<WITRChris>
so how important is a graphics card in an LTSP server?
12:42
if I'm looking to set up a set of about ~30 nodes, should I go for a workstation-level graphics card?
12:42
the nodes will all be mostly running the same software
12:42
<muppis_N900>
Well, just to get a machine to boot. :)
12:43muppis_N900 is now known as muppis
12:43
<WITRChris>
for the server, i should add.
12:44
<muppis>
Workstations/clients graphics is more importanta.
12:44
-a
12:49
<WITRChris>
hm really?
12:49
so the server doesn't render the graphics on its GPU or anything (that's what i expected)
12:50
<elias_a>
It does not work that way.
12:52
<muppis>
So, if you need GPU for the software, afaik, you need to run it locally in client.
12:53
<WITRChris>
ok
12:53
so we have software that requires NVIDIA openGL libraries (don't ask)
12:53
so I wonder if we need to run that locally...
12:54
<muppis>
Most likely.
12:58Phantomas has left IRC (Phantomas!~Phantomas@unaffiliated/phantomas, Ping timeout: 248 seconds)
13:04
<||cw>
well, all graphics will render locally, but very little has the ability to use client acceleration for a process running on the server
13:05
if you're using 3d graphic stuff, you'll probably want thick clients

Anyone here familiar with Centrify for AD connectivity? I have ubuntu 10.10 working with centrify, I can login to the server with AD credentials, but when I try those same credentials from a thin client it fails with userID not found.

<mesutcan>
hello
17:42
i have some questions about ltsp
17:42
i have a server which has 3GB ram
17:42
there are 10 thin clients
17:43
can we run KDE on that clients
17:43
KDE 4.8
17:43
and also clients may run a browser and an office program
17:43
or should i choose another Desktop Environment?
17:44
<dead_inside>
thats not very much ram, i would recommend something more lightweight like xfce

17:45erc has left IRC (erc!~erc@cable-129-134-156.b2b2c.ca)
17:47
<mesutcan>
hm, xfce or lxde?
17:47
which one is better or stable?
17:47
that clients must be stable
17:50
<dead_inside>
i have not played with lxde so i can not compare the two
17:51
but i have used xfce before and its stable enough for production environments
17:55
<mesutcan>
how much ram uses xfce?
17:55
also i'm using smem to check who uses how much mem
17:55
which information is right i'm not quite sure
18:02
<dead_inside>
top usually does a good job
18:03
really it depends on the end user, and how much crap they have open at one time
18:03
<mesutcan>
i will optimize the system
18:04
they can open a browser and a office suite

18:07
<mesutcan>
nothing more
18:07
i wonder with a browser and xfce how much memory uses
18:07
more than 300?
18:08
and which browser should i prefer?
18:08
with xfce is midori OK?
18:08
and a office suite
18:08
any other possibilities than libreoffice

Anyone here a developer for the LTSP project on EL6?
19:25* vagrantc doubts it
19:26
<Enslaver>
Where would they be?
19:26
<vagrantc>
lost to time, it seems
19:26
haven't seen much activity from the fedora/redhat crowd lately :(
19:26
<Enslaver>
Thats what i'm here to talk about
19:27
I'd like to take it over if its dead
19:27
<vagrantc>
ah, cool!
19:27
<Enslaver>
I'm the main LTSP developer for my company running over 100 thin clients on EL6 using LTSP 5
19:27
<vagrantc>
i mean, i'm partial to debian, and ubuntu's pretty active, and opensuse has their kiwi-ltsp thing ... but theere was a time where we had a really healthy cross-distro community
19:28
<Enslaver>
I see the cross distro support, getting more and more incorporated as i download the daily trunks since 2010 but it seems EL6 development fell off around then
19:29
8/12/2011 was the last update from k12linux on fedorahosted
19:29
<vagrantc>
yeah, i know warren togami has been working on other things and wanted more help from the community at large

19:30
<Enslaver>
If you can get me in touch with the right people I can pick up where they left off, i've already been able to get sound, remote/local apps, usb and scanning working on EL6
19:30
<vagrantc>
Enslaver: i'd recommend subscribing and posting to ltsp-discuss@lists.sourceforge.net about your interest
19:32
i don't really know fedora or redhat communities well- the only one i knew was warren togami and he was pretty frustrated with the situation
19:32
but there are lots of people in the community who are interested- so if there's someone too tackle the work, great :)
19:32
<Enslaver>
Do you have a contact for him?

19:32

if not i can google him im sure
19:33
<vagrantc>
Enslaver: he should be pretty findable, i'm guessing
19:33
<Enslaver>
yah just found him
19:33
first@last.com email, lmao
19:34
<vagrantc>
anyways, gotta run, hope to hear more later :)
19:34

For sure thanks for your help

20:14mikec has joined IRC (mikec!~mikec@stat5test.stat.wisc.edu)

<mikec>
In the ltsp cluster environment, is there usually a common reason why a log in attempt results in "No response from server, restarting"?
20:22
<||cw>
firewall, routing, dns, services locked up
20:22
<dead_inside>
mikec usualy your ssh keys are wrong
20:26
<markit>
mesutcan: I use kde, my considerations are: a) in Thin client setup, if one runs a program the memory is occupied only once for the code, the rest is data, so if you run firefox on kde or xfce the problem is the same
20:26
b) memory is cheap, expand it to a reasonable amount of ram!
20:27
d) expand client's ram and set it up as Fat client, so if you add more (fat) clients it scales up well
20:27
c) I've missed c :)
20:27
<muppis>

20:38
<mesutcan>
markit, yes, but we tried to run 5 clients on that server and it ran out of memory
20:39
unfortunately we can't expand ram amount
20:39
for servers
20:39
and clients
20:41
markit, did i understand correctly? A firefox is occupying the memory and every client uses them?
20:41
for my scenario it didn't work since 5 client can use 3gigabyte ram
20:44
<markit>
mesutcan: the program code is loaded only once, the memory it allocates for user's data no, of course, as far as I understand
20:44
or at least libraries are shared
20:44
I mean, you can't cound how much ram a single user uses, and then multiply for the number or users
20:45
I think kde occupies 1GB of ram, let's put each user uses 200MB -> 3GB
20:46litlebuda has joined IRC (litlebuda!~litlebuda@204.0.166.178.rev.vodafone.pt)
20:46
<markit>
I think that lxde occupes less, let's say 500MB
20:46
but you save ONLY 500MB
20:46
not 500 x 10
20:47
mesutcan: in short, you have no alternative than reduce the clients or add ram
