With all other computers, ltsp works fine. But I have one computer that as soon as it starts X, the screen goes black and nothing happens. Can anyone help?

Good morning
02:30cyberorg has quit IRC
02:35
<sweetpi>
Is there any way to stop X from starting in lts.conf?
02:35
screen_07=shell doesnt seem to effect it
02:36cyberorg has joined #ltsp
02:39
<alkisg>
sweetpi: can you paste your current lts.conf?
02:39
!pastebot

02:40
<sweetpi>
its the default, all I added was SCREEN_07=shell
02:41
it also shows up in the tftp logs
02:43
<alkisg>
There's no default lts.conf
02:43
Which distro/version is that?
02:44
<sweetpi>
sorry, i tried it in the default lts.conf, and then i added on in tftp. its debian
02:44
squeeze
02:44
<alkisg>
Does debian get lts.conf with tftp? I thought it uses nfs...
02:45
<sweetpi>
im using nbd
02:45
yes it shows up in the tftp logs, but ive also tried in the clients lts.conf
02:46
my config: http://pastebin.com/HtDYmije

<elias_a>
Now that I recall - has someone solved how it would be possible to play audio cds in clients using the cdrom drive of the client?
02:47
People ask me this on continuous basis and I have not been able to find an answer.
02:47
<alkisg>
sweetpi: do you have sid backports enabled?
02:47
<sweetpi>
alkisg: the only reason im trying this is the screen goes black after X starts
02:47
alkisg: no
02:47
<alkisg>
OK, I think the only way to debug it then is to enable the chroot root account
02:47
Something like that: https://help.ubuntu.com/community/UbuntuLTSP/UnlockChrootRootAcct
02:48
<sweetpi>
alkisg: I cant switch terminals after it black screens
02:48
<alkisg>
Hmmm
02:48
<elias_a>
sweetpi: Do you already know that you should not use Compiz in LTSP?
02:48
<alkisg>
It doesn't reach ldm, does it?
02:48
<sweetpi>
elias_a: I havent changed anything from default
02:48
alkisg: the last thing i see is the drm module loading
02:49
<elias_a>
sweetpi: If it is a new installation, it is possible the graphics chip is not compatible with Compiz or some other part in X configuration.
02:50
<alkisg>
elias_a: that's after the user logs in, though
02:50
He should be seeing the login screen if it was a compiz problem
02:50cyberorg has quit IRC
02:50
<alkisg>
sweetpi: try putting XSERVER=vesa in lts.conf
02:50
<sweetpi>
ive tried that
02:50
<elias_a>
alkisg: Ok.
02:50
<alkisg>
...even though I doubt that your lts.conf is being read
02:51
<sweetpi>
alkisg: im not sure if its being read, but its getting downloaded via tftp
02:51cyberorg has joined #ltsp
02:52
<sweetpi>
ive tried vesa and vga, ive even tried changing resolutions
02:53
I should mention this is a laptop
02:53cyberorg has joined #ltsp
02:55
<elias_a>
sweetpi: Is it compatible with linux? I mean, should the graphics work out of box?
02:55
<alkisg>
do other clients boot?
02:57
<sweetpi>
elias_a: yes, it has a local install of maybe 8.0ish ubuntu
02:57
alkisg: yes the others work fine
02:57
<alkisg>
sweetpi: ok, then run `getltscfg -a` on the others to see if they receive lts.conf
02:58
<sweetpi>
ok
03:00
<alkisg>
(on a local terminal - either on SCREEN_02=shell or with a root account on vt1)
03:01
<sweetpi>
alkisg: i would say its getting the config, it dropped to a shell :)
03:01
<alkisg>
ok
03:02
<sweetpi>
i had screen_07=shell in the tftp lts.conf
03:04
i checked the local os xorg.conf and its empty, so there isnt anything custom going on
03:05
<alkisg>
sweetpi: so... if your other clients don't load X when you put screen_07=shell, and this one hangs, then it isn't an X problem, right?
03:06
<sweetpi>
a video driver problem is my guess
03:06
but it works fine on the local os
03:07
<alkisg>
But without trying to load X?
03:07
Why would a video driver be a problem if it doesn't try to load X?
03:07
<sweetpi>
i see drm getting loaded, would that get loaded even without X starting up?
03:08
<alkisg>
I'm not familiar with the debian boot messages, but if screen_07=shell is working on other clients, it should be working on that one too.
03:08
<sweetpi>
the drm=Direct Rendering Manager or somthing like that
03:09
i agree... so confused
03:09
<alkisg>
Is that after "starting ltsp client"?
03:10
<sweetpi>
yes i think, i only tried to look at the last message
03:11
it gets past mounting the image, then starts udev, etc... let me see what else i can catch
03:13
i didnt specifically see "starting ltsp client" but its hard to read much with udev messages flying around
03:14
<alkisg>
sweetpi: hmmm I'd suggest you'd come back in this channel about 10 hours later, and see if vagrantc (=the debian ltsp maintainer) can help you
03:15
<sweetpi>
ok

