<ogra_ac>
what did you do to break it ?
10:50
<Kyle__>
Uzzi: Did you do a clean install, upgrade in place? Real system or chroot?
10:51
<Uzzi>
clean install
10:51
in ltsp client
10:51
<Kyle__>
Uzzi: So clean chroot install.
10:52
Uzzi: I don't have any classes in one of my labs today. I can try seeing how well a 10.04 to 10.10 update works in chroot.
10:54
<alkisg>
/root/etc/hostname? Are you sure that's the path? Is this inside the initramfs?

alkisg: I'm on my first cup of coffee, thought you said holga.
10:56
<ogra_ac>
*like
10:56
or that :)
10:56
<alkisg>
No I just repeated the "Hola" from Uzzi signature

Ugh. I'm teaching a course next semester, and I just found out how much the book costs.
13:52* Kyle__ wouldn't feel so guilty about it if the book was decent.
13:54
<crazed>
hm is there a way to set the default firefox home page for all users in ltsp?
13:54
<Kyle__>
crazed: I believe you can do that through your /etc/skel, but I don't know about after the fact...
14:00pete_ has joined #ltsp
14:02
<crazed>
seems i can make some changes in /etc/firefox/pref/firefox.js hm
14:05
<Kyle__>
crazed: Oh duh, yea that would work as well :)
14:05
Sometimes the obvious escapes.
14:06
<crazed>
doesn't look like they are getting applied though hm
14:07
<Kyle__>
crazed: did you blow away their old settings?
14:07
<alkisg>
crazed: try in /etc/firefox-3.0/pref/user.js
14:09
(or if that fails, in /usr/lib/firefox-3.6.12/defaults/pref - firefox changes the location on each new version :()
14:12
<crazed>
ah!
14:12
i had to blow away my current profile
14:12
ok makes sense now
14:12
<Kyle__>
yea :) changes there only affect newly created profiles.
14:12
<alkisg>
You can also use lockpref() to force settings
14:12
i.e. mandatory
14:13
lockPref() => mandatory settings, user_pref() => default settings
14:14
<robehend1>
alkisg: Ooo, where I can set that? I'd like to use that instead of screwing with sabayon
14:14
<alkisg>
robehend1: see the paths above, an example line is: lockPref("browser.startup.homepage", "http://www.google.com");
14:16
Firefox keeps changing its configuration directory. Ah, on my lucid, /etc/firefox/pref/user.js works
14:16
(need to create it)
14:22* vagrantc is also fighting with customizing firefox
14:23
<vagrantc>
there doesn't seem to be any sane way to set a default but allow the user to change it, without upgrades potentially asking questions about changed conffiles
14:26
as user.js overrides the defaults set in prefs.js ... and /etc/firefox/prefs/all-*.js overrides everything ... yet with both those options it allows the user to change them through the UI ... the changes just get overriden on the next start.
14:26
<alkisg>
vagrantc: /etc/firefox/pref/user.js isn't a conffile... the problem is that it's not a consistent path :(
14:26
lockPref forces the settings, it even disables the preferences UI for that control
14:27
<vagrantc>
alkisg: yes, but user.js overrides the user's prefs.js, which is where changes through the UI are saved
14:27
<alkisg>
So? If an admin wants mandatory settings, what does he care about prefs.js?
14:27
<vagrantc>
so a user *can* change it by deleting user.js ... but that's a non-obvious way to fix it
14:28
alkisg: i don't want mandatory settings in this case, i want defaults.
14:28
<alkisg>
How can the user access /etc? It's read-only....
14:28
Ah
14:28
<vagrantc>
it's copied into the user's profile
14:28
<alkisg>
OK, the defaults are meant to be changeable :)
14:28
<vagrantc>
so there's no way to seed a default that allows the user to change it later in a sane manner
14:29
at least, no way that i've figured out
14:29
you can tweak /etc/firefox/defaults/prefs.js is the closest, but that's a conffile ...
14:29
<alkisg>
Hmm let's get over that again. If I set `user_pref("browser.startup.homepage", "http://www.google.com");` to set a default for new users in /etc/firefox/pref/user.js, what are the downsides?
14:30
<vagrantc>
alkisg: the user.js gets copied to the user's homedir, and overrides the defaults changed through the UI
14:30
until the user deletes it
14:30* alkisg tries that...
14:30
<vagrantc>
i tried this stuff on lucid just the other day, testing all the possibilities
14:31
at least, all the possibilities i could come up with.
14:31
the good news is it's easy to force defaults, if that's what you want to do :)
14:31
or mandatory, or whatever ...
14:32
<alkisg>
vagrantc: nope, defaults work fine here
14:32
user.js is NOT copied to the user. It provides defaults, and the user can later change them in his prefs.js
14:32
The user does not have a user.js in his home dir
14:33
<vagrantc>
didn't work that way for me.
14:33
alkisg: did you try this with a new user?
14:33
or by manually removing the user's profile(s)
14:33
?
14:33
<alkisg>
I just deleted the homepage pref from my prefs.js
14:33
Let me test with a new user, brb...
14:34
Or wait - i'll fire up a vm
14:34
<vagrantc>
and then apparently, for some settings, firefox uses a *completely* different configuration file and syntax ... ugh.
14:35
<alkisg>
I've tested that extensively in 9.04, everything worked fine, I could lock or set defaults for all settings in the preferences UI
14:35
The only downside was the constant changes in where to put the user.js file...
14:35
<vagrantc>
yeah, it's crazy.
14:35
impossible to find good documentation, since it's highly version-dependent.
14:36
<Gadi>
we talking about LTSP ;)
14:36
:)
14:36
<vagrantc>
why would we be talking about that? :)
14:37
this is the firefox configuration support forum, no?
14:37
<Gadi>
oh, I just thought it was LTSP thats " impossible to find good documentation, since it's highly version-dependent."
14:37
;)
14:38
<vagrantc>

