<zdgffdgz>
hello , Note that things like sound and local device support are auto-enabled if the
03:30
corresponding packages are installed, there is no need to manually set these
03:30
options anymore.
03:31
I have no sound on the client. running ltsp 5.
03:31
What are the corresponding packages?
03:33
5.2.4-2 debian squeeze
03:43
<sbalneav>
Could be that the thin client's not detecting the sound card.
03:43
<zdgffdgz>
thin client plays on the server
03:44
beep on client also plays on server
03:47
I also have a problem with a local USB device on the client. How do I mount such device?
03:49
<sbalneav>
We'll need some more information.
03:49
1) What desktop are you using?
03:49
2) How did you build the chroot
03:50
3) What kind of thin client is it?
03:52
<zdgffdgz>
1] fluxbox 2] ltsp-build-client --arch i386 3] hp thin client
03:55
<sbalneav>
Ok, well, that explains it.
03:56
<zdgffdgz>
?
03:56
<sbalneav>
fluxbox doesn't do sound forwarding, and doesn't pop up icons on the desktop like gnome, kde, etc.
03:56
<zdgffdgz>
understood
03:57
No way with fluxbox, as I like fluxbox?
03:58
How about mounting an USB device on the client?
03:58
<sbalneav>
should be mounting. Check in /media
03:59
<zdgffdgz>
nothing in media
04:00
it's vfat
04:01
<sbalneav>
Something's broken then. I used to have a whole page up on the wiki showing how to debug, but it's gone now. Not sure.
04:02
My advice would be to run the gnome2 desktop, see if it mounts with that. If it does, then it's fluxbox related, if not, then there's a deeper problem.
04:03
<zdgffdgz>
I"ll give kde a try, tomorrow, thank!

04:34
<zdgffdgz>
So I installed kde, I did not like what I saw, and removed it again. Back to fluxbox
04:46
<sbalneav>
Did you test if the usb sticks and sound worked?
04:46
<zdgffdgz>
No I did not check, I hate kde
04:48
I couldn't find my favorite xterm, no sound player
04:48
kde's menu is a disaster, like M$
04:49
<sbalneav>
I didn't ask you to install it to see if you liked kde, I asked you to do so to determine whether the problem was related to fluxbox, or another problem.
04:50
Well, anyway, heading to bed.
04:50
<zdgffdgz>
I will try it another time, perhaps tomorrow.

<zdgffdgz>
hello vagrantc, do you know if fluxbox supports local sound and storage(USB)?
05:00
<vagrantc>
zdgffdgz: ltspfs is essentially desktop-independent ... but some desktops make it more obvious with icons on the desktop.
05:01
zdgffdgz: but as long as you're looking in /media/USERNAME/DEVICE you should be able to access your files no matter what desktop you're running.
05:02
zdgffdgz: similar for sound- you may need to configure alsa to redirect to pulse if running on the LTSP client
05:05
<zdgffdgz>
There is no /media/USERNAME on the thin client
05:05
<vagrantc>
are there devices plugged in?
05:06
<zdgffdgz>
yes, also local disc is not there
05:06
<vagrantc>
local disk will not be there unless you explicitly allow local disks
05:06
<zdgffdgz>
in lts.conf?
05:07
<vagrantc>
zdgffdgz: so what sort of devices do you have plugged in?
05:08
<zdgffdgz>
in my /opt/ltsp/i386/etc/lts.conf I have [default] LTSP_CONFIG=True SOUND=True LOCALDEV=True
05:09
USB 64Gb usb-stick
05:09
<vagrantc>
in general USB sticks should show up ... but some prove to be fussy.
05:10
<zdgffdgz>
I tried another one 2 Gb, nodifference
05:11
<vagrantc>
is the user in the fuse group?
05:11
groups | grep fuse
05:12
<zdgffdgz>
no
05:13
<vagrantc>
they need to be in the fuse group... ltspfs is a fuse-based filesystem.
05:14
Enslaver: is your mail from March 1st generally enough to try ltsp on centos?
05:27
<zdgffdgz>
usermod -g fuse USERNAME doesn't change that
05:28
<vagrantc>
zdgffdgz: adduser USERNAME fuse
05:28
that's why i use
05:28
you would also have to logout and log back in again for it to work
05:30
zdgffdgz: are you saying they weren't added to the fuse group, or adding them to the fuse group didn't help?
05:30
or unsure? :)
05:33
<zdgffdgz>
I rebooted the client and now /media/USERNAME shows up
05:33
in it there's a dead link? ?usbdisk-sdc1
05:34
So I made some progress
05:35
<vagrantc>
a link?
05:35
like, a symlink?
05:36
<zdgffdgz>
?usbdisk-sdc1 red colored
05:36
<vagrantc>
zdgffdgz: and the user is now in the fuse group?
05:36
zdgffdgz: ls -l /media/USERNAME
05:37
<zdgffdgz>
d?????? ? ? ? ? ?usbdisk-sdc1
05:38
<vagrantc>
that's a messed up fuse mount... hrm.
05:38
i've seen that before ... rebooting the server cleared it up...
05:39
<zdgffdgz>
OK rebooting the server

