| |
11:36 | <alkisg> With the new "embed a script" feature of rom-o-matic, dhcp-less booting got very very easy
| |
11:37 | I can just download a gpxe image from rom-o-matic, add a static IP for the client and for the ltsp server, and I'm done...

| |
12:02 | <alkisg> hi
| |
12:03 | <davemir> alkisg: I have installed the iTALC
| |
12:04 | alkisg: but when the program starts I get a message
| |
12:05 | alkisg: The message makes: No authentication-keys were found or your old one were broken. Please create a new key-pair using ICA.
| |
12:06 | <alkisg> davemir: I'm programming something now, I don't have time for italc support. Could you please ask generally in the channel, for whoever may be available to help you?
| |
12:07 | <davemir> ok
| |
12:07 | alkisg: thanks
| |
12:08 | <alkisg> (btw I've stopped using italc since some months because it was crashing too often)
| |
12:10 | <davemir> alkisg: This program is no substitute
| |
12:17 | Someone could help me with a problem I have with iTALC program

13:27 | <myjess> help with lucid lynx please?
| |
13:28 | my old laptop that i was using as a test bed drops the screen after a few secs of the ubuntu name on the scr4en after boot. I think something is driving the screen to resolutions it cannot handle. Putting the xorg line into lts.conf with a resolution of 800x600 does not help.
| |
13:29 | ltsp does come up in a virtualbox machine and although I do not know what is telling X the kmax freq of the virtual screen, the virtual screen is sitting at 800x600 85hz. This is way too much for my opld laptop. I need 800x600 @ 60Hz
| |
13:30 | This seems to have only occurred after upgrading to lucid alternate fresh install.
| |
13:30 | chipset on laptop is intel 855gm
| |
13:31 | Thanks for any help.
| |
13:31 | <alkisg> Ouch
| |
13:31 | Put nomodeset on pxelinux.cfg/default
| |
13:31 | <myjess> ok. will try that.
| |
13:31 | <alkisg> My laptop with 855 doesn't load X with the current lucid kernel
| |
13:31 | Let me get you the bug report..
| |
13:32 | See comments 48, 49 and 50 here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/511001
| |
13:32 | That's for standalone lucid, but of course the kernel problems also affect ltsp clients.
| |
13:33 | So the best solution is to use that patched kernel that is mentioned on post #49.
| |
13:35 | <myjess> thanks, but I am going to go nuts if that means another build, it takes too long, and then I have to customise it each time for stuff I want in it.
| |
13:35 | Is there a wiji on NFS on lucid or karmic. I cannot find one. I need to use NFS until I get the bugs sorted.
| |
13:35 | <alkisg> You don't need ltsp-build-client. Just to manually install that kernel, ltsp-update-image, and ltsp-update-kernels
| |
13:36 | See the "reverting to nfs" paragraph in https://help.ubuntu.com/community/UbuntuLTSP/LTSPWithoutNFS
| |
13:38 | * alkisg is using a separate partition as /opt/ltsp/i386, and exports that directly with nbd, without ever running ltsp-update-image and without using nfs. | |
13:41 | ogra_cmpc has quit IRC | |
13:43 | <myjess> is there a quickl way to install that kernel and all it's other bits without picking each from from aptitude?
| |
13:43 | ogra_cmpc has joined #ltsp | |
13:45 | <myjess> Not to worry, the 4 files are coming down now.
| |
13:46 | <alkisg> Try the nomodeset while they're downloading
| |
13:46 | It should work, but then crash if you try to watch video with xv
| |
13:46 | Ah no, with the latest lucid kernel it won't work. Only with -19 or -20 it will.
| |
13:46 | So never mind, don't even test nomodeset...
| |
13:46 | <myjess> nomodeset didn't make any diff. The screen kinda goes as if it is greying out and then nothing.
| |
13:47 | <alkisg> Right, and also keyboard hangs and capslock isn't working etc etc
| |
13:47 | <myjess> I tried that paragraph, course, I have to know what I am doing as in all things linux based, any docs are written with a view to the person understanding everything that isn;t actually written but needed also.
| |
13:48 | and with that paragraph, I don;t know the rest of what I am supposed to be installing/using.
| |
13:48 | <alkisg> What paragraph?
| |
13:48 | The bug report?
| |
13:48 | <myjess> No, the one you mentioned for NFS.
| |
13:49 | <alkisg> Feel free to edit the wiki to make it clearer
| |
13:49 | <myjess> I would but I don;t know what else I am supposed to be doing along with putting nfs server in and modifying the exports file, I mean how does the boot know to go looking for NFS other than NBD?
| |
13:50 | <alkisg> Ugh. Someone changed it and removed useful stuff there.
| |
13:51 | <myjess> Yeh, linux experts expect all of the rest of us to be linux experts.
| |
13:51 | Kicer86 has quit IRC | |
13:53 | <myjess> Anyway, I did an apt-get install on the 4 files that had 2.6.34rc51* and then did the ltsp-update-kernels, but the kernels are still at 32.22. Obviously I have to do more to get 2.6.34rc51* in as a kernel.
