<ltspuser_78>
Hello
10:57
<gvy>
hi
10:58
<ltspuser_78>
can anybody help me with a rather peculiar problem regarding LTSP and sound on Thin clients?
11:00
<gvy>
well I'm not using ubuntu/debian variants but there might be generic troubles...
11:04
<ltspuser_78>
I'm running LTSP with Edubuntu 12.04 on a VM (Esxi) and have a mix of hp t5720 and t5520 thin clients connected. They all work fine with one exception
11:05
the sound only works on the t5720's and NOT on the t5520's
11:05
they both have the same audio cards (AC97)
11:05
<gvy>
ac97 is a name of a standard IIRC, the chips might be vastly different
11:06
look up how to log in locally at the clients (requires root password set in whatever remote root filesystem the clients do get)
11:06
then get a console login there (ctrl-alt-f1 or f2, root, password)
11:07
then run "lsmod | grep snd" to get the list of ALSA drivers loaded and compare these
11:07
if alsa-utils package is installed (should be) then alsamixer should present a text UI where the main interest is Master and PCM ("m" mutes/unmutes, arrow keys change, esc exits)
11:08
might be just zero level on some of these two channels
11:08
<ltspuser_78>
ah right, lemme try this straight away
11:09
<gvy>
or the other way around, try booting the clients off a usbflash with a "live" version of a distro to verify that the drivers get loaded and there's no "simpler" problem of no hardware support
11:09
albeit that would be quite unexpected for these imho

!localxterm
12:55
<ltsp>
localxterm: Any applications that you launch on a thin client actually runs on the server, not on the client itself. If you want to open a program on the client locally, you can type 'ltsp-localapps <program>' in a run dialog or in a terminal. For example, 'ltsp-localapps xterm' to open a terminal running on the client.

<wicksey>
We use virtualbox booting via pxe to connect MacBooks to our LTSP server. Is there a 'lighter' way, just using X remotely to connect to ldm? FreeNX? Just X through ssh to the ldm login screen?
