Guys, where I can found jetpipe source?
Q-FUNK: an lp_server replacement
IRCzito, its suposed to move into its own source tree at some point, for now it sits somewhere in the ltsp source
ogra: ow, thanks :D
herson, thats ancient :)
thats jetpipe: http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/annotate/vagrant%40freegeek.org-20080411163710-enx278andfudnhwn?file_id=jetpipe-20061206173433-pmrfiu61j4wm2itf-2
ogra: wath script launch jetpipe on the client?
i see in your page
(you will notice it didnt change much though :))
the configure_printer function in that initscript

darn X. DDC is broken again on amd/geode and, even worse, it fails to support any other resolution than the default 800x600. yet, this driver can give impossibly large resolutions if compiled against an older X core.
|07:16||* ogra wondes where all these scary baslashes come from|
Q-FUNK, but thats ony autodetection, right ?
ogra: thanks :D
if i hardcode resolutions it will work
ogra: no, even specifying the resolution in xorg.conf fails. X insists on reporting bad freq ratio that it cannot use
i thought the -geode upload fixes the world :/
well, it again seems that this ix x core related.
that x86emu is such a piece of crap!
did the former -amd work better with that ?
well, that's the funny part: amd 18.104.22.168 worked fine until a few days ago. now, even that one fails at DDC.
so this really points at an X.org core issue
and as it so happens, xserver-xorg-core was indeed updated during the last few days
heck, even 22.214.171.124 no longer detects the optimal rez

stgraber, hi, are you here?
hmm irgendwie ist eine Y kuppllung nich so prickelnd wenn man den kopfhörer leise stellen kann .. der zieht die ganze anlage mit runter
K_O-Gnom: wrong channel? :)
laga: nö die y kupplung hängt an der gentoo maschine :-P
ogra: yes, but a patch in x core, once again
Q-FUNK, right, i just want to know if we could avoid breaking it with the sync
laga: hmm yes wrong chang :-/
i can point bryce to look at the patch if i know which one breaks it
laga: got to many chans opened ... thougt here was #gentoo-anfenger
ogra: the sync won't chnage a thing. the problem is not the amd/geode driver.
Q-FUNK, the sync will change that people try the driver and will complain
ogra: there's alreayd reports of -amd no longer working with DDC
so it won't chnage anything with that either
so being able to identify whats broken in advance would help
whatever crappy patch broke it in x core already made its damage
(and probably having a chance to fix it during this week)
whether we sync geode in or not won't magically revert X core to the last known good
right, i'd like to rule out the "whatever" from your above sentence :)
ogra: me too, except that I have no idea which of those patches did it. i just know that 188.8.131.52-1 has been working fine until now and the onyl chnage that occured were new xerver-xorg-core uploads.
stgraber, hi again. In demo mode=on, on LTSP clients, the screen refresh is way too slow. I have to wait about 5 seconds for all the clients to see the next screen while showing a presentation. Is this normal?
stgraber: Even on one client it is very slow. It's not a network problem, I can watch videos in my client with 30 fps!!!
stgraber: with iftop, I can see the bandwidth going to > 30Mbps, with a single powerpoint presentation, on a single client... Can I do something to make it better?
alkisg: it's not "normal" but probably not italc's fault ... Possible things that cause that are : compiz (visual effects), network (VNC is far from being perfect), CPU usage for LZO compression
compiz: off, cpu: <10%
LDM_DIRECTX=True (no compression)
what else can I try?
I'm using the script you gave me, the broadcasting is at 127.0.0.1
alkisg: I don't think you can do much to fix that :(
OK... can I ask you something else? I'm willing to try to implement something like italc but for ltsp only,
alkisg: currently both clients and masters of iTalc are running on the server, then the client simply see it as a standard app
alkisg: a possible fix would be to run ica directly on the clients
so shared memory on the server to share the screens (viewing/broadcasting), and a little program on the client to show the received screen on demo mode
alkisg: but then you'd loose the ability of starting apps on the clients (but would have shutdown/reboot working)
No vnc code at all. Do you thing it would be too hard?
(thanks for the ica tip, I'll try it)
AFAIK all current solutions are based on VNC because that kind of apps are far from easy to write ... you need the part recording your desktop, compress, send and display on the clients ...
That's the thing, all clients run on the server, so no network should be involved
some bigs LTSP network are currently having a look at using iTalc so I guess we can expect some major changes for it
alkisg: VNC would probably use less bandwidth if ica was running on the clients instead of the server using the X tunnel
alkisg: because VNC traffic is compressed for that kind of use while X one isn't (or is less efficient)
last I spoke with the Millexterm guys about it, the idea was clearly to have ica/italc running as local app instead of running on the server
and they are running some really really big LTSP networks
stgraber: ok... can I try something else? As I understand it, ica uses vnc code. Is there any way to pass parameters to the vnc server/client, e.g. no compression?
alkisg: not that I know of, you'll have to change ica's code for that. X11VNC is directly used by italc's code and not run as a standalone app
I'm not optimistic about VNC, I've never watched video with good quality with it, on any OS/configuration. But X server shows 30fps with 30Mbps bandwidth, so with a good switch I can broadcast video to all my 12 clients...
I'll try to come up with another solution for broadcasting, maybe vlc/utp multicast. I tried it with one client and it was very promising.
iTalc is perfect for viewing/controlling/running apps/etc though.
VNC is completely different from the X server, VNC is broadcasting a video of your screen while the X tunnel is sending X events/window the rendering being done on the client
|08:09||ogra has quit IRC|
I see... that's why X behaves better, there's no screen grabbing involved.
Would it be possible to modify italc to grab the screen locally, without network involvment?
I mean, ask the X server that runs for the user12 to send the screen through a pipe or something
Capture events etc. Would it be a huge change, or something that I could do within a month?
italc is a multiplatform tool so I guess it'll always use VNC, there is still much to do to improve VNC's performance though
stgraber, thank you very much.

nothing, just spying here ;) Now you spotted me and I had to speak in here the first time, grr ;p
you gentoo guys sure overuse :p
it is meaningless now
well i'll try to convince you to test something after tuesday night :)
use it so much it loses all meaning and intent
i gotta script etc-update so it will automatically merge after openrc install to stop one extra step
since we won't see it in a stage3 til 2008.1
wasn't there a "merge all" negative number responas?
you mean ltsp5 will require openrc?
|18:00||rjune has left #ltsp|
either that or completely overwrite some baselayout 1 scripts
i figured it'd be better to go with openrc tho, since it is the futre

hello wondering if anyone has time to answer a question
gotta ask it first
things are working great on a ltsp 4.2 install.
johnny_: sounds good. Hopefully soon I'll get to upgrading to that as well, still at baselayout2_rc6 or so
if the internet is down then the thin
clients do not get
sorry.. no knowledge of ltsp 4.2 here
a gdm screen just a gray screen
or any ltsp 4 :(
ltsp5 doesn't use gdm
and that is all i know
if I plug in the internet again they all work
i bet each machine's /etc/hosts does not include the own machine's name
that's the only time i've seen that happen
but the server,
the only one that even
has a harddrive
sure.. they still have an /etc/hosts tho..
on the nfs root
it gets mounted somehow so it is readwrite
some sort of bind mount
but i'm not sure of the mechanism on ltsp4
you should come here during europe usa weekday daytime hours
thanks I will try and disconnect again to see about setting the hosts file /opt/ltsp/i386/etc/hosts
