<jokoarie>
anyone can tell me how to debug thin client boot process in edubuntu 11.10, cause i have 1 stuck pc within boot process
09:42
<muppis>
Remove words quiet and splash from /var/lib/tftpboot/ltsp/<arch>/pxelinux.cfg/default and reboot client
09:44
<jokoarie>
2 thumbs for muppis, great, i will try it your suggestions, thx alot guys!
09:46
<muppis>
No problem.
09:49
<jokoarie>
hey muppiss, can you give me quick hints to this problem, i made successfulll client boot whne i try with my laptop as client, but with 1 of my pc it stuck boot process when its show dotted progress , and words "done!" came up with nothing else show up
09:50alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg)
09:51
<muppis>
jokoarie, haven't faced that before. Maybe alkisg can give you a hint for that.
09:51
<alkisg>
Good morning
09:51
<muppis>
alkisg, morning. :)
09:51
<jokoarie>
morning alkisg
09:52
<alkisg>
Is that PC an old one?
09:52
<jokoarie>
alkisg ...., can you give me quick hints to this problem, i made successfulll client boot whne i try with my laptop as client, but with 1 of my pc it stuck boot process when its show dotted progress , and words "done!" came up with nothing else show up
09:52
yes
09:53
<alkisg>
The new ubuntu kernels require some instructions not available in very old hardware, like the cmov instruction
09:53
How old is it?
09:53
<jokoarie>
very old, pentium II
09:53
:D
09:53
<alkisg>
And how much RAM?
09:53F-GT has joined IRC (F-GT!~phantom@ppp121-44-144-117.lns20.syd7.internode.on.net)
09:54
<jokoarie>
256mb
09:54
<alkisg>
That's more than enough... so it may be a problem with the processor
09:55
Can you try booting that client with the 11.10 live cd?
09:55
<jokoarie>
i just upgrading server ltsp from redhat 9 to edubuntu 11.10
09:56
<alkisg>
If the problem is the old processor, you may probably use edubuntu 10.04
09:56
<jokoarie>
with redhat 9 its can boot, but the server now is dead, i buy iyt new pc for the server
09:56
<alkisg>
That's an LTS (Long Term Support) release, so it's even supported for more than 11.10
09:57
<jokoarie>
how minimum ram should client have ?
09:57
<alkisg>
64 with some configuration changes, 128 out of the box
10:00
<jokoarie>
can i debug where is the error in booting process, mupiss suggest me to Remove words quiet and splash from /var/lib/tftpboot/ltsp/<arch>/pxelinux.cfg/default and reboot client

<wizzy>
folks - we have old external network cards with boot roms on them - can I make these boot just like PXE ?
11:24
most of the lab has PXE - but a few old clunkers have no PXE - and there is no PROM programmer in sight
11:25
<highvoltage>
wizzy: I speak under correction, but I think if will work if you install the mknbi package and then run ltsp-update-kernels
11:25
<wizzy>
there is a conditional in dhcpd.conf to select the non-pxe cards - which it points to nbi.img, but that seems not to work
11:26
highvoltage: thx - trying that now
11:30
mknbi was not installed - I installed it - ran ltsp-update-kernels - but no files in /var/lib/tftpboot/ltsp/i386/ changed
11:31
will try running mknbi-linux per man page
11:38
hmm - "segment in reserved area" messages this time