sweetpi: Nice. Wow, I wouldn't think of that.
03:54
<sweetpi>
alkisg: thanks for your help. pointing out that X _really_ shouldnt be loading made me look for other problems :)
03:54
<alkisg>
You're welcome - but you deserve all the credit yourself
03:59
<sweetpi>
wow this really brought a junky computer to life... 128mb ram.. and over wireless too(maybe i should write a tutorial on that part)
04:00
open office used to take 4-5min to start now its down to about 5 seconds :)

anyone know if there is an lts.conf option to allow specific machines to be shutdown by the client? I seem to remember seeing it, but cant seem to locate it in the docs.
04:27phil_ has joined #ltsp

<phil_>
hello, I'm looking for help to compile LTSP 5.2 on Ubuntu
04:28
I have the .tar.gz, I have executed ./authgen.sh but there is no "configure" file so now what do I do ?
04:28
./autogen.sh I meant
04:29
<alkisg>
phil_: why would you want to compile it?
04:29
One quick way to do it is: apt-get source ltsp; apt-get build-dep ltsp; debuild -b -tc
04:29
<phil_>
I have a hardy server (with ltsp-server 5.0) and it seems I can't install a lucid distrib with the 5.0 version
04:30
so I wanted to try and compile the 5.2
04:30
(there is no backport for hardy)
04:30
<alkisg>
phil_: maybe you should explain your problem better, because I don't think compiling will help you
04:30
You want to put ltsp 5.2 on hardy?
04:30
<phil_>
yes
04:30
<alkisg>
It requires upstart and other stuff not found in hardy
04:30
Why would you want ltsp 5.2?
04:30
<phil_>
I first looked for a backport of 5.2 for hardy, but there is not
04:31
<alkisg>
Backporting ltsp 5.2 to hardy would involve some code rewritting
04:31
Why do you want ltsp 5.2?
04:32
<phil_>
my goal : I want ltsp clients which run on lucid ; and I was hoping I could install a lucid distrib on my hardy server (my servers are under hardy-server, the last LTS)
04:32
<alkisg>
I don't understand your statemend "lucid distrib on hardy server"
04:32
The last LTS is Lucid, not Hardy
04:33
Maybe you should be upgrading your server to Lucid?
04:33
<phil_>
so I installed (on my hardy server) the package ltsp-server (5.0 version) and tried : ltsp-build-client --dist lucid ; and I get an error
04:33
the last LTS for server version is hardy
04:34
"lucid distrib on hardy server" means I want a ltsp-server which allows ltsp clients tu run lucid
04:34
<alkisg>
phil_: http://www.ubuntu.com/server/get-ubuntu/download
04:34
The last LTS for server is Lucid, afaik
04:34
Where did you hear that it isn't?
04:34Da-Geek has joined #ltsp
04:36
<phil_>
well, I thought that for server edition, LTS was released every 3 years (instead of 2 years for desktop edition)
04:36
<alkisg>
No. You just get support for 5 years, instead of 3.
04:36
<Da-Geek>
Hi All, looking for anyone who deals with RPM'ing LTSP for Fedora, any pointers ?
04:36
<alkisg>
(again afaik - but I've never heard otherwise)
04:36
<phil_>
well.... ok then , I think I will install a lucid server, with ltsp-server 5.2 :-)
04:36
<alkisg>
That'd be the easiest way :)
04:37
<phil_>
for my information, would the 5.2 version of ltsp-server compile under hardy ? (if I install all dependencies requiered ?)
04:37
<alkisg>
Da-Geek: ltsp for fedora is currently unmaintained, afaik. Warren was the last maintainer but he hasn't shown up in months
04:37
<phil_>
and if yes, how do you compile it : ./autogen.sh will create some configure files, won't it ?
04:37
<alkisg>
phil_: no, without code changes it wouldn't install. It needs upstart, which isn't available on hardy
04:37
<Da-Geek>
alkisg, /me knows (/me works for Red Hat) was looking for anyone else who may have been involved...
04:38
<phil_>
ok, thanks
04:38
<alkisg>
phil_: you create a .deb with `debuild -b -tc`
04:38
<phil_>
ok
04:38
<alkisg>
Da-Geek: I don't think there's anyone else. I've been hearing people ask about fedora help here, and they always get the same answer (unmaintained)
04:39
Da-Geek: to get a more "official" answer you could try the ltsp mailing list..
04:39* Da-Geek is looking @ Taking over the Fedora RPMs (pos RHEL/CentOS as well)
04:39
<alkisg>
That'd be cool
04:40
Yeah, I think asking in the ltsp-developer mailing list would be best
04:40* Da-Geek is a long time user of K12LTSP before i worked @ Red Hat..
04:40
<alkisg>
https://lists.sourceforge.net/lists/listinfo/ltsp-developer
04:40
<Da-Geek>
would be a shame to lose LTSP from Fedora...
04:40
<alkisg>
Right... and I bet it doesn't need much to get it working again
04:41
<Da-Geek>
alkisg, i hope not....
04:41
i just wanted to check things out 1st before i go stepping on someones toes..
04:41
<alkisg>
Da-Geek: ltsp developers here are very helpful, even if you bump into some problems I'm sure we'd help.
04:42
I guess if you ask on the mailing list, warren will be the first one to give you his "blessing" :)
04:42
<sweetpi>
If I clean up my scripts to add wireless, where would be the best place to submit them?
04:42mordocai has joined #ltsp