| |
13:53 | <alkisg> Here's a history of that page: https://help.ubuntu.com/community/UbuntuLTSP/LTSPWithoutNFS?action=recall&rev=12
| |
13:54 | ...but the person that changed it says that it doesn't work because of some bug. I haven't tried nfs on lucid so I don't know what's the deal with that.
| |
13:54 | <stgraber> he's probably referring to some mountall bug
| |
13:55 | though that's either solved or quite easy to workaround
| |
13:55 | (never tried NFS on lucid though)
| |
13:55 | <myjess> what else do I have to do to that modified kernel other than apot-get install *2.6.34rc51* ?
| |
13:55 | <alkisg> stgraber: I wonder why he removed all he useful stuff about root_write_method="bind_mounts", BOOT=nfs etc though
| |
13:55 | myjess: ls -lha /opt/ltsp/i386/boot
| |
13:55 | What do you have there?
| |
13:56 | <stgraber> alkisg: no idea, especially as I don't think we changed that upstream so it's still relevant for ubuntu ...
| |
13:57 | <myjess> blast, the capslock has stuck via my remote desktop viewer. Only thing that cures that is a reboot of the server.
| |
13:57 | I*'ll have to run that ls -lhs command after the image is updated, yeh I knopw, the image shouldn;t have been upddated yet cos the new kernel doesn;t seem to be there.
| |
13:58 | server is in the attic you see, and I am in the kitchen
| |
13:58 | Thank gawd for my old ERIC Lights out card.
| |
14:01 | hmmm, the rc51 kernel has taken as far as the server is concerned but not in the /var/lib/tftpboot/ltsp/i386 dir.
| |
14:02 | <alkisg> Erm, did you install that on the chroot or on the server?
| |
14:02 | You were supposed to install it to the chroot, for the client...
| |
14:02 | <myjess> on the server.....
| |
14:02 | hahahahaha
| |
14:02 | riddy 'eck.
| |
14:02 | ok. let me have another go, but does it not have to be in /var/lib/tftpboot.... etc?
| |
14:03 | surely it has to be there cos it boots from the network?
| |
14:03 | <alkisg> Yes, it need to be in the tftp dir and on /opt/ltsp/i386/boot as well
| |
14:07 | <myjess> ok. Your ltsp-update-kernel script, does it take account of files with non standard kernel naming convention?
| |
14:07 | johnny has left #ltsp | |
14:08 | johnny has joined #ltsp | |
14:09 | <myjess> never mind. I just learned something new again, the kernel files are taken from the /opt/ltsp/i386 files and put into /var/lib.
| |
14:10 | so me putting them in the i386/boot dir mean't that your script pulle dthem from there and stuck them in /.var/lib etc....
| |
14:12 | johnny has left #ltsp | |
14:21 | <myjess> hhmmmm, something has broken.
| |
14:22 | could have been all my customisations before the image update. It has dropped me to initramfs (busybox)
| |
14:22 | <alkisg> Did you try the nfs stuff? Do revert that back...
| |
14:25 | <myjess> Yeh, that's next step in the long chain of events, thanks.
| |
14:27 | ok.Thanks for tonight. Looks like I have to go the NFS route. It's such a pity there was no way to log what was happening after the booted kernel did it's post.
| |
14:29 | I took out splash and quiet from the default file. It seems to do a good bit of booting until the screen goes blank and it crashes.
| |
14:29 | johnny has joined #ltsp | |
14:36 | <alkisg> myjess: does it boot the new kernel or the old one?
| |
14:36 | Did you run ltsp-update-image and ltsp-update-kernels?
| |
14:39 | <myjess> I did both. No way that I can see to tell what kernel is loading, but the vmlinuz shortcut if to the rc51 kernel so I assume it is booting that one.
| |
14:40 | For nfs, should there always be, no matter what, an ltsp-client-setup file in /opt/ltsp/i386/etc/default?
| |
14:40 | Cos there isn;t
| |
14:40 | when I say shgortcut above, I mean linked of course.
| |
14:44 | ltsp-client-setup is not in /opt/ltsp/i386/etc/default, it is in the init.d subdir of etc. The wiki is wrong in that respect.
| |
14:44 | Patina has quit IRC | |
14:47 | <alkisg> So what do you have in `ls -lha /var/lib/tftpboot/ltsp/i386` ?
| |
14:47 | johnny has left #ltsp | |
14:50 | <myjess> 32.22 kernels and 2.6.34rc51 kernels.
| |
14:52 | I cannot go any further with that rev12 LTSPnoNFS wiki. It mentions ltsp-client-setup that are not in the location mentioned in the wiki, not is there any root_write_method in any ltsp-client-setup file to be modified.
| |
14:52 | <alkisg> myjess: so if you put SCREEN_07=shell in lts.conf, it boot fine (without X)?
