the config
01:41
"DEFAULT vmlinuz ro initrd=initrd.img root=/dev/nfs ip=dhcp"
01:41
it seems that I can replace "dhcp" with the LTSP-Server IP.
01:42
none of you know if this will work or not?
01:43
<ogra__>
deavid, try to drop: root=/dev/nfs ip=dhcp and add boot=local
01:44
<deavid>
ah, ok; thanks!
01:44
how can I tell the client where's the server?
01:44
(in DHCP this is done by dhcp...)
01:45basanta has quit IRC
01:45
<ogra__>
you can use nfsroot=<serverip>:<path>
01:46
<deavid>

morning vagrantc
02:02* vagrantc waves from the train in spokane
02:02
<ogra>
actually "from the train" ?
02:03
<vagrantc>
sitting in the train
02:03
<ogra>
wow, nice
02:03
wlan is something they still miss out on in germany ...
02:03
<vagrantc>
this town has some 2 hours of free wifi program ... decent bandwidth, it seems.
02:03
<ogra>
you got power plugs on every seat though
02:04
<vagrantc>
well, in my car, there's no power plugs, but the one in front has em ... and i apparently can go for about 6-7 hours on battery before i figured that out
02:04
<ogra>
ah, so you dont have it "on the train" actually
02:04
(wlan)
02:04
<vagrantc>
no. i figured since i was at a stop for a while, i'd give it a try ...
02:05
<ogra>
heh
02:06
i tried the lufthansa WLAN on a plane once ... was workable for IRC ... but not really anything more heavyweight
02:06
sadly they dropped that project again ...
02:08
<stgraber>
too bad, having IRC would already be great :) (ok, probably not so useful for most of their customers)
02:10mikkel has joined #ltsp

hmm..
02:14
<vagrantc>
well, time to sync all my bzr repositories with the changes i've made on the train :)

anybody here ever run into pxe-t04 unsupported operation?
02:20
i found out some of my thin clients will pxe boot today.
02:21
2 are now floppyless..
02:21
the 3rd could be.. if i could knew what was going on with that :)

02:41
<deavid>
hey, im triying with "ogra__: you can use nfsroot=<serverip>:<path>"
02:41
but, the path is relative to? or absolute?
02:41
the absolulte path is /opt/ltsp/i386/
02:42
<vagrantc>
that's the one
02:42
<deavid>
192.168.0.1:/opt/ltsp/i386
02:42
ok :)
02:42
isn't loading the root file system
02:43
"Waiting Root file System ...."
02:43
How can I test the server to know if it is providing the NFS?
02:44
<vagrantc>
if you're using NFS
02:45
<rcy>
deavid: try to mount the nfs directory from another machine manually
02:46
<deavid>
This is a good idea; I never used NFS before... I'll try to find some documentation about it.
02:47lexa_ has quit IRC

"mount 192.168.0.1:/opt/ltsp/i386 /mnt" from another host on the network
02:47
<johnny_>
hmm.. anybody have machines with intel boot agent?
02:47
<deavid>
easy :)
02:48
<rcy>
johnny_: yeah
02:48
<johnny_>
with ltsp?
02:48
<rcy>
yeah
02:48
<johnny_>
any problems/
02:48
?
02:49
<daduke>
vagrantc: bonjour!
02:49
<rcy>
istr some clients not booting properly with some intel nics, but generally, no, pretty smooth
02:49
<deavid>
rcy: "mount.nfs: 192.168.3.12:/opt/ltsp/i386 failed, reason given by server: Permission denied"
02:49
Is the server :P
02:49
<johnny_>
not booting properly?
02:50
<rcy>
johnny_: i cant recall off the top of my head though. generally i grab an intel card, and netbooting works, after going into the netboot bios to make sure its trying a network and not a local boot
02:50
<johnny_>
oh.. it's trying to boot..
02:50
<rcy>
johnny_: what problems are you having?
02:50
<johnny_>
it just tells me pxe-04
02:51
err
02:51vagrantc has quit IRC
02:51
<rcy>
deavid: check the logs on the server. check /etc/exports to make sure it looks right
02:51

