12:26 | Runs very fast on a gigabit network.
| |
12:31 | <markit> so probably your vga is too old to support composition

12:31 | in any case, it makes things go much slower, I disable it by default

18:18 | <markit> hi alkisg, do you have some time to help me troubleshooting this terribly slow fat?
| |
18:18 | <alkisg> Hi markit, client specs?
| |
18:18 | <markit> well, is a 2GB, 2Ghz, dual core laptop
| |
18:18 | is just for test
| |
18:18 | <alkisg> OK, gigabit local network or 100mbps?
| |
18:18 | <markit> the server is a virtual machine on a i7
| |
18:19 | server gb, switch gb, laptop 100
| |
18:19 | <alkisg> So 100
| |
18:19 | <markit> but let me explain
| |
18:19 | it seems to go very fine until I login
| |
18:19 | then KDE is slow like hell
| |
18:19 | <alkisg> And are you using sshfs or NFS?
| |
18:19 | <markit> and if then open LibreOffice is fast
| |
18:19 | if I run dolphin, hopening home is slow like hell
| |
18:19 | I've started with sshfs and then tried to use nfs
| |
18:20 | thinking was a issue that would have been fixed
| |
18:20 | I've no idea if is really using nfs or not
| |
18:20 | <alkisg> On the client, run mount | grep home
| |
18:20 | <markit> in any case, nothing changed, it takes 3 minutes to be "usable"
| |
18:20 | ok
| |
18:21 | home type nfs
| |
18:21 | btw, fat client installation is US, don't know why did not took the server (italian) settings, is it normal?
| |
18:22 | <alkisg> Which ubuntu version?
| |
18:23 | If the server has italian settings in its /etc/default/locale, then yes the chroot should also default to italian
| |
18:24 | Did you have any other fat client installations with KDE, where KDE was fast? Or is it a general problem with KDE on NFS/SSHFS /home?
| |
18:24 | <markit> first time I try fat setup
| |
18:24 | kubuntu 11.04
| |
18:25 | (natty)
| |
18:25 | <alkisg> Try cat /opt/ltsp/fat-i386/etc/default/locale
| |
18:25 | And compare that to your server's
| |
18:25 | <markit> they are the same except ""
| |
18:26 | server: LANG="it_IT.UTF-8" chroot LANG=it_IT.UTF-8
| |
18:26 | maybe language packages are missing?
| |
18:26 | I've tired with a netbook as fat client, but same result
| |
18:27 | <alkisg> markit: try with LDM_LANGUAGE=it_IT.UTF-8
| |
18:27 | in your lts.conf
| |
18:29 | <markit> ok, I reboot the client, but will take 4 minutes
| |
18:29 | <alkisg> (08:19:32 μμ) markit: and if then open LibreOffice is fast ==> does openoffice, firefox etc *start* fast? I'm asking about the first time you launch them, does it take e.g. 20 seconds or 5 seconds?
| |
18:30 | (08:29:46 μμ) markit: ok, I reboot the client, but will take 4 minutes => Woww.... how much does it take to reach the LDM login screen?
| |
18:30 | Mine need about 13 seconds
| |
18:30 | <markit> to reach ldm login, takes 13 seconds
| |
18:30 | to logoff 1 minute
| |
18:31 | and to login in kde and see if is language ok, 3 minutes
| |
18:31 | kdm settings are "language italian, available languages US"
| |
18:31 | so I think that is set ok, but lacking all the i18n packages
| |
18:31 | I'll have a look in chroot
| |
18:31 | <alkisg> KDM? You're not using KDM for the clients, right?
| |
18:32 | After you login, just open a konsole and run `echo $LANG`,
| |
18:32 | <markit> sorry KDE
| |
18:32 | yes, KDM
| |
18:32 | <alkisg> and if it's wrong, put it to italian and launch kate from there
| |
18:32 | For fat clients you should be using LDM, the LTSP display manager
| |
18:33 | <markit> yep, I use LDM
| |
18:33 | it has the "ubuntu logo"
| |
18:33 | at least, I think this is what you mean, I login with the same stuff it shows with thin clients
| |
18:34 | <alkisg> Yes
| |
18:34 | By the way, if you set LTSP_FATCLIENT=False in lts.conf, so that you're using thin clients, do they run fast?
| |
18:35 | <markit> chroot has NO l10n italian package
| |
18:35 | yep, as thin it runs fast
| |
18:39 | <alkisg> markit: also check that your dns server/settings are correct
| |
18:39 | <markit> let me install missing packages and rebuild the image
| |
18:39 | define "correct" :)
| |
18:39 | I can dig from server
| |
18:39 | <alkisg> From fat clients?
| |
18:39 | <markit> also client is able to navigate
| |
18:39 | <alkisg> And reverse lookups?
| |
18:39 | <markit> let me try again
| |
18:41 | dig -x 192.168.20.108 returns ltsp108
| |
18:41 | the only thing that is not "perfect" is that server has hostname, not FQDN
| |
18:41 | I mean, hostname -f returns "gnuserver" only
| |
18:42 | <alkisg> It sounds ok...
| |
18:42 | <markit> I've not added a specific entry in /etc/hosts with FQDN (maybe one day you will clarify me all this stuff)
| |
18:42 | <alkisg> I would try this:
| |
18:42 | When at ldm, login to screen_02=shell
| |
18:42 | So that you get a root shell on the client while not user is logged in
| |
18:42 | Then, I'd do something like:
| |
18:43 | <markit> mmm rekonq navigation (is a browser) seems not that fast, to be sincere
| |
18:43 | <alkisg> mkdir /localhome
| |
18:43 | rsync -a /home/username /localhome/
| |
18:43 | (i.e. copy the user dir locally)
| |
18:43 | umount /home
| |
18:43 | rmdir /home
| |
18:43 | mv /localhome /home
| |
18:43 | This way you get a user home in tmpfs
| |
18:44 | So no nfs/sshfs is involved
| |
18:44 | If KDE runs fast this way, then those are to blame
| |
18:44 | (or KDE)
| |
18:44 | <markit> ok, to use shell do I have to add some line in lts.conf, or I recall wrongly? I've TONS of notes, but hard do recover
| |
18:45 | <alkisg> !screen_02
| |
18:45 | <ltsp`> alkisg: screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
| |
18:46 | <markit> let me ltsp-update-image so I will have italian keyboard, I think
| |
18:47 | (I've installed missing lang packages)
| |
18:47 | if KDE and fat don't work, I'm really in troubles :(
| |
18:52 | I've some herrors in rsyic, like "puse, permission denied"
| |
18:52 | or "some files/attr were not transferred" at the end
| |
18:54 | btw, in /home I've a hidden link .directory -> /etc/kubuntu-default-settings/direcotry-home
| |
18:56 | mm can't log in kde, a xterm message "kstartconfig4 does not exists or fails" error appears
| |
19:06 | is it normal that nfsiostat reports only headers, but no traffic data
| |
19:06 | ?
| |
19:06 | I mean, "Filesystem: rkB_nor/s wkB_nor/s rkB_dir/s wkB_dir/s rkB_svr/s wkB_svr/s ops/s rops/s wops/s" and then an empty line and then the prompt