Lamebrowser Technical Support People?
14:41
(not that firefox is lame, just for mgariepy's clarification)
14:41
(only way I could think of to make it start with an L)
14:42
<vagrantc>
Lamentable
14:43
<highvoltage>
rofl
14:46
<mgariepy>
highvoltage, is not really rolling on the floor, for everyone's clarification :P
14:48
<robehend1>
I prefer to think of him actually doing that
14:49* highvoltage is so busted
14:55
<alkisg>
vagrantc: hmmm strange. The user was able to change his home page. It was saved in prefs.js. No user.js was created. Yet on the second firefox run, the "/etc/firefox/defaults/user.js" setting overrode the local prefs.js setting, which means that it was sourced afterwards... so yup that's not a good place for defaults, only for mandatory settings.
14:55
<vagrantc>
alkisg: that's weird. it definitely copied it into place for me.
14:56
/etc/firefox/defaults/prefs.js is the only one that worked the way i wanted it ... but any change in that on upgrades will be a problem.
14:59
<mgariepy>
any of you uses ibus + localapps here ?
15:06
<Gadi>
isn't ibus how Steve Jobs' kids get to school? ;)
15:07
<mgariepy>
hehe
15:07
<stgraber>
;)
15:07
<mgariepy>
anyone tried to port ltsp to mac ?
15:07
<stgraber>
mgariepy: we tried it with highvoltage two days ago
15:08
<Kyle__>
mgariepy: didn't port, but I did integrate some macs to my ltsp-labs via NIS & NFS.
15:08
<stgraber>
mgariepy: was too easy, so then we tested the new LDM RDP support connecting to win2008, then from there we started NX, then connected to another NX server from this NX session, then to an RDP server from there, to then connect to NX again and finally connect to the initial application server over NX
15:09
mgariepy: it was a bit confusing but fun ;)
15:09
<robehend1>
stgraber: I love NX so much. it's compression is fantastic.
15:09
<highvoltage>
yeah that nearly made my head explode
15:10
<Kyle__>
NX is one of those vnc alternatives, yes?
15:11
<robehend1>
Kyle__: mhmm, but much more efficent compression
15:11
Kyle__: I'm able to remote in and watch a youtube video, kind of thing
15:11
<Gadi>
there's a happy packet dance that you need to watch to understand it fully
15:11
<Kyle__>
robehend1: better than which compression? VNC can use any one of I think 8.
15:12
Gadi: happy packet dance.
15:12
<robehend1>
Kyle__: Not sure exactly. I've just never had any VNC i've used come close to VNC
15:12
<Kyle__>
OK just for that name alone, I want to watch.
15:12
<robehend1>
Kyle__: er, vnc come close to NX
15:12
Kyle__: Plus, it natively tunnels through SSH, always a bonus
15:13
<Gadi>
Kyle__: you can prolly find it on youtube
15:13
:)
15:13
<Kyle__>
robehend1: OK that _is_ a big plus.
15:14
<robehend1>
Kyle__: it also has a java web-client available, which runs cross platform, allowing remote access with 0 client configuration
15:14
<Kyle__>
That part just puts it at parrallel to VNC though (still massivelyi better than window's RDP)
15:16
<robehend1>
Agreed. I just like it. My students go nuts over it
15:17
<Gadi>
robehend1: are you using freenx, neatx, or the commercial one?
15:17
<robehend1>
Gadi: Freenx on the server, with the Nomachine clients
15:17
Gadi: Never had luck on neatx, not mature enough last time I checked, though showing promise
