| bornet | Hi ubuntu-arm gurus | 08:24 |
| bornet | i'm trying to run 12.04 on my beagle xm and followed wiki install instructions... so far so good, everything installs correctly and I can boot into my fresh installed pangolin | 08:25 |
| bornet | but the performance/reactivity is not so good.. is it an expected behavior ? I have no point of comparison so it's difficult to make an idea | 08:26 |
| === hrww is now known as hrw | ||
| brendand | bornet, it won't run well on the beagle xm i imagine | 08:30 |
| bornet | thanks for feedback brendand. Did you personally try it ? | 08:33 |
| brendand | bornet, no - i've only tried on the pandaboard, which has 1GB of RAM | 08:34 |
| ogra_ | it should run fine but dont forget what you are running from ;) | 08:35 |
| brendand | bornet, it can also be slow because it is running off of the SD card | 08:35 |
| ogra_ | even the panda feels slow due to running from SD | 08:35 |
| bornet | OK it's what I feared... | 08:35 |
| bornet | i will first try with a better SD card | 08:35 |
| ogra_ | there are netinstall images that allow you to install to USB HDD | 08:36 |
| brendand | bornet, it doesn't really depend on the quality of the card. flash is just slow | 08:36 |
| bornet | not top class SD card at the moment... what I had under hand... | 08:36 |
| ogra_ | while USB isnt great either (limited to 24MB/s) its still a big improvement over SD card | 08:36 |
| brendand | bornet, if you have a usb media it will work better | 08:36 |
| bornet | yes i'll try with USB | 08:37 |
| twb | Of course if you add enough RAM it won't matter because the SD card will only be read from / written to at boot / halt time, right? ;-) | 08:38 |
| brendand | twb, no - the os frequently needs to access the filesystem | 08:39 |
| twb | brendand: depends how high you crank the settings in /proc | 08:39 |
| brendand | twb - and adding ram to a beagleboard is going to be an interesting trick | 08:39 |
| twb | And on the filesystem design of course | 08:39 |
| twb | But I was being flippant | 08:39 |
| ogra_ | you still need certain directories writable | 08:39 |
| twb | Sure sure | 08:40 |
| ogra_ | and indeed you need to read a lot | 08:40 |
| twb | But you can just say "hey ext4 please buffer writes for up to 24 hours" | 08:40 |
| twb | And hope you don't crash :-) | 08:40 |
| bornet | >> the os frequently needs to access the filesystem | 08:40 |
| bornet | not the OS (Linux) directly but the userspace | 08:40 |
| ogra_ | (look at the source of casper to see which dirs btw, it actually runs / completely from ram (on top of an overlayfs) | 08:40 |
| twb | It works especially well if you have more RAM than SD card capcity | 08:40 |
| twb | ogra_: well, aufs of ro rootfs + tmpfs | 08:41 |
| bornet | and Ubuntu is perhaps not the best in this case (frequent FS access) | 08:41 |
| ogra_ | twb, right | 08:41 |
| twb | Have they switched away from aufs? Or did you mean overlayfs as a generic term | 08:41 |
| ogra_ | bornet, i doubt its any worse or better than any other modern linux distro | 08:42 |
| twb | bornet: yeah, it's not Ubuntu it's gnome doing that | 08:42 |
| ogra_ | if you have the same SW^ selection you should have roughly the same amount of IO | 08:42 |
| bornet | yes for sure, we'll try some other "lightweight" WM and distro | 08:43 |
| twb | X is for wimps | 08:43 |
| bornet | any experience with XFCE ? does it perform better on panda/beagle ? | 08:43 |
| ogra_ | lubuntu-desktop is pretty nice and seems to run in under 80M when idling | 08:43 |
| bornet | thanks, i'll try this one | 08:44 |
| ogra_ | (teh default unity-2d desktop uses about 120M btw) | 08:44 |
| ogra_ | xubuntu should be somewhere between these two | 08:44 |
| bornet | never been fan of unity even for my Core i7 desktop... | 08:44 |
| bornet | OK I'll first try with lubuntu | 08:45 |
| * ogra_ likes it in 12.04 ... all former releases were still pretty buggy) | 08:45 | |
| bornet | and will give you feedback here when done :-) | 08:45 |
| twb | http://paste.debian.net/166959/ | 08:46 |
| twb | I should probably replace rsyslogd with busybox-syslogd | 08:46 |
| lilstevie | I have to say I like unity for touchscreen environments | 09:01 |
| lilstevie | and yeah, unity is much more stable in 12.04 like ogra said | 09:02 |
| twb | I struggle to achieve anything with touchscreens. At least, anything that requires more input than "follow link" and "scroll down" | 09:02 |
| twb | My fingers must simply be too fat | 09:02 |

| lilstevie | ogra_: really? I am finding that it is stable | 11:46 |
| ogra_ | lilstevie, what kernel version do you use ? | 11:49 |
| ogra_ | might be that the ac100 precise kernel is to old or misses patches | 11:50 |
| lilstevie | 3.1.10 | 11:51 |

