[12:17] <stan_> hello
[13:25] <serenity> hi there
[13:25] <serenity> is anyone of you using a whiteboard together with a wiimote?
[14:07] <nubae> serenity: funny u should ask that
[14:07] <nubae> I am in the process now of setting one up
[14:08] <nubae> have the infrared pens here and the wiimote with the software
[14:08] <nubae> but its windows :-/
[14:08] <serenity> :)
[14:09] <serenity> i have ir pen and wiimote here, but none of my software wants to connect. Moving the mouse works fine
[14:41] <Ahmuck_> nubae: there is linux software out there for the wii whiteboard
[16:18] <nubae> Ahmuck yeah I know, its just where I am deploying they use windows, so had to be windows based
[16:43] <alpharesearch> Hello
[16:44] <alpharesearch> is it possible to start application in full screen in edubuntu?
[16:45] <alpharesearch> for example if my 2 year old plays potato guy I don't want he to close the window...
[16:45] <alpharesearch> or start other applications
[16:45] <alpharesearch> so it would be good to have him lock down to just one window
[16:46] <alpharesearch> it would also a good feature to have a keyboard lock, so only keys go to the application but not to X system
[16:46] <nubae> alpharesearch: take a look at pessulus to lock down stuff
[16:47] <nubae> think we call it lockdown manager now
[16:48] <alpharesearch> because he likes toohh, I found the lockdown editor...
[16:49] <alkisg1> There's a guest mode in recent ubuntu versions, that's fine for this thing...
[16:50] <alkisg1> I use it when my wife wants to feed my 3 y.o. son while playing on my pc :)
[16:50] <nubae> oh kiosk mode is like that 2 I guess
[16:51] <alpharesearch> how you turn kiosk mode on?
[16:51] <alkisg1> (the guest mode is 2 clicks away, no need to log off)
[16:52] <alpharesearch> the pc is dedicated for the kids anyway, the main account is like a guest account
[16:53] <alpharesearch> but if the window closes all the work is lost and the kid could get sad
[16:54] <alpharesearch> i want to start a application for the kid and lock the pc down, let the kid play and come back later and unlock and may start a different application
[16:54] <alkisg> Ah, ok. Well you can set the key for full-screen in gnome keyboard shortcuts, e.g. I've set it to Alt+F11
[16:55] <alkisg> ...and I don't know if/how it's feasible to direct input only to a specific app.
[16:57] <alpharesearch> thanks for the keyboard shortcut solution!!! Linux has all the solution build in, it is just always had to find the stuff ;)
[16:58] <alkisg> There's also the possibility to specify that this app always stays on top, that would also help a little bit
[17:00] <alpharesearch> I just tried the always on top and with the alt+F11 i was not able to switch back... I had to close the game
[17:01] <alkisg> Hm? I didn't get what you said
[17:01] <alkisg> I've tried both and work fine for me.
[17:03] <alpharesearch> I messed it up, because I also pressed alt+tab and this alt+F11 again and now it locks in full screen???
[17:04] <alkisg> No, just click on it to get the focus on this window again, and with alt+f11 you'll be able to restore it
[17:05] <alpharesearch> OK I got it, I need to click with the mouse on the window once...
[17:17] <alpharesearch> alkisg: how can I get the full screen to work with tux paint... the ALT+F11 is not working?
[17:22] <alkisg> I don't have it installed, I don't know, but I think it has a --full-screen command line option or something.
[17:26] <alpharesearch> yes, you are right again... there is a --fullscreen command line argument...
[18:16] <skipjack> Hello
[18:20] <skipjack> I  think I have some Problems with video/sound on thinclient. If I play a Video file the video and sound, the video beginns to slow down ( thicken ) and if I play only a Audio File all things sounds good
[18:20] <skipjack> any idea?
[18:23] <alkisg> " the video beginns to slow down ( thicken ) " ==> you mean the audio?
[18:24] <skipjack> no the Video of the Video file is not viewable, only some frames
[18:24] <skipjack> It beginns tu interruppt
[18:24] <skipjack> and a momentlong there is no sound / and no Video ..
[18:25] <alkisg> So that would also be true if the video didn't contain any audio?
[18:27] <skipjack> I think the Video is okay when I disabled sound.
[18:28] <skipjack> It could be that I need a faster network?
[18:28] <skipjack> I have here 100mbit
[18:28] <skipjack> and currently only 1 client
[18:28] <alkisg> The video needs much more bandwidth than the audio
[18:29] <skipjack> yes.
[18:29] <skipjack> I think I need 1Gbit
[18:29] <alkisg> Sometimes pulseaudio needs a lot of cpu on the client, though, (there's a bug in launchpad for this), maybe that's your trouble
[18:29] <skipjack> oh okay ;)
[18:29] <skipjack> hm
[18:29] <skipjack> I will check
[18:29] <alkisg> Do you have xv enabled?
