hi there, i want to use a thin client of HP ( supporting Citrix and RDP ) with LTSP, what do i need to do to get it working ?
05:37
I've setup Ubuntu server to support LTSP as described of the websites.

cliebow__: food is easy
10:23
lobster+beer == well fed
10:23
next question?
10:24
I figure lunch on saturday, we'll stop in Ellsworth on the way into SW.Harbor
10:25
maybe a quickie at wendys or McD's or something
10:25
then, dinner we'll get David.L to cook us up a wonderful dinner
10:36
<cliebow__>
Cool!! he is amenable??
10:37
the kOZY kOVE is uncertain..ill try to check that out
10:39
<jammcq>
I figure for dinner on sunday, maybe we'll get some pizzas from that place not too far from the Seawall. it was a party store directly west of the seawall
10:39
kind of around the block, but it's a big block

Some co-workers and I want to build a couple of sumobots and are researching controllers. The make boards definately has a lot of features, but does that make it a more complicated board to program?
11:24
Oops, wrong window. forgive me.
11:24
<vagrantc>

<jroberts>
I setup ltsp in my home a few years back, really loved it. At work recently I saw a use for it and decided to set up a server to get familiar with it again, it's really changed a lot.
11:28
<vagrantc>
hopefully mostly for the better :)
11:29
<sbalneav>
We've been working on it :)
11:30
<vagrantc>
sbalneav: any idea why LDM2 in etch doesn't display the background, but otherwise works ?
11:30
or more, what would cause that
11:30tux_440volt has joined #ltsp

<jroberts>
I setup an edubuntu lab environment in less than 30 min.
11:31
<sbalneav>
vagrantc: Well, it's the greeter itself that displays the background.
11:31
<jroberts>
pretty cool.
11:31
<vagrantc>
sbalneav: the other parts of the greeter work fine
11:31
<sbalneav>
one sec, I'll point you to the relevent lines.
11:32
<vagrantc>
this is going to force me to become semi-competant in reading C i suspect :)
11:32
<sbalneav>
Oh, by the way, now that things are slowing down a bit, I'm going to upgrade my etch box. Lenny's probably where I should be at?
11:32
<vagrantc>
sbalneav: lenny's the development environment
11:33
lately, i've been testing on lenny, and then when i get it to a reasonably good state, try to backport it to etch.
11:33
<sbalneav>
logo = gtk_image_new_from_file(PIXMAPS_DIR "/logo.png");
11:33
So, PIXMAPS_DIR needs to be set in the autoconf
11:33
rawpic = gdk_pixbuf_new_from_file_at_scale(PIXMAPS_DIR "/bg.png", pw, ph, FALSE, NULL);
11:34
<vagrantc>
so, what would cause that to work when compiled for lenny, but fail when compiled for etch ?
11:34
<sbalneav>
And that's the background
11:34
<vagrantc>
and actually, if i install the packages compiled for etch on lenny, it works.
11:34
<sbalneav>
Well, good question.
11:34
<vagrantc>
just get a blank white screen
11:34MagicStorm has quit IRC
11:34
<sbalneav>
One of two things:
11:35
Either the PIXMAPS_DIR macro isn't being set for some reason, or...
11:35
gdk_pixbuf_new_from_file_at_scale() is broken for some strange reason.
11:35
Not a perm problem, is it?
11:35
<vagrantc>
permissions ?
11:35
<sbalneav>
Shouldn't be, since the greeter runs as root.
11:35
<vagrantc>
right
11:35
<sbalneav>
hm.
11:36
<vagrantc>
and the permissions when installed on etch are the same when installed on lenny
11:36
<sbalneav>
right.
11:36
You can just run the greeter standalone on the server.
11:36
Try putting all the pixmap stuff up on the server, then just run ldmgtkgreet
11:37
You should be able to alt tab between it and the terminal you start it from
11:37
<vagrantc>
two main difficulties with the etch backport... X.org in etch isn't good enough at autoconfiguring itself... but i've enabled a way to use the old method ... and LDM doesn't display the background...
11:37
<sbalneav>
You can actually interact with the greeter: send it the commands it needs, and read it's responses.
11:37
<vagrantc>
really...
11:37
<sbalneav>
maybe it'll issue a GTK error complaining about the image.
11:37
yeah, it just reads/writes stdio
11:37
<vagrantc>
should i be able to see that in the ldm.log ?
11:38
<sbalneav>
Hmmm, I don't thing I'm trapping stderr, and piping it anywhere. I probably should.
11:38
<vagrantc>
if i recall correctly, i don't see anything
11:38
<sbalneav>
I'd have to connect stderr to the logfile, with dup() or some such.
11:39
<vagrantc>
oh, regarding lenny, the 5.0.3?* packages haven't actually made it to lenny yet ... waiting for other dependencies to get into lenny
11:39
<sbalneav>
OK.
11:39
Well, I should move to lenny anyway on the deb box.
11:40
<vagrantc>
but i've tested the newer ltsp stuff with lenny and it appears to be working
11:40
got a boatload of translations pending :)
11:41
latest addition is a complete finnish translation
11:44
<sbalneav>
We'll want to make the translations part of upstream, you'll have to show me how that whole i18n thing works.
11:44
I'm completely clueless when it comes to i18n. I need a i18n for dummies book :)