15:42
<manni>
HI
15:44
I have trouble with my ltsp client; after some time i get black menu,s and what ever I open new is only completly black!
15:44
like if some buffer of x is running full
15:44
nbdswap is enabled
15:44
also x compression is on in lts.conf
15:50
<alkisg>
manni, how much RAM does your client have?
15:50
<manni>
something like 512mb
15:50
<alkisg>
!compiz
15:50
<ltsp`>
alkisg: compiz: the default window manager in gnome is gnome-wm, which automatically chooses compiz if it thinks that the card supports it. Compiz is causing login problems to some clients (LP #673072). To disable it, see !disable_compiz. To restore it, see !restore_compiz
15:50
<alkisg>
Try disabling compiz
15:51
Also, what do you mean with "x compression is on"?
15:51
Do you mean LDM_DIRECTX=False, which is the default?
15:51
<manni>
yes ldm direct x true
15:51
i have on the cards nvidia prop driver installed
15:52
you showed me some days ago howto do! :)
15:52
<alkisg>
Try the command for disabling compiz
15:52
<manni>
probably thats it
15:53
<alkisg>
muppis: the problem is that you're using IPAPPEND 3, so need to symlink ltsp/i386 to ltsp/amd64
15:53
wizzy: if you remove the conditional in dhcpd.conf, and always send "filename=pxelinux.0", does it work for those clients?
15:54
<manni>
he sorry i dont find this disable compiz you mean in shell?
15:56
<alkisg>
manni: read the help text, it says "To disable it, see !disable_compiz. To restore it, see !restore_compiz"
15:56
So you need to type HERE in IRC: !disable_compiz
15:56
Type it
15:58
<manni>
!diable_compiz
15:58
<ltsp`>
manni: I do not know about 'diable_compiz', but I do know about these similar topics: 'disable-compiz'
15:59
<manni>
disable_compiz
15:59
!disable-compiz
15:59
<ltsp`>
manni: disable-compiz: To disable compiz for all users, run: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity
16:02
<manni>
ok
16:02
thanks I`ll see now
16:08
@alksig do you have any tweaking tips
16:09
I have running clients in dual screen setup but I have to say running firefox with youtube vids brings my terminal to his end
16:15
<alkisg>
manni: if you use <tab> to autocomplete the names, you'll get them right :)
16:15
!flash
16:15
<ltsp`>
alkisg: flash: Yes, flash sucks. Make sure you have LDM_DIRECTX=True in your lts.conf file, or if it's just youtube you're after, try some flash replacing plugin like https://addons.mozilla.org/el/firefox/addon/161869/ (per user installation, gecko-mediaplayer is also needed).
16:16
<manni>
I CAN CONFIRM FLASH REALY SUCKS ! >:o
16:17
he alksig are you greek?
16:24
<wizzy>
alkisg: I did not try that, no. why would the conditional be there if it worked for both ?
16:25
<alkisg>
manni: yes, I'm Greek, and my username is "alkisg", not "alksig", please use the "tab" in your keyboard to have it autocompleted
16:25
wizzy: some older clients only work with nbi
16:25
But most new etherboot clients also work with pxelinux
16:25
And since nbi is broken since 9.10, you may try forcing pxelinux.0, to see if it works for you
16:26
<manni>
alkisg:
16:26
<wizzy>
alkisg: worth a try - thanks. "etherboot clients" - is that my rom-o-matic ROM ?
16:26
<manni>
yes!
16:26
<alkisg>
wizzy: rom-o-matic is etherboot, yes, and that project then evolved to "gpxe", which is pxe compliant
16:26
!gpxe
16:26
<ltsp`>
alkisg: gpxe: the successor to etherboot (http://etherboot.org). To download bootable floppy, cd, usb, kernel etc images, visit http://rom-o-matic.net/
16:27
<wizzy>
The rom is rom-o-matic vintage
16:27
<alkisg>
wizzy: so if you download a gpxe rom from there, it will work out of the box
16:27
(or floppy, or cd, etc)
16:27
<wizzy>
alkisg: I understand - but then I need a programmer - which I had once
16:28
<alkisg>
wizzy: or just to remove the conditional :)
16:28
<wizzy>
alkisg: I will try that, thanks

<knipwim>
vagrantc: perhaps time for version tagging ltsp-trunk soon?
21:18
<vagrantc>
knipwim: i've been pondering it
21:18
knipwim: there are significant enough changes to consider 5.3.0
21:19
<knipwim>
i guess
21:20
<vagrantc>
the switch to initramfs stuff, anyways.
21:20* vagrantc wanted to fix up the initramfs stuff to be easier to backport before tagging, but whatever
21:21
<knipwim>
you could do a 5.2.99
21:22
i was only concerned for the gentoo ltsp-server stuff
21:22
<vagrantc>
or just keep bumping it ... most of the changes are optional, i think.
21:24
<knipwim>
and leave the 5.3 until the initramfs stuff is complete?
21:24
<vagrantc>
maybe ... hasn't been much activity since the BTS, other than certain gentoo developers :)
21:25
<knipwim>
i was discussing some plugin changes with alkisg earlier
21:25
going for function based plugins rather than file based ones
21:28
<vagrantc>
yes, i recall that
21:29
<knipwim>
got a working example now
