<jimjimovich>
anyone know how to disable the system error "beep" on ubuntu ltsp? it's about 100 times louder than any other sound and scares people because it's so loud.

<muppis>
jimjimovich, do you mean tha one what comes out from pc-speaker, not from soundcard?
00:42
<jimjimovich>
muppis: it comes out of the sound card
00:43
<muppis>
jimjimovich, have look from soundsettings?
00:43
<jimjimovich>
yeah, i have all system sounds turned off
00:46
<muppis>
Using some branded HW, like HP, Dell... ?
00:47
<jimjimovich>
muppis: no, it's on all the terminals, and they're all random generic PC parts
00:47
it makes the error noise, for example, when there is an error in the terminal (like if you're backspacing too far, etc)
00:48
or if you hit "tab" to complete something and there's an error
00:50
<alkisg>
jimjimovich: in gnome-volume-control there's an option to mute alerts

<BenG>
I got my vserver based install of LTSP-5 almost completely working
00:54
one remaining issue is USB keys
00:54
I've seen there is some trouble with local devices in Squeeze
00:54
did anyone find the problem?
00:55
ltspfsmounter script looks sensible, but haven't a clue if it's working as meant to
00:56
I get a mount remote fs in /tmp/.<user>-ltspfs/usbdisksda1, but nothing in /media/
00:56
also the clean up doesn't work
00:57
<muppis>
BenG, there can be missing something. Take a look Ubuntu's script, as it works.
00:58
<BenG>
Debian packages are based on Ubuntu though
00:58
but yes, a good starting point would be to look at the differences
01:05
<muppis>
jimjimovich, did you get it disabled?
01:07
<jimjimovich>
muppis: got called away to another issue, will try now
01:08
<alkisg>
jimjimovich: there's no need to mute it, you can just lower its volume if you want from the slider there.
01:08
<BenG>
muppis, packages look identical, save for one file, which is purely documentation
01:09
<muppis>
BenG, bummer. Any mark of failing in logs?
01:09
<BenG>
no
01:09
also I don't have the system to hand, so it's very limited what I can now
01:10
I'm researching possibilities
01:10
do people has this working on both maverick and natty?
01:10
perhaps I'm missing a log file
01:11
I have syslog remotely logging on the server from each client, and I've looked at /var/log/ldm.log on the clients
01:11
<muppis>
Got Maverick installed at home, but my thins mb failed so I can't test right now.
01:11
<BenG>
anywhere else I should look?
01:11
<jimjimovich>
alkisg: you talking about the "Alert volume" slider?
01:11
<alkisg>
Yes
01:11
<jimjimovich>
for some reason, I can't even replicate the problem now
01:12
<alkisg>
cat sldkfjlskjd<tab><tab>
01:12
<muppis>
BenG, how about serverside logs?
01:12
<BenG>
what would log ltspfs though?
01:12
I'd love to see a direct output of ltspfsmounter as it ran
01:13
<jimjimovich>
alkisg: yeah, that's what I did before and it would beep, now it doesn't beep for me at all. Thanks for the info though, now I'll know where to start next time it pops up.
01:13
<muppis>
If there permission issue on server, then it logged on server. I think.
01:14
<alkisg>
jimjimovich: there's a mute button there, if you clicked on it then it's completely disabled
01:14
<BenG>
muppis, I have access to the logs from here
01:14
<jimjimovich>
alkisg: yeah, I see that, muted or not, and changing the volume, no beep. it's strange.
01:15
<muppis>
alkisg, do you know the trick for server without soundcard and Gnome?
01:15
<alkisg>
muppis: what trick?
01:16
<muppis>
alkisg, to mute that annoying beep..
01:16
<alkisg>
muppis: it's a user setting, you can do that from any thin client
01:16
If you want to enforce a gconf default for all users, you can use gconftool-2 --direct etc
01:17
<muppis>
alkisg, I meant at console ofregular server, not just ltsp.
01:17
<jimjimovich>
okay, so i went to another terminal, and there, it beeps through the soundcard no matter if it's muted or not (and the volume control has no effect)
01:17
<alkisg>
muppis: you mean the pc speaker beep? That's a different problem...
01:17
muppis: disconnect the speaker? :D
01:18
<jimjimovich>
the problem is that the beep is incredibly loud, much louder than any other sounds on the speakers
01:18
<muppis>
alkisg, well.. HP service wont be happy then..
01:18
<alkisg>
jimjimovich: what about the *global* volume control? Does it lower that beep's volume?
01:18
<jimjimovich>
tried that too, and it doesn't have any effect
01:18
<alkisg>
muppis: no idea, maybe you can blacklist the pc speaker module
01:19
jimjimovich: then it's the internal speaker in your case too
01:19
It's not the soundcard
01:19
<jimjimovich>
it's the speakers connected to the soundcard
01:19
<alkisg>
jimjimovich: it's possible that the pc speaker gets directed through the soundcard
01:19
<jimjimovich>
hmmm
01:19
<alkisg>
If the master volume has no effect in it, then that's what's probably happening
01:19
<muppis>
jimjimovich, onboard soundcard?
01:19
<alkisg>
Try removing the pc speaker module
01:19
<jimjimovich>
yes, onboard
01:20
i wonder if the bios has a way to turn it off. they are intel boards with atom processors
01:20
<muppis>
Propably not.
01:20
<jimjimovich>
how would you remove the pc speaker module?
01:20
<alkisg>
modprobe -r
01:21
(locally on the client, not on the server)
01:21
<jimjimovich>
in the chroot then?
01:21
<alkisg>
(i.e. you'd blacklist it on the chroot if that works)
01:21
!SCREEN_02
01:21
<ltspbot`>
alkisg: "SCREEN_02" :: to get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using%20a%20shell%20SCREEN
01:21
<jimjimovich>
ah, got ya
01:21
<alkisg>
That's how to test if it works ^^
01:21
Then if you make it work from the command line, you blacklist it in the chroot
01:22
blacklist pcspkr or something like that
01:23

