bjfRAOF, after an a.m. dist-upgrade today, i find myself without X00:50
bjfRAOF, this is a thinkpad x301 with intel graphics00:51
RAOFReinstall ubuntu-desktop, everything's installable now.00:51
bjfRAOF, a daily iso *does* work00:52
bjfRAOF, will give it a whirl00:52
bjfRAOF, can you also fix my btrfs on the same system :-)00:52
RAOFbjf: Did you perhaps miss the u-d@ & u-d-d@ notification a couple of days ago that X upgrades would be broken until everything was rebuilt for the new X server? :)00:53
bjfRAOF, i saw the notice, thought everything was rebuilt (I was *wrong*)00:53
RAOFEverything (well, almost everything) that needs rebuilding has now been rebuilt.00:54
RAOFIn return, would you like to fix the frequent kernel oopses in iwlwifi? :)00:54
bjfRAOF, which kernel version you running?00:54
RAOF2.6.35-200:55
RAOFor possibly -100:55
bjfhmmm, if -1 try -2 but I haven't seen that problem00:55
RAOFHah.  I bet you also haven't been having kernel crashes every couple of days, either :)00:57
bjfi'm fighting a btrfs issue right now, gotta love these linux release candidates00:58
RAOFYou'd have a launchpad bug already if launchpad would accept ~255MiB vmcore apport attachments.00:58

ogasawarakamal: bug 553498 came up in the release meeting today ... but based on comment #52 from yourself, it seems this should be resolved for Maverick16:22

manjolag, looks like you are beating the heck out of emerald16:32
tgardnerogasawara, hmm, theres a lot of patch there, but mostly ripping out code16:33
ogasawarakamal: ok looks like that was upstream as of 2.6.35-rc1.  Since we've already rebased maverick to 2.6.35-rc2 I'm going to mark the Maverick task Fix Released.16:33
kamalogasawara: I agree16:34
ogasawarakamal: for lucid, have you tested with this patch backported?16:34
kamalogasawara: yes, I've applied exactly that change to lucid and published a test kernel, and have positive test results from myself and from other people on the bug report.16:35
lagmanjo: My build is finished16:36
kamaltgardner, ogasawara: any explanation why I see this patch with two different SHA ID's?  (the one you guys found also works in my trees).16:36

manjolag how did you get more priority over my build task... it virtually stopped all my builds16:36
tgardnerkamal, perhaps your repo is polluted. try 'git gc;git prune"16:37

tseliotmjg59: the F1 button acts as a video switch while Fn+F1 acts as F117:14
=== sconklin is now known as sconklin-afk
mjg59tseliot: Ok, so you should be getting KEY_SWITCHVIDEOMODE through the ACPI video driver17:16
mjg59Are you not?17:16
tseliotmjg59: no, I'm not. Nothing happens if I use the radeon driver instead of fglrx17:16
tseliotand no output in acpi_listen17:17
mjg59Well, then there's a bug somewhere17:17
mjg59I don't think it has anything to do with dell-wmi17:17
tseliotdo you think it can be the graphics driver?17:17
mjg59Can you send me the acpidump for the machine?17:17

tseliotmjg59: BTW I'm also booting with acpi_osi="!Windows 2009"17:21
mjg59Why?17:21
mjg59Oh, because otherwise it sends Windows+P?17:21
tseliotyep17:21
mjg59Ok, don't bother sending me the acpidump17:21
mjg59Eh. Actually, do17:21
tseliotI will17:22
mjg59mjg@redhat.com is probably the best17:22
mjg59But I suspect that the correct fix here is "Make sure windows+p does the right thing", since we're not going to modify the kernel to disable the Windows 7 OSI string17:22
tseliotmjg59: ok, I'll send it there, thanks17:22