<johnny_>
unsupported request from 192.168.1.15
02:51
which is actually the IP of the machine itself.. lol
02:51
<rcy>
interesting.... so it gets dhcp?
02:51
<daduke>
vagrantc: Hi. Got a minute?
02:52
<johnny_>
yes
02:52
<rcy>
johnny_: can you post the complete output somewhere?
02:53
<vagrantc>
daduke: my internet connection isn't very stable ...
02:53
daduke: might just ask anyone.
02:53
<daduke>
vagrantc: unfortunately, no. We have an issue here that you might be interested in... talked to ogra already
02:54
<vagrantc>
daduke: try email ... i'll be on a train for about 2.5 more days.
02:55
daduke: ltsp-developer@lists.sourceforge.net
02:55ogra_cmpc has quit IRC
02:55
<daduke>
vagrantc: all right. I can also wait, I think irc would be better than email. Bon voyage!
02:56
<johnny_>
uhmm..
02:56
<vagrantc>
daduke: you can go ahead and bring it up ... but i might disappear
02:56
<daduke>
vagrantc: must be a long train....
02:56
<johnny_>
the complete output is..
02:56
i'mma have to type it
02:59
<daduke>
vagrantc: thing is that one of our users discovered that you can connect to any LTSP client's :6 from anywhere. I had ogra's xeyes directly from Kassel, Germany, and I could also tap all keystrokes. ogra and yours truly weren't able to figure out whether it's a problem of our setup (but why?) or more general. I worked around with iptables now, but that's not the solution.
02:59
<deavid>
rcy: I found the problem!
03:00
nfs-kernel-server is in standalone mode. Not run by inetd server.
03:00
All tutorials are saying that I must change exports file and then restart inetd
03:00
<vagrantc>
daduke: from the very first day of looking at the code for LDM, i have suspected the "-ac" flag being passed to the X server.
03:00
<deavid>
but in my Debian, nfs-kernel-server is a standalone daemon.
03:01
thanks a lot !
03:01
<vagrantc>
daduke: disabled access controls ... access controls are what you use to prevent people from snooping ...
03:02
<rcy>
deavid: that seems weird. i dont think ive ever seen the nfs server being run by inetd
03:02
<daduke>
vagrantc: I don't think I can follow you here... are you aware of the problem?
03:02
<rcy>
deavid: what's the link to the documentation you are following
03:03
<vagrantc>
daduke: i have not actually tried it, but i suspect that LDM's passing the "-ac" option to the X server *may* be what allows anyone to connect to your server.
03:03
hrm.
03:04
<deavid>
rcy: http://wiki.debian.org/LTSP/Howto
03:04
5. Start tftpd. By default, tftpd-hpa is started from inetd. you may need to restart inetd after installing tftpd-hpa.
03:04
<daduke>
vagrantc: with ogra we found that our /root was ro -> no .Xauthority generated, but even with rw and .Xauthority connection was possible even tho X has -auth /root/.Xauthority...
03:05
<vagrantc>
tftpd != nfs
03:05
<johnny_>
rcy, http://pastebin.ca/928786
03:05
<daduke>
vagrantc: it's pretty nasty as soon as ppl actually use the clients for anything real like webmail...
03:05
<vagrantc>
daduke: yes, i would call that a release-critical bug. software that wide open should not be used.
03:06
daduke: "-ac" disables access controls ... which i think means that anything can access your display.
03:07
daduke: file bugs on debian and/or ubuntu about this please.
03:07
<rcy>
johnny_: does /var/log/daemon.log on your tftp server show anything? you might want to crank up the verbosity of the tftpd
03:08
<daduke>
vagrantc: sure. I just wanted to see if anyone else could reproduce the problem
03:09* daduke wonders that nobody else has ever tried this before...
03:09* vagrantc fears that ldm relies on it
03:10
<daduke>
vagrantc: what's the -auth here for then?
03:11
<rcy>
johnny_: ive definitly booted intel boot agent, pxe 2.1 clients successfully
03:11
I'm not where I can test it out now, but I can look at it tomorrow
03:13
<vagrantc>
daduke: well, i'm not in a position to reproduce it at the moment...
03:13
i guess we could possibly X with xinit instead of calling X directly ...
03:13
daduke: the -auth is there because people think it is doing something.
03:13
daduke: but i think -ac trumps that, and nobody had a clue what -ac actually did.
03:13
that's my guess.
03:14
<daduke>
vagrantc: ok, this might keep some ppl busy for some time now I guess ;)
03:15
vagrantc: I'm happy to provide any help and support I can. I wrote a bunch of iptables rules that at least restrict X access to the terminal server. In case anyone's interested...
03:17
<vagrantc>
all users come from the terminal server, though ...
03:18
<daduke>
vagrantc: sure, but it's the best I could do as a quick fix and at least no 'untrusted' ppl from all over the world can snoop
03:18
<vagrantc>
ogra: i've been thinking we could just use X.org's autodetection without a configuration file if none of the configuration options for tweaking the xorg.conf are present ...
03:18
ogra: seems a good deal faster.
03:18
daduke: heh.
03:18* daduke thinks ogra left
03:19ogra_cmpc has joined #ltsp
03:19
<daduke>
vagrantc: the only other idea for a workaround we had would be an OpenVPN tunnel - but that might be more work than actually fixing the problem....
03:20
<deavid>
ha! it's working!
03:20
:))
03:20
<daduke>
ogra_cmpc: hey there! just brought up the 'X wide open' issue...
03:20
<vagrantc>
daduke: i think we just need to use xinit to start the X session ...
03:21
<ogra_cmpc>
daduke, did you manage to test with a proper Xauthority file ?
03:22
<daduke>
ogra_cmpc: well with the rw /root it did create one and the X call seems to use it, but snooping is still possible
03:22
<ogra_cmpc>
weird
03:22
<vagrantc>
ogra_cmpc: i am moderately sure it has to do with passing the X server the "-ac" option, which "-ac disable access control restrictions
03:22
"
03:22
<ogra_cmpc>
vagrantc, where would xinit help here ?
03:22
<vagrantc>
because we wouldn't have to use -ac
03:22
<ogra_cmpc>
hmm
03:23
where does that come from
03:23
<vagrantc>
it would actually set things up properly, than relying on having no access controls to display the greeter.
03:23
the very first ldm code i ever saw.
03:23
and i said "this sounds like a security hole".
03:23
<ogra_cmpc>
i was wondering if we could just use -notcp the encrypted mode
03:23
<vagrantc>
i'm not 100% certain that's the issue, but i suspect it is.
03:23
<ogra_cmpc>
yeah, sounds like it
03:24
i'm not sure ltspfs would survive dropping the -ac though
03:24
that needs testing
03:24
but to be honest i dont really care about the directx mode ...
03:24
as long as we get the default closed
03:25
<daduke>
ogra_cmpc: the problem is also present with LDM_DIRECTX = False !
03:26
<johnny_>
rcy, what tftp server are you using?
03:27
<ogra_cmpc>
daduke, yes thats what i just said :)
03:27
<daduke>
ogra_cmpc: sorry, didn't get it then...
03:27
<rcy>
johnny_: tftpd-hpa
03:27
<ogra_cmpc>
i dont care if its there with directx ,,, but i do care for the default mode
03:31
<daduke>
vagrantc: do you want the bug report in bugs.debian.org or someplace else?