sweetpi: well... debian does have a wiki, but most people look at the ubuntu one
04:42
So if those work for ubuntu too, please put them there as well
04:43
https://help.ubuntu.com/community/UbuntuLTSP/
04:43
The debian one is here, I think: http://wiki.debian.org/LTSP/Howto
04:43sean74 has joined #ltsp
04:44
<sweetpi>
I imagine they would work on anything, they just use built-in ltsp script functions. Actually quite simple.
04:45
<alkisg>
How do you boot the client? With a local nbd image?
04:45phil_ has left #ltsp
04:45
<sweetpi>
local kernel and initrd, everything else is normal
04:46
<alkisg>
Sounds good
04:46
<sean74>
any advice for fat/thin cliet local printer
04:47
<alkisg>
Fat or thin?
04:47
There's a difference there
04:53
<rickogden>
hey, I've just rebooted (working) LTSP server, now when I try to connect a client it says "nbd0:Hangup"
04:58Selveste1 has quit IRC
05:02
<sean74>
fat
05:03
is it necessary to input the MAC addr?
05:03
<sweetpi>
rickogden: maybe your inetd.conf has changed, or your nbdport kernel options?(just guessing)
05:03
<sean74>
can i configure the printer device for all client?
05:04
<rickogden>
sweetpi: I've just checked, and it seems to be the correct port
05:05
<alkisg>
sean74: if it's a fat client, it should automatically see any local printers
05:05
<sweetpi>
your sure the inetd.conf wasnt changed after you restarted inetd(before reboot)?
05:06
<rickogden>
I've checked /etc/inetd.conf and it's correct
05:06
<sean74>
hmmm
05:07
<sweetpi>
rickogden: what does syslog on the server say?
05:07
<sean74>
i think i need to clarify something here, 1st i install ltsp the ubuntu-server then i tasksel ubuntu-desktop
05:07
will it be the same?
05:10
<rickogden>
sweetpi: it says authorized client then "starting to serve" then "nbd_server[21018]: Size of exported file/device is 4096"
05:11
<sweetpi>
rickogden: bad symlink?
05:11
that file is way too small
05:11
<rickogden>
could be... what would the symlink that I'm looking for be?
05:11
<sweetpi>
using debian?
05:12
<rickogden>
ubuntu
05:12
so yeah
05:12
<alkisg>
rickogden: grep nbd /etc/inetd.conf
05:12
<sweetpi>
check your inetd.conf for the image file that is set to the nbdport
05:12
<alkisg>
See if you export the image there instead of the directory
05:12
<rickogden>
alkisg: I did that before, and it is
05:12
<sweetpi>
ls -al pathtofile
05:13
see if its a broken symlink or a directory
05:13
<alkisg>
rickogden: can you paste that? 4096 is usually an exported directory
05:13
sean74: if you created a fat chroot, it shouldn't matter what desktop you have on the server.
05:14
<rickogden>