tseliotapw: you may want to ask mterry the same question again17:44
tseliotnow that he's here17:44
apwmterry, where do we see a requirement for the return after the win-p in the windows spec17:45
mterryapw, oh, you're going to ask me hard questions.  let me try to find the reference for that17:46
mterryapw, jerone knows more on this than I do, will try to find him talking about it in email17:46
apwmterry, i've not even found a reference in any of his docs that says win-p should be generated.  only that pressing win-p produces that dialog and your button should produce the same one17:47
apwwhich is miles from must produce win-p17:47
apwwinlundn, i don't think i understand you17:48
winlundnunrelated to what you're talking about now, I see. My mistake17:49
apwwinlundn, ahh ok17:49
mjg59tseliot: Well, I see part of the problem17:55
mjg59Looks like Radeon needs to call the ATIF method17:55
mjg59I'll talk to AMD about that17:55
tseliotmjg59: thanks17:56
mterryapw, everything I know is in bug 539477.  Jerone says (comment #40) that he has a secret data sheet that recommends the logic he outlines in comment #39.   The one presentation he can link to has (slide 36) says that "modifying ACPI hot key to display Windows 7 projection hot key" is "highly recommended".  which doesn't talk about return key, but does imply that BIOS should report Super+P for the display key18:00
ubot2Launchpad bug 539477 in linux (Ubuntu) (and 4 other projects) "Video out hot key sends super + p + return on many upcoming Dell & HP systems (affects: 10) (dups: 1) (heat: 110)" [Undecided,Confirmed] https://launchpad.net/bugs/53947718:00
mterryapw, presumably Jerone can share the secret data sheet with you18:00
apwmterry, i think he has, and as i say i just cannot see what they are doing as mandated18:02
mterryapw, "what they are doing" means the return key?18:03
mterryapw, I haven't seen the data sheet.  You're saying that it's not even suggested?18:03
* winlundn is always going to look at acpi and go, ``Oh that.''18:03
apwmterry, i don't even see the wording meaning you need to win-p at all, cirtainly there was nothing saying anything about also hitting return for the user18:04
apwit is a god awful idea18:04
mterryapw, agreed.  :)  slide 36 has the language I quoted.  That doesn't strike you as suggesting Super+P?18:05
mterryapw, to my eyes it directly says as much18:05
apwit says what super-p will produce, and says any magic key should produce the same dialog18:05
apwi don't see words saying tehy are the same18:06
mterryapw, no, it says any magic key should "display win7 projection hot key"18:06
mterryapw, it doesn't say anything about a dialog there18:06
apwit says display, not type or send18:06
apwand even if i am very generous and accept that win-p is required18:06
apwread me the bit about return being required18:06
mterryapw, agreed.  But it also says hot key.  And if it was intended that the dialog come up for the magic key, it would be done on win7 side, no need to ask bios people to change anything18:07
mterryapw, so it sounds like they are asking bios people to change reported hot key18:07
mterryapw, (I mean, if MS wanted dialog to come up for old VIDEOSWITCHMODE key press, they could do it themselves, don't know why that request would be directed at BIOS people)18:08
apwi don't agree, but that is imeterial to my point which is the extra return is not mentioned, and that would be a sane thing to do in the win7 side if desired18:08
apwie if the dialog should be self answering why would win7 not do that, why would the bios need to be involved18:08
winlundnaye, metric18:09
mterryapw, well, Jerone says that the return behavior is clearly spelled out in his secret data sheet.  You say you've seen this sheet but don't agree.  I can't really add anything to this discussion18:09
mterryapw, except to say that BIOS's in the wild are doing this18:09
apwthat bios vendors do stupid things is the very definition of the breed18:10
* manjo going down for a reboot18:10
apwthere is almost no way to do anything sane with those semantics18:10
mterryapw, except to ape Win7 exactly (throw up a dialog, etc).  Which I agree is a crazy requirement to have to meet18:10
winlundnmterry: yes, from what I understand that's bridging that where it's un-needed18:12
apwtgardner, the first rebuild just completed, looking good18:23

bladernrany way to reset that without a reboot?  Because, according to my logs (64 bit 10.04) I have been running either a few thousand seconds or over 18 billion seconds...20:19

ogasawarakees: yep, we rebased to 2.6.35-rc2 a few days ago20:37
ogasawarakees: you should be able to git fetch origin20:37
tgardnerkees, if you've no local changes then 'git fetch origin master;git reset --hard FETCH_HEAD'20:38

* ogasawara lunch20:42
keestgardner: and how do I rebase local branches that are based on the now-rebased maverick?20:47

tgardnerkees, if they are in the same repo20:48
keesthat fails for me.20:49
tgardnerrebase conflicts?20:49
keesnot from my changes.  my change was a single commit on top of regular maverick, and now it's yelling about merge conflicts in debian/*20:49
lag-mobileCan you do cross-repo rebasing?20:50
kees$ git rebase maverick20:50
keesFirst, rewinding head to replay your work on top of it...20:50
keesApplying: UBUNTU: Fold down debian for ubuntu-m20:50

kees<stdin>:160857: trailing whitespace.20:50
kees....20:50
kees*boom*20:50
keesand that rewind took a looong time20:50
keesI assume it tried to find the branch point and re-applied the entire old maverick stack to the rebased maverick stack.20:51
keeshow do I tell it "throw away all of this except my top commit" ?20:51
tgardnerkees, ah. then the simplest thing to do is restore your original branch and save off your local patch; git checkout -f YOUR_BRANCH;git format-patch -1;git fetch origin master;git reset --hard FETCH_HEAD;git am 0*20:51
tgardnerkees, does that make sense?20:52
keestgardner: yeah.  though it seems a bit clumsy.  I was hoping to automate this, so "-1" won't always be correct.  hmmm20:53
tgardnerkees, it is clumsy, but its conceptually simple (for me at least)20:53
keesyeah20:53
keestgardner: oh, actually, can't I use FETCH_HEAD as the cut-off for doing the format-patch, since it was set during the last fetch?20:58
tgardnerkees, I'm not sure that makes sense because your local patches are relative to HEAD.20:59
keeshm.21:00
tgardnerkees, once we stop messing with the debian cruft then rebasing will likely work better.21:00
keesI mean, if I do this:  git checkout master; git fetch origin master;git reset --hard FETCH_HEAD; git checkout -b test-branch; *work*commit*; git checkout master; git fetch origin master;git reset --hard FETCH_HEAD; git checkout test-branch.  isn't FETCH_HEAD here equal to where I started my work? as in FETCH_HEAD through HEAD are my local patches, so I could do git format-patch FETCH_HEAD; git fetch origin master;git reset --hard FETCH_HEAD;git am21:02
tgardnerkees, you're making my head hurt.21:03
* kees blames git21:03
keesalso, I think git am is lossy, in that it starts ignoring text after a --- line21:03
tgardnerkees, which is why I never use it unless its been a 'git format-patch' created file21:04
keeswell... i have format-patch'd patches that include --- for the purpose of having "am" drop the text after it when someone upstream takes my patch (i.e. I have the patch version history after ---), but I don't want to lose it locally.  that said, I think rebase might be able to do a "from, to" kind of a thing here.21:05
