[01:34] <alkisg> Unfinished description at https://blueprints.launchpad.net/ubuntu/+spec/packageselection-edubuntu-n-seed-review
[01:38] <stgraber> hmm, indeed, fixed.
[01:42] <highvolt1ge> heh
[04:27] <mhall119> highvoltage: have you had a chance to do anything with debmower?
[13:55] <highvoltage> mhall119: yep, worked on it a bit on Friday, busy implementing the LXC parts that will isolate everything from the host, not completed yet but it's happening :)
[17:46] <Firemouth> hello
[17:46] <Firemouth> i'm having some performance problems with client computers using edubuntu
[17:47] <Firemouth> i have two identical laptops, one is the server and one is booting off the network
[17:47] <Firemouth> im trying to use Tux Typing
[17:47] <Firemouth> it works fine on the server laptop
[17:47] <Firemouth> but its a slide show on the client
[17:48] <Firemouth> anyone have any suggestions on how to improve the performace on the client laptop?
[18:26] <Firemouth> maybe a step in the right direction... i verified the server is connected at 100mbits
[18:26] <Firemouth> is there a way i can check to see what speed the client is connected to the network?
[18:27] <Firemouth> it _should_ be connected at the same speed being the same hardware but i'd like to verify it so i can eliminate that as being a source of the problem
[18:31] <alkisg> Firemouth: are you using LTSP?
[18:31] <Firemouth> yes
[18:31] <alkisg> Do you have LDM_DIRECTX=True in lts.conf?
[18:31] <Firemouth> i do not know, i will check, do you know where i'd find that file to save me some time looking for it? :)
[18:32] <alkisg> Sure, do this:
[18:32] <alkisg> sudo gedit /var/lib/tftpboot/ltsp/i386/lts.conf
[18:32] <alkisg> And put the following into that file, if it's empty:
[18:32] <alkisg> [Default]
[18:32] <alkisg> LDM_DIRECTX=True
[18:32] <alkisg> Then reboot the client, you should see great improvement.
[18:32] <alkisg> BUT there's a security cost, so after trying it, go and read the ltsp docs
[18:33] <Firemouth> its a local lan so security isn't a concern
[18:33] <Firemouth> k got it in there, rebooting client
[18:35] <Firemouth> hmm
[18:35] <Firemouth> not seeing any improvement
[18:35] <Firemouth> do i need to reboot anything on the server?
[18:35] <Firemouth> i did a full reboot of the client
[18:36] <alkisg> Just the client
[18:36] <Firemouth> hm
[18:36] <alkisg> On the client, open a gnome terminal
[18:36] <alkisg> There, run this command: ltsp-localapps xterm
[18:36] <alkisg> An xterm will open
[18:36] <alkisg> On that xterm, run this command: getltscfg -a
[18:36] <alkisg> And paste the contents
[18:37] <Firemouth> says its not currently installed
[18:37] <alkisg> You missed something
[18:37] <alkisg> Did an xterm open?
[18:37] <Firemouth> sorry i must be missing something
[18:38] <Firemouth> i did Applications -> Accessories -> Terminal
[18:38] <Firemouth> are you looking for something different?
[18:38] <Firemouth> oh crap
[18:38] <Firemouth> i missed a step, sorry
[18:38] <alkisg> :)
[18:38] <Firemouth> ok
[18:38] <Firemouth> got the xterm jup
[18:38] <Firemouth> up*
[18:39] <alkisg> That's called a "local xterm". Run that `getltscfg -a` command there.
[18:39] <Firemouth> LDM_DIRECTX="True"
[18:39] <Firemouth> export LDM_DIRECTX
[18:39] <alkisg> OK. Continue with: lspci -nn -k | grep -A 2 VGA
[18:41] <Firemouth> 01:00.0 VGA compatible controller [0300]: nVidia Corporation G72M [GeForce Go 7400] [10de:01d8] (reva1)
[18:41] <Firemouth> Subsystem: Sony Corporation Device [104d:81e6]
[18:41] <Firemouth> Kernel driver in use: nouveau
[18:42] <alkisg> OK, I don't see anything bad there
[18:42] <Firemouth> is there a way to confirm the client is connected @ 100mbits ?