05:41
<zdgffdgz>
back up
05:44
media/USERNAME/usbdisk-sdc1 is now an empty directory
05:46
I put in another USB-stick, brings me back to the red colored ?links
05:49
rebooted the client, now it works!!!
05:52
next problem: no sound
05:52
command beep on client beeps on server, system beeps on client
05:53
<vagrantc>
zdgffdgz: this is on debian?
05:54
<zdgffdgz>
yep, squeeze up to date
05:55
<vagrantc>
zdgffdgz: have you followed the instructions in /usr/share/doc/ltsp-server/README*sound ?
05:55
<zdgffdgz>
no

05:56
<alkisg>
Hi vagrantc, hi all
06:11
<vnc786>
question : by default usb is disable or need some parameter in lts.conf ? right now i have nothing in lts.conf but at fat clients are getting usb access
06:12komunista has joined IRC (komunista!~slavko@87.244.209.121)
06:12
<zdgffdgz>
apt-get install libasound2-plugins
06:12
and now the rest ;-)
06:12
<vagrantc>
vnc786: usb storage devices should be supported
06:13
though in theory, fat clients could use more conventional means to get device access.
06:15
vnc786: user needs to be in the fuse group for localdev (ltspfs) to work
06:15
<alkisg>
They do; fat clients don't use ltspfs to access the local devices
06:16
Normal fat client users get access to all external devices without being in the fuse group,
06:16
and sudoers also get access to internal devices like local hard disks
06:17
Access can be customized by policykit, the same as in local installations
06:18
(and we could add lts.conf support for policykit modifications...)

06:28
<vnc786>
LOCALDEV_DENY_USB=True will make not provide access to usb on fat clients ? am i right
06:29
<zdgffdgz>
getting sound on thin client is no easy task
06:29
<vagrantc>
vnc786: like alkisg said, the LOCALDEV support isn't used by fatclients.
06:29
zdgffdgz: depends on the client.
06:30
<vnc786>
vagrantc: i m trying to disable access for fat clients so how do i do..?
06:30
<zdgffdgz>
getting local storage work even needed reboot of server ;-)
06:31
<vagrantc>
vnc786: just like you would for a disked computer
06:31
zdgffdgz: some of those reboots might have been avoidable... but sometimes it's just easiest to reset it.
06:32
vnc786: you could blacklist the usb_storage module ... a bit brute-force ...
06:35
<vnc786>
is there a way using lts.conf file ?
06:37
<vagrantc>
don't know off the top of my head
06:39* vagrantc sleeps
06:40
<vagrantc>
keep the hackfest hacking!
06:40vagrantc has left IRC (vagrantc!~vagrant@freegeek/vagrantc, Quit: leaving)
06:45
<vnc786>
i just put LOCALDEV_DENY_USB=True in lts.conf ..though it will work but no it's not....
06:53
<zdgffdgz>
vnc786 have you got sound on the fat client?
06:58
<vnc786>
zdgffdgz: yes i got sound thru 3.5mm jack headphone
06:59
<zdgffdgz>
I am trying to get sound on my THIN client
06:59
Perhaps you can help me setting it up
07:01
<vnc786>
so u r not getting sound on fatclients or thinclients ?
07:02
<zdgffdgz>
thin
07:03
I've got local storage (USB)
07:03
on the thin client
07:08
<vnc786>
and have u tried using sound parameter in lts.conf ?
07:23
<zdgffdgz>
I have SOUND=True under [default]