<Nubae>
hi, ogra, u intrigued me yesterday, how would I mount /home via sshfs?
03:58chupa has joined #ltsp
03:58chup has quit IRC
03:58
<ogra_cmpc>
Nubae, find out how to attach to an existing ssh tunnel with sshfs and make a ldm rc.d script for it that gets executed on login
03:59
<Nubae>
would it be fusermount -u /home/username ?
03:59
<ogra_cmpc>
that would ask you for a password
03:59
you need to re-use the existing ssh socket from ldm, else it gets tricky (needs user credentials on teh client then)
04:03
<Nubae>
well ldap is what I'm using on the clients already
04:03
or maybe I'm misunderstanding
04:08Q-FUNK has joined #ltsp
04:09
<deavid>
... another question: how works the login in the ltsp-client?
04:09
I must configure the users vía chroot first?
04:09
or there's a method to use the server's accounts?
04:11
<Nubae>
hmm, I see the problem, sshfs always asks for a password, I guess I can't get it to ask ldap...
04:11
this is going over my head a too much I think
04:13soneyka has joined #ltsp
04:14
<ogra_cmpc>
deavid, ltsp *only* uses server accounts, there are no users on the client and root is locked by default
04:15
<deavid>
thanks! ¿how autenticates these users?
04:15
how can configure any user on ltsp?
04:15
cause it seems to be zero users configured to login on
04:15
<ogra_cmpc>
with the pam setup of the server against the auth mechanism you use at the server
04:16
which is likely to be a standard /etc/passwd login by default in most cases
04:16
but can also be ladap or so
04:16
*ldap
04:16
so all users you create on the server should just work
04:18
<deavid>
but I've tried common logins on the server and does not work
04:18
on ther client*
04:18
then, these logins aren't working
04:19
<Nubae>
use ldap, that works fine
04:19
<deavid>
oook! now it's working;
04:19
need to update ssh keys;
04:20
<Nubae>
yeah
04:20
was gonna say that, if you are on normal thin client
04:20
<deavid>
sorry; I'm a newbie with LTSP
04:20
That is, I'm using a client that boots via GRUB.
04:20
there isn't any PXE, or etherboot on it
04:21
And I didn't found documentation relative to "how LTSP it is mean to do the work"
04:21
:)
04:21
<johnny_>
i use floppies
04:21
<deavid>
thank for your help!
04:21
<johnny_>
from rom-o-matic
04:21
<Nubae>
another issue I've noticed on my low fat clients is I cannot log out
04:21
<johnny_>
with etherboot
04:21
Nubae, if you have autologin.. you cannot logout..
04:22
<Nubae>
its not autologin
04:22
<johnny_>
not sure if you are, just putting it out there for you in the future
04:22
<Nubae>
its a low fat client authenticating against ldap
04:22
but at least I have flash and java working now
04:46johnny_ has quit IRC
04:48

