| highvoltage | stgraber, mgariepy: any comments on http://edubuntu.org/sites/default/files/banner-slideshow/precise-release.html for a release banner on edubuntu.org? http://edubuntu.org/sites/default/files/banner-slideshow/precise-release.html | 14:37 |
|---|---|---|
| stgraber | highvoltage: looks good | 14:37 |
| highvoltage | stgraber: I also think that we should have an "About Edubuntu" paragraph at the end of the announcement | 14:38 |
| * highvoltage adds it so long | 14:38 | |
| stgraber | highvoltage: good idea, you can probably copy/paste some of what I put in the wiki announcement | 14:38 |
| highvoltage | hmm, link? | 14:38 |
| stgraber | highvoltage: https://wiki.ubuntu.com/PrecisePangolin/ReleaseNotes/Edubuntu though looking at it again, there's only the first sentence you might re-use | 14:41 |
| highvoltage | great | 14:41 |
| highvoltage | stgraber: I'm going to change the spin slightly and assert Edubuntu more as a project than a product | 14:44 |
| mgariepy | highvoltage, it looks good :) | 14:45 |
| stgraber | highvoltage: I'll need to get the weblive VMs to run with libeatmydata ... it's so slow to build with all the fsyncs() and it's not like I care about the data | 14:49 |
| highvoltage | heh, libeatmydata avoids the fsyncs? :) | 14:49 |
| stgraber | yeah, it restores your system to pre-ext4 fiasco where you hope that the fs autosyncing is enough to get your data on disk | 14:50 |
| stgraber | but prevents dpkg (well, everything) from calling fsync everytime they write to disk | 14:50 |
| highvoltage | doesn't data=writeback do that already? | 14:50 |
| stgraber | highvoltage: isn't that only for metadata syncing? | 14:51 |
| highvoltage | from what I understand, data=writeback basically makes it work like reiserfs and if you have a power outage or something, you just travel back in time and lose all recent writes | 14:52 |
| highvoltage | the quick usage instructions doesn't seem to disagree with either of us, but it does seem like data=writeback is the "ldm_directx" of ext4 :) | 14:55 |
| highvoltage | http://kernel.org/doc/Documentation/filesystems/ext4.txt | 14:55 |
| highvoltage | it's interesting how increasing the journal size could increase performance. I just go ahead and disable it completely on slow disks, like on my acer one. | 14:56 |
| highvoltage | I've also had some success with commit=60 on slow disks where I wouldn't particular care losing a minutes worth of work (like also on the netbook) | 14:58 |
| highvoltage | (but I'm sure you know about all of that already :p) | 14:58 |
| stgraber | apparently I need to use cache=none on my VM disk | 15:01 |
| stgraber | that should save quite a bit of cpu by avoiding use of the host cache | 15:01 |
| stgraber | (I'm giving a partition directly to the VM) | 15:01 |
| highvoltage | stgraber: mgariepy, alkisg, (and others): we have an edubuntu meeting at 19:00 UTC today, will you be able to make it? | 17:27 |
| stgraber | should be | 17:28 |
| alkisg | highvoltage: I don't think I can make it | 17:28 |
| alkisg | highvoltage: one idea I'd like to discuss for 12.10 is that the edubuntu dvd could support ltsp fat clients with the existing squashfs image now | 17:29 |
| alkisg | This would make the dvd smaller, the clients boot faster, and it would support fats along with thins | 17:30 |
| highvoltage | alkisg: yeah knoppix does that and I always thought it was really cool | 17:30 |
| highvoltage | ah you mean thin clients too, ok. | 17:30 |
| alkisg | Now we have a chroot in the dvd | 17:30 |
| alkisg | Instead of that, we could use the whole casper squashfs image as the chroot | 17:31 |
| highvoltage | alkisg: and what happens when we want to install LTSP? | 17:31 |
| alkisg | We'd need to have both ltsp-server and ltsp-client installed in the dvd for that to work | 17:31 |
| alkisg | We just remove ltsp-client in that case | 17:31 |
| highvoltage | I mean, when we install LTSP during the system installation? | 17:31 |
| highvoltage | currently the installer uses the chroot that is shipped on the dvd for that | 17:31 |
| alkisg | Two ideas: | 17:32 |
| alkisg | 1) use the squashfs image of the cd, | 17:32 |
| alkisg | or better yet, | 17:32 |
| alkisg | 2) just clone the server disk | 17:32 |
| alkisg | After ubiquity finishes, we can run ltsp-update-image --export-root | 17:32 |
| alkisg | That uses the server disk, while cleaning it up a bit | 17:32 |
| alkisg | (I've implemented it as part of ltsp-pnp, putting it upstream currently, will finish in a few weeks) | 17:33 |
| alkisg | So people would have support for thin and fat clients out of the box and even with a smaller DVD | 17:33 |
| highvoltage | server's disk? as in the server's /? | 17:33 |
| alkisg | Yes | 17:33 |
| alkisg | So it automatically takes the language settings and everything | 17:34 |
| alkisg | The user accounts and other sensitive data are removed of course before being put in the chroot | 17:35 |
| alkisg | Another thing I'd like in the 12.10 Ubuntu CDs (and edubuntu DVD) is ipxe | 17:36 |
| alkisg | Would allow people that don't have bios netboot option to use the edubuntu dvd to netboot all clients | 17:36 |
| alkisg | I think I've filed a bug report for that and it received positive comments... | 17:37 |
| highvoltage | ok, interesting | 17:42 |
| stgraber | highvoltage: can you help testing the amd64 image? weblive is taking me longer than expected | 18:12 |
