xnoxogra_: ogra-cb_ : raring-desktop-armhf+omap4.img is 22MB small. Some how I have little faith in it...00:41
ming_leilooks it is very slow to install ubuntu on nexus 7 in China02:38
ming_leicould I download the images and then update them manually?02:38
mfischming_lei: what part of the image do you want to update?  the latest installer only has 1 fix that would require a new install03:01
ming_leimfisch, it is the 1st install for me03:03
ming_leimfisch, looks rootfs.img is very large03:03
mfischming_lei: ah ok03:04
mfischming_lei: yes it's quite large03:04
mfischming_lei: let me get you a URL03:04
ming_leimfisch, I am wondering why it is not transfered by compressed file03:04
mfischming_lei: a .img file is compressed03:04
mfischming_lei: http://hwe.ubuntu.com/uds-r/nexus7/03:04
ming_leimfisch, ok, thanks03:05
ming_leimfisch, could you let me know how I can update the image manually?03:05
mfischming_lei: put the files into ~/Downloads/UbuntuNexus703:05
mfischI don't know what you mean by manually, sorry03:05
mfischDo you mean update an installed image or install a new image?03:05
ming_leiI mean how I can update the downloaded image to nexus 703:06
ming_leistill use the original installer?03:06
mfischming_lei: yes03:06
mfischming_lei: if you put the files in the right place it will say "Do you want to use the images you already downloaded?"03:06
mfischor something similar03:07
ming_leimfisch,  got it, thanks for your help03:07
mfischming_lei: I think you also need to download the "Usage Notice" file and put it in the same folder03:08
ming_leimfisch, ok,  btw, looks zenity always consume 100% cpu,03:11
mfischming_lei: yep, I saw the bug03:11
mfischand I confirmed it03:11
mfischming_lei: it makes my laptop fan run pretty wild03:11
ming_leimfisch, same with me, so I can't afford with long time update03:12
mfischming_lei: it will be much faster once you've downloaded it03:12
ming_leimfisch, yeah, that is just what I want, thank you03:12
mfischming_lei: once the files are copied it will take 10 mins or so for the tablet to unpack and lay-down the filesystem03:12
ming_leimfisch, another question, could the 8G image work well on 16G tablet?03:14
mfischming_lei: yes, it will work fine, but you will have some lost space03:15
mfischming_lei: the image is only 30-40MB larger for a 16G tablet03:15
ming_leimfisch, but looks installer doesn't support 16G image for me03:16
mfischwhat is it doing?03:17
=== _Lucretia__ is now known as _Lucretia_
ming_leimfisch, remember that it can't continue if 16G is chosen03:39
ming_leimfisch,  I am downloading the 16G image03:40
ming_leimfisch, once it is ready, first I will try 16G again03:40
ming_leimfisch, install successfully with 16G image04:46
mfischming_lei: great04:46
ming_leimfisch, but don't know how to use it04:46
ming_leimfisch, looks left click doesn't work04:46
mfischming_lei: please read all the known issues before filing any bugs04:47
ming_leimfisch, I know04:47
ming_leimfisch, so could you introduce me some usage tricks?04:47
mfischthe biggest issue is that sometimes the left click (button1) gets stuck down04:48
mfischming_lei: what do you plan on doing with the device?04:50
ming_leimfisch, I want to test some basic function, such as, terminal operation, camera function, ....04:52
mfischcamera does not work04:52

brendandxranby, oh yes. and also onboard and the keyring prompt appear. but no unity09:19
brendandxranby, i can see the little onboard overlay icon09:19
brendandxranby, worth noting that i made the tegra config change mentioned in ubuntu-devel. after that i changed it back and it still doesn't come up though09:20
xranbybrendand: do you recall if you did any software update before the reboot?09:20

ogra-cbrsalveti, any idea how i can easily find out what these missing bits are ?14:25
ogra-cbaccording to the xorg log and es2_info all should be fine now, running es2gears i get diagonal stripes on the upper half of the screen now though14:26
ogra-cband while i forced compiz to not use sw rendering, it still feels very slow14:26

rsalvetiogra-cb: are you using the same x11 driver and kernel from chrome-os?14:32
rsalvetiI suppose the libs are the same14:32
rsalveticheck with glmark2-es2 as well14:32
ogra-cbi use the armsoc driver that is supposed to work with mali 60414:32
ogra-cbglmark as well as es2gears run perfect in openbox14:32
rsalvetibut is it the same driver as used by chrome-os?14:33
rsalvetithat's weird14:33
ogra-cbi guess that compiz does some auto-fallback for some functions or so14:33
rsalvetior it's just slow :-)14:33
ogra-cbso i get it mixed with SW rendering14:33
ogra-cbwell, but why do i get the disgonal stripes etc14:33
ogra-cball gles apps runs just fine in openbox, just not under compiz14:34
ogra-cbso something seems to get in the way14:34
rsalveticompiz is the compositor, so it'll mess  up with your desktop14:34
ogra-cbsure14:34
ogra-cbit doesnt on omap or nvidia though14:34
rsalvetiit's the final one to render the composed texture, and that might be the issue14:34
rsalvetimight be because it's trying the sw fallback with this driver14:35
ogra-cbwell, you can force it not to by exporting LIBGL_ALWAYS_SOFTWARE=014:36
ogra-cbwhich i do atm14:36
ogra-cbelse it automatically falls back to llvmpipe14:37