how do you know all this stuff? seems like there is a never ending stream of knowledge
04:51
<jamey_>
Would a server machine of the following specification be able to handle 36 LTSP thin clients without lag or delay? Intel Core 2 Quad Q6600, 16 GB DDR2-800 RAM, 1TB SATA RAID HDD, NVIDIA 7600GT graphics, dual Gigabit Ethernet, 700W modular PSU.
04:52bobby_C has joined #ltsp
04:52
<Nubae>
depends on what its running, flash... no
04:52
anything else yeah
04:52
<jamey_>
flash really kills it? what about video?
04:52
<ogra_cmpc>
Nubae, i'm working on ubuntu since it exists ... you grasp one or the other thing ;)
04:53
<Nubae>
if its via flash, it'll kill it too
04:53
<ogra_cmpc>
flash wont kill yousr server :)
04:53
<jamey_>
:D
04:53
Nubae: otherwise, what would you change from that spec to make it better for LTSP?
04:53
<ogra_cmpc>
the connection might get saturated but the server will surely cope
04:53
<Nubae>
sure it will, at least it does here
04:53
ok, yeah kill the server is the wrong word
04:54
<jamey_>
slowdown?
04:54
<Nubae>
use the processor to its maximum capacitry
04:54
<ogra_cmpc>
that server looks perfect, the flash lagging isnt a server performance thing
04:54
<jamey_>
what're you running over there?
04:54
<Nubae>
lot of ram
04:54
<jamey_>
oh okay well the intended environment is an office anyway
04:54
<Nubae>
u dont need 16 gigs of ram
04:54
<jamey_>
oh right, i thought it was 512 + 256 * 36
04:54
<ogra_cmpc>
you can surely make use of 16G :)
04:54
<jamey_>
which is like 9.5 GB
04:55
i thought so ogra :D
04:55
<ogra_cmpc>
jamey_, nah, we're not *that* mean yet
04:55
<jamey_>
so I thought it'd be best to "round up" to 16 GB from 9.5
04:55
<ogra_cmpc>
128M per running session
04:55
<jamey_>
ahh, well it's going to be an ubuntu LTSP server
04:55
does that make it heavier lol
04:55
<Nubae>
I run about 40 concurrent connections at any one time and never see the server go above 7 gigs
04:55
<ogra_cmpc>
+256 for the server to operate
04:55
<jamey_>
righty, so you both think 8 GB would be plenty?
04:55
<Nubae>
although I'm killing user sessions continously
04:55
<ogra_cmpc>
yeah
04:55
<jamey_>
then I can get a cheaper motherboard...
04:56
okay cool
04:56
<ogra_cmpc>
having another 8 might speed up disk access through better caching etc
04:56
<jamey_>
ah okay, well it's so cheap right now...
04:56
<Nubae>
yeah true it is
04:56
<ogra_cmpc>
so it surely makes sense and is future oriented :)
04:56
<Nubae>
if the motherboard can take it

