[16:59] <alkisg> stilyan: switch to ltsp fat clients?
06:39
why Should I ?
06:39
<alkisg>
stilyan: I pasted the link where I document it, in the wiki
06:39
<stilyan>
it worked very well with i386 image
06:39
<alkisg>
Read it? :)
06:39
<stilyan>
not asking for documentation, asking Why
06:39
<alkisg>
I documented "why"
06:40
"performing amazingly better" etc
06:40
<stilyan>
sorry but as I said .. dual monitor setup used to work well with i386 thin client in the past
06:40
so I seriously doubt its resources
06:41
any other suggestions besides switching to fat ?
06:41
<alkisg>
stilyan: what are you client specs, i.e. cpu and ram?
06:41
<stilyan>
no less than dual core CPUs and 2gb ram
06:42
<alkisg>
You can't expect to be able to send 4gbps per client, for dual monitor updates, performance will suffer
06:42
<stilyan>
network is gigabit
06:42
<alkisg>
At some point xdamage and non compositing managers were able to send only the screen diff, the updates
06:42
Now with compositing and videos and scrolling etc, they frequently need to send the whole screen
06:43
That's xorg/window manager changes, not related to ltsp
06:43
<stilyan>
well damn :)
06:43
<alkisg>
If at some point the server needs to send 30fps of 2 monitors of 1920x1080, that's 4gpbs for a single client
06:43
so for 10 clients, you'd need 40 gbps networking, impossible
06:43
...hence, we deprecate thin clients in ltsp and recommend fat clients
06:44
And now I just typed the documentation i wrote yet again :)
06:45
Your clients are very suitable for fat clients, they'll run much better that way
06:45
So I'd recommend that you do a test (or real) installation using the most up to date tutorial:
06:45
!install
06:45
<ltsp>
install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
06:46
<stilyan>
ok, thanks
06:46
<alkisg>

<stilyan>
[08:43] <alkisg> That's xorg/window manager changes, not related to ltsp
06:55
when was this introduced, do you know ?
06:56
<alkisg>
stilyan: it's not a single change, it's dozens of changes that started years ago
06:56
xorg as a network protocol hasn't been maintained properly even before I joined ltsp
06:57
<stilyan>
understood
06:57
<alkisg>
stilyan: When you're done with the change, you'll say to yourself "hey this goes much faster, why didn't I do this 5 years ago?"
06:57
So don't worry too much about thin clients, just go with the flow
06:57
<stilyan>
ok, i'll surely try
06:57
thanks again

<stilyan>
what are the 'supported' fat desktops? is this still relevant? # ubuntu-desktop and edubuntu-desktop are tested.
07:12
i was thinking lubuntu
07:12
<alkisg>
Read this please:
07:12
!install
07:12
<ltsp>
install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
07:13
<alkisg>
I even have the link to the iso there
07:13
Not just the recommended flavor :)
07:13
It's also much easier if you use the "chrootless" setup mentioned there
07:14
So, you'd install mate or even lubuntu on your server directly, and then just run the ltsp-update-image -c / command, without ever using ltsp-build-client
07:14
<stilyan>
thanks

<stilyan>
ltsp.org not opening for me today
07:15
<alkisg>
Let me see...
07:16
stilyan: ok, i restarted apache, try again
07:16
Hopefully jammcq will at some point upgrade that from 8.04 to something newer :D
07:16
stilyan: if you only read one page of documentation, read that one
07:17
And I suggest that you try the "chrootless" variant, not the old style "chroot" one

<stilyan>
--fat-client run most or all applications locally --fat-client-desktop run most or all applications locally
12:18
what's the difference ?
12:26
nvm, found in ubuntu doc

stilyan: try without ltsp-build-client first, the chrootless method, where you don't need --fat-client nor --fat-client-desktop etc