| highvoltage | stgraber: on it... | 18:12 |
| highvoltage | (syncing now, I can't think that it would take long) | 18:13 |
| stgraber | highvoltage: Ideally, do the following: | 18:13 |
| stgraber | - Boot to live session in a non-english language | 18:13 |
| stgraber | - Start LTSP-Live | 18:13 |
| stgraber | - Login from a thin client => check session language | 18:13 |
| stgraber | - Shutdown thin client | 18:13 |
| stgraber | - Install to disk in another language | 18:14 |
| stgraber | - Use manual partitioning | 18:14 |
| stgraber | - Use LTSP + gnome-fallback | 18:14 |
| stgraber | - Unselect tertiary | 18:14 |
| stgraber | - Select encrypted home | 18:14 |
| stgraber | That's the easiest way of covering 95% of the code paths (just missing OEM) | 18:14 |
| highvoltage | ok | 18:15 |
| stgraber | if that all works, the image is good to ship | 18:15 |
| highvoltage | stgraber, mgariepy: should we do a quick release roundup in #ubuntu-meeting since we have a meeting scheduled? | 19:02 |
| stgraber | sure | 19:02 |
| highvoltage | great. | 19:02 |
| stgraber | highvoltage: install done | 19:40 |
| stgraber | highvoltage: doing some post-install test of the codec fix | 19:40 |
| mhall119 | stgraber: highvoltage: I linkified some of the project names on https://wiki.ubuntu.com/PrecisePangolin/ReleaseNotes/Edubuntu if you want to look over it | 19:40 |
| highvoltage | I'm getting some weird graphics issues on ltsp-live, it looks like some weird compositing issues where any square is just drawn as a triangle | 19:40 |
| stgraber | highvoltage: what video card are you using? | 19:41 |
| stgraber | I'm using cirrus here and it looked good, using Precise's kvm | 19:41 |
| highvoltage | stgraber: it's one of those good HP thin clients (with the intel mobile 4 iirc cards) | 19:42 |
| stgraber | oh, ok, that's weird | 19:42 |
| highvoltage | indeed, especially since I've never seen that so far on precise | 19:42 |
| highvoltage | my checksums match. this is the right iso, right? http://cdimage.ubuntu.com/edubuntu/dvd/current/precise-dvd-amd64.iso | 19:43 |
| stgraber | 20120425 | 19:43 |
| highvoltage | ok they're the same, at least | 19:44 |
| highvoltage | well, ltsp-live itself works at least | 19:44 |
| stgraber | yeah, just some weird ltsp issue to look into | 19:45 |
| stgraber | apparently unity 3d is broken too, some people reported blank screens on LTSP unless you explicitly select ubuntu-2d | 19:45 |
| stgraber | so much for 16bit just working I guess... | 19:45 |
| stgraber | the dash overlay on the ubuntu wallpaper in 16bit is also extremely ugly, thankfully Edubuntu's wallpaper is quite a bit better | 19:46 |
| highvoltage | ok I'm on to installing... the edubuntu slideshow looks cool in French :) | 19:48 |
| stgraber | right, so I confirmed the codec fix, just checking that post-reboot oem still works and then waiting for your install result and will be consider as good to relesae | 19:49 |
| stgraber | considering the few LTSP issues I've seen so far, I think we should prioritize these before any 12.10 feature work so we have them all fixed for 12.04.1 | 19:50 |
| stgraber | we won't be able to revert the 16bit change in an SRU but we should at least make sure the session always open fine and anything crashing because of 16bit gets fixed | 19:51 |
| Ziron | Is the 12.04 release still on schedule for tomorrow? | 19:58 |
| highvoltage | yep | 20:00 |
| highvoltage | there's been some hickups but it shouldn't cause a delay | 20:00 |
| stgraber | highvoltage: still installing? | 20:18 |
| highvoltage | stgraber: yep, just checked | 20:19 |
| highvoltage | stgraber: done, and I'm passing it despite the display problems I had in LTSP Live | 20:29 |
| stgraber | k | 20:30 |
| highvoltage | stgraber: I'll recheck that and file a bug if I can reproduce, if it's valid I guess we can SRU it for 12.04.1 | 20:30 |
| stgraber | yeah, if we can reproduce, we should fix and SRU | 20:30 |
| stgraber | I don't have any LTSP hardware here so I'll need to wait to be back home before I can test any of that | 20:30 |
| highvoltage | the installed system didn't have that error on LTSP | 20:31 |
| stgraber | oh really? that's very odd then | 20:31 |
| highvoltage | yep. perhaps something didn't reset properly on the thin client. | 20:31 |
| stgraber | because we don't really change anything in lts.conf and the only thing we do to the image is run ltsp-update-image | 20:31 |
| highvoltage | yep | 20:31 |
| stgraber | yeah, sounds like graphical memory corruption or similar random weirdness | 20:32 |
| highvoltage | but that's why I have to check again, perhaps it happens intermittently | 20:32 |
| stgraber | anyway, can you post your results on the tracker before I move it? | 20:32 |
| highvoltage | or perhaps it was just a fluke | 20:32 |
| highvoltage | the tracker still says rebuilding though? | 20:32 |
| stgraber | highvoltage: http://iso.qa.ubuntu.com/qatracker/milestones/214/builds/16053/testcases | 20:33 |
| stgraber | the one in Precise Final is disabled until the new one in Precise Pre-release is tested | 20:33 |
| highvoltage | ok | 20:33 |
| stgraber | once you post your results I'll replace the current one in Precise Final by the one currently in Pre-release | 20:33 |
| highvoltage | done | 20:33 |
| stgraber | (yeah I know kind of complicated, skaet's idea ;) I think we'll discuss that at UDS and decide not to do it again) | 20:34 |