| narcotic | Ih everyone ! I'm wondering if ubuntu ARM would work on a Acer tab a510 (tegra 3 tablet) | 12:56 |
| ogra_ | if someone ported kernel and bootloader ... | 12:57 |
| ogra_ | userspace (rootfs) should just run | 12:57 |
| ppisati | if they would release their kernel bits... | 12:57 |
| lilstevie | narcotic: well yeah, as long as you can replace the kernel | 12:59 |
| lilstevie | narcotic: I am running ubuntu on my transformer prime (tegra 3) | 12:59 |
| narcotic | and does it work well with touch ? | 12:59 |
| lilstevie | well is a subjective term | 12:59 |
| lilstevie | it works as bout as well as you could hope | 13:00 |
| lilstevie | the transformer prime has a lot of "noise" when it comes to the touchscreen | 13:00 |
| narcotic | ok, sounds nice ! I don't have my tablet yet but when I will have it, I will try installing it. | 13:02 |
| lilstevie | it will require some work | 13:02 |
| narcotic | that's what I'm a bit scared of... I'm quite new to all the ubuntu stuff, I don't even know what kernel means so... | 13:03 |
| narcotic | (sorry if my english is not good :p ) | 13:06 |
| ogra_ | good enough to understand you :) | 13:06 |
| ogra_ | (at least for this german here :) ) | 13:06 |
| narcotic | ok :) | 13:08 |
| ogra_ | i assume its you who just mailed me about the same device ? | 13:08 |
| narcotic | yes | 13:09 |
| ogra_ | k | 13:09 |
| narcotic | Then i tought about the IRC channel... | 13:11 |
| lilstevie | getting everything working takes a bit of work, but just getting it to the point of booting isnt too difficult | 13:11 |
| ogra_ | yup. thats usually the quicker way of getting answers | 13:11 |
| narcotic | and apparently, the bootloader of the acer tab a510 isn't locked like the prime (I think) | 13:19 |
| narcotic | lilstevie : do you still have android on the prime (dual boot) or not ? | 13:20 |
| lilstevie | no | 13:21 |
| narcotic | do you think it would be possible ? | 13:21 |

| timholum | hello, I installed ubuntu on a beaglebone using http://elinux.org/BeagleBoardUbuntu tutorial, I now need to compile a kernel driver, and I can not find the kernel source package, I did 'apt-cache search linux-headers-$(uname -r)' and that comes up blank, any Ideas as to where to find the kernel source package for my system? | 21:01 |
| timholum | this is the output of uname -a, Linux omap 3.2.0-psp6 #1 Thu Mar 22 04:30:37 UTC 2012 armv7l armv7l armv7l GNU/Linux | 21:01 |
| rcn-ee | timholum, it's external.. | 21:09 |
| rcn-ee | it's hosted as a script here: https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.2 | 21:09 |
| rcn-ee | fingers crossed, it'll be mainline 3.5/3.6 | 21:10 |
| mythos | hmm... does someone know, where i could get a flashbinary for the arm-architecture? | 22:17 |
| mythos | android-one does not work, because of too many android-specific libraries | 22:18 |
| XorA | you stuck with gnash or lightspark | 22:19 |
| rcn-ee | if your on omap, ti has one you can register/download.. haven't tried it but i know it's there.. | 22:21 |
| mythos | how do i check if it is an omap? | 22:22 |
| rcn-ee | what processor are you running on? | 22:22 |
| * XorA sees 12.04 LTS spash on beagleXM | 22:22 | |
| rcn-ee | or even what board? | 22:23 |
| mythos | rcn-ee, http://paste.ubuntu.com/963425/ | 22:23 |
| mythos | it is an ti evalboard | 22:24 |
| rcn-ee | well, you can't tel from that paste.. | 22:24 |
| mythos | i thought so too =) | 22:24 |
| rcn-ee | if it's an ti eval board, it would fall under the omap family/subfmaily | 22:24 |
| mythos | what does omap mean? | 22:25 |
| infinity | OMAP is TI's family of ARM SoCs. | 22:25 |
| XorA | omap and whatever catalogue call theres this week :-D | 22:25 |
| rcn-ee | for us, run under the "mach-omap2" kernel. ;) | 22:25 |
| mythos | ok, it is an omap-board | 22:25 |
| infinity | OMAP3 is what one finds on the Beagleboard, and in many phones and tablets out there, OMAP4 is on the Panda, and some other shiny hardware (like the Kindle Fire), OMAP5 is their new Cortex-A15 SoC... | 22:25 |
| mythos | my board is a ti8148evm | 22:26 |
| rcn-ee | mythos, found it.. http://www.ti.com/tool/adobeflash-a8 good luck, there's an x11 bin, haven't ever tried it.. | 22:26 |
| mythos | im going to look in the specs | 22:26 |
| rcn-ee | ah, with the reorg, that is now in the 'omap buisiness unit'. ;) | 22:27 |
| mythos | omg, thank you rcn-ee =D | 22:27 |
| XorA | rcn-ee: I love that TI has been re-orging for at least 5 years now :-D | 22:29 |
| rcn-ee | XorA, when i was at the ti summit last week, for the sitara group, it's like the 3rd time this year already. ;) | 22:29 |
| XorA | kinda like put all their staff in a giant tombola and see where they fall out | 22:29 |
| * XorA feels lucky MIS is pretty stable | 22:29 | |
| rcn-ee | side note, the reason for the mess of the am335x upstream status makes perfect sense.. there's no dev in that team yet. ;) | 22:30 |
| * XorA has a login screen woo woo | 22:32 | |
| davecheney | has anyone used perf on 12.04/omap4 ? | 23:17 |
