Nope, since the last time I asked for any assistance in adding
internationalization to ltspfs, no one's come forward with any code or
patches, or any explanation that I can comprehend as to how I might add
it in to ltspfs.

When someone does, I'll be more that happy to do it.  In the meantime,
it's working for me as a North American, so if the international
community wants to use stuff that I wrote, it's up to them to step up to
the plate, and help me to help them. (hint hint).

 Thanks.
 

What about adding utf8 option when creating fstab.

Edit /opt/ltsp/i386/etc/udev/scripts/ltsp-device.sh


It looks like this inside:
...
#
# Create the fstab entry.
#

  MOUNTDIR=/tmp/drives/${MOUNTPOINT}
  mkdir ${MOUNTDIR}
  if [ ${LTSP_DEVTYPE} = cdrom ]; then
echo ${DEVNAME} ${MOUNTDIR} auto ro 0 0  /tmp/fstab.d/${MOUNTPOINT}
echo AddCdromDrive|${MOUNTPOINT}|${DEVNAME}|${DESCRIPTION} \
   /tmp/lbus.fifo
  else
echo ${DEVNAME} ${MOUNTDIR} auto rw,utf8,noatime 0 0 \ #  
utf8 added HERE 
   /tmp/fstab.d/${MOUNTPOINT}
echo AddBlockDevice|${MOUNTPOINT}|${DEVNAME}|0|${SIZE}|${DESCRIPTION} \
   /tmp/lbus.fifo
  fi
...

Works for me.

[Ltsp-discuss] Printing Challenge

2006-11-17 Thread Alexander Hungenberg
Hello list,
I'm new here, so I first want to say hello. But the reason for contacting this 
list is a big challenge with ltsp. I'm a student on a school in Germany and I 
manage the computers with some others...

This summer we decided to bring PC's in each classroom. The perfect solution 
for it: ltsp. Because we bought new PCs for one computer room, we could use 
the 7 years old ones as terminal clients. We only needed to buy a new big 
Server.

Now our problem. The system works very fine, and everything is allright. But 
it would be nice, if we also could print at the terminals. Normally, that's 
no problem. But we want to restrict the access to the printers based on the 
geographical location of the terminal and the printer.

So it would be ideally, if we have a list with the IPs of the terminals and 
then the printers by each IP where you are allowed to print at.

I heard about the possibility to change a cups binary on the server which 
filters the IP of the terminal where the current user works out of the 
DISPLAY variable. With this you could look in the list if it is allowed to 
print on this printer. But I'm not so familiar with CUPS that I know where to 
begin.

Someone on the LinuxWorldExpo in Cologne this week recommended me this list, 
because he knew that here are people, who manage even much bigger terminal 
networks. So I would be grateful if someone can help me with this problem.

Have a nice weekend

Re: [Ltsp-discuss] Printing Challenge

2006-11-17 Thread Joe Auerbach
You know, I never thought about this before, but is it possible to have 
the printer default to the ltsp kernel?

For example, have ten copies of the kernel in 10 directories and each 
directory has a printer defaulted somewhere in it.  Is that possible, or 
is it all dependent on the login?

Another question to ask would be whether there's a printer option that 
can be loaded into lts.conf or some other config file we have.

Re: [Ltsp-discuss] ltsp and mythtv

2006-11-17 Thread gnyce
I have a PC (in the basement) that runs MythTV and LTSP.
Specifically, it runs mythbackend and mythfronted, and provides LTSP
services.  I run S-video plus audio cables running to my living room
TV upstairs to watch recorded shows.

I do not watch TV on the LTSP clients (have 2-3) - no desire to,
really.  I do not run mythfrontend on the LTSP clients either.

Yes to your last two statements/questions...

I would think sound is the trickiest part... has been for me.
Sometimes ESD works fine, esp. for certain apps (e.g. Gnome desktop
running amarok, rhythmbox, xmms, flash).  Sometimes it does not (e.g.
Gcompris, tuxpaint) - then the sound comes out of the TV  ;)

Not much help, probably, but there you go.

Subject: [Ltsp-discuss] ltsp and mythtv
To: ltsp-discuss@lists.sourceforge.net

HI,

I have a question about mythtv and ltsp. I'm planning to watch both
NTSC and HDTV on multiple client, mythfrontends.

Has anyone done this with ltsp?

Do you run mythfrontend as a local application on the client ltsp?

Or do you run multiple mythfrontend clients on the ltsp server and
have the X display exported back to each client.

I know for HDTV, I'll need a good graphics card and fairly fast client
computer that supports XvM...

Any pointers? Ideas?

Thanks,
Kevin

 Could you elaborate on how your script works?  I tried it, using your 
 instructions, but 
 the login screen just says User /usr/bin/autologin.pl| will login in 
 30 seconds and 
 when the 30 seconds runs out, the X server just restarts.
   
   
   
   
 Which version of GDM?  While 2.12 worked fine, there has been a nasty
 autologin/timed login bug starting in GDM 2.14.0.  I wrote a patch for
 the timed login which I think made it in for GDM 2.16.2.

 http://bugzilla.gnome.org/show_bug.cgi?id=340148


 
 
 
 Thanks Andrew.  As it turns out, the problem was a typo in my 
 autologin.pl script. 
 However, with GDM, the script is run for all client machines, and those 
 that aren't set 
 up for autologin just restart the client's X server, which works but is 
 annoying to look 
 at.  Do you know if there is any way in GDM  to set the autologin so 
 only specified 
 client machines even try to autologin?  With KDM I think this is 
 possible (haven't tried 
 it), but the greeter in KDM seems broken since any changes I make to 
 that don't show up 
 at the login screen.

