Kamgha: what about tail -f /home/yourUser/.xsession-errors ?
15:23
<Kamgha>
no xsession-error file
15:23
<vagrantc>
thin client or fat client? thin clients require a desktop environment installed on the server.
15:23
<Kamgha>
thin

<Kamgha>
it's the normal ubuntu ltsp install. is there another package i need to add?
15:25* vagrantc doesn't know what normal is
15:25
<vagrantc>
is ldm-server installed?
15:25
are there /usr/share/xsessions/*.desktop files?
15:26
<Kamgha>
ldm-server is install
15:26
installed*
15:26
no i don't have the xsessions directory....
15:27
<vagrantc>
i don't see how you could have ldm-server installed, but not actually have any sessions installed...
15:27
either ldm-server has broken dependencies on ubuntu, or there is something very broken with your install
15:27
<Kamgha>
lemme try reinstalling, i've done lots of random changes trying to get this to work
15:29
<vagrantc>
well, first, check that ldm-server actually depends on a desktop environment
15:30
oh, it only recommends desktop environments
15:30
Kamgha: did you install with --no-install-recommends ?
15:30
is this in fact not ubuntu but some ubuntu derivative?
15:31
<Kamgha>
reinstalling ldm-server gave me the xsessions directory now
15:31Freejack has joined IRC (Freejack!~Freejack@unaffiliated/freejack)
15:31
<Kamgha>
it's ubuntu 16.04
15:31
<vagrantc>
sounds like you might have had recommends turned off at some point
15:32
<Kamgha>
well time to update image and see how it goes
15:32
<vagrantc>
installing packages on the server shouldn't require rebuilding the image
15:32
unless you're using ltsp-pnp
15:33
but if you're using ltsp-pnp, i'd be surprised that you ended up without dektop environments.
15:33
did you do an ubuntu server install, rather than an ubuntu desktop install?
15:34
<Kamgha>
yes, server install
15:35
<vagrantc>
generally, LTSP servers need a full desktop environment
15:35
so installing a the desktop variant is a better starting point
15:36
<Kamgha>
hmm ok
15:36
<||cw>
I still do a netinst and then install whatever-desktop package :)
15:37
mostly because I have PXE booting installers that autoconfig my local apt-cache
15:37
<vagrantc>
Kamgha: it is, essentially, a server that serves up desktops :)
15:38
sure, if you're familiar with what you're doing, you can do it however you like
15:38
<Kamgha>
yeah, even reinstalling ldm-server didn't fix the error :/
15:38
<vagrantc>
but for a first install, generally best to go with the standard recommendations :)
15:38
<||cw>
these days, with a few exceptions, the only difference between a desktop and server install is the packages you install
15:39
<vagrantc>
Kamgha: somehow it's not pulling in recommends.
15:40
"
15:40
The `Recommends' field should list packages that would be found
15:40
together with this one in all but unusual installations.
15:40
"
15:40
which is exactly how ldm-server is configured
15:40
if you remove and install ldm-server, does it pull in recommends?
15:41
e.g. desktop environments?
15:42
<Kamgha>
removing and installing again just has ldm-server :/
15:44
oh well this was new.. just tried logging into client. Xsession: unable to launch "gnome-fallback" X session --- "gnome-fallback" not found; falling back to default session. so it's not finding ldm at all?
15:44
<sebd>
Kamgha: LDM works but it cannot start the gnome session
15:46
<vagrantc>
Kamgha: my guess is your installation is configured to not install recommends
15:46
Kamgha: is this still a server install, or a desktop install?
15:46
<Kamgha>
server
15:47
<vagrantc>
i would recommend installing the desktop variant.
15:48
<Kamgha>
ok
15:48
<vagrantc>
or looking through /etc/apt/apt.conf.d/ for files that disable installation of recommends
15:48
but who knows what other broken settings are in the current configuration
15:49
<Kamgha>
might be easier to just fresh install desktop
15:49* vagrantc nods
15:49
<Kamgha>
though i'm fairly certain recommended are getting installed
15:50
doing the original ltsp package install it listed more than just ltsp.. so i know it installed some stuff correctly

16:01
<vagrantc>
seems unlikely, if installing ldm-server isn't pulling in any additional desktop packages, and there are no files in /usr/share/xsessions/*.desktop
16:01
but what do i know
16:08
<Kamgha>
decided to install gnome. it pulled a bunch of recommended packages. and... i logged in
16:24
reinstalling ldm-server and installing gnome seemed to do it
16:24
<vagrantc>
something is really odd
16:25
<Kamgha>
wondering if i had issues with the original ldm-server install is all i can think of
16:26
<vagrantc>
no idea
16:27
the one difference between ldm-server on debian and ubuntu is the ordering of the recommends ... maybe gnome-session is no longer present in ubuntu?
16:27
or gnome-session doesn't actually pull in a .desktop file (though that would seem odd)

well i've got another minor issue that i'd got to fix now that i'm logged in, but thanks for helping. pointed me in the right direction to get it working

<julienfayad>
Hello there, quick question in regards to the /etc/fstab file (as it seems it is generated by ltsp on FAT clients)
17:08
the /usr/share/ltsp/init-ltsp.d/50-rm-system-services file operate it’s test on the client file I guess, not the server file ? If yes how can I edit the fstab file for an ltsp client ? Even better for all ltsp clients of a given group ?
17:09
<quinox>

17:09
FSTAB_0..FSTAB_9
17:09
string, default unset
17:09
Complete lines to add to /etc/fstab, for example:
17:10
<julienfayad>
that was fast, thanks quinox
17:11Parker955_Away has joined IRC (Parker955_Away!~parker@2607:5300:60:8425::2d62:a8e6)
17:11
<julienfayad>
So if I understand it well, if I put that inside a specific section (i.e [Dept1]), I can then have FSTAB applied to a selection of clients only, the ones belonging to [Dept1], right ?
17:14
<vagrantc>
julienfayad: the [] matching is for specific hosts, though you can use wildcards
17:15
julienfayad: you can also specify [foo1] LIKE=Dept1 [foo2] LIKE=Dept1
17:15
<julienfayad>
yeah that’s what I was seeing
17:16
<vagrantc>
you can also do [dept*] if the hostnames are configured ... although hostname handling in ltsp is a bit hackish
17:16
or maybe [dept1-*]
17:17
<julienfayad>
I guess for my specific need I’ll have to use both the ltsp conf for specific fstab content and a script that runs at login
17:17
as I have some nfs shares which are for all and some others for some users only