01:26mistik1 has quit IRC
01:36
<jimjimovich>
alkisg: yeah, it doesn't work to remove that mod. according to the bug you posted, that's what other people experienced too. it only silences the actual internal speaker (of which there is none, in my case)
01:36
<alkisg>
Strange, I'd expect that it doesn't allow port 0x61 output after that
01:37
(that's where the speaker sound is controlled from)
01:37
<jimjimovich>
in the bug, people are saying that the beep still comes through speakers and headphones
01:37
<alkisg>
I see. Then maybe some other module is responsible for that.
01:38
Try asking in #ubuntu
01:44
<jimjimovich>
alkisg: yeah, I'll ask over there. it's kinda crazy. pcspkr is actually disabled by default. also it's interesting that in screen 02, the beep is a different sound than in the normal ltsp environment
01:45
<alkisg>
Hmmm then it probably isn't related to your pc speaker
01:46
The local pc speaker beep is the one from screen_02
01:48
<jimjimovich>
the screen_02 beep also comes through the speakers, but sounds more like a pc beep. the one in the full gnome interface is less annoying sounding but extremely loud

okay, question about usb keys, when the icon pops up on the gnome desktop showing you the key, how does it find it?
03:27
how does gnome know about the key?
03:35
<johnny>
because the client connects to the server and hooks up a directory in /media
03:35
and gnome knows about /media
03:46bobby_C has quit IRC
03:48
<BenG>
johnny, it's the "knows about" bit I want to understand
03:48
also wondering why I don't get proper mounts in /media
03:50
<johnny>
that's a gnome question, you'd have to read more about that
03:50
and also read about ltspfs
03:51
and possibly reading the source
03:53
<BenG>
yep, read the ltspfsmounter script this morning
03:53
looks like it should work :)
03:53
reading on the gnome-volume-manager for clues too, but might have the wrong end of the stick
03:54
or indeed completely the wrong stick

04:45shamino has joined #ltsp
04:46
<alkisg>
jimjimovich: well out of curiosity, sure, say it...
04:46
<jimjimovich>
need to add "set bell-style none" to /etc/inputrc in chroot (I did it on the server too)
04:47shamino has quit IRC
04:47
<jimjimovich>
or you can do "set bell-style visible" to get a visible indicator of the error

Isn't that for "readline" only? That won't affect GUI apps...

