| |
| 01:26 | I;m doing auto logon, and it's working. But when I create a user, the home folder is not being created, yet I can see it on the LTSP-booted XFCE desktop.

| 17:23 | <Ark74> hi!
| |
| 17:24 | i found that i had a non-xvideo compatible client
| |
| 17:25 | the video i streamed to it was with no color, just like gray shadows moving on the screen
| |
| 17:25 | *had no color
| |
| 17:25 | but since i used, http stream, i used firefox to watch the video
| |
| 17:26 | (stream)
| |
| 17:26 | and it showed correctly.
| |
| 17:26 | *displayed

| 18:50 | <||cw> Ark74: yes, video streaming is something that s difficult for thin clients. localapps is best.
| |
| 18:53 | <Ark74> ||cw, somethin like having the video file on each station and play it from it with a localapp?
| |
| 18:53 | <||cw> Ark74: no, running firefox, or another video player, local
| |
| 18:54 | <Ark74> ohh, yeah
| |
| 18:55 | ||cw, i had that issue because of the lack of xvideo support on the client
| |
| 19:22 | <alkisg> Ark74: you can check for xv support by running xvinfo
| |
| 19:23 | <Ark74> alkisg, i did, that was the only one with no support, thanks for the tip
| |
| 19:25 | <alkisg> Which card is that? I thought most of them had xv support nowadays... maybe you're using some incompatible xorg version for that card.
| |
| 19:27 | E.g. unfortunately xorg after 1.13 dropped support for all cards that used XAA :-/
| |
| 19:28 | <Ark74> i have no access right now, but i think it was a VIA
| |
| 19:29 | or maybe SiS...no it was a VIA card
| |
| 19:29 | <alkisg> What ubuntu version? 12.04.howmuch?
| |
| 19:29 | <Ark74> yep, 12.04
| |
| 19:29 | <alkisg> how much?
| |
| 19:29 | 12.04.1? .2? etc
| |
| 19:29 | 12.04.2+ dropped support for sis cards, they segfault now
| |
| 19:30 | They only work with the xorg of 12.04.1
| |
| 19:30 | OK anyways, you can't check now...
| |
| 19:31 | <Ark74> yeah, i'm using xserver-xorg 1:7.6+12ubuntu2
| |
| 19:32 | that i can tell
| |
| 19:32 | <alkisg> dpkg -l xserver-xorg-core
| |
| 19:33 | <Ark74> | |
| 19:33 | +++-==========================================-==========================================-====================================================================================================
| |
| 19:33 | ii xserver-xorg-core 2:1.11.4-0ubuntu10.14 Xorg X server - core server
| |
| 19:33 | 1.11
| |
| 19:33 | <alkisg> Yup, you have the original xorg stack, which supports cards with XAA
| |
| 19:33 | So it's OK for SiS etc
| |
| 19:34 | (the chroot is what matters, of course, not the server)
| |
| 19:34 | <Ark74> so i should set something on lts.conf to correct that?
| |
| 19:34 | yeah, sure
| |
| 19:35 | <alkisg> No it's fine, you only need to check that one client, see what card it has, search for workarounds etc
| |
| 19:35 | <Ark74> how good /terrible idea is to use XSERVER=vesa as default on lts.conf?
| |
| 19:36 | <alkisg> Terrible
| |
| 19:37 | Only set that for bad clients. Or, from a script, for all clients from some known bad chipset.
| |
| 19:38 | <Ark74> ok, got it
| |
| 19:40 | alkisg, sorry to ask this again, but why the behaivor was different on firefox and vlc, i mean you already said it was 'cause the xv support
| |
| 19:40 | <alkisg> E.g. vlc would default to xvideo and firefox to x11 rendering
| |
| 19:40 | If you tell vlc to use x11 rendering, it will work too
| |
| 19:41 | <Ark74> x11 rendering will consume more bandwith? or cpu?
| |
| 19:41 | or any?
| |
| 19:41 | <alkisg> Both
| |
| 19:42 | E.g. 640x480 video played back at 1024x768 screen: xvideo bandwidth = 640*480*12bpp
| |
| 19:42 | x11 = 1024*768*32 bpp
| |
| 19:42 | <Ark74> oh, like you wrote here: https://www.mail-archive.com/ltsp-discuss@lists.sourceforge.net/msg41360.html
| |
| 19:42 | <alkisg> And xvideo has hardware acceleration, so it doesn't use much cpu
| |
| 19:43 | <Ark74> so it has really good advantages xv support
| |
| 19:43 | nice
| |
| 19:44 | thanks now i'm aware of xvideo and x11 rendering
| |
| 19:50 | BTW, i started to fill a Flow Control section on the ethernet cards description on h-node.org
| |
| 19:51 | <alkisg> Link?
| |
| 19:51 | <Ark74> stating if they support or not, flow control
| |
| 19:51 | http://ur1.ca/gythg (the real url is huge)
| |
| 19:52 | i'll keep filling this description on the other cards i have
| |
| 19:53 | chances are that i find one that supports disabling flow control
| |
| 19:54 | <alkisg> I have marked a few of them if you want them...
| |
| 19:54 | <Ark74> sure
| |
| 19:55 | <alkisg> Google-translate this one: http://alkisg.mysch.gr/steki/index.php?topic=3533.0
| |
| 19:55 | There's a section for "good network cards" and another one for bad ones
| |
| 19:56 | <Ark74> alright, i'll check it out
