| 19:46 | <ta2fb> alkisg: you were so helpful yesterday, I have another question - is there a simple way to enable screen lock? it doesn't seem to start because gdm isn't running
| |
| 19:47 | <alkisg> ta2fb: remind me, which de are you using?
| |
| 19:49 | By default, the user password isn't transferred to fat clients
| |
| 19:49 | So if you locked, it wouldn't be possible to unlock
| |
| 19:49 | Some DEs are clever enough to see that and prohibit locking
| |
| 19:49 | !lock
| |
| 19:49 | <ltsp> (lock [<channel>] <key>) -- Locks the factoid(s) associated with <key> so that they cannot be removed or added to. <channel> is only necessary if the message isn't sent in the channel itself.
| |
| 19:49 | <alkisg> !hash
| |
| 19:49 | <ltsp> I do not know about 'hash', but I do know about these similar topics: 'LDM_PASSWORD_HASH', 'ROOT_PASSWORD_HASH'
| |
| 19:49 | <alkisg> !LDM_PASSWORD_HASH
| |
| 19:49 | <ltsp> LDM_PASSWORD_HASH: LDM_PASSWORD_HASH=True in lts.conf saves the password hash to /etc/shadow on login, so that the users can unlock the screensaver etc. If they happen to change their password though, that only takes effect until logout.
| |
| 19:49 | <alkisg> Try this one ^
| |
| 19:50 | <ta2fb> I do have LDM_PASSWORD_HASH=true
| |
| 19:50 | <alkisg> And which DE?
| |
| 19:50 | (desktop environment)
| |
| 19:50 | Ubuntu, MATE, Lubuntu etc?
| |
| 19:50 | <ta2fb> the default, ubuntu
| |
| 19:50 | <alkisg> So, gnome
| |
| 19:50 | <mwalters> fur keeps you warm
| |
| 19:50 | oops, wrong channeel ;)
| |
| 19:51 | <alkisg> For sure
| |
| 19:51 | :)
| |
| 19:51 | <mwalters> fur sure
| |
| 19:51 | <alkisg> :D
| |
| 19:51 | ta2fb: and what happens if you try to lock screen on the client?
| |
| 19:51 | No response at all? Any error message?
| |
| 19:52 | <ta2fb> nothing happens, get this message in /var/log/syslog
| |
| 19:52 | Couldn't lock screen: Cannot invoke method; proxy is for a well-known name without an owner
| |
| 19:52 | and proxy was constructed with the G_DBUS_PROXY_FLAGS_DO_NOT_AUTO_START flag
| |
| 19:52 | which I googled which has something to do with gdm being stopped
| |
| 19:52 | I started it but that broke things as you could imagine
| |
| 19:53 | <alkisg> Oh yeah don't start gdm, this won't be ltsp anymore
| |
| 19:53 | So, the user can properly authenticate, right? For example, on the client, if you open a terminal and run `su - $USER`, you can re-login as the user. Correct?
| |
| 19:54 | <ta2fb> yes, and I also enabled ssh and that works as well
| |
| 19:54 | <alkisg> It would be a shame if gnome doesn't work without gdm. For example, ubuntu had lightdm for ages.
| |
| 19:54 | <ta2fb> yea
| |
| 19:55 | <alkisg> Open a bug report in ltsp; maybe sometime someone will have a look at it
| |
| 19:55 | Here I maintain 1000+ schools, but we're using MATE
| |
| 19:55 | I plan to switch them to gnome later on for Ubuntu 20.04
| |
| 19:55 | !ltsp-bug
| |
| 19:55 | <ltsp> ltsp-bug: To file a bug report for upstream LTSP, go to https://bugs.launchpad.net/ltsp
| |
| 19:55 | <ta2fb> ok, sounds good
| |
| 19:56 | I will file a report and will play around with some things
| |
| 19:56 | we had to do some funky stuff on 16.04 before so I will see how that solution works and will let you know
| |
| 19:56 | <alkisg> So for the moment, ltsp-related mate bugs get solved more quickly; while for other DEs, not so much, unless someone tests and comes up with a solution
| |
| 19:57 | * alkisg tried gnome recently and it needed 1 GB just for the DE; we have clients with 1 GB that we expect to run firefox too :) | |
| 19:57 | <alkisg> It became horribly bloated with the "moving the DE to javascript" thing
| |
| 19:58 | <mwalters> (not LTSP specific) while we're on the subject of DEs and screensaves... how can I make a system wide idle-time out for mate/ltsp?
| |
| 19:58 | I put a file, `screen-timeout` in /etc/dconf/db/local.d
| |
| 19:58 | <alkisg> In general, you run dconf watch / in a terminal, and change whatever setting you want
| |
| 19:58 | that way you see the related gsetting
| |
| 19:59 | <mwalters> and put in [org/mate/desktop/session]\nidle-delay=15
| |
| 19:59 | but no luck
| |
| 19:59 | <alkisg> Then, you can either put defaults in /usr/share/glib/schemas, or mandatory settings in /etc as you said
| |
| 19:59 | <mwalters> yeah, I figured that part out
| |
| 19:59 | np just hoping you knew off the top of your head, I'll keep digging
| |
| 20:00 | <ta2fb> you mean screen lock?
| |
| 20:00 | ltsp-chroot
| |
| 20:00 | | |
| 20:00 | mkdir -p /etc/dconf/db/local.d/locks