yeah I haven't really researched it enough, most boards take only 8 GB unless you go gaming/server

yesterday my server almost collapsed after running 20 gnash sessions concurrently
04:58
i hate flash
04:58
<jamey_>
ew that's disgusting, can't there be a processing limit on gnash processes or something
04:58
<ogra_cmpc>
Nubae, well, gnash is still young it might have more memory leaks than firefox at the current state :)
04:59
<Nubae>
heh
04:59
yeah it spawns multiple processes per page
04:59
but its the only thing that runs youtube for me
04:59
<ogra_cmpc>
even though i heard it works with most videos nowadays
05:00
<Nubae>
yeah and it works on 64 bit
05:00
<ogra_cmpc>
i'm working on libflsahsupport ... flash should be fine by release as well

oh nice
05:03

its just a matter of time ... i need to find some to invest there :)

how can i umount usbdrive in clients by command?
09:21
<ogra_cmpc>
they are not mounted so you cant unmount them... just pull them out
09:21
<alumno10>
but if data get corrupted?
09:22
<ogra_cmpc>
the device is actually only mounted during read or write operations
09:22
two seconds afterthe last operation was done it gets transparently unmounted
09:22

wow, nice!

my clients have sis7019 sound hardware, which is not longer supported by kernel since 2.6.14 or so, then i found an usb sound adapters, do you think it could be the solution?

i've tried to compile module sources, and i got bad module format or so

I don't think the driver has ever made it into ubuntu repositories. I've tried many times to contact the author of the driver, but i've never gotten the permission to push the driver code upstream

I don't have it here right now. I'd have to dig into very old emails to find it
09:56
the problem is, SiS wrote the driver, and they said we could use it for whatever we want, but they haven't given "Official" permission. and that is what is needed for upstream inclusion
09:58
<alumno10>
when you have free time, could you pls find it , its kind of important, since im working in nice free basic computing learning center for childs, and we have like >30 clients with its sound hardware you know.

make the kernel build the oss stack and compile the module against that its a very hard task and you wont have fun with the result as i told you before the sound isnt usable even if you get the module running

not even 2second boing or pling sounds come through in one piece without stuttering

Hi folks. Where is your upstream vcs? I can't seem to find that info on any of the web pages...
10:43

10:48
bjorn, do you use etherboot anywhere ?
10:50
<bjorn>
ogra_cmpc: i don't use the etherboot package. i do (of course) boot my t5710 over the LAN, but that's using the lanboot support that's standard on the t5710
10:50
<ogra_cmpc>
is that PXE compatible ?
10:51
you could just mv /usr/sbin/mkelfImage /usr/sbin/mkelfImage,orig ...
10:51
the test in the script acts on: which /usr/sbin/mkelfImage
10:51
so if you rename it and remove the nbi image etherboot images should be skipped completely
10:51mhterres has joined #ltsp
10:53* sutula is still puzzled why he isn't seeing bjorn's issue on his t5710's...I seem to be using DRI (according to Xorg.log) and USB...but I have a meeting so will have to resume puzzling later
10:54
<bjorn>
sutula: you're not using aw's custom DSDT, are you? guess you must not, because you'd have to rebuild your ltsp kernel to do so. take a look at your /proc/interrupts and see if it has the VGA device in it
10:54* sutula looks
10:56
<ogra_cmpc>
you have to recompile to use a different dsdt ???

