| 09:34 | <eu^for57-3-78-23> hello
| |
| 09:36 | Does some know how to set up the default x-session-manger for the ltsp client ? my version of ltsp is LTSP version: 21.01-1~ubuntu18.04.1
| |
| 09:38 | <alkisg> eu^for57-3-78-23: what's the output of : ls /usr/share/xsessions
| |
| 09:38 | <eu^for57-3-78-23> I tried update-alternatives --config x-session-manager and build a new image with ltsp image /
| |
| 09:39 | gnome.desktop gnome-flashback-compiz.desktop gnome-flashback-metacity.desktop gnome-xorg.desktop ubuntu.desktop unity.desktop
| |
| 09:39 | gnome desktop is Bold
| |
| 09:40 | i want to use gnome-flashback-metacity.desktop for the clients
| |
| 09:40 | <alkisg> Ah, you have many there :D What's your display manager? cat /etc/X11/default-display-manager
| |
| 09:40 | <eu^for57-3-78-23> it's /usr/sbin/gdm3
| |
| 09:44 | <alkisg> If you create a new user on the server, and try to login there, does it use the updated-alternatives value?
| |
| 09:44 | If it does, it should also use it on the ltsp clients
| |
| 09:44 | If not, try setting the value in custom.conf instead, 3rd solution there: https://unix.stackexchange.com/questions/367294/how-do-i-change-my-default-session
| |
| 09:47 | <eu^for57-3-78-23> this page is what i tried
| |
| 09:47 | the command update-alternatives --config x-session-manager
| |
| 09:47 | does not work on the clients ...
| |
| 09:48 | I tried also to build a new image after update-alternatives
| |
| 09:49 | for a reason that i don't understand the client use ubuntu.desktop by default
| |
| 09:52 | <alkisg> Please answer this question: does it work for a new user on the server?
| |
| 09:52 | Run: sudo adduser test
| |
| 09:52 | Then login as test. Do you get gnome-fallback?
| |
| 09:53 | <eu^for57-3-78-23> on the server it's working
| |
| 09:54 | antaresgades has joined IRC (antaresgades!~antaresga@ieocadiz.cd.ieo.es) | |
| 09:55 | <alkisg> For the new user, or for the existing user?
| |
| 09:56 | Because your "administrator" user might have stored its setting in .dmrc or in accountsservice
| |
| 09:56 | Or, try with the same user as you're trying on the clients
| |
| 09:56 | Don't try e.g. as "admin" on the server and as "student" on the clients, try the same user
| |
| 09:57 | <eu^for57-3-78-23> I tried an existing user
| |
| 09:57 | and it's working
| |
| 09:58 | <alkisg> OK nevermind, try the third solution that I said
| |
| 09:59 | I.e. put GDM3_CONF="DefaultSession=gnome-classic" in ltsp.conf, and run ltsp initrd
| |
| 09:59 | (or whatever other the name is; see the Exec line)
| |
| 10:16 | <eu^for57-3-78-23> ok it's not working on the server with a new user
| |
| 10:18 | <alkisg> Did you fix it with GDM3_CONF?
| |
| 10:18 | <eu^for57-3-78-23> GDM3_CONF="DefaultSession=gnome-classic" in which section of ltsp.conf ? [server] ?
| |
| 10:18 | <alkisg> Clients
| |
| 10:19 | <eu^for57-3-78-23> ok i will do it
| |
| 10:23 | ok, sorry not working either
| |
| 10:23 | <alkisg> Did you check the exec line of the session you want?
| |
| 10:24 | <eu^for57-3-78-23> no
| |
| 10:25 | <alkisg> Change gnome-classic to the name you want
| |
| 10:25 | <eu^for57-3-78-23> ok understood
| |
| 10:25 | i'll try
| |
| 10:26 | thnks a lot for your patience
| |
| 10:31 | danboid has joined IRC (danboid!~danboid@146.87.136.65) | |
| 10:35 | <danboid> Is there a better (more detailed) guide for configuring the network of an LTSP server than whats contained in the official LTSP docs, which is pretty minimal?