05:14
<alkisg>
And, grep nbd /etc/inetd.conf ?

05:15
<alkisg>
And, grep nbd /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default ?
05:15
<rickogden>
alkisg: it's not being used
05:16
<alkisg>
(or grep vmlinuz)
05:17
<rickogden>
I'm using the same gpxe boot script which specifies the nbdserver as a parameter
05:17
<alkisg>
Ah
05:17
And you're passing nbdport=2002 ?
05:17
The default nbd port is 2000
05:18
<rickogden>
no, that didn't work, I'm passing nbdroot=ip:2002
05:18
<alkisg>
Hrm... yup now I remember...
05:18
<rickogden>
yeah...
05:19
<alkisg>
You get a busybox on the client?
05:19
<rickogden>
no
05:19
I'm trying to think as the file size it passes is the size of a symlink or directory file
05:20
what should it be passing at that point?
05:22
<sweetpi>
rickogden: did you try rebuilding the nbd image? i remember something like this from a corrupt image
05:22
<rickogden>
sweetpi: what's the command?
05:23
<sweetpi>
ltsp-update-image -a i386
05:23
<rickogden>
oh the ltsp image :)
05:25
<sean74>
hmmm
05:26
<rickogden>
same thing :/
05:26
<sean74>
alkisg: coz, when i go to the printing configuration i only see the server ip
05:27
alkisg: do you meant that if i run on fat, i dont even need to configure the lts.conf?
05:28
<alkisg>
rickogden: while you're at it, why don't you try to change your inetd.conf so that it uses the standard port? (2000)...
05:28
<rickogden>
kk, using the dpkg-reconfigure?
05:28
<alkisg>
No, manually should be easier
05:28
sudo gedit /etc/inetd.conf
05:28
and sudo invoke-rc.d openbsd-inetd restart
05:28
And change your gpxe script too..
05:28
(no need to specify the nbd port anymore)
05:29
<rickogden>
righto
05:29
<sean74>
alkisg: this is the command that i use to build the ltsp client, sudo ltsp-build-client --arch i386 --chroot fati386 --fat-client-desktop ubuntu-desktop --purge-chroot --mount-package-dir /var/cache/apt/archieves
05:31
<alkisg>
sean74: yes, for fat cilents, you don't need an lts.conf to access local printers
05:32
<sean74>
alkisg: hmmm, is there anything that i should reconfigure??
05:33
<alkisg>
I don't know. I don't know what your problem is. Fat clients don't see local printers? Or your clients don't boot as fat?
05:34
<sean74>
alkisg: how can i know if my client not boot as fat?
05:34
<rickogden>
alkisg: I had to alter the /etc/nbd-server/config file, but it's fixed the problem :/
05:35
<alkisg>
rickogden: weird. What did you put there?
05:35
You shouldn't have this file at the first place...
05:35
<rickogden>
just changed the port to 2000, then did an /etc/init.d/nbd-server restart
05:35
alkisg: could this be causing the problem?
05:35
a config conflict?
05:35
<alkisg>
Erm... why did that file exist?
05:35
On a default ubuntu installation, nbd-server runs from inetd
05:36
So it doesn't run as a server (nbd-server restart)
05:36
And it doesn't need a configuration file
05:36
So at some point you must have done something to create that file
05:36
<rickogden>
yeah, I think it was during the dpkg-reconfigure nbd-server
05:36
which I did when I couldn't get them talking in the first place
05:37
<alkisg>
Hm. Maybe you should revert to the ubuntu defaults then
05:37
<rickogden>
yeah, maybe a plan
05:37
<alkisg>
It'd be easier to get support some next time
05:37
So, delete that configuration file
05:37
Stop nbd-server
05:37
And restart inetd
05:37
Btw now you'll have a conflict if you leave both nbd-server and inetd at port 2000
05:37
Maybe that's what was causing the problem
05:38
<rickogden>
my thoughts exactly
05:38
<alkisg>
sean74: on the client, open a gnome-terminal and see the hostname there.
05:39
It'll be either your server hostname, which means it's a thin client, or the client hostname, which means it's a fat client.
05:39
<rickogden>
alkisg: that seems to work, I'll remove the nbd-server from init.d
05:41
<sweetpi>
that init script is default
05:42
<rickogden>
sweetpi: oh, so I should keep it?
05:42
<alkisg>
Yes, it just doesn't start if it doesn't find a configuration file
05:42
So yup, keep it
05:42
(whatever)
05:43
<rickogden>
ok, thanks people!