rsalvetiI know :-)14:40
rsalvetiogra-cb: do you know if that's the x11 driver used by chrome-os?14:40
rsalvetiI'd be surprised14:40
rsalvetithis is not for 'production' :-)14:40
ogra-cbnot sure what source the cros driver uses14:41
ogra-cbthe binary is for abi12 so i cant use it14:41
ogra-cb(we skipped 12 completely in ubuntu)14:41
ogra-cbpresscise is 11 and quantal+raring are 1314:42
ogra-cbi dont get why es2_info works flawless though14:43
ogra-cbhttp://paste.ubuntu.com/1355604/ has my xorg.conf btw14:44
ogra-cbif i leave glx enabled in there it tries to load /usr/lib/arm-linux-gnueabihf/dri/armsoc_dri.so which i dont have14:46
ogra-cbi dont really get why it searches for that at all14:47
rsalvetihm, guess you only need:14:47
rsalveti    Identifier "DefaultDevice"14:47
rsalvetiDriver          "armsoc"14:47
rsalvetiI think even for panda it tries the glx mode when loading the x11 driver14:48
rsalvetiwhich is fine if you don't have14:48
xnoxogra-cb: sent f2fs pull&build request to the kernel team to bake a tasty kernel for: i386, amd64 and arm's (ac100, panda, nexus7)14:49

ogra-cbbut others (mfisch, cwayne) saw corruption using that option18:07
ogra-cbwhich made us choose to not use it18:07
kulveI would guess that it flash the first 256M in the start of the partition and then the latter 256M again in the start of the partition and thus it will be a mess. Or something like that18:08

KC9SJQHowdy all, I'm having a bit of trouble.21:44
KC9SJQI want a preinstalled ubuntu image for my panda, like I did for ubuntu 11.04 and 12.04, however, they don't seem to exist for the most recent ubuntu.21:44
KC9SJQAre these delayed? Are they not being made anymore?21:45
infinityKC9SJQ: The latter.  We stopped doing preinstalled images, as the user experience was, frankly, pretty lousy.21:45
infinityKC9SJQ: (The installation experience was nice, but then you were stuck with a system running from SD, so... Not ideal)21:45
KC9SJQThen, is there a tutorial on how to install the proper image on a panda? AFAIK, they must boot from the SD card.21:46
infinityYes, we still boot from SD, but expect you to be installing to a USB storage device (a hard drive, ideally)21:46
infinityNo tutorial needed, really.  Plug in USB storage, write install media to SD card, boot.21:47
KC9SJQAnd when done, I just leave the SD out of the machine?21:47
infinityNo, you'll need to keep the SD in, as that's where the bootloader lives.21:47
KC9SJQah, okay21:48
KC9SJQAnd the installer sets up the mapping properly?21:49
infinityYep.21:58
* xnox did update omap4 install wiki with bullet points22:14
KC9SJQxnox: which wiki exactly?22:29
xnoxhttps://wiki.ubuntu.com/ARM/OmapDesktopInstall22:29
xnoxthe installation instructions for arm22:30
xnoxit's linked from https://wiki.ubuntu.com/ARM/OMAP22:30
xnoxwhich all other websites link to. as that is the "arm" landing page.22:30
xnoxit's not great but good enough.22:30
xnoxalso 12.10 release notes explain the arm situation.22:30
KC9SJQThanks for the heads up, I appreciate it.22:35
KC9SJQDoes anyone know if I can set the wifi adaptor in the panda into master or ap mode?22:40
KC9SJQOr more importantly, are there instructions on how to set it up?22:41
infinityNever tried using it as an AP, but if the driver supports it, installing hostapd would likely make it Just Work.22:43
KC9SJQNow, that is the part that seems to confuse me. I attempted the isntructions here  (https://help.ubuntu.com/community/Router) last time, but apparently hostapd replaces editing the internal /etc/network/interfaces22:44
infinityKC9SJQ: The new world order of hostapd/ifupdown integration is generally a lot less fiddly.22:47
infinityKC9SJQ: Here's a config (minus a bunch of local stuff that's not relevant) from my precise router: http://paste.ubuntu.com/1356710/22:47
infinityKC9SJQ: The key being the "hostapd /path/to/conf" bit that replaces having to fiddle with wireless-* stuff in interfaces only to see hostapd redo it differently half a second later. :P22:48
KC9SJQWhat is in /etc/hostapd/hostapd.conf? Is that mostly the default?22:49
infinityIt's basically the default, modulo setting up a password, setting interface=wlan0 and, in my case, bridge=br022:50
infinityThe last bit likely less relevant on a Panda, where you're probably not setting up a bridge.22:50
infinity(As such, your /etc/network/interface bits would be under "wlan0" instead of "br0" too)22:51
infinity... and obviously wouldn't have the bridge_* bits.22:52
KC9SJQYeah, I won't be bridging, only serving.22:54
KC9SJQAllright, I'm backing up my data drive now. Tomorrow that should be done, and I'll install ubuntu to the hd.23:00