Hello, folks!
05:11
A friend of mine has problems with HP Compaq D51S as thin clients: the user is spontaneously logged out of the session and returned to login screen. Any similar experiences?
05:14
My friend says that the logout occurs after 1-2 hours of use. All clients of this type behave in the same way. Other TC's work ok.

07:00
I've now got some output for the errors I get
07:00
usb keys mounting on the desktop is the problem
07:00
they aren't finding their way to /media for a start

Hi
07:48
I've got a classroom set of thin clients (old p4's) using localapps for firefox.
07:48
It works great.
07:49
<mgariepy>
morning everyone
07:49
<dgroos>
I have made instructional videos for students to help them learn how to use different tools.
07:49
Howdy mgariepy
07:50
<highvoltage>
morning mgariepy and dgroos
07:51
<dgroos>
Flash and sound work great, the problem is that when a student plugs in a headphone, while sound comes out of the headphone, it *still* comes out of the speaker on the computer! This is distracting!
07:51
Morning highvoltage--kinda early out west there?
07:52
<highvoltage>
dgroos: 8:52
07:52
<mgariepy>
maybe you need to load the soundcard module with some option
07:52
<dgroos>
Hmmm I thought you were in western Canada...
07:52
<highvoltage>
dgroos: nope, east :)
07:53
dgroos: I favourited some instructional videos on youtube just yesterday: http://www.youtube.com/user/edubuntuproject
07:53
they're quite nice, just a pity about the bad sound quality
07:53
<mgariepy>
sometimes the card doesn't detect correctly when the headphone is plugged-in and doesn't mute the other channel.
07:53
<highvoltage>
dgroos: if any of yours are on youtube, let me know and I'll add it too
07:54
<dgroos>
mgariepy--I'll check into sound cards after school, thanks. Interesting that almost all google hits about sound issues seem to be from Hardy or earlier days...
07:55
highvoltage: Unfortunately I can't even check out those videos now as my district blocks youtube :( though can on cell :)
07:56
<highvoltage>
dgroos: heh, ok
07:58
<dgroos>
Here are 3 that I made for today--posted them on a wiki supplied to me by the district... http://wiki.mpls.k12.mn.us/groups/gcos/wiki/42568/FLE4.html They are not exciting but do what I need them to do.
08:01
mgariepy: do you have any favorite pages that explain the process of ltsp-soundcards-localapps-lucid? This one will be helpful, I believe: http://manpages.ubuntu.com/manpages/lucid/man5/lts.conf.5.html
08:07Gadi has joined #ltsp
08:10
<dgroos>
I wonder what percentage of school districts in US and other countries block youtube?
08:11
<highvoltage>
I guess quite a lot, considering just the amount of bandwidth it eats
08:11
<mgariepy>
sorry dgroos i don't have documentation on soundcard i just remember we had a few problem back on interpid or something like that
08:13
<dgroos>
hmmm... I know that there are commands to find out one's soundcard and that I can find docs about finding and installing drivers, I'm just wondering how configure. Maybe I'll be back here after school :)

G'morning all - LTSP on 10.04, dual xeon 3 GHz, RAID1, 8 gb ram. I lost connection to the server doing a dist-upgrade to get the new kernels. I was able to get back in and ssh, but couldn't reconnect to apt-get session (didn't know how). I restarted, and ran dpkg --configure -a to resume.
09:22
It appeared to work, GRUB ncurses screen came up, I installed it on all 3 disks in the RAID, it appeared to successful. On a reboot, I'm stuck at the initramfs. Any ideas? TIA
09:25
<Gadi>
any errors before the initramfs prompt?
09:26
<Mip5>
Yes - one about udev, I think. Can I scroll back on this console screen, or should I reboot and look again (this happened last night)
09:28
<Gadi>
try shift-pageup to scrool
09:28
*scroll
09:29
<Mip5>
shift page up didn't do it, but I just remembered this: ALERT! /dev/disk/by-uuid/3 does not exist. Dropping to a shell.
09:29litlebuda has joined #ltsp
09:30
<Mip5>
That's a search string I put - uuid was long, and contained my unique blkid
09:30
<Gadi>
ah, seems initramfs is looking for a device that does not exist
09:30
and I doubt your uuid is actually 3
09:30
<Mip5>
yeah, sorry.
09:30
<Gadi>
do: ls /dev/disk/by-uuid
09:31
<Mip5>
No such file or directory found
09:31
I tried searching /dev/ for md* or disk* - no luck
09:32
<Gadi>
software RAID or hardware?
09:32
<Mip5>
Software
09:33
<Gadi>
ah
09:33
hmm...
09:34
have you tried loading an older kernel?
09:34
<Mip5>
no - but I don't even get to a grub menu - so I'm not sure how I'd do that.
09:34
<alkisg>
Press left shift while booting
09:35
<Mip5>
alkisg: I assume I'd hit shift after the scsi stuff?
09:35
<highvoltage>
or just keep it in all the way
09:35
<alkisg>
Mip5: when you see the white BIOS letters, press shift and keep it pressed
09:36
<Mip5>
ok - here goes - it takes a while....

