work_alkisg, Hi :) sorry the internet got disconnected
09:18
Okay first thing is I want to know
09:18
is there anything I need to install on thinclient ?
09:18
<work_alkisg>
No
09:19
<gagan>
work_alkisg, it has some "Similar to windows xp" UI
09:19
its an HP thinclient
09:20
Okay :) I don't need to install anything on the client itself.
09:20
It means I have to install the ltsp on my Server which in this case is my laptop
09:20
<work_alkisg>
Yes
09:20
<gagan>
correct ?
09:20
I see
09:44
work_alkisg, and on my server
09:44
I need to install
09:44
sudo apt-get install ltsp-server-standalone
09:44
and it says now create an ltsp client
09:44
what is the use of this client image

matthias_: you might have better luck putting virtual box on a stand alone machine, and use the FAT Clients to connect remotely to the VM with RDP/X11/NX/SSH
13:31
also, why is this: https://bugs.launchpad.net/unity-settings-daemon/+bug/1320286 NOT an issue with LTSP project if it only happens with LTSP Fat Client?

championofcyrodi: crap like that is why my next fresh install is not going to be ubuntu. all they seem to do anymore is shuffle and twist unless it's a security vuln.
14:25
they still don't see the intel video driver not offering true 720p on a 11" laptop as a problem, even though the windows driver does. specifically, for mirroring to projectors.

14:46
<||cw>
except for that one time when they rolled back a perl version and didn't roll back all the packages that depended on the newer version
14:46
it'll likely be debian proper, or maybe mint
14:48PhoenixSTF has left IRC (PhoenixSTF!~rudiservo@78.29.147.214, Quit: Leaving)
14:49
<vagrantc>
mint inherrits a lot of what ubuntu does, for better or worse, just by virtue of using mostly ubuntu packages without modification
14:50
<||cw>
I know. but there is also modification
14:50
ubuntu also uses a lot of debian packages without modification as well
14:50
<ogra_>
yeah, they tend to change libs in mint without bumping the ABI
14:51
(while they in fact bumped it ... launchpad is full of fallout bugs from that)
14:51
<vagrantc>
||cw: not actually true, they rebuild all of them. mint doesn't.
14:51
<||cw>
IMO, rebuild isn't a modify
14:51
<vagrantc>
it is if you're using a different compiler with different defaults
14:52
<ogra_>
or a newer libc
14:52
<||cw>
how much does that really matter?
14:52
sometimes a lot, but mostly...
14:53
<vagrantc>
bugs are only problems when they are problems.
14:53
they're fine all the other times.
14:53
<ogra_>
it does matter for compatibility ... you cant just use debian packages in ubuntu ...
14:53
and it shouldnt be possible for mint to use ubuntu packages since they change underlying libs without rebuilds
14:53
which causes all sorts of issues
14:53* vagrantc didn't know mint changes ABI without marking it as such
14:54
<ogra_>
they patch gtk and stuff
14:54
if they would mark their API/ABI break as they should the ubuntu packages wouldnt be installable pproperly
14:54
but to still have them installable they dont ...
14:55* vagrantc sighs
14:55
<ogra_>
which causes broken binary behavior at times
14:55
<||cw>
but the issues with ubuntu isn't so much bugs, but choices, and redirection, and buck-passing
14:55
<ogra_>
(this is what all that "canonical asked mint to license binaries" was about ... )
15:10* ben_nabiy sighs...

vagrantc: Hello!
15:18
vagrantc: Do you have any thoughts as to why firefox, thunderbird and pidgin would stop working?
15:23
<vagrantc>
they release too early, and too often?
15:26
<ogra_>
lol
15:26
<ben_nabiy>
hah!
15:26
vagrantc, too common sense...
15:28* ogra_ would suggest reading logs FWIW
15:28
<ogra_>
probably ~/.xsession-errors has some info
15:29
<ben_nabiy>
ogra_ do you mean your conversation about mint ?
15:29
or do you mean system logs?
15:30
<ogra_>
ben_nabiy, no. your question about FF, TB and pidgin
15:30
<ben_nabiy>
heh, system logs do not produce much, I did not think about .xsession-errors. thanks :)
15:30
<ogra_>
:)
15:32
<ben_nabiy>
nothing there
15:33
I am running strace on thunderbird and pidgin to see if I can find what is locking them up, but it makes the execution of them so much slower...
15:34
thunderbird is in uninterruptible state, but kill -9 works on it
15:36mealstrom has joined IRC (mealstrom!~Thunderbi@46.63.63.163)
15:46
<ben_nabiy>
any thoughts on hard drive issue? If it is having trouble reading the particular part of the hard drive, would it cause uninterruptible status?
15:47
(process:12245): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
16:04
hmm pidgin works now.

Hi bennabiy, hi all
17:52
<bennabiy>
alkisg: Did you try out 17 for your input issue?
17:53
<alkisg>
bennabiy: it worked ok with regards to layout switching, it did have a couple of other minor issues, and I'm still not sure what's the best way forward with the schools here...
17:54
We might stick to 12.04 with the old xorg and the new trusty kernel, and then switch to debian+mate
17:54
It depends on a lot of things, I don't know yet what we'll do

<Hyperbyte>
alkisg, hi... what's generally issue if someone gets initramfs error?
18:43
That's what someone is telling me... I can't recall the exact error.
18:44
<vagrantc>
usually misconfigured dhcp
18:44
though there was a recent bug in ubuntu that caused problems with NBD
18:44
but essentially, it means it can't mount the root filesystem
18:45
<bennabiy>
Hyperbyte, depends on the point, but I remember encountering it a lot when NBD needs to be force-reload ed
18:46
<Hyperbyte>
bennabiy, this disconnects clients, right?
18:47
<bennabiy>
yes
18:48
<Hyperbyte>
I've had this before I think, with mistaches between PXE boot trying to look for NBD mount "ltsp_i386" and NBD mount name being "/opt/ltsp/i386" in the nbd config
18:48
*mismatches
18:48
<bennabiy>
The way to tell if it is nbd related is to clear the plymouth screen and see if it is coming up with an error trying to find root device
18:49
<Hyperbyte>
I'm not physically there.
18:49
Which doesn't help.
18:49
<bennabiy>
hmm
18:49
ssh and then virtualbox terminal pxe boot?
18:49
s/ssh/x2go/
19:01
<alkisg>
Hyperbyte: what version? 14.04?

<championofcyrodi>
I have had to bounce the nbd-server twice in the last 40 days...
19:11
(14.04)
19:12
in 12.04 I was getting weird issue on i386 image in that the nbd size was being reported as [1-5] petabytes in size, and that i needed to get a 64 bit machine to support.
19:13
which didnt make any sense because the ltsp server only had a 1.2TB /
19:14
<alkisg>
Just a mishandled negotiation, nothing serious... :)
19:14
Probably a wrong nbd configuration
19:15
!learn nbd-trusty-bug as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1330671

The operation succeeded.

alkisg, yeah... strange is that person rebooted client again and problem went away

im not entirely clear on something. in terms of the applications and software that I want to be able to run on thin clients, is this supposed to be installed in the thin client .img, or does it use whats on the host machine? it seems like it uses a mix. is the .img just supposed to be bare bones or should one include all the software in there
