<sbalneav>
Well, good news. Got the first succesful auth under libpam_sshauth.
04:10
<jammcq>
Scotty !!!!!!!!!!!!!!!!!!!!!!!
04:10
<sbalneav>
jammcq: hey ho.
04:10
<jammcq>
hidy how
04:11* vagrantc cheers sbalneav on!
04:11
<sbalneav>
Gettin' somewhere. Did that fix I came up with yesterday for LDM help alkis?
04:11
vagrantc: hey ho!
04:11
vagrantc: minor bug found in libpam_sshauth.
04:12
<vagrantc>
sbalneav: i didn't get a chance to test your LDM fix, but it built from source, at least :)
04:12
sbalneav: oh?
04:12
sbalneav: in the 0.1 or 0.2 generation?
04:13
<sbalneav>
0.2
04:13
rev's 75, 76, and 77
04:13
75: .h file not being included in make dist
04:13
76: improvements to debugging
04:13
77: non-return on value :( Fixed.
04:14
<vagrantc>
i don't think i used "make dist" anyways.
04:15* vagrantc can't even remember
04:15
<vagrantc>
it wouldn't have built from source if it didn't have that, would it?
04:17
<sbalneav>
Well, if you built from bzr source, yes.
04:17
But if you do a "make dist", to get a libpam-sshauth.0.2.tar.gz file, then the .h wasn't included.
04:18
<vagrantc>
sbalneav: there are automated builds from the debian source package, which has no idea that bzr exists.
04:18
https://buildd.debian.org/status/package.php?p=libpam-sshauth&suite=experimental
04:18
<sbalneav>
How did you produce the original *.tar.gz file? From bzr?
04:18
<vagrantc>
probably.
04:18
<sbalneav>
So that was fine.
04:19
<vagrantc>
i've got a script i use to generate tarballs from bzr and git ...
04:19
it's pretty braindead
04:19
probably used that
04:20
20:13 < sbalneav> 77: non-return on value :( Fixed.
04:21
that seems pretty important, though
04:21
<sbalneav>
Yup.
04:23
<vagrantc>
could roll a 0.2.1 tomorrow, or just patch the 0.2 version...
04:23
sbalneav: is it worth having updated versions in debian experimental yet?
04:26
<sbalneav>
Can we wait 'till after the hack-a-thon? That way, if we uncover anything, we can get a "good" version there.
04:28
<vagrantc>
sbalneav: works for me.
04:28
sbalneav: weren't you the one who asked for it to hit experimental in the first place? :)
04:31
<sbalneav>
Probably. I just wanted people to have an easy way to install the package.

<alkisg>
04:11<sbalneav> Gettin' somewhere. Did that fix I came up with yesterday for LDM help alkis? ==> what fix?
04:47
AFAIK ldm-trunk now is the same as when the bug appeared....
04:47
(hi all btw)
04:48
<vagrantc>
alkisg: i.e. it didn't make it worse?
04:49
<alkisg>
vagrantc: err no, it didn't make it worse, but we don't have any code in LDM yet that tries to address the bug...
04:49
We either need to kill all user processes,
04:49
or keep the ssh connection up until after xorg dies
04:50
I was waiting for sbalneav to help with the second solution, but if that's too hard and we give up on it,
04:50
<vagrantc>
but doesn't it provide a place to put the hook to kill the user processes?
04:50
<alkisg>
then we'll have to resort to the first one...
04:50
We always had such a hook
04:50
But killing all the user processes, and thus losing unsaved data, sounds pretty bad
04:53
<jammcq>
my understanding is that LDM will now catch the TERM/QUIT/... signals and run the rc files with 'stop' as the argument
04:53
and also do that on logout
04:54
BEFORE shutting down the ssh connection
04:54
<alkisg>
jammcq: yeah that was the same when the bug appeared
04:54
I removed the rcfiles("stop") call trying to fix that
04:54
I didn't; but putting it back doesn't make it any better either
04:55
<jammcq>
but ldm didn't used to catch the signals, it would just die
04:55
now it doesn't die until after the rcfiles are run
04:55
isnt' that better?

<markit>
hi alkisg, quick question, I've tested swappines set to 20 on my netbook and I have to admit that works much better. What about set the same in chroot for fat clients? Isn't a good idea?
13:17
<alkisg>
markit: if it's the same on netbooks and fat clients etc, why not try to convince the ubuntu or the kernel folks to change the defaults? :)
13:17
How do you measure the "it goes much better" part?
13:18
<markit>
alkisg: netbook has ked and 1Gb ram, with normal swappiness swaps like a mad
13:18
<alkisg>
It swaps?
13:18
I thought swapping only occured on special occations...
13:18
<markit>
you open firefox and a different program, then when you go from one to the other hd light works like a mad
13:18
<alkisg>
And with swappiness = 20 it doesn't?
13:19
<markit>
no, I can switch program much faster and without hd working like a mad
13:19
<alkisg>
And how do thin clients behave with swappiness = 20?
13:19
E.g. say with 128 mb ram?
13:20
Or, fat clients with 512 ram?
13:20
<markit>
vm.swappiness = 10
13:20
<alkisg>
Do those benefit from low swappiness? Or it makes it worse for them?
13:20
<markit>
as far as I understand, if you set to 0 it avoids swap, so probably system will crash
13:20
<alkisg>
What I'm asking is, suppose you have a fat client with 512 ram
13:21
Will it work better with swappiness = 20 or = 50?
13:21
<markit>
otherwise you say to the system not to to try to guess about not often used memory
13:21
<alkisg>
And, the same question about a thin client with 128 MB RAM
13:21
<markit>
I think will work better in any case
13:21
<alkisg>
Then why isn't 20 the default?
13:22
(from the kernel team, not from ubuntu...)
13:22
<markit>
with low ram what reasonable optimization could even do kernel with default swappines?
13:22
well, googling seems that is not set for desktop usage
13:22
<alkisg>
I don't know, but I don't like changing the defaults without specific and reproducible benchmarks...
13:23
It should be easy to introduce a SWAPPINESS lts.conf directive of course..
13:23
bbiab, gotta feed the little one...
13:24
<markit>
:)
13:24
http://en.wikipedia.org/wiki/Swappiness
13:24
and for most desktop systems, setting it to 100 may affect the overall performance, whereas setting it lower (even 0) may improve interactivity (by decreasing response latency.)