| |
| 10:38 | I'm also wondering what is the biggest known active LTSP installation (most clients)?
| |
| 10:39 | alkisg?
| |
| 10:41 | I think I'll get by with the official docs but just wondering if there was a more detailed guide covering more options ie google-auth, VLANs etc?
| |
| 10:42 | <alkisg> danboid: I'm not aware of other documentation
| |
| 10:43 | I have 500 users in 200 pcs
| |
| 10:58 | It's scalable, with 10x servers I could support 10x clients
| |
| 10:59 | <ogra> 500 users in 200 pieces is quite a big puzzle 😛
| |
| 10:59 | <alkisg> Hehe
| |
| 11:02 | <eu^for57-3-78-23> ok i've added this GDM3_CONF="DefaultSession=gnome-flashback-metacity" to ltsp.conf but it's not working :(
| |
| 11:06 | <alkisg> eu^for57-3-78-23: do you have epoptes installed? If so I could take a quick look
| |
| 11:07 | <eu^for57-3-78-23> yes I have epoptes
| |
| 11:07 | <alkisg> !vnc-edide
| |
| 11:07 | <ltspbot> vnc-edide: To share your screen with me, open Epoptes → Help menu → Remote support → Host: srv1-dide.ioa.sch.gr, and click the Connect button
| |
| 11:11 | <eu^for57-3-78-23> epoptes is not running on my machine
| |
| 11:11 | i try to start it
| |
| 11:15 | <alkisg> eu^for57-3-78-23: run this: x11vnc -connect alkisg.ltsp.org
| |
| 11:42 | Maybe they ignore it now; one solution would be to use lightdm
| |
| 11:42 | It will need more research OUTSIDE of ltsp to see what's gdm issue here :D
| |
| 11:42 | <alkisg_web> (ouch matrix syncing is very slow currently)
| |
| 11:42 | eu^for57-3-78-23: your setup seems correct; the gnome docs do not mention any global way to set the session anymore
| |
| 11:42 | You can keep on testing with new the new user on the server; if you find a way, you can then apply it easily to ltsp clients via ltsp.conf
| |

| |
| 11:43 | <alkisg_web> (ignore the duplicate messages they're due to matrix)
| |
| 11:45 | <eu^for57-3-78-23> ok
| |
| 11:47 | <alkisg> A quick workaround would be to copy the metacity.desktop file over the ubuntu.desktop file :)
| |
| 11:47 | Then it'll have no choice but to run the fallback session :D
| |
| 11:48 | eu^for57-3-78-23: put the user password there
| |
| 11:48 | To login and see if this works
| |
| 11:51 | So I mean something like this: POST_INIT_CP_SESSION="cp /usr/share/xsessions/gnome-flashback-metacity.desktop /usr/share/xsessions/gnome.desktop"
| |
| 11:51 | Anyway, time to go, back in a couple of hours...

| 12:16 | <brcisna[m]> alkisg: Hi Alkisg, Yesterday you gave me pointers on doing nat correctly ,in regards to a cellular plan i have started that only allows for one device to be connected to network( as a refresher). this is for our home internet. FYI. I did do 'ltsp dnsmasq' .then switched the LAN nic to 192.168.67.1 . Unfortunately the provider (Visible) is still detecting a second machine,,,thin client connected to the sever . id di try also to do masquerade
| |
| 12:16 | in iptables, to the wwan0 interface as well,and this didnt make any difference.
| |
| 12:20 | Am wondering if i setup an pfsense box with the modem in it,with nic,,then connect the ltsp server to pfsense if it may do a better job ? Also as a sidenote, i was reading up on CGNAT ,,which i have never checked into. There were two commerical grade softwares that said you could not use their software on a machine that was UEFI enabled as some of the functionality would not work? This ltsp server is installed as UEFI. just throwing that
| |
| 12:20 | out. I know this is defintely noy ltsp related. Thanks
