dholbachgood morning07:49
jodhI've updated the wiki with details of dual-booting with MultiROM: https://wiki.ubuntu.com/Nexus7/Installation#Details_of_installing_MultiROM_and_Modified_Recovery_to_Enable_Dual-Boot. Would be great if someone could "test" this section (and maybe add screenshots ;-)08:41
dholbachjodh, I made a tiny few little changes to the doc: https://wiki.ubuntu.com/Nexus7/Installation?action=diff&rev2=28&rev1=2709:30
dholbachjodh, trying to boot raring-preinstalled-deskto give me "Error - Kexec-hardboot support required to boot this ROM. Use kernel with kexec-hardboot support. Touch anywhere to close"09:31
dholbachbooting "Internal" seems to work though09:31
jodhdholbach: sounds like you forgot to flash the kexec kernel (step 25).09:32
dholbachweird - let me retry09:32
jodhdholbach: you can go back and do that now if you boot into the bootloader, then into recovery and select MultiROM.09:32
dholbachlet me try09:33
dholbachjodh, that made it work - perfect09:56
jodhdholbach: great! :)09:56
dholbachogra_, looks like the background is still corrupted during oem-config - also onboard was hidden by the wifi dialog, so I couldn't enter anything in there10:00
dholbachhum, I can't enter anything at all?10:01
ogra_dholbach, both known issues, i wonder if we should switch back to metacity10:01
ogra_a reboot fixes the input issue10:01
dholbachdo we have bug reports for both?10:01
ogra_i think so10:01
dholbachcan't find either of them10:04
ogra_bug 109305010:05
ubot2Launchpad bug 1093050 in ubuntu-nexus7 "OnBoard doesn't work on text boxes during initial setup" [Medium,Incomplete] https://launchpad.net/bugs/109305010:05
ogra_is the input one10:05
dholbachah yes, I must have overlooked that one10:05
ogra_bug 1080437 is one incarnation of the other issue10:05

dholbachah ok, I was just looking at https://bugs.launchpad.net/ubuntu-nexus7 nevermind10:06
ogra_or it could be bug  108126010:07
ubot2Launchpad bug 1081260 in ubiquity (Ubuntu) "/usr/lib/ubiquty/wallpaper crashes after boot of livecd" [Undecided,Confirmed] https://launchpad.net/bugs/108126010:07
ogra_not sure about that one, but it is cosmetic anyway10:07
ogra_the input one is worse10:07
ogra_jodh, be very careful about the dual boot images, afaik the userspace has some very heavy hacks, i'm not sure we can accept bugs from such an install10:08
xnoxI managed to get a wallpaper to work - instead of wallpaper use gnome-settings-daemon to paint the wallpaper, which doesn't help derivatives =(10:11
ogra_jodh, in fact i would prefer if we would not have any instructions on the wiki that make them look official and just have the XDA link instead so people grok it is some modified third party image10:14
ogra_xnox, well the input stuff is more worrying than shiny wallpapers :)10:16
ogra_(which we could just call modern art :P )10:16
jodhogra_: feel free to remove them if you wish. I appreciate there are risks, but I thought I'd share as imho it might encourage more to explore Ubuntu on the Nexus if they could keep the existing image.10:19
dholbachyes, we had a number of requests already10:19
dholbachwhat kind of "heavy hacks" were you referring to?10:19
jodhogra_: added to which, the existing instructions on dual-booting that I'd found on the web were confusing at best ;)10:19
jodhogra_: just a thought - if we keep the instructions, is there any way we could have apport detect that the Ubuntu image was booted via kexec and thus flag any bugs raised as "potentially tainted" (particularly useful for kernel bugs I guess).10:21
ogra_dholbach, look at the xda thread10:24
ogra_i havent inspected them10:24
ogra_until someone has i wouldnt recommend that image on the official install instructions10:24
reiseihi, all! Can I access the Nexus 7 accelerometer from Ubuntu? I need to get the values,14:34
Tassadarreisei: take a look at http://bazaar.launchpad.net/~jani/+junk/nexus/view/head:/nexus.go14:36
Tassadaraccelerometer is used in there to rotate the screen14:37
reiseiTassadar: but I need just the values :)14:38
Tassadarthat's why I said take a look, there is the path to accelerometr data in there14:38
Tassadarthis looks like it's folder: /sys/bus/iio/devices/iio:device0/14:39
=== cmagina_away is now known as cmagina
ogra_Tassadar, long outdated14:40
ogra_the images already have accel support14:40
Tassadarwell yeah, I just wanted to show him how to access the data, and it is pretty easy to see in that code14:40
ogra_reisei, make sure to have the latest ubuntu-defaults-nexus7 package installed, it ships accelerometer support14:41
ogra_in /usr/bin/acceld is the very simple shellscript that reads the values14:41
Tassadaroh, okay14:41
ogra_i'll add something similar for the ambient sensore the next days14:42
ogra_*sensor14:42
reiseiogra_: thanks!14:52
reiseiTassadar: thanks too!14:52
plarsogra_: hi, around?16:17
plarsogra_: we talked last week about having a fully installed image for n7, is that available now?16:17
ogra_plars, sorry, i'm a bit behind but working on it16:17
plarsogra_: no worries, any ETA?16:18
ogra_but you wouldnt have any fun with it anyway until we have images again ...16:18
ogra_seems the livefs builder park is moving or so, the last three image build attempts failed and #is couldnt give me an ETA16:19
plarsogra_: ah, I saw there is no image since 20th, but wasn't sure what was wrong16:19
ogra_plars, i plan to have the code ready and uploaded tomorrow during my day, but you will need the stuff built into the image to use it16:19
plarsogra_: ok, sounds good16:20
ogra_with luck they are back again tomorrow, i'll make sure you get an image with the bits inside once they are16:20
jragonHi16:21