vnc786 Is it worthwhile to change from FAT to THIN client? I have 100MHz 2Gb RAM thin client.
07:26
1000MHz ! GHz, sorry
07:28
<warren>
2Gb RAM is 250MB of RAM

<zdgffdgz>
for sound, what has to be installed/changed on the server, and what on the thin client?
08:05
<Hyperbyte>
zdgffdgz, what distro/version?

Hyperbyte, decian squeeze
08:09
5.2.4
08:12
nicest thing to do is have mpd running on the client.
08:23
would be
08:25
<Hyperbyte>
mpd?
08:25
Oh
08:25
I'm not sure why.
08:26
By default, LTSP sends all audio from thin client desktop applications to the client's audio hardware, using pulseaudio
08:26
It should work out of the box, not sure about Debian Squeeze specifically though.
08:29
<zdgffdgz>
mpd can be controlled by any PC, Android device . . .
08:30
LTSP does't work out of the box on debian squeeze
08:32
I had trouble with local access to USB-storage, now solved, Next project: audio. . .

debian squeeze
08:40
<Hyperbyte>
Like I said, LTSP uses pluseaudio.
08:41
It should work.
08:43
<zdgffdgz>
I have pulseaudio on server and client, doesn't work out of the box
08:44
<alkisg>
Is this your first LTSP setup?
08:45
<zdgffdgz>
My first setup was 15 years ago.
08:46
<alkisg>
LTSP didn't exist 15 years ago
08:46
<zdgffdgz>
14
08:47
<alkisg>
OK, anyways, so I assume you're experienced with LTSP... have you ever set up LTSP 5 before?
08:48
<zdgffdgz>
yes, without sound
08:48
<alkisg>
And always in debian squeeze?
08:48
<zdgffdgz>
yes
08:49
<alkisg>
OK. I'd suggest you try another installation with squeeze, backports, and LXDE
08:49
That one should work out of the box
08:49
<zdgffdgz>
14 years ago I even tried susu
08:49
<alkisg>
And then you can compare what runs and whatnot, to troubleshoot your fluxbox one
08:50
<zdgffdgz>
I have backports, fluxbox, is this aproblem?
08:50
<alkisg>
Yes, fluxbox is a problem, the problem being that I haven't heard anyone using it with ltsp
08:50
<zdgffdgz>
OK I'll try LCDE
08:50
<alkisg>
So it's not widely tested, troubleshooted etc
08:51
<zdgffdgz>
lxde being installed
08:51
<alkisg>
With susu you mean suse?

rebooted lxdl
08:56
sound works!!!!!!!!
08:56
But is this possible on fluxbox?
08:58
<alkisg>
It should be, but it's up to you to locate the problems, fix them, and then send patches to ltsp :)
08:58
<zdgffdgz>
hahaha
08:58
<alkisg>
Try also sending mails to the ltsp-discuss ML, maybe someone has used fluxbox and has the solution
08:59
And of course you can file bug reports...

09:00
<alkisg>
Sure
09:00
I'm sure it doesn't work out of the box in 99% of the desktop environments
09:00
As they are hundreds of them
