slangaseklfaraone: opting out of the HWE stack == use 12.04.1 (or 12.04.0) media for install03:24
geofftslangasek: these are nontechnical end users, they click the thing that says "Ubuntu", we don't get to tell them what to install until after they installed :-( 03:27
geofftwe put up a warning on our home page, but people will still go and install Ubuntu and then say "oh hm I want AFS" later 03:28
geofftand they get the default obvious CD image from ubuntu.com 03:28
geofft... actually _I_ can't figure out how to get 12.04.x for x<3 from http://www.ubuntu.com/download/desktop 03:29
geofftalternative downloads | past releases takes me to releases.ubuntu.com, and that just give sme 12.04.3 03:30
infinitygeofft: Bottom of the page, "Take a look at a full list of our previous versions and alternative downloads".  And agreed, that's not even remotely intuitive.03:30
geofftinfinity: I don't think it's there! 03:31
infinitygeofft: It is, bottom of THAT page, "past releases..."03:31
geofftkeep clicking. it's not there. 03:32
infinityWhich... Then goes to releases.u.c, which remains unhelpful, you're right.03:32
infinity*sigh*03:32
geofftOh! I go to "unsupported Ubuntu images". 03:32
infinityFor the record, it's on old-releases.03:32
geofftThat gets me 12.04.0 for ... powerpc, nevermind 03:32
infinityThe link right under the one you clicked. :P03:33
infinityAnyhow, we need to make this experience far less crap.  I have a todo item for that.03:33
geofftYeah, I am going to politely disagree with the claim that it's possible for an end user to figure this out. We're in the position of downgrading kernels post-install 03:33
geofftOr, really, just having people install OpenAFS from an alternative source, which is what we're doing now. (I think our installer shell script sets up the PPA) 03:34
infinityWell, it's *possible*, but I'll agree that it's not *plausible* that most will figure this out.03:34
geofftAnd yes, afaik (which is not very rigorously, to be fair), our users tend not to have hardware that requires the HWE stack 03:35

pkernHey. https://help.ubuntu.com/community/Kernel/Compile#Modify_the_source_for_your_needs seems a bit outdated. If I have a linux-lts-raring apt-get source'd, how would I modify the kernel config? Somehow all files I find have a splitconfig.pl header.13:40
=== shengyao is now known as shengyao_afk
apwpkern, add the option you want to change to the apporpriate leaf file in the config, and then run 'fakeroot debian/rules updateconfigs'14:58
apwwhich will sort out making the configs consistant14:58

ollihey, I am looking for a pointer how to catch a "swivel" event on a Dell XPS 12 (where the screen flips horizontally and turns it into a "tablet")16:51
olliI have tried to listen to /dev/input/event* and also looked in /proc/bus/input/devices for pointers16:51
olliis there another common place to look at?16:52
sforsheeolli: I'd expect dell-wmi to be receiving the events. If it's an event dell-wmi understands it will probably show up on the input device it creates.16:52
sforsheeolli: otherwise it would need to be taught about the event16:52
sforsheeolli: but you might also try running acpi_listen and see if it spits out anything16:53
ollisforshee, ah, forgot to mention that acpi_listen didn't produce anything16:54
ollisforshee, is it a valid approach to just cat /dev/input/event* and see if something happens or would cat miss something?16:54
ollievent* = a single event dev, e.g. event1016:54
sforsheeolli: that might not work. X grabs the input devices so that nothing else sees the events.16:55
sforsheeolli: what I usually do is install input-utils, swtich to a vt, use lsinput to identify the device I'm interested in, then use input-events to watch the events from that device16:55
ollisforshee, awesome, thanks, I will try that16:56
sforsheeolli: the other thing I'd suggest is seeing if anything appears in dmesg when you rotate the screen16:58
jsalisbury##16:59
jsalisbury## Meeting starting now16:59
jsalisbury##17:00
sforsheeolli: one of the relevant messages is debug-level and won't appear in dmesg by default. Let me dig up the command that will enable it.17:00
sforsheeolli: echo "module dell-wmi +p" | sudo tee /sys/kernel/debug/dynamic_debug/control17:01
sforsheethat should do it17:01
ollisforshee, that doesn't seem to trigger any additional messages, and using input-events on the dell-wmi device on a vt doesn't show anything either17:12
olliis this the case you mentioned earlier where dell-wmi needs to be taught about it17:13
sforsheeolli: no, if it received events that it didn't know what to do with you should have seen something in dmesg17:13
ollihm17:13
sforsheeI'm not coming up with anywhere else to look off the top of my head17:14
ollisforshee, then there is still a big chance of pebkac on my side, will keep trying17:14
ollisforshee, thx for now, might bug you later17:14
sforsheeolli: are you absolutely sure it's generating an event? I.e. is there some observable behavior in Windows which leads you to that conclusion?17:15

ollisforshee, http://www.youtube.com/watch?v=nU9Pa3nF6y4 at 0:50 you can see windows switching modes when swiveling, I of course nuked my win partition, but will install to verify17:18

pkernapw: So debian.master and it will do the appropriate change to debian.raring? Or are LTS backports even more special?21:18
apwpkern, lts-backports are even more special21:46
pkernapw: Ok, so I guess I'll try to modify debian.raring tomorrow. I need DYNAMIC_DEBUG for some e1000e suspend issue. |:23:26
