<Royale_AJS>
How do I convert thin clients to fat ones in Edubuntu?
01:18
<vagrantc>
install a desktop in the chroot
01:19
make sure they have enough ram
01:19
i *think* something like: ltsp-chroot apt-get install edubuntu-desktop
01:19
Royale_AJS: that should do the trick ... not quite familiar with the ubuntu package names
01:19
so may have to adjust accordingly
01:22
<Royale_AJS>
Let me see what I can do a sec.
01:23
<vagrantc>
rebuild the image, too ... ltsp-update-image
01:23
i'd also recommend exploring ltsp-pnp methods:
01:23
!ltsp-pnp | echo Royale_AJS
01:23
<ltsp>
Royale_AJS ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp

512M RAM on the clients only...but I'm having major performance issues when more than 10 machines load up on the server.
01:25
Server is on a 1GB switch but can't seem to run over 130MBit/sec out of it?
01:26
<vagrantc>
any video will saturate even a 1GB connection with a small number of thin clients
01:26
anyways, gotta head out
01:26
good luck!
01:26* vagrantc waves

!video
01:26
<ltsp>
I do not know about 'video', but I do know about these similar topics: 'video-without-flash', 'video-test'
01:26
<vagrantc>
!video-test
01:26
<ltsp>
video-test: You can test your network and graphics drivers with http://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_640x360.m4v. It's 640x360@24, which means it needs 66Mbit, which means you should be able to view it without dropped frames in e.g. 12 clients simultaneously

Hello!
07:37
Does anybody know if Epoptes can be installed in a Fedora 24 without too much pain?
07:38
<alkisg>
Hello alvaro

<alkisg>
I think there's an opensuse rpm that can be used in fedora too
07:39
But I've never used fedora, so...
07:42
<alvaro>
thanks, alkisg
07:43
I've never used fedora until this year, all the computers in the high school work with it
07:43
And I need to convince the IT crew to install epoptes...
07:44
I think this is the page, thank you very much: http://software.opensuse.org/package/epoptes
07:45
<alkisg>
Yes, probably... I found this: https://build.opensuse.org/package/show?project=home%3Albssousa%3Aepoptes%3Adaily&package=epoptes
07:45
under fedora 24 => unsafe builds
07:46
So the binaries are there: https://build.opensuse.org/package/binaries/home:lbssousa:epoptes:daily/epoptes?repository=Fedora_24
07:47
<alvaro>
I'll try both later in a virtualized environment, thanks
07:47
<alkisg>
I've no idea what would be the proper way to use the binaries though, e.g. install them or add them as a repository, ask in #fedora if you have questions on how to use them
07:47
You're welcome

install both kiwi-image-ltsp-13.2.1-52.20.noarch.rpm and kiwi-image-ltsp-boot-13.2.1-52.20.noarch.rpm

then rcklaoe restart

uninstall old ones?

Hello! I have an Ubuntu LTSP server that I updated to 16.04, the clients when I updated 4 out of 6 are having video display problems, change resolution to 1280x1024. I tried adding resolution to lts.conf with no avail.. I tried adding

<MeLLy>
Can anyone help me? We are deploying an office and have a weird issue. We are on Debian 8. Some terminals will boot while some won't. In the logs it says this: Sep 20 08:05:14 magnus in.tftpd[6876]: sending NAK (1, File not found) to 172.30.70.105
13:03
Its happening on (2) terminals. All others boot just fine. All the directives in lts.conf are the same for all terminals. I know that error points to a tftp issue but it's not obvious to me what the issue would be.
13:10
<cyberorg>
al-geo, here is the background of your issue https://github.com/openSUSE/kiwi/pull/596
13:12
<al-geo>
yep that looks like me
13:28forum has joined IRC (forum!~Icedove@194-96-5-19.adsl.highway.telekom.at)

<alkisg>
MeLLy: check TFTP/ltsp/i386/pxelinux.cfg/01-mac-address for those terminals
13:42
theller: did you create a new chroot for 16.04</
13:42
?
13:43
<theller>
If you mean a new client image in opt, yes
13:44
I just took out the video card and used the onboard graphics and it works
13:45
<alkisg>
OK
13:47
<theller>
I checked the xorg.log of the client that works and one that doesen't. the broken one does not show 1280x1024@60Hz
13:48
<alkisg>
I'm confused, when you let the onboard graphics work, was that "problem solved", or, "i need help in making the pci-e one work"</
13:48
?
13:49
<MeLLy>
I don't see anything underneath pxelinux.cfg called 01-mac-address
13:50
<alkisg>
MeLLy: do you see anything starting with 01- there? or only ltsp, default etc?
13:50
<MeLLy>
I only see default, ltsp, ltsp-*
13:50
Nothing with 01
13:51
<alkisg>
OK
13:51
What do the terminals that don't boot display?

It eventually gets to a point where it says "/bin/sh: can't access tty: job control turned off (intramfs)"
13:55

MeLLy: it looks like your initramfs doesn't have the driver for this network card
14:00
MeLLy: can you load debian in that pc, with e.g. a live usb stick, so that you see if it works, and with what driver</
14:00
?
14:00
<MeLLy>
Really? That's interesting. We have the same exact type of terminals working for others so there shouldn't be a difference in nics
14:01
<alkisg>
Do you see those module errors in the other pcs?
14:01
<MeLLy>
No I don't
14:01
Only two of them
14:01
<alkisg>
On the other pcs, what\s the output of lspci -nn -k | grep -A 2 Ethernet ?
14:01
locally
14:01
(with screen_02=shell, or with epoptes, or with ssh...)
14:01
!localxterm
14:01
<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.
14:02
<alkisg>
....or like that ^

cyberorg yesthe same
14:53
<cyberorg>
how are clients connected to the server, try direct connection without any switch in between to rule out connection issue
14:54
also check rpm -qa|grep ltsp the packages should be 52.20 version
14:54
i've tested real hardware as well as virtualbox client, works for me
14:59
<al-geo>
wow cyberorg direct connect helpd
14:59
whats going on?
14:59
<cyberorg>
something wrong with your switch
14:59
<al-geo>
you are greatest
15:00
<cyberorg>
or you may have another dhcp server in the network which interferes with ltsp one, try proxy mode edit /etc/dnsmasq.d/kiwi-ltsp.conf
15:00
then rcdnsmasq restart
15:01
if the client still boot in proxy mode then you got another dhcp somewhere

theller: the onboard video probably is intel, and it will perform better than nvidia with the default nouveau driver
17:02
theller: if you're looking for 3d support on the nvidia card, you should install the nvidia drivers in the chroot, but it gets messy if you have different clients
17:04
theller: if you just want to enforce a video mode, start with putting the output of `xrandr` to pastebin
17:04
and also pastebin the client's xorg.log