i think there is more use than developing in it :)
11:44
<bjorn>
ogra_cmpc, yes, but ultimately the firmware workaround should go in the OS, because a custom DSDT is not really supportable (IMHO)

i don't really understand the nbi thing. are you saying that nbi is only required by the etherboot pkg, and since i don't use that, all i need is the vmlinuz and initrd.img?
11:48
<ogra_cmpc>
nbo is an etherboot image
11:48
if your clients do etherboot they will ask for this one
11:48
<warren>
ogra_cmpc, meaning you have no job if you eliminate all bugs?

heh, yeah
11:51
<bjorn>
ogra_cmpc: my /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default edits do make a difference, so i infer that my client requests /ltsp/i386/pxelinux.0 rather than /ltsp/i386/nbi.img. so i guess that means i indeed don't need nbi.img

ogra, we wouldn't include it if it weren't GPL
12:27
I only did some cursory testing of this
12:27
no idea if it works
12:27
<ogra>
\it cant be gpl
12:27
it was never licensed by sis
12:28
<warren>
ogra, the sources that jim was pointing out earlier was a broken OSS driver
12:28
ogra, you mean that?
12:28
<ogra>
it will likkely work as well as the one for 2.6.16 that floats around on the ltsp wiki
12:28
<warren>
we don't ship any OSS at all
12:28
this is an ALSA driver
12:28
<ogra>
huh ?
12:28
<alumno10>
warren, in the web you wrote, it says that this sound hardware works in feisty
12:28
<warren>
we ship with OSS completely disabled
12:28
alumno10, web I wrote?
12:28
<ogra>
where did you get that ?
12:29
<warren>
ogra, upstream alsa
12:29

trhats not in alsa upstrem

ogra, i patched my kernel, ran "dch -i", and rebuilt with "fakeroot debian/rules binary-386", hoping it would build a linux-image-2.6.22-15-386 instead of linux-image-2.6.22-14-386. but it just built linux-image-2.6.22-14-386 again. what should i have done?
12:40
<ogra>
bjorn, no idea, i have compiled my last kernel about 4 years ago :)
12:40* ogra points bjorn to #ubuntu-kernel
12:41
<ogra>
there is nothing i cant do in the initramfs ... i havent seen a need for compiling a core kernel for years

at least since i use ubuntu

ogra, my bad; it *did* build a different .deb. similar enough that installing it replaces the previous, but that's good enough for now
12:54

yeah
12:54
it wont raise the API number in the package name, but the package version :)

ogra, edubuntu feisty comes with ltsp5 and sis7019 sound hardware support, right?
13:04
<warren>
alumno10, want to try Fedora 8? sis7019 might be working, and LTSP5 is almost complete there
13:04
alumno10, I need testers
13:05
<alumno10>
warren, I could do that but, now im working in a system used all day and i cannot make tests :/
13:05
<warren>
ok
13:05
<alumno10>
its a free basic computing learning center
13:06
thats why i need so much sis7019 support
13:07
i promised you that i'll test fedora 8
13:07
but in 1 or 2 more weeks