09:41
<Gadi>
Mip5: I suggest you boot from a livecd, get the raid array mounted, chroot into it, and do a dist-upgrade
09:42
FYI: "dpkg --configure -a" will fix partially installed packages, but it will not finish a dist-upgrade
09:43
<Mip5>
Rats - I don't have a cd drive on this hardware, and I haven't been able to get it to boot from usb thumb drive. I have access to usb drive though (in another building). Is there no way to chroot into it from here (initramfs)?
09:43
<Gadi>
in the future, run apt-get dist-upgrade again after that
09:43
Mip5: only if you can get the chroot to load the proper drivers and recognize the disk
09:44
but, seeing as that is the problem to begin with....
09:44
:)
09:45
<mgariepy>
Mip5, don't you have an older kernel you can boot on the system ?
09:45
<Mip5>
Ah - okay - thanks. I'll go get the drive, and check in with y'all when I get back. Thanks *so* much for your help.
09:45
mgariepy: I don't know how to get to it. I don't get a grub menu, and holding down shift didn't seem to stall the process - I still got dropped to the initramfs shell (busybox)
09:46
<mgariepy>
ok
09:46
<Mip5>
Back in a bit - thanks again

Gadi: I'm back at the office. Which disk should I have with me when I get back to the server? Initially I used an alternate 10.04
10:05gnunux has quit IRC
10:05
<Gadi>
you can probably use anything. maybe easier for you if it brings up a gnome desktop that automounts the drive
10:05
then, you can just open a terminal window and chroot into it
10:06
<Mip5>
so 10.04 desktop would do the trick
10:06
?
10:06
<Gadi>
I think so - bring both
10:06

Mip5: you can also use network booting if cd / usb won't work
10:12
https://wiki.ubuntu.com/LiveCDNetboot#line-77
10:19
<Kyle__>
alkisg: For the base install? It works, but it is a bit of a pain, and depending on your connection, it can be painfully slow. (I did that before I tried LTSP).
10:20
USB is way way faster

Kyle__: no, for booting a live usb served from a different pc on the local network
10:29
E.g. if you want to install ubuntu on 12 netbooks, you can use that
10:30
Much much faster than usb, even for 1 netbook
10:30
It's so handy I've even scripted it into 1 single command ;)
10:31
*above I meant a live CD, not a live usb

Gadi: my machine is booting the desktop install now, I selected "Try" ubuntu, and am awaiting the desktop
11:17
Gadi: /dev/disk/by-id shows the bare drives in my raid array, and also shows the separate partitions. I don't see /dev/md0, which is my root partition. Not sure what to do next, but I'm thinking I'm going to have get mdadm going
11:19
Question for anyone - does an italicized / grayed out username indicate the user is offline?
11:22
<dberkholz>
in most clients that would indicate away
11:22
<Mip5_>
ok - thanks
11:22
<dberkholz>
the user wouldn't show up in the list if offline
11:22
<Mip5_>
Ah - that makes sense
11:22
<dberkholz>
try right-clicking on a user and see if it will show you an away message
11:27
<Mip5_>
Anyone have an idea of how to mount a software raid array from a live cd?
11:39
<Kyle__>
Mip5_: You need to make sure that the kernel has the software-raid drivers.

