* hyperair wonders if anyone here has had issues with plymouth..00:43
hyperairer i mean mountall + plymouth00:44
hyperairfsck seems to hang00:44
Picibug 57170700:46
ubottuLaunchpad bug 571707 in mountall "fsck at bootstrap is too slow" [High,Confirmed] https://launchpad.net/bugs/57170700:46
arandhyperair: I just posted a workaround in description ;)00:50
hyperairarand: i tried that, it didn't seem to work very well for me.00:51
hyperairarand: in particular, did you try watching your hard disk light?00:51
hyperairarand: the hard disk light turns off and stays that way after 80%00:51
arandhyperair: And spoke to keybuk, which said that it will likely take acouple of weeks before it will be addressed..00:51
* hyperair sighs00:51
hyperairlucid's in a pretty sad state eh..00:52
arandhyperair: Yes, that's the same as I had I think.00:52
hyperairarand: does your hd light come back on when you switch ttys?00:52
arandhyperair: We've gone from no sound in karmic to no boot in lucid, it's not a good trade...00:53
arandhyperair: I could test I guess, I'm using a virtualbox for it.00:53
hyperairarand: no sound in karmic?00:53
hyperairarand: i had plenty of sound.00:53
arandhyperair: Yea, me too, but that seemed to be the one common bug that people saw in karmic.00:55
hyperairarand: but what was the cause of the issue?00:56
hyperairhmm maybe it was pulseaudio hanging, it seemed pretty prone to hanging in karmic.00:56
arandhyperair: A couple of things, the old kernel on upgrade, the simple volume muted... At least my impression of karmic was that it was the "nosound" release, if naming from issues.00:58
hyperairlol00:58
hyperairkarmic was that golden release for me.. =\00:58
hyperairbesides intrepid00:58
hyperairjaunty was shit.00:58
hyperairlucid... *groan*00:59
hyperairwell i expect lucid.1 will be better.00:59
arandIn hindsight, plymouth might not have been the bestest... But then again, it was tried and discarded in karmic, so it made a whole lot of sense to push it now or never...01:02
hyperairon the contrary.01:04
hyperairwe should have pushed it in karmic01:04
hyperairthat would have made for a solid LTS.01:04
hyperairwhat we have now is a LTS full of partially implemented changes.01:05
arandYea, but a very unkarmic koala though...01:05
hyperairone is plymouth. another is the initramfs-tools resume script. and yet another is the application indicators, as not all the apps have been ported over to use them yet01:06
arandHmm, fsck halts at 70% and HD activity is null.01:06
hyperairye01:06
hyperairnow try switching vts01:07
hyperairand check the HD activity01:07
hyperairdoes it return?01:07
arandstill no activity01:07
arandwhen switching back to splash it's up to 90%01:08
hyperairhmm01:08
hyperairinteresting01:08
hyperairdoes it go past 90%?01:08
hyperairi fell asleep at 90% and just ctrl+alt+del'd my way out01:08
jdong*cringe* ah, doesn't all this parallel startup bring back memories of Windows XP bootup problems?01:08
arandAnd then switching back to VT, and it boots in 10 seconds01:09
jdong"ah it's hanging at the blue screen with the cursor and nothing's happening!"01:09
arandSo it seems it takes two VT-switches to get it past... *scratches head*01:09
arandAnd if I switch to early, the fsck is interrupted...01:11
hyperairjdong: oh yay we're finally reaching where windows XP was... er how many years ago? =p01:11
hyperairlol01:11
jdonghyperair: ;-)01:13
jdonghyperair: well we still have to figure out how to actually move blocks around ;-)01:14
hyperairjdong: blocks?01:14
jdonghyperair: http://jdong.mit.edu/~jdong/ureadahead-pack.svg01:14
jdonghyperair: that's the disk access pattern during bootup for Ubuntu ;-)01:14
hyperairwhoa.01:14
jdonghyperair: Windows since XP on idle will move all boot blocks together to the front of the disk.01:14
hyperairinteresting.01:14
=== nobawk|away is now known as nobawk
jdonghyperair: and Vista/7 takes it further by using some fancy machine learning algorithm to lay out the disk01:15
hyperair._.01:15
hyperairinteresting.01:15
jdong(and prefetch things into cache before they're asked for)01:15
hyperairsounds like they're ahead of us.01:15
jdongso hehe it's interesting to see Ubuntu walk down that path.01:15
hyperairheh01:15
jdonghyperair: well why else does a 20GB Windows 7 install boot pretty much the same speed as a 1.2GB Ubuntu install? :-/01:16
hyperairjdong: good point.01:16
hyperairwell we still boot much faster than vista and xp though01:16
hyperair\o/01:16
hyperairdespite not using far-fetched algos01:16
jdongwell sure, but that's like saying my lawnmower gets better fuel economy than a ferrari ;-)01:17
hyperairi imagine if we did something like that, we'd break our 10-second goal01:17
hyperairjdong: well said =p01:17
hyperairso we should have something like this for the next gsoc01:18
jdonghyperair: yeah I think that'll be our next step. at least the ability to statically use ext4 defrag APIs to move boot files together.01:18
hyperairbasically some hack that allows a userspace program to tell the kernel to shift these blocks where01:18
jdonghyperair: and in the future, the ability to dynamically do this via btrfs01:18
hyperairooh e4defrag huh01:18
hyperairyay btrfs01:18
arandAw.. what on earth, it doesn't work with normal VT-switching, I need to ude ctrl+al+arrow, and do it twice for it to work properly, ...the fish!?01:20
arandHang on, not even that, just arrowkeys works... I wonder if plymouth interprets arrowkeys in some special fancy way..01:22
hyperairthe "C" doesn't work for me01:24
arandhyperair: No, seems like plymouth itself is almost gone at this point01:28
hyperairarand: heh?01:31
hyperairhmmm i discovered something.01:34
hyperairit seems that X has a tendency to hang under some circumstances if started without "splash"01:35
arandHorray for more bugs!01:42
crimsunpolemic users always make me a sad panda.03:26

ghostcubeanyone from the ppa nvidia vdpau team here?20:12
alkisgMy package contains a twisted module. I install it with the distutils » setup() » py_modules variable, and it goes to /usr/share/pyshared/twisted/plugins/myplugin.py. But in order for it to work a symlink is also needed in /usr/lib/python2.6/dist-packages/twisted/plugins/myplugin.py. What's the normal way to create that symlink? I can't find it in any docs...21:22