<rickogden>
I must say, I was rather impressed with the dual monitor support of LTSP
05:44alkisg has joined #ltsp
05:45
<sean74>
alkisg: if fat client what would i see?
05:45
<alkisg>
sean@ltsp123
05:45
<sean74>
is the hostname + the ip address
05:45
yup
05:45
something like that
05:46
username@hostname[ipno], sean@ltsp20
05:46
<alkisg>
So if you run e.g. `free`, you'll see your client's memory (e.g. 1 Gb), not your server's memory (e.g. 4 Gb)
05:47
<sean74>
ok, so i should see the local device memory size instead of server memory
05:47
if it shows server ram size?
05:47
<alkisg>
Then it's a thin client
05:48
<sean74>
ok, is that due to the hardware then? coz, i boot from a normal cpu
05:48
not the thin client device
05:49Selveste1 has joined #ltsp
05:50
<alkisg>
You mean that you use a normal PC as a fat client? That's not a problem
05:50
Anyway, gotta go. Bye all...
05:50
<sean74>
ok, thanks
05:50
good day

if I alter the chroot environment, do I have to rebuild the ltsp image?
05:55
<sweetpi>
yes
05:56
<rickogden>
thanks :)
05:57
<sweetpi>
nfs is best imho if you need to make changes often, you can always switch to nbd at a later point
05:58
<rickogden>
I'm still quite new to LTSP, so I'm not quite sure what you mean
05:59
<sweetpi>
i mean exporting the directory over nfs and mounting it instead of having to rebuild the image many times when you just want to change a config option in the chroot
06:00
<rickogden>
oh right, is there a setting for that somewhere?
06:01
<sweetpi>
no, you just need to change your boot options and export the directory
06:01
<rickogden>
ah right
06:03
<sweetpi>
instead of nbdroot you would have netboot=nfs nfsroot=serverip:/opt/ltsp/i386
06:03
<rickogden>
tbh I don't really mind rebuilding the image, certainly nicer on the network when we have 60 people logging in simultaneously
06:03
useful to know, thanks!

