[01:34] Unfinished description at https://blueprints.launchpad.net/ubuntu/+spec/packageselection-edubuntu-n-seed-review [01:38] hmm, indeed, fixed. [01:42] heh === highvolt1ge is now known as highvoltage [04:27] highvoltage: have you had a chance to do anything with debmower? === Nubae is now known as Nubae_away [13:55] 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 :) === Nubae_away is now known as Nubae [17:46] hello [17:46] i'm having some performance problems with client computers using edubuntu [17:47] i have two identical laptops, one is the server and one is booting off the network [17:47] im trying to use Tux Typing [17:47] it works fine on the server laptop [17:47] but its a slide show on the client [17:48] anyone have any suggestions on how to improve the performace on the client laptop? [18:26] maybe a step in the right direction... i verified the server is connected at 100mbits [18:26] is there a way i can check to see what speed the client is connected to the network? [18:27] 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] Firemouth: are you using LTSP? [18:31] yes [18:31] Do you have LDM_DIRECTX=True in lts.conf? [18:31] 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] Sure, do this: [18:32] sudo gedit /var/lib/tftpboot/ltsp/i386/lts.conf [18:32] And put the following into that file, if it's empty: [18:32] [Default] [18:32] LDM_DIRECTX=True [18:32] Then reboot the client, you should see great improvement. [18:32] BUT there's a security cost, so after trying it, go and read the ltsp docs [18:33] its a local lan so security isn't a concern [18:33] k got it in there, rebooting client [18:35] hmm [18:35] not seeing any improvement [18:35] do i need to reboot anything on the server? [18:35] i did a full reboot of the client [18:36] Just the client [18:36] hm [18:36] On the client, open a gnome terminal [18:36] There, run this command: ltsp-localapps xterm [18:36] An xterm will open [18:36] On that xterm, run this command: getltscfg -a [18:36] And paste the contents [18:37] says its not currently installed [18:37] You missed something [18:37] Did an xterm open? [18:37] sorry i must be missing something [18:38] i did Applications -> Accessories -> Terminal [18:38] are you looking for something different? [18:38] oh crap [18:38] i missed a step, sorry [18:38] :) [18:38] ok [18:38] got the xterm jup [18:38] up* [18:39] That's called a "local xterm". Run that `getltscfg -a` command there. [18:39] LDM_DIRECTX="True" [18:39] export LDM_DIRECTX [18:39] OK. Continue with: lspci -nn -k | grep -A 2 VGA [18:41] 01:00.0 VGA compatible controller [0300]: nVidia Corporation G72M [GeForce Go 7400] [10de:01d8] (reva1) [18:41] Subsystem: Sony Corporation Device [104d:81e6] [18:41] Kernel driver in use: nouveau [18:42] OK, I don't see anything bad there [18:42] is there a way to confirm the client is connected @ 100mbits ? [18:42] E.g. you should be able to watch full screen video with no lost frames [18:42] Sure, with the ip command [18:42] Let me find the exact syntax... [18:43] (so that you don't have to install ethtool...) [18:43] oh [18:43] already installed it [18:43] In the chroot? [18:43] not sure, i did sudo apt-get install ethtool on the server [18:43] Then nope :) [18:43] hehe k [18:48] Hmmm more difficult than I thought :D [18:48] OK, try this: [18:48] yeah i was playing with it, not getting anywhere [18:48] Open lts.conf again, and add this at its bottom: [18:48] k [18:48] SCREEN_02=shell [18:48] Reboot the client. [18:48] When it boots, press alt+ctrl+f2 [18:48] There, run: apt-get install ethtool [18:48] And then: ethtool eth0 [18:49] k [18:50] installing... [18:50] or so i thought, doing an update [18:51] thats better [18:51] (the installation there is not permanent, it's the exported disk which is like a tmpfs ) [18:52] or not [18:52] ah [18:52] ok well its not able to get it [18:52] :-/ [18:52] it can pign google [18:52] so dns / routing / internet access is good [18:53] went in just fine on the server [18:53] apt-get update && apt-get