11:45Amaranth has quit IRC
11:45
<vagrantc>
sbalneav: it's pretty simple for shell scripts ... not sure how it works for C programs
11:46
ogra: as far as i can tell, you have german translations for LDM, but they do not actually get built or installed ... ?
11:46exodos has quit IRC
11:47
<vagrantc>
sbalneav: basically, anywhere you would normally put a string ... say ... echo "foo bar" ... instead you would put echo "`eval_gettext "foo bar"`"
11:47Amaranth has joined #ltsp
11:48
<vagrantc>
sbalneav: and then at build time, make looks through all your shell scripts, pulls out the translateable strings, and compiles the language-stuff
11:51
i think for C, it's actually a little more elegant
11:52
<rjune_>
it's actually fairly similar based on what I've seen

sbalneav: i've got some commitments here till mid-november
12:17
till the 11th, at least
12:18
<sbalneav>
Too bad. I'll miss you
12:18
<vagrantc>
yeah.
12:19
i'd really like to hang out and figure out some of the upstream stuff
12:20
sbalneav: i think you should get to meet stratus at the UDS, though. he's been one of the debian LTSP folks
12:22
<sbalneav>
Ah, cool
12:22
Well, hang around online
12:23
We'll ask plenty of questions
12:23
<vagrantc>
heh :)
12:24cyberorg has joined #ltsp

<vagrantc>
main things i want to work on are getting ldm split into it's own source package... right now it's holding the rest of ltsp from progressing from unstable to testing in debian
12:26
and getting some theme packages
12:27
so that all architectures don't have to duplicate all the .png files, and to make it easier for other CDDs to drop in their themes.
12:27
(CDD = custom debian distribution)

<^Migs^>
when I'm running a graphic-intensive application off an LTSP server, do all the thin clients need graphics cards capable of running the app, or is it only the server that does?
17:23
I hope that's not a dumb question

<rjune_>
^Migs^: any terminal that will run the graphical program
17:46
<^Migs^>
so if I'm trying to run something that requires, e.g., Pixel Shader 2.0, the client needs an adequate graphics card?
17:46
I'm not sure what you meant by any terminal that will run the graphical program
18:03
<sbalneav>
^Migs^: Even with a good graphics card, you'll probably find that performance on a thin client will be much slower.
18:03
Simply because all the graphical operations are now going to be tunnelled over the network.
18:04
So, at a bare minimum, you're going to want gigabit networking.
18:04
<^Migs^>
okay, I was expecting to use gbit anyway. Still hasn't answered my question. Does the server's graphics card handle all the graphics processing, or does the client's?
18:05
<sbalneav>
The clients
18:05
<^Migs^>
okay
18:05
thank you
18:05
crap
18:06
I was wanting to install some applications like Celestia (www.shatters.net/celestia) or Alice (www.alice.org) in a school lab, but might be harder with that restriction
18:07
<sbalneav>
Well, instead of celestia, you can use kstars, which will work fine on a thin client.
18:08
<^Migs^>
kstars sucks
18:09
it's not even remotely comparable
18:09
you can travel through the entire universe with Celestia. Not so with kstars.
18:10
<sbalneav>
I wouldn't say it sucks, as I use it all the time for my amateur astronomy, but to each his own.
18:10
<^Migs^>
my opinions are always correct
18:10
<sbalneav>
uhh, yeah.

pabluss: you are asking a WINDOWS question in a Linux forum. you aren't likely to get much response
20:31
<pabluss>
jammcq: no, because severals years ago i did it but nfs + etherboot in a Sun Solaris Server, now reading ltsp i think that is possible.... i don't know if there is some experience for this...
20:31
jammcq: the windows flavor was windows 3.11 , now i don't know if it's possible with xp ..
20:32
<jammcq>
pabluss: I'll remind you the 'L' in LTSP stands for Linux
20:32
we don't do windows here
20:33
<pabluss>
jammcq: but --> http://wiki.ltsp.org/twiki/bin/view/Ltsp/WinIntegration ?
20:33
the idea is the same..
20:35
<jammcq>
that's not booting windows as diskless
20:35
that's using rdesktop to access a windows terminal server
20:35
<pabluss>