13:15
<alumno10>
ok, thanks
13:17
:o fedora 9 alpha =B~
13:17
<warren>
alumno10, LTSP5 is less capable there, working on that now
13:17
alumno10, you might have trouble with kernel or X not working in F9
13:19
<alumno10>
no, I could use f8 in works systems, but f9 just for curiosity :P
13:20
warren, what about k12? better than edubuntu?
13:20
<warren>
alumno10, no
13:20
alumno10, K12LTSP is based on fedora 6 and LTSP4
13:21
alumno10, K12Linux will be LTSP5 on Fedora 8+
13:21
<alumno10>
humm i see
13:22
i think i'll make tests with edubuntu feisty, since it supports sis7019 and comes with ltsp5
13:22
according to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/187879
13:23
warren, could you pls check this website, since english isn't my main language
13:23
I understood that feisty brings with sis7019 support
13:23
<warren>
alumno10, I have nothing to do wiht Ubuntu
13:23
alumno10, this bug is talking about the OSS driver for sis7019 which is known to be very broken
13:23
alumno10, Fedora 8 has the ALSA driver which is entirely different
13:24
<alumno10>
and fedora 8 comes with ltsp5 and sis7019 alsa drivers, right?
13:24
<warren>
alumno10, no
13:24
alumno10, LTSP5 is an add-on I'm working on, it 80% works now
13:24
alumno10, I still need to fix pulseaudio, but very close
13:24
<alumno10>
ok, thanks
13:25
<warren>
alumno10, sis7019 comes with Fedora 8 updates
13:25
<alumno10>
then to make sis7019 works i have to change alsa to oss, is that possible?
13:26
...in ltsp5, in lts.conf?
13:26
<warren>
alumno10, if you are asking about ubuntu, I have no idea.
13:27
<alumno10>
no, not specifically ubuntu, any distro with ltsp5
13:28
<warren>
alumno10, in Fedora the sound driver should automatically load
13:28
alumno10, but I haven't tested that yet
13:30
<alumno10>
ok, i might try fedora 8 today or in a near day, cause i have to solve this sound problem soon
13:33
<warren>
alumno10, LTSP5 isn't complete on Fedora yet, you WILL run into different problems
13:34

ogra, that actually isn't going to work either, because there are some legitimate non-UTF-8 locales

14:12
<mnemoc>
sutula: yes, but i'm still puzzled..
14:12
sutula: as those "tarballs" have architecture
14:12
sutula: and i'm looking for sources
14:13
<sutula>
mnemoc: The upstream is bazaar, on an Ubuntu page
14:13
<johnny>
no.. on a launchpad page :)
14:14
<warren>
hmm, ldm on Fedora 9 isn't happy
14:14
<sutula>
mnemoc: I suspect ltsp isn't usable without the distro hooks, so that's why there's no bare-bones tarball
14:14
<mnemoc>
sutula: i want to implement those hooks on the distribution build kit i use
14:14
sutula: but i don't know where to start :\
14:14

Q-FUNK, hmmm,... have you seen anything in the screen* scripts that causes the geode to fail to display anything on the monitor outside of running X?
14:20
curiously geode is the only thing that does this
14:20
<Q-FUNK>
hm?
14:20
come again?
14:21
<warren>
when screen scripts run here, it makes the monitor just stop displaying any text
14:21
I didn't even run X
14:21
<vs-adm>
alright, actually I have a problem with LTSP here: Xorg autodetects screen resolution incorrectly and monitor hangs. How can I set explicit resolution?
14:22
can't find any refs in documentation
14:22* warren gives up on geode for now, gotta work more on the core
14:22
<sutula>
vs-adm: Which distribution?
14:22

warren: do you use lxfb?

14:23

14:23
<Gadi>
lsmod |grep lxfb
14:23
<warren>
Gadi, no kernel framebuffer here at all
14:23
<Gadi>
ok, good
14:24
<sutula>
vs-adm: Does http://wiki.debian.org/LTSP/Howto help, or have you seen that
14:24* Gadi has found weirdness with the fb
14:24
<Gadi>
tho, you may want to load it and see what happens on ur box
14:24* sutula recalls some stuff about disabling autodetection stuff there
14:25
<warren>
never heard of lxfb
14:25
<Gadi>
vs-adm: X_MODE_0 = 1024x768
14:25
<warren>
not sure we have it
14:25
<Gadi>
warren: what kernel version?
14:25
<warren>
Gadi, 2.6.24+
14:25
Gadi, are you sure that's even in the upstream kernel? sounds like an add-on
14:25
<vs-adm>
sutula, yes, I used this howto to setup everything
14:26
<Gadi>
should be in the upstream kernel > 2.6.22
14:26
<vs-adm>
Gadi, is it? there is no such parameter in documentation
14:26
<Gadi>
vs-adm: depends on ur documentation :)
14:26
<sutula>
vs-adm: see Gadi's response...do you have an lts.conf?
14:26
<vs-adm>
Gadi, :)
14:26
sutula, shure

hmm, what launches cdpinger?

alright, sutula, Gadi 10x to you. I'll try such an option. )