[18:30] <alkisg> (run xvinfo on a terminal on the client)
[18:30] <pygi> highvoltage: poke
[18:30] <pygi> ogra_: just saw you in the lobby ... I think :)
[18:31] <skipjack> When I play a Video, it takes a long time to close a window. Could be network traffic or some missmatch config?=
[18:31] <alkisg> That's CPU, usually
[18:31] <alkisg> Do you have LDM_DIRECTX=true or false?
[18:31] <skipjack> true
[18:31] <alkisg> ...and how old is this client?
[18:31] <alkisg> (cpu specs?)
[18:31] <skipjack> Intel Celeron 1200Mhz
[18:32] <alkisg> How do you play the video? In which program?
[18:32] <skipjack> xvinfo (running in an Xterm on thinclient: gives me much output )
[18:32] <skipjack> video Lan
[18:32] <alkisg> So all look fine...
[18:32] <skipjack> hm okay,
[18:33] <alkisg> Are you _sure_ that LDM_DIRECTX=true?
[18:33] <skipjack> Should I install videolan ( vlc) as localap?
[18:33] <alkisg> E.g. you may have forgotten the [default] section on top...
[18:34] <alkisg> ...or maybe you put lts.conf in the wrong path...
[18:34] <skipjack> http://rafb.net/p/cRvSgM43.html
[18:34] <skipjack> my lts.conf
[18:34] <alkisg> Ah, nvidia :)
[18:35] <skipjack> hehe okay?
[18:35] <alkisg> Did you actually install the nvidia drivers on the chroot?
[18:35] <skipjack> yes
[18:36] <skipjack> I think the installation is correct. I add to rc.local @ thinclient the insmod command for nvidia.ko
[18:36] <skipjack> and add rc2.d S17rc.local
[18:36] <alkisg> Hmmm you have a local xterm handy, to try: getltscfg -a
[18:36] <alkisg> ?
[18:36] <alkisg> ...but it should be local, not running on the server...
[18:36] <skipjack> okay
[18:37] <skipjack> hm whou can I do this? because thinclient hast X / connected to server.
[18:37] <alkisg> You supposedly have SCREEN_02=shell,
[18:38] <skipjack> ltsp-localapps xterm
[18:38] <alkisg> so you should be able to switch to it with ctrl+alt+F2
[18:38] <alkisg> ltsp-localapps xterm is also good if you run >=8.10
[18:38] <skipjack> oh okay, so I don't need an local X
[18:38] <skipjack> okay
[18:38] <skipjack> I see the output
[18:39] <alkisg> OK then. Try to run "top" in local xterm while playing the video, to see the cpu usage
[18:39] <pygi> highvoltage: please call/sms me/whatever when you get this, cause my sms is not reaching you :p
[18:40] <skipjack> okay
[18:40] <skipjack> Xorg has 98.8% CPU use
[18:40] <alkisg> So no hw acceleration...
[18:40] <skipjack> I play currently the Video without sound..
[18:40] <alkisg> ...so probably no nvidia drivers
[18:41] <skipjack> okay?
[18:41] <skipjack> hm but, the Xserver does not start when I don't load nvidia driver
[18:53] <alkisg> Ah, skipjack, also try with X_COLOR_DEPTH=16
[18:53] <alkisg> It should need a little less cpu
[18:56] <alkisg> skipjack: when I tried with nvidia drivers in the chroot, I also needed MODULE_01=nvidia and  X4_MODULE_01=glx
[18:56] <alkisg> (in lts.conf)
[19:01] <skipjack> okay, the Load "glx" is in my xorg.conf and the module is loaded
[19:01] <skipjack> but I will reduce to 16
[20:34] <skipjack> hmm
[20:36] <skipjack> is there an good way to test nvidia hardware Acceleration on thinclient?
[20:49] <skipjack> alkisg: okay now I have reinstalled nvidia driver and I think there must now Hardware Support on.
[20:50] <alkisg> skipjack: ok, see the cpu usage, it should be really low for playing xv video
[20:50] <skipjack> the CPU hast 48% when I watching an Movie ( without Sound output )
[20:50] <alkisg> Erm, ok, so the other 50% is idle?
[20:50] <skipjack> top shows me 50% for Xorg
[20:51] <alkisg> See the "idle" part
[20:51] <skipjack> okay
[20:51] <alkisg> E.g. "80.8%id"
[20:52] <skipjack> 41,7%id
[20:52] <skipjack> .. and so on
[20:52] <alkisg> OK, should be more than enough for audio
[20:52] <alkisg> So, if you turn on audio, you still get lag on the video?
