hi guys, if I have an ltsp x64 server with i386 image
11:06
and i want to use the nvidia driver for
11:06
dual screen
11:06
which driver i have to laod?
11:06
x86 or 64?
11:09
<chrisjrob>
Guest3931: the driver is installed on the client, so go with what's running on the client
11:09
i.e. i386
11:10
<Guest3931>
ok, But now well I download the driver from nvidia?
11:11
with iceweasel for debian
11:11
and then i must install it running from the client?

<chrisjrob>
Guest3931: you have to log into the chroot rather than the client
11:15
preferably using ltsp-chroot command
11:15
alternative using: sudo chroot /opt/ltsp/i386
11:15
!ltsp-chroot
11:15
<ltsp>
chrisjrob: ltsp-chroot: you can download ltsp-chroot from http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/view/head:/server/scripts/debian/ltsp-chroot
11:16
<chrisjrob>
ltsp-chroot just does the chroot but mounts and unmounts proc and sys for you

Guest3931: these are the instructions for Ubuntu LTSP Atom ION, which will give you an idea at least https://help.ubuntu.com/community/UbuntuLTSP/AtomIon
11:17
does depend what you're running though
11:18
<Guest3931>
thanks I`ll check

I'm managing nbd-server via pacemaker and it nicely hops from server to another when needed. But how I re-establish connection from client after that failover?
13:01leio_ is now known as leio
13:03
<Yoe>
muppis: you can't move your nbd-client connection to another server ATM. It just doesn't support that
13:04
muppis: I guess in theory it would be possible with the -persist thing, but that isn't implemented
13:04
patches are welcome, I guess :-)
13:04
<muppis>
Yoe, not even moving servers IP as well?=
13:04
-=
13:04
<Yoe>
if not, I might look into it some time into the future, but I can't say when
13:04
muppis: well, if you can live with a few lost writes, then I guess you can run nbd-client in a loop and have it connect to a DNS name
13:05
muppis: once nbd-client disconnects from the device node, the kernel will start issueing EIO errors
13:05
at least that's the idea -- not sure whether Paul ever submitted that patch to Linus
13:06
so if you don't want lost writes, you need to have nbd-client reconnect immediately
13:07
currently it does that by trying to open a new connection to the exact same server; it doesn't do anything more, on the idea that that probably won't work (which is probably true if your root device is on nbd)
13:09
<muppis>
Losing writes is not the problem. Just need to get reconnected.

I think xnbd supports multiple servers, I've never tried it though...
13:11
<Yoe>
alkisg: yeah, right, it does
13:11
<alkisg>
So maybe it call fallover without you doing anything

13:12
<alkisg>
Yoe, did those people try sending patches upstream? Or they just forked nbd without even trying to send patches?
13:16
<Yoe>
alkisg: the latter
13:16
<alkisg>
Meh
13:16
<Yoe>
alkisg: I contacted them to talk about possibly cooperating so that our protocols wouldn't be incompatible, and they didn't even want to do that
13:16
I just threw up my hands in disgust after that
13:16
<alkisg>
Yeah, totally understandable
13:17
Guest3931: I think the debian documentation for installing nvidia binary drivers is there: http://wiki.debian.org/NvidiaGraphicsDrivers#Installation-1

<mgariepy>
hey alkisg
15:53
<alkisg>
Hi mgariepy, what's up?
15:53
<mgariepy>
not much, i found what is wrong with ltsp-genmenu !
15:54
why it takes a lot of time when using fat client (or a lot of local apps ) :)
15:54
<alkisg>
Er... that's what we use with localapps, right?
15:54
<mgariepy>
yeah
15:54* alkisg doesn't use localapps in any of his setups...
15:54
<alkisg>
What's wrong with it?
15:55
<mgariepy>
it uses find when looking for icons, once per icon and it take about 1.5 sec per call.
15:55
<alkisg>
once per icon? ouch
15:55
<mgariepy>
lol yeah
15:56
and the regex wasn't good for the find command, we were lucky that it was working :)
15:57
i fixed the regex and i will fix the rest this week probably to find all the icons in one shot.
15:57
therefore calling find only once.
15:59
<alkisg>
mgariepy: are you planning to cache all .png, .svg etc files for the next loop? Or are you going to find all the icons with a single find command?
16:01
<mgariepy>
find all icons in a single call
16:03
it will add a few milliseconds to the call per items but it will be much better then right now.
16:03
<alkisg>
Yeah multiple finds == very bad performance
16:04
<mgariepy>
indeed.
16:04
<alkisg>
I wonder if we could use some system function to locate the icons though
16:05
<mgariepy>
when having only 1 or 2 localapps, it's not too bad only adding 2-3 sec to login time but when having 10 localapps, it take like 15sec only to generate this menu

Hello. I have just come into a company using LTSP 4.2 and trying to get farmiliar with it. They have a user, when logged on, gets a flashing cursor and taskbar and the desktop icons take a long time to load. Also, nothing on the taskbar can be clicked on.
21:09
Is there somewhere I can go to reset the settings just for his sessions/
21:10
<muppis>
Wipe everything from users home dir.
21:11
<vagrantc>
or just create a new user, and move all the user's documents/files/etc. into the new user's homedir.
21:11
(and change permissions and such)
21:13
<muppis>
Easier to take backup and let system recreate needed files and then restore documents.
21:14
I've done that way. No need to hazzle with permissions.

Ok, Ive moved his home folder out. How do I create a new one with the appropriate files and permissions and such?
21:17
<muppis>
Just create dir for that user and set same permissions and owner/group as old one. After that done, login with that user.
21:23

Thanks, that seems to have worked.
