| 06:39 | <stilyan> [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> np

| 06:55 | <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

| 07:12 | <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
| |
| 07:14 | <alkisg> np
| |
| 07:15 | <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

| |
| 12:18 | what's the difference ?
| |
| 12:26 | nvm, found in ubuntu doc