<alkisg>
markit: it just seems strange to me, when I install a desktop system, to not get a good value for swappiness
13:53
All those kernel folks, both upstream and in the ubuntu team, didn't see that?
13:55komunista has left IRC (komunista!~slavko@87.244.209.121, Ping timeout: 252 seconds)
14:02
<markit>
alkisg: I'm short of ram in my desktop too (4 GB, firefox eats a lot of ram, so do KVM if I run a VM with audio on, etc.) and I've set swappiness to 10 here too, and seems better
14:04
<alkisg>
https://help.ubuntu.com/community/SwapFaq#What_is_swappiness_and_how_do_I_change_it.3F
14:04
The default setting in Ubuntu is swappiness=60. Reducing the default value of swappiness will probably improve overall performance for a typical Ubuntu desktop installation. A value of swappiness=10 is recommended, but feel free to experiment. Note: Ubuntu server installations have different performance requirements to desktop systems, and the default value of 60 is likely more suitable.
14:05
That paragraph supports your findings
14:05
But then, why doesn't "ubuntu-desktop" change its value?
14:05
<markit>
this remembers me some scheduler war...
14:06
desktop had some benefit with scheduler A, but scheduler B was choosen for "better overall performances"
14:06
even if trashed your desktop
14:06
;P
14:06
maybe we could try to find a debian dev that has the answer
14:07
or will just reply "change it if you want a different value"
14:07
<alkisg>
I think a question in askubuntu could help
14:07
Or a bug report/question in the ubuntu kernel
14:08
<markit>
I asked you because maybe you already tried and found problems, so wanted to avoid do a mistake
14:09* markit fighting with the reinstallation of an unsupported epson scanner and epson printer... I do hate epson
14:09
<markit>
ops, canon printer
14:09
I do hate canon as well ;P

alkis: dunno if you're busy, but if you get a chance I got the xorg.7.log file.. http://pastebin.com/3Cki11V7 ..and am still having problems the thin client display coming up as scrambled or saying "input not supported"
18:04
I tried to troubleshoot for a few hours last night but don't think I really got anywhere
18:09
it does work when using a 25 pin monitor cable and dvi adapter, but only if it is the only one plugged in, and it scrambles with one dvi cable plugged in to the dvi-i, and nothing (input not supported) just the dvi-d or both are plugged in
18:19
<Enslaver>
So is this not right? I have a plugin for the ltsp-build-client, add_option "fat-client" "`eval_gettext "run most or all applications locally"`" "advanced" "false"
18:19
meaning no param, but I'm checking for it with: if [ -n "$option_fat_client_value" ]; then
18:19
but its failing the test

sbalneav: hi, so, we're giving up on the "keep the SSH connection alive after X dies" idea, right? Should I just go ahead and kill all user processes using something like this? http://paste.ubuntu.com/5562463/
18:40
<kev_n>
I just checked with ddcprobe and edid does fail... so I assume that means I need to put the info in the xorg.conf in the chroot?
18:41
<alkisg>
kev_n: the best idea is to troubleshoot the graphics problems without LTSP (e.g. with the help of the people over at #ubuntu-x), and, once you know what to do, then come here and ask for help on how to do it via lts.conf
18:41
The openchrome driver is pretty buggy
18:41
If the problem is horzsync and vrefresh, put something like these in lts.conf:
18:42
X_HORZSYNC=33.0-61.0
18:42
X_VERTREFRESH=33.0-61.0
18:42
<kev_n>
alkisg: I kinda got that impression when I was doing a search on the dvi center is disabled issues
18:42
<alkisg>
Scratch the first one, it's wrong, I meant this one: X_HORZSYNC=33.0-87.0
18:42
<kev_n>
does that mean I would need to disable xrandr or is that only for x_mode?
18:43
<alkisg>
That's instead of EDID, you can still use xrandr
18:43
<kev_n>
ok
18:43
<alkisg>
Actually, try with only those 2, nothing else in lts.conf

So I just checked on the shell of the client and I use 'dpkg -l | grep openchrome' but nothing shows.. but when I check on the server and on the server with ltsp-chroot it does.. could that be part of the problem?
