| serenity | hi there | 13:25 |
| serenity | is anyone of you using a whiteboard together with a wiimote? | 13:25 |
| nubae | serenity: funny u should ask that | 14:07 |
| nubae | I am in the process now of setting one up | 14:07 |
| nubae | have the infrared pens here and the wiimote with the software | 14:08 |
| nubae | but its windows :-/ | 14:08 |
| serenity | :) | 14:08 |
| serenity | i have ir pen and wiimote here, but none of my software wants to connect. Moving the mouse works fine | 14:09 |
| Ahmuck_ | nubae: there is linux software out there for the wii whiteboard | 14:41 |
| nubae | Ahmuck yeah I know, its just where I am deploying they use windows, so had to be windows based | 16:18 |
| alpharesearch | Hello | 16:43 |
| alpharesearch | is it possible to start application in full screen in edubuntu? | 16:44 |
| 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 | 16:45 |
| 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 | 16:46 |
| nubae | think we call it lockdown manager now | 16:47 |
| alpharesearch | because he likes toohh, I found the lockdown editor... | 16:48 |
| alkisg1 | There's a guest mode in recent ubuntu versions, that's fine for this thing... | 16:49 |
| 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 | 16:50 |
| alpharesearch | how you turn kiosk mode on? | 16:51 |
| alkisg1 | (the guest mode is 2 clicks away, no need to log off) | 16:51 |
| alpharesearch | the pc is dedicated for the kids anyway, the main account is like a guest account | 16:52 |
| alpharesearch | but if the window closes all the work is lost and the kid could get sad | 16:53 |
| === alkisg1 is now known as alkisg | ||
| 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 | 16:54 |
| alkisg | ...and I don't know if/how it's feasible to direct input only to a specific app. | 16:55 |
| alpharesearch | thanks for the keyboard shortcut solution!!! Linux has all the solution build in, it is just always had to find the stuff ;) | 16:57 |
| alkisg | There's also the possibility to specify that this app always stays on top, that would also help a little bit | 16:58 |
| 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 | 17:00 |
| alkisg | Hm? I didn't get what you said | 17:01 |
| alkisg | I've tried both and work fine for me. | 17:01 |
| alpharesearch | I messed it up, because I also pressed alt+tab and this alt+F11 again and now it locks in full screen??? | 17:03 |
| 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 | 17:04 |
| alpharesearch | OK I got it, I need to click with the mouse on the window once... | 17:05 |
| === nubae1 is now known as Nuba1 | ||
| === Nuba1 is now known as nubae | ||
| alpharesearch | alkisg: how can I get the full screen to work with tux paint... the ALT+F11 is not working? | 17:17 |
| alkisg | I don't have it installed, I don't know, but I think it has a --full-screen command line option or something. | 17:22 |
| alpharesearch | yes, you are right again... there is a --fullscreen command line argument... | 17:26 |
| skipjack | Hello | 18:16 |
| 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? | 18:20 |
| alkisg | " the video beginns to slow down ( thicken ) " ==> you mean the audio? | 18:23 |
| 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 .. | 18:24 |
| alkisg | So that would also be true if the video didn't contain any audio? | 18:25 |
| skipjack | I think the Video is okay when I disabled sound. | 18:27 |
| 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 | 18:28 |
| 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? | 18:29 |
| 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 :) | 18:30 |
| 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 | 18:31 |
| 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, | 18:32 |
| 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... | 18:33 |
| 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 :) | 18:34 |
| skipjack | hehe okay? | 18:35 |
| alkisg | Did you actually install the nvidia drivers on the chroot? | 18:35 |
| skipjack | yes | 18:35 |
| 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 | 18:36 |
| skipjack | hm whou can I do this? because thinclient hast X / connected to server. | 18:37 |
| alkisg | You supposedly have SCREEN_02=shell, | 18:37 |
| 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 | 18:38 |
| 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 | 18:39 |
| 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 | 18:40 |
| skipjack | okay? | 18:41 |
| skipjack | hm but, the Xserver does not start when I don't load nvidia driver | 18:41 |
| alkisg | Ah, skipjack, also try with X_COLOR_DEPTH=16 | 18:53 |
| alkisg | It should need a little less cpu | 18:53 |
| 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) | 18:56 |
| skipjack | okay, the Load "glx" is in my xorg.conf and the module is loaded | 19:01 |
| skipjack | but I will reduce to 16 | 19:01 |
| skipjack | hmm | 20:34 |
| skipjack | is there an good way to test nvidia hardware Acceleration on thinclient? | 20:36 |
| skipjack | alkisg: okay now I have reinstalled nvidia driver and I think there must now Hardware Support on. | 20:49 |
| 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 | 20:50 |
| alkisg | See the "idle" part | 20:51 |
| skipjack | okay | 20:51 |
| alkisg | E.g. "80.8%id" | 20:51 |
| 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 | 20:52 |
| alkisg | Run sudo apt-get install iftop on the server and then sudo iftop | 20:53 |
| alkisg | (while the video plays) | 20:53 |
| 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 | 20:54 |
| 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... | 20:55 |
| 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.. | 20:56 |
| skipjack | hmm wait lets look a while | 20:57 |
| alkisg | What's the video attributes? | 20:57 |
| alkisg | width, height, fps? | 20:57 |
| 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 | 20:58 |
| 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 | 20:59 |
| 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 | 21:00 |
| 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 | 21:01 |
| 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 | 21:02 |
| 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 | 21:03 |
| skipjack | okay | 21:04 |
| skipjack | hmm | 21:04 |
| alkisg | Yeah, it looks like pulse crashed and that was the cause of the disconnection | 21:04 |
| 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 | 21:06 |
| skipjack | okay | 21:07 |
| skipjack | client is restarting | 21:07 |
| skipjack | alkisg: okay client is back | 21:10 |
| skipjack | What can I do for debugin now? | 21:10 |
| 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 | 21:12 |
| skipjack | wait, musst first read where iftop what displayed.. | 21:13 |
| skipjack | hmm | 21:23 |
| skipjack | hard to debug, after few secs. totem stop playing because pulseaudio is crashing? | 21:23 |
| 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 | 21:24 |
| skipjack | okay, but where are the pulseaudio logs? | 21:25 |
| pygi | hi folks :p | 22:35 |
| pygi | the evil highvoltage folks and stgraber and others :p | 22:35 |
| skipjack | is it possible to run skype on ThinClients? .. I think this must run as localapp or? | 23:28 |