[20:52] <skipjack> hm okay, it could be also an misstake of Hardware Acceleration, because I have reduce to 16bit
[20:52] <skipjack> hm I have also lag on video
[20:52] <alkisg> Now see the bandwidth
[20:53] <alkisg> Run sudo apt-get install iftop on the server and then sudo iftop
[20:53] <alkisg> (while the video plays)
[20:54] <skipjack> okay
[20:54] <alkisg> If you have hw acceleration (xv playback), then the bandwidth is WIDTHxHEIGHTxFRAMES_PER_SECONDx12
[20:54] <alkisg> because usually the xv mode selected only uses 12 bits per pixel
[20:55] <alkisg> ...and that's independent of the window size, it only depends on the original video size.
[20:55] <skipjack> hmm okay, em xv module, so vlc should use xv ?
[20:55] <alkisg> Yes. You may try with totem if in doubt...
[20:56] <alkisg> If xv isn't used, then 100mbit is too little for video playback
[20:56] <skipjack> okay
[20:56] <skipjack> ;)
[20:56] <skipjack> hehe t
[20:56] <skipjack> totem played iot better
[20:56] <skipjack> but not perfect..
[20:57] <skipjack> hmm wait lets look a while
[20:57] <alkisg> What's the video attributes?
[20:57] <alkisg> width, height, fps?
[20:58] <skipjack> RIFF (little-endian) data, AVI, 640 x 352, 25.00 fps, video: XviD, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)
[20:58] <alkisg> For xv in vlc: Tools > Preferences > Video > Output : XVideo extension video output
[20:59] <skipjack> of Video File, and the Screen Resolution: 1920x1200
[20:59] <skipjack> okay this is what I have seleced for an test.
[20:59] <alkisg> That's 68Mbps, it should be playing perfectly
[20:59] <skipjack> but then vlc crashed with (wait I generate the message)
[20:59] <skipjack> okay, it was playing good / thing we can call it perfect
[21:00] <alkisg> Ah, and a few more for the audio
[21:00] <alkisg> Still should play ok
[21:00] <skipjack> but now it's stopped playing withe message "Connection Lost"
[21:00] <alkisg> That's not good :)
[21:00] <alkisg> That's with totem or vlc?
[21:00] <skipjack> that was totem
[21:01] <skipjack> I think there is an trouble with pulse audi
[21:01] <skipjack> because after this disconnect message, pulseaudio is crahsed
[21:01] <skipjack> I have now no sound on ThinClient
[21:01] <alkisg> What ubuntu version is that?
[21:01] <skipjack> but the Video is played perfect
[21:02] <skipjack> 9.04
[21:02] <alkisg> There was a bug fix about oss and /dev/snd, I don't know if it has anything to do with what you're experiencing. The fix is in stgraber's repository
[21:03] <alkisg> ...and that's about as far as I can help, I'm not experienced enough to debug pulseaudio problems :)
[21:03] <alkisg> If it persists, try in #ltsp
[21:03] <skipjack> http://nopaste.php-q.net/244066
[21:04] <skipjack> okay
[21:04] <skipjack> hmm
[21:04] <alkisg> Yeah, it looks like pulse crashed and that was the cause of the disconnection
[21:06] <alkisg> Ah, skipjack, you may also want to reboot the client, play the video and check the CPU usage again
[21:06] <alkisg> Because there's also a bug where pulseaudio needs *a lot* of cpu, if it affects you then you should use a different resampling method
[21:07] <skipjack> okay
[21:07] <skipjack> client is restarting
[21:10] <skipjack> alkisg: okay client is back
[21:10] <skipjack> What can I do for debugin now?
[21:12] <alkisg> skipjack: run `top` locally on the client (localapps xterm) and play again the video, and see the idle cpu
[21:12] <alkisg> also, run iftop on the server to monitor the bandwidth
[21:12] <alkisg> (that shouldn't be a problem though)
[21:12] <skipjack> okay
[21:13] <skipjack> wait, musst first read where iftop what displayed..
[21:23] <skipjack> hmm
[21:23] <skipjack> hard to debug, after few secs. totem stop playing because pulseaudio is crashing?
[21:24] <skipjack> cpu idle is in this time: 58%
[21:24] <skipjack> 58%id
[21:24] <alkisg> ok, go to #ltsp, maybe someone will guide you on how to interpret the pulseaudio logs
[21:25] <skipjack> okay, but where are the pulseaudio logs?
[22:35] <pygi> hi folks :p
[22:35] <pygi> the evil highvoltage folks and stgraber and others :p
[23:28] <skipjack> is it possible to run skype on ThinClients? .. I think this must run as localapp or?