Mip5_: Modern kernels autodetect some (most? all?) types of mdadm devices, so if there are no /dev/md devices, you need to modprobe the drivers, or use a different live-cd.
11:41
<Mip5_>
Thanks - what parameters should I use on modprobe?
11:42
<Kyle__>
Mip5_: It's been so long, I can't actually recall. Google for a linux-software-raid howto. Look for the kernel modules.
11:42

ok - thanks

Gadi: firefox crashed on my laptop... I've booted to a live cd. I apt-get installed mdadm, but haven't invoked it - how should I go about mounting my raid disks
12:05
someone suggested modprobe to have my server see the disks - not sure which parameters I should use with that... looking into it....

lunch, huh? maybe that's a good idea.... I've been able to chroot into my old root on the raid, but apt-get dist-upgrade found nothing new to update. Since I'm not even seeing grub when I boot, I think the problem is there. Any ideas of what else to try?

I've chrooted into my /dev/md0, my system root. Anyone know how to verify that GRUB is setup correctly?
13:00
One other thing - when I was running 9.04 on this same box, (using old grub), I had a rootdelay=200 entry there so that the system would wait to see the root filesystem. I haven't had to do that since moving to 10.04, but I don't even know *how* to do that in GRUB2. Ideas?

on a fresh install of 10.10 I get Error: failed to connect to NBD server, even though I can see it is spawning a nbd session on the server

I was able to add a rootdelay=200 to the line in /etc/default/grub, but when I tried to run update-grub, I get the error: cannot find a device for / (is /dev/ mounted?)
13:20
Do I have to specifically mount /dev in this chrooted environment? I guess I'm confused. I thought I was running from the chroot, in which case, /dev (and the things I see there) are already available to the system. Any ideas?
13:39
Gadi - you there? Any chance we can pick this back up?
13:42
<alkisg>
rootdelay=200? Pause for 3 minutes before mounting the root file system?!

See how to mount /dev etc and chroot there

dont use rootdelay

13:43
just use rootwait
13:44
<johnny>
ogra, obsolete rootwait and rename it to rootstandstill
13:46
<Mip5_>
Thanks - so I'd swap out rootdelay=200 for rootsandstill (and not provide any other parameter)?
13:50

alkisg: I've read the wiki and have been successful up until grub-install - I'm not sure how to specify this with my software raid disks. I tried using grub-install /dev/md0, and got the error (Attemping to install GRUB to a partition instead of the MBR. This is a BAD idea.
14:49
alkisg: followed by embedding is not possible , but this is required when the root device is on a RAID array
14:50
alkisg: I was able to execute update-grub after editing the /etc/default/grub file. Maybe that will do the trick anyway....

alkisg: if you're still around, I'm still getting dropped to the shell (initramfs), but at least I'm now seeing GRUB. I guess I'll try to boot the previous kernel .... I'm happy to see GRUB, so this feels like some success (btw - same error as before can't find disk by-uuid - is the last error I see before the shell

Booting to the other options doesn't seem to help. Given that it's saying it can't find disk-by-uuid-xxxx, should I try using the /dev/md0 instead?

No, to press "e" in grub and change the uuid with a device
16:02
In the initramfs prompt, can you see the raid disk?
16:02
<Mip5_>
I can't see /dev/md0, which is the raid disk, from initramfs
16:04
<alkisg>
I've never used a software raid so I can't help you there, but trying to see the disk from the initramfs sounds like the way to go there. Try asking in #ubuntu or in #ubuntu-server.

Hey Gang - just wanted to report on the issues of intramfs shell. I think the issue was that my new kernel didn't completely install, and the initrd file was corrupted. I was able to boot into an older kernel, and from there, reinstall the lastest kernel. That recreated an initrd file that worked, and I was able to boot to it. Thanks for the help. Peace.