[18:42] <alkisg> E.g. you should be able to watch full screen video with no lost frames
[18:42] <alkisg> Sure, with the ip command
[18:42] <alkisg> Let me find the exact syntax...
[18:43] <alkisg> (so that you don't have to install ethtool...)
[18:43] <Firemouth> oh
[18:43] <Firemouth> already installed it
[18:43] <alkisg> In the chroot?
[18:43] <Firemouth> not sure, i did sudo apt-get install ethtool on the server
[18:43] <alkisg> Then nope :)
[18:43] <Firemouth> hehe k
[18:48] <alkisg> Hmmm more difficult than I thought :D
[18:48] <alkisg> OK, try this:
[18:48] <Firemouth> yeah i was playing with it, not getting anywhere
[18:48] <alkisg> Open lts.conf again, and add this at its bottom:
[18:48] <Firemouth> k
[18:48] <alkisg> SCREEN_02=shell
[18:48] <alkisg> Reboot the client.
[18:48] <alkisg> When it boots, press alt+ctrl+f2
[18:48] <alkisg> There, run: apt-get install ethtool
[18:48] <alkisg> And then: ethtool eth0
[18:49] <Firemouth> k
[18:50] <Firemouth> installing...
[18:50] <Firemouth> or so i thought, doing an update
[18:51] <Firemouth> thats better
[18:51] <alkisg> (the installation there is not permanent, it's the exported disk which is like a tmpfs )
[18:52] <Firemouth> or not
[18:52] <Firemouth> ah
[18:52] <Firemouth> ok well its not able to get it
[18:52] <Firemouth> :-/
[18:52] <Firemouth> it can pign google
[18:52] <Firemouth> so dns / routing / internet access is good
[18:53] <Firemouth> went in just fine on the server
[18:53] <alkisg> apt-get update && apt-get install ethtool, can't get ethtool?
[18:53] <Firemouth> trying
[18:53] <Firemouth> i ran those two separately already thought
[18:53] <Firemouth> update then install
[18:53] <alkisg> OK
[18:54] <alkisg> If your server has the same arch, try scp user@server:/usr/sbin/ethtool /tmp/
[18:54] <Firemouth> Failed to fetch http://ftpmaster.internal/ubuntu/pool/main/e/ethtool/ethtool_2.6.34-2_i386.deb Size mismatch
[18:54] <Firemouth> that domain name looks wrong eh
[18:55] <alkisg> Ah it's your sources.list
[18:55] <alkisg> You can scp it from the server if you want
[18:55] <Firemouth> k trying that
[18:55] <alkisg> /etc/apt/sources.list
[18:56] <Firemouth> hm
[18:56] <Firemouth> no such file or directory
[18:56] <Firemouth> (on the ethtool)
[18:57] <alkisg> Try `ls /usr/sbin/ethtool` on the server
[18:57] <Firemouth> no such file or dir
[18:57] <alkisg> Didn't you say you installed it?
[18:58] <alkisg> sudo apt-get install ethtool
[18:58] <Firemouth> got the sources
[18:58] <Firemouth> sure did
[18:58] <Firemouth> yeah i used it to cehck the link speed on the server
[18:58] <alkisg> which ethtool
[18:59] <alkisg> That tells you where it's installed
[18:59] <alkisg> It should be in /usr/sbin/ethtool
[18:59] <Firemouth> /sbin/ethtool
[18:59] <Firemouth> im trying to do the update / install again
[18:59] <alkisg> Is that edubuntu? Which version?
[18:59] <alkisg> In my Lucid, it's in /usr/sbin/ethtool
[18:59] <Firemouth> yup, edubuntu
[19:00] <Firemouth> 10.10
[19:00] <Firemouth> but
[19:00] <Firemouth> i got the ethtool installed on the client by copying the source file
[19:00] <Firemouth> showing 100mbits
[19:00] <Firemouth> so thats not it
[19:00] <alkisg> Right. So you're as good as it gets
[19:00] <alkisg> E.g. if you try to play a divx video on the client, you should be able to watch it full screen with no dropped frames
[19:01] <Firemouth> interesting
[19:01] <Firemouth> tux typing doestn want to seem to do it
[19:01] <Firemouth> i'd like to try testing something like you're saying, any suggestions how to easily test the video liek you're saying?
