| 15:19 | <Kamgha> sebd: SSH connection is good. it accepts password for user opens session then receives a disconnect by user a couple seconds later
| |
| 15:21 | <sebd> strange

| 15:22 | <sebd> 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
| |
| 15:24 | Kamgha_ has left IRC (Kamgha_!40b90e12@gateway/web/freenode/ip.64.185.14.18, Ping timeout: 250 seconds) | |
| 15:24 | <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
| |
| 15:31 | Freejack 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)
| |
| 16:27 | mikkel has left IRC (mikkel!~mikkel@mail.dlvs.dk, Quit: Leaving) | |
| 16:29 | <Kamgha> 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

| 17:07 | <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> http://manpages.ubuntu.com/manpages/trusty/man5/lts.conf.5.html
| |
| 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
| |
| 17:11 | Parker955_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