<Naruni>
any thoughts as to how well the via m'serv would hold up as a ltsp server? how many clients could a 1.6ghz 64bit cpu serve?
22:52
<johnny>
depends on the clients
22:52
it's really more about ram than anything else
22:53
you want 256 + (192 * clients)
22:54alkisg has joined #ltsp
22:54
<johnny>
of coruse.. that also depends on the workload.. that's a minimum there
22:54mordocai has quit IRC
22:55
<Naruni>
well the thing can support 4gb ram, does a client not use much cpu time?
22:58
i remember reading a page about selecting hardware, but cant find it now
22:59mordocai has joined #ltsp
22:59MorningSon has quit IRC
23:00
<johnny>
Naruni, well, it depends on your client hardware
23:00
and which apps you can and will run locally
23:01
Naruni, i use ltsp, but i had a different constraint
23:02
<Naruni>
i might be setting up a server and clients for a car dealership
23:02
<johnny>
the server machine was also the machine that ran the customer user data
23:02
err
23:02
worker user apps
23:02
firefox, our pos app, sometimes openoffce
23:02
<Naruni>
yeah probably the same stuff, only thing they use different is a win32 application that calculates loan payments and junk
23:03
<johnny>
no.. i mean.. i had to run those apps on teh server
23:03
so i do't really know what it actually looks like to run a normal ltsp setup :)
23:03
<Naruni>
ok so if there are 3 clients all running firefox, the server has to be running firefox 3 times?
23:03
<johnny>
with an unladen server.. no personal experience
23:03
<Naruni>
ah i get it now
23:04
<johnny>
in my case. .it would be 4 firefoxes :)
23:04
it was the main computer at a coffeeshop
23:04
and there wasn't much room for other server hardware to go.. just room for the 3 public internet terminals
23:04
originally they were various donated pcs .. i ran through eight of those as more people kept donating
23:04
i even had a gumdrop imac once
23:05
<Naruni>
what were you using as a server?
23:05
<johnny>
2gb ram (it's now 3gb) .. and some sort of dual core athlon
23:05
x2 maybe?
23:05
i don't really remember
23:06
i never really considered the cpu speed to be the blocker (except in the case of flash.. FLASH IS THE WORST)
23:06
so i started by trying to run firefox and flash locally on the client pcs
23:06
<Naruni>
if you dont mind me asking, did you get paid to set this up? and did you have to ever service call
23:06
<johnny>
since the music on the server would get skipped
23:06
if the people on the terminals were watching youtube or whatever
23:06
<Naruni>
yeah flash sucks
23:07
<johnny>
so.. i had say .. 2 p3s witth 512mb ram and a p4 with 128mb ram :)
23:07
err .. sorry .. 256.. not 128..
23:07
i added 128 more..
23:08
but.. it was still too much load on the server.. so with the tech budget i get, i saved up enough and bought 3 new dual core atom boxes (msi wind) and loaded em up with 2gb ram (it was only $15 more than 1gb)
23:08
and now they run the os completely locally
23:08
the server machine os only exists to serve up the images and save the client machine /home directories
23:08
<Naruni>
yeah thats the kinda setup i want
23:09
<johnny>
we call that fat client
23:09
<Naruni>
those dual core atoms are pretty decent, but how are they running flash (youtube and such)
23:09
<johnny>
you'd want 512mb ram on the clients for that
23:09
ah.. just fine i think
23:09
ram is really the problem..
23:09
cpu speed not so much for that.. since everything atom was already 1ghz..
23:10
and it matters more in ltsp when running things locally, as you don't want to use network swap if you don't have to
23:10
in that case.. the server box can be really minimal
23:13
<Naruni>
running the OS on the client... how does that happen?
23:13
<johnny>
oh.. you asked how much i set it up for.. ah.. it's a business i'm coowner of
23:13
<Naruni>
yeah im trying to get into that business 8)
23:13
<johnny>
well in regular ltsp, you do run an os anyways.. just enough of one to be abl to connect to the server
23:13
<Naruni>
oh nevermind not the coffee business
23:13
<johnny>
coffeeshop?
23:14
<Naruni>
stripclub
23:14
j/k
23:14
<johnny>
no.. i mean i coown the coffeeshop, i'm on the tech committee
23:14
there are quite a few other owners
23:14
i rarely ever get support calls
23:15
<Naruni>
so on a client boot, does it call the DHCP server and get a pxe boot command? or does it boot into a OS stored on the client?
23:15
<johnny>
at least once i switched to the new hardware..
23:15
the first
23:15
in both regular ltsp, and this
23:15
this use the same base layer for what regular ltsp uses, it just adds more packages, and tells it to boot the local install
23:15
instead of trying to connect to the remote server
23:15
but it's still retrieved in the same way
23:23
<Naruni>
interesting
23:23
thank, gnight