| |
14:52 | <myjess> let me try.
| |
14:52 | <alkisg> Also try with SCREEN_07=vesa.
| |
14:52 | er sorry
| |
14:52 | XSERVER=vesa (different try)
| |
14:58 | <myjess> I see running nfs-top and then mount aufs on root failed. Then after a few secs it switches to colour frame buffer device 128x45
| |
15:00 | then I cannot read the start of the lines but something is not found. Try passing init= bootarg.
| |
15:01 | then it drops to busybox.
| |
15:01 | <alkisg> That sound like nfs-related problems... it's difficult to debug 2 things at once.
| |
15:01 | <myjess> I haven't done anything NFS apart from install the server and put the export line in. I cannot do anymore cos the wiki is wrong.
| |
15:02 | chupacabra has quit IRC | |
15:02 | <myjess> let me remove the rc kernels, go back to 32.22 and see what happens.
| |
15:02 | <alkisg> What do you have in pxelinux.cfg/default?
| |
15:03 | !pastebo
| |
15:03 | <ltspbot> alkisg: Error: "pastebo" is not a valid command.

15:08 | <alkisg> I don't get it. Without "quiet splash" there it shouldn't change any video modes while still at the initramfs.

15:10 | myjess: why do you have ipappend 3?
| |
15:10 | vagrantc has joined #ltsp | |
15:10 | <myjess> cos it says somewhere we have to have it...
| |
15:10 | <alkisg> Only on weird dhcp setups
| |
15:11 | Not on regular ltsp servers...
| |
15:11 | E.g. if you're using your router as a dhcp server etc...
| |
15:11 | <myjess> yeh, well, I have a dhcp router and then I use dnsmasqd
| |
15:11 | dnsmasqd on the ltsp server.
| |
15:12 | <alkisg> Got it. Try to remove that autoconf=dhcp parameter there, udhcp is broken on Lucid.
| |
15:12 | <myjess> seems to work, only diff is that the Ip changes between boot and later.
| |
15:12 | so what do I put in it's place.
| |
15:12 | <alkisg> OK, if you tried it and it works, leave it
| |
15:12 | E.g. on cisco routers it only works for 1 PC, the others hang.
| |
15:12 | It depends on your router's dhcp server. Anyway.
| |
15:13 | <myjess> BTW, booting up on vbox shows me "No init found. Try passing init= bootarg."
| |
15:13 | markit has joined #ltsp | |
15:13 | <myjess> before it drops to busybox.
| |
15:14 | <markit> hi, any suggestion for a thin client that works fine and has graphic power enough to have "composition" enabled?
| |
15:15 | for instance, I'm trying a "yashi" that looks good, but seems can't work with 1920x1080 as thin client (works fine booting kubuntu on it's own), and in any case is slow with video performances
| |
15:34 | runout has quit IRC | |
15:43 | <myjess> alkisg: fyi. Going back to kernel 32-22 allows ltsp to boot to tty screen 07.
| |
15:44 | <alkisg> myjess: it doesn't boot at all with the newer kernel?! Did you properly install it?
| |
15:44 | Or did you just copy it from the server?
| |
15:45 | And, how did you go back? With a file copy? Or with removing the kernel, ltsp-update-kernels, ltsp-update-image etc?
| |
15:45 | <myjess> i did the chroot which is your script, then did an apt-get install on 4 files, 2 of which were generic.
| |
15:45 | then i exited chroot and did ltsp-update-kernels
| |
15:46 | <alkisg> ? how did you find that kernel with apt-get?
| |
15:46 | It isn't on the repositories...
| |
15:46 | <myjess> and then update image
| |
15:46 | <alkisg> You'd need to download it and install it with dpkg, or use add-apt-repository...
| |
15:47 | <myjess> as per the post you gave me, i added that guys ppa repo while in chroot before i did the apt-get install.
| |
15:47 | <alkisg> And what do you mean "chroot which is your script"?
| |
15:47 | <myjess> you have that chroot script in a wiki which i use.
| |
15:47 | <alkisg> OK
| |
15:47 | And how did you remove it?
| |
15:49 | <myjess> but i didn't know if I should have only apt-get the generic files, so i apt-get the 4 of them which had the latest rc number on them.
| |
15:49 | i removed them using apt-get remove, i then delered any bad links and recreated them in th chroot
| |
15:50 | <alkisg> Hmmm ok, weird
| |
15:50 | <myjess> I then exitedthe chroot and did ltsp-update-kernels and then update image.
| |
15:50 | <alkisg> Can you run `lspci -nn | grep VGA` on the client? (boot it with SCREEN_02=shell)
| |
15:50 | (or SCREEN_07=shell)
| |
15:51 | <myjess> not at mo i'm afraid. too late at night now. have to put children to bed. I'll try doing that 2moro when I get time.
| |
15:52 | Im in the uk.
| |
15:52 | <alkisg> ok
| |
15:52 | Good night
| |
15:52 | <myjess> yeh, bye.