ogra_achiang, bug 1103000, do you remember why we dropped that patch ? i forgot why, i just remember many things were broken when we tried16:27
ubot2Launchpad bug 1103000 in ubuntu-nexus7 "Need to charge from USB hub with power connector" [Undecided,New] https://launchpad.net/bugs/110300016:27
achiangogra_: hm, i think it caused hangs16:28
achiangogra_: like it broke the rest of USB16:28
achiangogra_: but janimo would know for sure16:29
ogra_oh, right, i remember now, yeah, it broke the whole USB stack16:29
ppisatihow do i tell flash-kernel to install my $dtb?16:30
ogra_ppisati, i doubt it has any DTB support at all yet16:30
ppisatiah16:30
ogra_apart from kernels where you cat'ed the dtd at the end16:30
* ppisati wonders again why we updated flash-kernel...16:31
ppisatiogra_: attached dtb is not an option for multiplatform16:31
ogra_ppisati, indeed16:32
ogra_ppisati, file a whishlist bug ... some code how you would do it manually would also help16:32
ogra_i'll try to get to it16:32
ppisatiogra_: i'll do once i push my fist multiplatform kernel (probably tonight or tomorrow)16:33
ogra_k, thx16:33
ogra_ppisati, and we updated because the former version was even more painful16:33
ppisatiogra_: the previous version had more stuff hardcoded, but it had DTB support16:34
ppisatiogra_: i just decided to update my im6x to latest flash-kernel to try it out16:34
ppisatiogra_: and it was a bad decision :)16:34
ogra_i could have told you :P16:34
ppisatianyhow16:35
ppisatiit i like the /usr/share/flash-kernel/db/16:36
ppisatis/it//16:36
ppisati*/usr/share/flash-kernel/db/ thing16:37
ogra_yeah, thats the biggest benefit the upgrade brought us16:37

Tassadarogra_: should I add ubuntu-nexus7 as affected project to bug 1089038? It is relevant mostly to nexus 7, and now it is just sitting among all other bugs in initramfs-tools package16:47
ubot2Launchpad bug 1089038 in initramfs-tools (Ubuntu) "[PATCH] Add support for booting from subdirectory in root" [Undecided,Confirmed] https://launchpad.net/bugs/108903816:47
ogra_well, its a pretty generic initramfs feature, i dont thinnk its nexus7 related16:48
Tassadarokay, I just felt like I should try to push things a bit from time to time16:51
ogra_well, the review team is subscribed, no need for making noise16:52
ogra_it will be in the sponsoring/reviewers queue16:52
ogra_though your chances are likely higher to get it in if you send it to debian, it adds additional delta to debians initramfs-tools16:53
ogra_which ubuntu will have to maintain16:54
TassadarI've sent it to ubuntu because I use it in my multi-boot tool, but it also needs the loop option (mounts image as root), which is only in ubuntu16:54
ogra_yes, still, its a burden ubuntu would have to carry16:55
ogra_having it in debian will get it us for free16:56
Tassadarmaybe I could send both to debian....16:56
ogra_right, that surely makes things easier on the ubuntu side16:57