| |
| 20:00 | <ta2fb> oops
| |
| 20:00 | <alkisg> Hehe, that will teach you to flood in freenode :P
| |
| 20:00 | !pastebin
| |
| 20:00 | <ltsp> pastebin: try !paste
| |
| 20:00 | <ta2fb> did you get all that?
| |
| 20:00 | <alkisg> !paste
| |
| 20:00 | <ltsp> paste: the LTSP pastebin is at http://ltsp.pastebin.com. Please paste all text longer than a line or two to the pastebin, as it helps to reduce traffic in the channel. Don't forget to paste the URL of the text here.
| |
| 20:00 | <mwalters> no, I'd appreciate it if you co uld paste bin it, though. Thanks!
| |
| 20:01 | <ta2fb> that link doesn't resolve for me
| |
| 20:01 | <mwalters> I figured i had an older way to do it or something and I just couldn't figure out the magic words to google it
| |
| 20:01 | spaced0ut has left IRC (spaced0ut!~spaced0ut@unaffiliated/spaced0ut, Ping timeout: 246 seconds) | |
| 20:01 | <mwalters> doesn't seem like it's common to have multiuser GUI based boxes
| |
| 20:01 | <alkisg> https://wiki.gnome.org/Projects/dconf/SystemAdministrators
| |
| 20:01 | This is the guide ^
| |
| 20:02 | <mwalters> Thanks!
| |
| 20:02 | <alkisg> "Lockdown is supported by creating a 'locks' subdirectory in the keyfile directory (ie: /etc/dconf/db/local.d/locks)." etc etc
| |
| 20:02 | <mwalters> oh, I missing the locks
| |
| 20:03 | Great stuff, thanks!
| |
| 20:03 | <alkisg> np
| |
| 20:09 | <ta2fb> it looks like http://ltsp.pastebin.com doesn't resolve for me, any reason why that may be the case?
| |
| 20:13 | <mwalters> doesn't for me either

| 20:25 | <ta2fb> alkisg: you can close this bug: https://bugs.launchpad.net/ltsp/+bug/1810330
| |
| 20:27 | mwalters: this will lock the screen after a time you specify - won't do a logout
| |

| |
| 20:27 | ignore the fact that the comment time doesn't match the actual value sent
| |
| 20:32 | <alkisg> ta2fb: you can close it, there's no "bug maintainer"
| |
| 20:33 | <mwalters> oh, derp
| |
| 20:33 | I also put it on the ltsp server... not the chroot
| |
| 20:33 | My ltsp boxes are all VMs now... with chroots...
| |
| 20:33 | I can't keep up with this web of abstractions I've sewn myself in to
| |
| 20:34 | <ta2fb> alkisg: would I mark the bug as fix committed?
| |
| 20:35 | <||cw> mwalters: I know that feel
| |
| 20:36 | in testing stuff I had a usb-serial device passed to a vm guest that netbooted to ltsp and pass the port to xfreerdp to a terminal server
| |
| 20:37 | also all my servers are vms in a cluster. it's the only way to live these days
| |
| 20:41 | <ta2fb> non-important question - is there a way to change the initial login screen to add a banner/text?
| |
| 20:55 | <mwalters> ta2fb: I'm pretty sure there's something on ltsp.org about that
| |
| 20:57 | http://wiki.ltsp.org/wiki/Tips_and_Tricks/User_Experience#LDM_Greeter_and_Theme
| |
| 20:58 | this is cryptic, but should probably point you in the right direction
| |
| 20:58 | specifically, the very last line in that section
| |
| 21:03 | <ta2fb> cool, thanks, mwalters
| |
| 21:09 | <alkisg> ta2fb: "fix committed" means that code was added in ltsp to fix it
| |
| 21:09 | So no, it should be "invalid", which means "not a bug in the ltsp code"
| |
| 21:09 | I set it to invalid.
| |
| 21:09 | assignee is the one that will write the ltsp code that will fix the bug
| |
| 21:10 | So it should be left blank, since it wasn't a bug
| |
| 21:19 | <ta2fb> oh, ok, thank you for clarifying