   
   
   
 Hi Peter,

 I basically use the same method described here on the wiki.  The login 
 script checks the hostname, and if it's an undesired hostname, it 
 returns nothing.   When the script returns nothing, GDM should disable 
 the timed/automatic login systems. 

 http://wiki.ltsp.org/twiki/bin/view/Ltsp/WorkInProgress#Public_and_private_use_of_the_wo

 
 
 My script does more or less the same thing, though it's not as elaborate.  
 At the login 
 screen I see a line in the greeter that says User /usr/bin/autologin.pl| 
 will login in 
 X seconds.  If it's a machine that should autologin, it does so; if it's 
 a machine that 
 should not autologin, it appears autologin.pl still runs but returns an 
 invalid ID, and 
 so then the greeter resets and it appears that the X server may be 
 resetting as well, 
 and then it repeats the process.  What I'd like is for the autologin.pl 
 script to not 
 even run for those client machines that aren't setup for autologin,  Is 
 this possible 
 with GDM?
   
   
 Welcome to Gnome bug 340148.  Annoying, isn't it?  :)  That's exactly 
 the problem for which I provided a patch, so either upgrade GDM to a 
 patched version or apply the patch yourself.


 Andrew
 
 Okay, I just read the bug report (actually meant to do so yesterday when you 
 first sent 
 the link, but I had to leave work suddenly and forgot about it).  So, it 
 sounds like 
 your patch fixes the cosmetics of the greeter saying 'User 
 /usr/bin/autologin.pl| will 
 login in X seconds, but doesn't fix the more fundamental problem that 
 autologin 
 shouldn't even be attempted on clients that don't have a config for it on 
 the server, 
 correct?  That is, as you say in the bug report, GDM shouldn't even be 
 trying to 
 autologin staff machines, just those specified (the public clients), right?

 BTW, thanks for all your effort with Cameron and dealing with the problem so 
 far.
   
 In the end, I fixed both the cosmetic and the functional problems, so 
 now that timed login should be 100% OK, the remaining issue may be the 
 automatic login which I have not even tested.
 
 
 
 Andrew
 
I must have done something wrong.  I got your patch from the gnome bugzilla, 
installed 
the gdm SRPM, applied your patch, ran rpmbuild to make a new binary RPM, 
installed that 
with --force --replacefiles, rebooted the server, rebooted the client, and...I 
get the 
same behavior as before, where I see 'autologin.pl| will login in X seconds' 
and then it 
tried to login, fails, and loops back to the login screen, and repeats the 
whole process 
again.  I didn't get any errors when applying your patch, nor were there any at 
the end 
of rpmbuild, so I'm not sure what I missed.  Is there an existing patched 
version somewhere?

Re: [Ltsp-discuss] Printing Challenge

2006-11-17 Thread Alexander Hungenberg
Hello again,
thank you for those many answers. I will have a look at k12osn, thanks for the 
hint.

But the other two. I don't know if I understood you wrong but in my opinion 
the problem is, that a terminalsystem is logically only one pc. And from the 
terminal you haven't got access to the real system which ultimatly spools 
the printer. So if you set an environment variable, or some kernel options on 
the terminal, it won't affect the printing process on the server, because he 
even don't asks the terminal for anything.

Please correct me if I'm wrong (most likely I'm wrong) :) and thanks for your 
help

Alex

[Ltsp-discuss] Jammin 125 audio

2006-11-17 Thread Matt Schmandt
I have a Jammin 125 and am having problems getting the audio working. 
The server is running LTSP 4.2 on Gentoo.  I am getting the following
error when the client boots /dev/dsp no such file or directory. The
error message repeats many times and I confirmed that file is missing. 
In researching the issue I believe the problem is caused by it not
loading the driver properly.  Am I missing a module or do I have the
wrong ones?  I originally tried SMODULE_01 = cx5530 but I got the error
Module cx5530 not found.

I have the following in my lts.conf
   SOUND  = Y
   SOUND_DAEMON   = esd
   HOTPLUG= Y
#   SMODULE_01  = cx5530
   MODULE_01  = snd-cs5535audio
   MODULE_02  = snd-pcm-oss
   MODULE_03  = snd-mixer-oss

I then found
http://www.thesymbiont.com/index.php?option=com_contenttask=viewid=345Itemid=110
http://www.thesymbiont.com/index.php?option=com_contenttask=viewid=345Itemid=110
and installed the LTSP-esd-alsa package.  After installing the package I
get an error message stating it cannot find card '0'.  After that line I
get many more errors about no such device and unknown pcm default.

Any help would be appreciated.

 I have a question about mythtv and ltsp. I'm planning to watch both NTSC
 and HDTV on multiple client, mythfrontends.

 Has anyone done this with ltsp?

 Do you run mythfrontend as a local application on the client ltsp?

 Or do you run multiple mythfrontend clients on the ltsp server and have the
 X display exported back to each client.

 I know for HDTV, I'll need a good graphics card and fairly fast client
 computer that supports XvM...

 Any pointers? Ideas?

After LOTS of fiddling I could not make it work. Someone posted that they had, 
but when challenged to give details they were quiet. However
minimyth: http://www.linpvr.org/
does work beautifully and fits alongside LTSP without any problems. It took me 
an hour or two and all worked even HDTV.
I use ram root pxe boot

NFS root + myth = jitter so LTSP + myth = jitter and HD is unwatchable.
minimyth is smooth, easy and nice. I use intel+x86, nvidia+x86 and 
nvidia+x86_64. My lots of fiddling included the above HW.