20:16 | <alkisg> markit: did you try without NFS, as I said above?
| |
20:16 | WIth SCREEN_02=shell and all the rest?
| |
20:17 | <markit> mmm maybe I misunderstood
| |
20:17 | my first installation was without NFS, and I had the problem
| |
20:17 | then I activated NFS, and same problem
| |
20:17 | <alkisg> So you tried with sshfs and nfs,
| |
20:17 | <markit> then, with NFS, I tried to copy /home as you suggested
| |
20:17 | <alkisg> but you didn't try with a local home, which is what I'm suggesting
| |
20:17 | Ah, you tried taht?
| |
20:17 | <markit> but was not able to login in KDE due to other errors (see above)
| |
20:18 | [19:52] <markit> I've some herrors in rsyic, like "puse, permission denied"
| |
20:18 | <alkisg> You got this one? (08:56:04 μμ) markit: mm can't log in kde, a xterm message "kstartconfig4 does not exists or fails" error appears
| |
20:18 | <markit> and subsequent
| |
20:18 | yes
| |
20:18 | <alkisg> Did you manage to copy /home/username correctly?
| |
20:18 | What did you use, rsync and NFS?
| |
20:19 | khildin has left IRC (khildin!~khildin@ip-83-134-232-39.dsl.scarlet.be, Quit: I'm gone, bye bye) | |
20:20 | <markit> yes, was with nfs setup, rsync failed in copying some files
| |
20:20 | <alkisg> Or, just create a new /home/username, empty, but take care for it to have correct permissions
| |
20:20 | <markit> also rmdir did not worked, due to a link
| |
20:20 | <alkisg> If you have epoptes installed, I can help you remotely if you want
| |
20:21 | <markit> I would love! I've not it already installed, but following the wiki is not hard ;P
| |
20:21 | just please wait some minutes I've to copy some important data from my father's Win200 PC he uses for some CAD
| |
20:21 | <alkisg> OK, it will help in getting remote access to screen_02=shell etc
| |
20:21 | <markit> he had an error and was unable to boot
| |
20:21 | <alkisg> Sure, I have to do something before as well
| |
20:22 | <markit> now I've booted and I'm in hurry in save the hd content
| |
20:22 | (unfortunatly, closed source very expensive hardware protected CAD involved, sigh
| |
20:22 | )
| |
20:22 | <alkisg> VMs are handy there :)