<Ghidorah>
Hello
08:40
<faranda>
Hi Ghidorah.. I have some question about my LTSP server
08:41
<Ghidorah>
I'll do my best to help
08:42
<faranda>
ltsp works perfectly for my local network
08:42
<Ghidorah>
ok
08:42
<faranda>
sometimes I need that the terminals are connected via VPN
08:43
for which I use freenx-server and nxclient
08:43
The problem is that when using NX, I lose the ability to mount USB devices
08:44
I use ltspfs for that...
08:44
<Ghidorah>
so you're trying to mount a USB device on a terminal while connecting via VPN?
08:45
<faranda>
yes.. through NX...
08:45vongrippen has joined #ltsp
08:46
<faranda>
in slow connection, NX works much better than simple X-ssh
08:46
<Ghidorah>
I'm affraid I do not know how to help with this
08:47
<faranda>
ok, thanks... i keep looking

is CUPS running?
10:42
rather annoying question, but ours crashing quite a bit.
10:42
s/crashing/crashes/
10:42
<sean74>
atkuepker: CUPS running? in client or server?
10:42
atkuepker: were you talking to me?
10:43
<atkuepker>
yeah. I'd assume server, but I don't run FatClient either, so i can't speak to that.
10:43
I'd imagine that CUPS would have to be running on the client if you were operating the FatClient, eh?
10:46
<sean74>
atkuepker: hmmmm
10:47
atkuepker: maybe
10:47
atkuepker: you suggest that i should install cups server on the client site?
10:48
atkuepker: do i need to add the printer_0_device in the /var/tftpboot/...../lts.conf?
10:48
<atkuepker>
I wouldn't think so unless you were running the FatClient chroot
10:49shamino has quit IRC
10:49
<atkuepker>
ours worked fine right out of the box without an lts.conf and CUPS on the server. But the CUPS service does crash a fair bit in a heterogenous network.
10:50
<sean74>
atkuepker: you meant that the CUPS service needs to be installed. sudo chroot /opt/ltsp/fati386 apt-get install cups??
10:50
atkuepker: something like that?
10:50
<atkuepker>
Not necessarily
10:50
are you running the FatClient chroot?
10:52
<sean74>
atkuepker: do you meant, chroot /opt/ltsp/fati386??
10:52
atkuepker: this is how is build the client. sudo ltsp-build-client --arch i386 --chroot fati386 --fat-client-desktop ubuntu-desktop
10:53
<atkuepker>
Ah, so you are running fat client.
10:54
<sean74>
atkuepker: when i load the system->administrator->printing. it keeps showing me the server ip instead of local host
10:54secayford has joined #ltsp
10:55
<atkuepker>
If it's already in the chroot, you might want to make sure it's running on the client. If it's not already there, I'll have to defer to the developers. I run about a dozen thin client installations here but no fat client.
10:57
<sean74>
atkuepker: how can i configure the thin client in order to use the printer attached to the device? maybe i can try the configuration on fat client
10:58
atkuepker: what do you meant by "already in the chroot"?

12:32
<Ynnek>
alkisg: yes.
12:32
<alkisg>
sean74: I'm not really sure if you have a thin or a fat client there. Maybe I could check with vnc when we both have some free time.

13:06ogra_cmpc has quit IRC
13:07
<johnny>
Ynnek, that only works if you enable some lts.conf variables and setup your syslog server on your server to accept connections from it
13:07
on your ltsp server*
13:08
<alkisg>
But you can also just switch to vt2 (SCREEN_02=shell) and run `cat /var/log/xxx`
13:08
<Ynnek>
johnny: thanks for your help
13:10
alkisg: perfect. But check all logs of thin clients from the server looks more efficient...

someone knows about problems with Ubuntu Karmic LTSP + Geode client + Xorg high CPU load?
15:00bobby_C has quit IRC
15:00
<Eghie>
am currently debugging that problem
15:00
cpu load gets 90% en LTSP sessions are terribly slow
15:00
but on another client, with another hardware it's blazingly fast
15:01
so, because Xorg gets 90% CPU, I think there lies the problem
15:06
<alkisg>
Eghie: do you have both italc + vino (the vnc server) running?
15:07
<Eghie>
alkisg: no, I don't have vino running
15:07Ynnek has quit IRC
15:07
<Eghie>
alkisg: are they normally fighting?
15:08
<alkisg>
Yes, and causing 100% cpu usage
15:08
So if that user has "remote desktop" enabled, then...
15:08
<Eghie>
although ica uses also port 5900
15:09
<alkisg>
Try to stop ica and see if it helps
15:10Ynnek has joined #ltsp