install ethtool, can't get ethtool? [18:53] trying [18:53] i ran those two separately already thought [18:53] update then install [18:53] OK [18:54] If your server has the same arch, try scp user@server:/usr/sbin/ethtool /tmp/ [18:54] Failed to fetch http://ftpmaster.internal/ubuntu/pool/main/e/ethtool/ethtool_2.6.34-2_i386.deb Size mismatch [18:54] that domain name looks wrong eh [18:55] Ah it's your sources.list [18:55] You can scp it from the server if you want [18:55] k trying that [18:55] /etc/apt/sources.list [18:56] hm [18:56] no such file or directory [18:56] (on the ethtool) [18:57] Try `ls /usr/sbin/ethtool` on the server [18:57] no such file or dir [18:57] Didn't you say you installed it? [18:58] sudo apt-get install ethtool [18:58] got the sources [18:58] sure did [18:58] yeah i used it to cehck the link speed on the server [18:58] which ethtool [18:59] That tells you where it's installed [18:59] It should be in /usr/sbin/ethtool [18:59] /sbin/ethtool [18:59] im trying to do the update / install again [18:59] Is that edubuntu? Which version? [18:59] In my Lucid, it's in /usr/sbin/ethtool [18:59] yup, edubuntu [19:00] 10.10 [19:00] but [19:00] i got the ethtool installed on the client by copying the source file [19:00] showing 100mbits [19:00] so thats not it [19:00] Right. So you're as good as it gets [19:00] 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] interesting [19:01] tux typing doestn want to seem to do it [19:01] 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] try youtube or something? [19:01] 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] So that's why you couldn't find it in /usr/sbin/ethtool [19:02] ahhh [19:02] Not flash [19:02] Open something in totem [19:02] k, gotta erboot the client, i removed taht shell line [19:03] No need keep it till you get it right [19:03] You can return to your GUI with alt+ctrl+f7 [19:03] oh [19:04] hm there arent any sample videos on here are there? [19:04] (this is basically a fresh install) [19:06] No idea, just get one from the net, e.g. http://www.greektube.org/download.php?vid=89683 [19:07] k downloading [19:11] hm [19:11] needs some codecs [19:12] tries to install them but fails [19:12] untrusted packages [19:12] and just fails lol [19:12] lemme try something else [19:13] and im drawing a total blank lol [19:16] k i think i got soemthign to test [19:16] gimmie just a few min [19:17] i have an avi and wmv [19:21] good grief [19:21] i cant install these plugins [19:21] gstreamer0.10-plugins-ugly [19:21] gstreamer0.10-ffmpeg [19:22] gstreamer0.10-fluendo-mp3 [19:25] ok, gpupdate looks like it fixed taht problem [19:27] wow [19:27] there it goes [19:27] watching clerks no problem [19:28] thats amazing [19:28] Right. So your setup is fine. [19:28] Anything else is app specific [19:28] well that just sucks then, lol [19:28] E.g. full screen flash sucks because it doesn't use XV [19:28] gotcha [19:28] SDL also sucks sometimes (tux* uses SDL afaik) [19:29] 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] unless it just wasnt meant to be used that way? [19:30] i'm new to this virtual desktop stuff so i'm not well versed on the limitations [19:30] this is just amazing to me though [19:30] streaming a movie [19:30] (i'm easily amazed at times) [19:31] That's not streaming in the usual sense [19:31] It's just remote X [19:31] ah [19:32] however it's doing it, its doing it ;) [19:32] So while the movie is encoded at e.g. 1 mbps, you're using 50 mbps [19:32] Because the movie travels unencoded, uncompressed [19:32] interesting [19:32] server is holding steady @ 10.9mbits [19:32] So all the decoding happens on the server, so your client could be e.g. just 300 mhz [19:33] Then it's a small movie. You can use any movie up to 95 mbps with your current network [19:34] yeah its a 600mbish file [19:34] not the best copy, hehe [19:36] sweet [19:36] well thank you for all your help [19:36] np === dgroos_ is now known as dgroos === ogra is now known as Guest96219 === Guest96219 is now known as ogra_