[19:01] <Firemouth> try youtube or something?
[19:01] <alkisg> Btw seems that ethtool got moved from lucid to maverick: http://packages.ubuntu.com/lucid/i386/ethtool/filelist vs http://packages.ubuntu.com/maverick/i386/ethtool/filelist
[19:02] <alkisg> So that's why you couldn't find it in /usr/sbin/ethtool
[19:02] <Firemouth> ahhh
[19:02] <alkisg> Not flash
[19:02] <alkisg> Open something in totem
[19:02] <Firemouth> k, gotta erboot the client, i removed taht shell line
[19:03] <alkisg> No need keep it till you get it right
[19:03] <alkisg> You can return to your GUI with alt+ctrl+f7
[19:03] <Firemouth> oh
[19:04] <Firemouth> hm there arent any sample videos on here are there?
[19:04] <Firemouth> (this is basically a fresh install)
[19:06] <alkisg> No idea, just get one from the net, e.g. http://www.greektube.org/download.php?vid=89683
[19:07] <Firemouth> k downloading
[19:11] <Firemouth> hm
[19:11] <Firemouth> needs some codecs
[19:12] <Firemouth> tries to install them but fails
[19:12] <Firemouth> untrusted packages
[19:12] <Firemouth> and just fails lol
[19:12] <Firemouth> lemme try something else
[19:13] <Firemouth> and im drawing a total blank lol
[19:16] <Firemouth> k i think i got soemthign to test
[19:16] <Firemouth> gimmie just a few min
[19:17] <Firemouth> i have an avi and wmv
[19:21] <Firemouth> good grief
[19:21] <Firemouth> i cant install these plugins
[19:21] <Firemouth> gstreamer0.10-plugins-ugly
[19:21] <Firemouth> gstreamer0.10-ffmpeg
[19:22] <Firemouth> gstreamer0.10-fluendo-mp3
[19:25] <Firemouth> ok, gpupdate looks like it fixed taht problem
[19:27] <Firemouth> wow
[19:27] <Firemouth> there it goes
[19:27] <Firemouth> watching clerks no problem
[19:28] <Firemouth> thats amazing
[19:28] <alkisg> Right. So your setup is fine.
[19:28] <alkisg> Anything else is app specific
[19:28] <Firemouth> well that just sucks then, lol
[19:28] <alkisg> E.g. full screen flash sucks because it doesn't use XV
[19:28] <Firemouth> gotcha
[19:28] <alkisg> SDL also sucks sometimes (tux* uses SDL afaik)
[19:29] <Firemouth> i guess i dont get it then, rhetorical question.... why would they package edubuntu with tux typing if it cant be used via thin client...
[19:29] <Firemouth> unless it just wasnt meant to be used that way?
[19:30] <Firemouth> i'm new to this virtual desktop stuff so i'm not well versed on the limitations
[19:30] <Firemouth> this is just amazing to me though
[19:30] <Firemouth> streaming a movie
[19:30] <Firemouth> (i'm easily amazed at times)
[19:31] <alkisg> That's not streaming in the usual sense
[19:31] <alkisg> It's just remote X
[19:31] <Firemouth> ah
[19:32] <Firemouth> however it's doing it, its doing it ;)
[19:32] <alkisg> So while the movie is encoded at e.g. 1 mbps, you're using 50 mbps
[19:32] <alkisg> Because the movie travels unencoded, uncompressed
[19:32] <Firemouth> interesting
[19:32] <Firemouth> server is holding steady @ 10.9mbits
[19:32] <alkisg> So all the decoding happens on the server, so your client could be e.g. just 300 mhz
[19:33] <alkisg> Then it's a small movie. You can use any movie up to 95 mbps with your current network
[19:34] <Firemouth> yeah its a 600mbish file
[19:34] <Firemouth> not the best copy, hehe
[19:36] <Firemouth> sweet
[19:36] <Firemouth> well thank you for all your help
[19:36] <alkisg> np