killed all processes with the name ica (ica-launcher and stuff also), but no effect
15:10
<alkisg>
OK, that's not it then
15:10
<Eghie>
port 5900 is not the problem, because now nobody listens to that port anymore
15:11
<alkisg>
So the same user on another (non geode) client has no problem?
15:11
<Eghie>
indeed
15:12
same server, same network, same cables, but other client has no problem
15:12
but if it's another geode client, it's the same problem again
15:12
<alkisg>
And if you use XSERVER=vesa?
15:12
<Eghie>
I could try
15:15ogra_cmpc has joined #ltsp

well, i heard that eventually grub2 will be able to do the same thing
15:34
by including their own better usb driver

but until then..

Grub2 will do a lot of things eventually, but until then, my old laptop will be completely unusable :)
15:35

hah :)
15:35
yes.. i meant but until then, at least you have something working

i did use grub2 for network booting at one point ...
15:47
even stuck a branch for support for ltsp...
15:48
although i think that was still using etherboot or gpxe to boot from
15:50
<alkisg>
Yes it has some pretty old etherboot version embedded
15:50
But it had some problems, I couldn't get it to properly boot and I was told on the mailing list that it's not usable yet
15:54
<johnny>
fedora still doesn't have grub2
15:54
<Lns>
yeah i went to a local lug last week about grub2 and they said it's not really production ready yet
15:54
<johnny>
and yet.. it's default in ubuntu
15:54
<Lns>
but of course! ;)
15:54
since 9.10
15:54
<johnny>
it's just a boot loader tho.. not sure why the hell it takes so log
15:54
long*
15:55
especially since it already worked before :)
15:55
<Lns>
johnny: think of all of the different things they must be compatible with.
15:55
<johnny>
sure.. but there must be some middle ground there
15:55
<Lns>
now we have SSDs, usb keys, VMs, 64-bit, new archs wanting to be supported, etc. etc.
15:55
<johnny>
between throwing everything out.. and reuing everything
15:55
Lns, sure, but that's not actually required for grub2
15:56
compatibility with grub1 in a cleaner fashion to allow for those things..
15:56
<Lns>
what isn't?
15:56
<johnny>
should have lead to a grub release much earlier
15:56
<Lns>
well i think it was one of those "this is old and unmaintainable" things
15:56
<johnny>
and then the rewrite takes longer than it should
15:56
rewriting from scratch is almost never the answer
15:56
<Lns>
johnny: well then patch grub1! =)
15:57

well i think they are past the point of doing that now

Or does it have -u '' hardcoded?

I was having a problem booting ltsp that I fixed by disabling acpi, but now I cant power down the computer. acpi works fine on the local os, so Im thinking I dont actually need to disable it. Any ideas?
17:37
<johnny>
try again without disabling it :)
17:38
<sweetpi>
hehe, ive tried that. and also pci=noacpi which should allow shutdown
17:39
<johnny>
i think the smarter people have already gone home for the day (weekend)

...try whatever acpi and apm variations you find there...
17:47
<sweetpi>
wow nice, i didnt know there were that many acpi options. thx
17:48
<alkisg>
E.g. pci=noacpi might boot your client while keeping shutdown working
17:48
Ugh sorry you've tried that one
17:48
(did it boot with *just* pci=noacpi?)
17:49
<sweetpi>
no
17:51
<alkisg>
Boot the same os as a thin client and locally, run lsmod and compare the results
17:51
Then try to make ltsp use the exact same modules as when it boots locally
17:51
(use the same distro version)
17:52* sweetpi thinks it will do the same thing
17:52
<alkisg>
Didn't you say it works fine locally?
17:52
LTSP uses modules=netboot, so it might have some differences there
17:53
<sweetpi>
yes, but an older version of ubuntu
17:53
<alkisg>
You can boot a live cd with the current version. Netboot it even.
17:53
<sweetpi>
i thought it might be the framebuffer, but i disabled it and it does the same thing
17:54
yeah that sounds better.. actually i already have the server setup for it
