ppisatitseliot: yesterday i reinstalled my P/amd64 desktop and found two oddities with the ATI/AMD driver09:42
ppisatitseliot: first, jockey proposed me two differents drivers (one was marked as - post release update or something like that, the other had no particular notes)09:43
ppisatitseliot: so first i tried the "post release updates", but it failed to compile/install09:43
ppisatitseliot: while the "normal one" succeded09:44
ppisatitseliot: second oddities - to properly handle a dual screen setup i had to manually tweak my X conf file09:44
ppisatitseliot: and add a Display subsection09:44
ppisatitseliot: with a virtual option equal to the sum of the two screens resolution09:45
tseliotppisati: there isn't much I can do without a log about the module which failed to build09:58
ppisatitseliot: i think i've it09:59
ppisatitseliot: or i can try to reinstall it09:59
tseliotppisati: the second oddity is really about their implementation of Randr in the driver which doesn't allow front buffer reallocation09:59
tseliotppisati: also, what kernel are you using?10:00
ppisati3.2.0-23-generic #36-Ubuntu10:00
ppisatix86_6410:00
ppisatibrand new P/amd64 desktop installation10:00
ppisatiok, it failed again10:01
tseliotplease collect the log10:01
ppisatitseliot: http://people.canonical.com/~ppisati/jockey.log10:02
ppisatitseliot: does it make any sense to you?10:04
tseliotppisati: so, the driver built successfully but somehow it couldn't be enabled. What's the output of update-alternatives --display x86_64-linux-gnu_gl_conf ?10:12
ppisatitseliot: http://people.canonical.com/~ppisati/upd-alt.x86_64-linux-gnu_gl_conf10:25
tseliotppisati: it looks fine. It could be a bug in Jockey10:29
ppisatitseliot: can i install it manually?10:30
tseliotppisati: it seems to be already installed correctly10:31
ppisatitseliot: ah10:31
ppisatitseliot: http://paste.ubuntu.com/1124965/10:31
ppisatibrb10:38
tseliotppisati: yes, it looks good. You might want to reboot now10:41
ppisatitseliot: weird10:54
* ppisati -> reboot10:54
ppisatitseliot: ok, did two reboots just to be sure11:01
tseliotppisati: and?11:01
ppisatitseliot: and the second display (the right one) is garbled11:01
ppisatitseliot: if i mirro the display, and then go back to this config, it fixes it11:02
tseliotppisati: are talking about indipendent heads?11:02
tseliot*are we11:02
ppisatitseliot: but after every reboot the screen is "full of crap"11:02
ppisatitseliot: yep11:02
ppisatitseliot: with the previius driver it was ok11:02
ppisatitseliot: i mean, before the reboot11:02
apwtseliot, i assume you are aware of the nvidia exploit ?11:03
tseliotppisati: what version works for you and what doesn't?11:03
tseliotapw: yes but there are some many vulnerabilities you'd be surprised...11:03
ppisatitseliot: the version that doesn't is the one that had problem installing via jockey11:03
ppisatitseliot: let me get the rev11:04
apwtseliot, actually i suspect i wouldn't be supprised, just supprised this is the first i have heard of11:04
ppisatitseliot: 2:8.960-0ubuntu111:04
* ppisati reboots again11:06
ppisatitseliot: still crap... ahhhhhh...11:09
tseliotppisati: so you get the corruption with both releases11:12
ppisatitseliot: yes11:13
ppisatitseliot: previously was http://paste.ubuntu.com/1124965/11:15
ppisatitseliot: now i'm like this http://paste.ubuntu.com/1125017/11:15
ppisatitseliot: still garbled right head11:15
tseliotppisati: please file a bug report and I'll forward it to AMD11:15
* ppisati considers going with the open source driver11:15
tseliotit's the same driver, BTW11:15
ppisatitseliot: one says "fglrx" the otehr says "fglrx-updates"11:16
ppisatitseliot: and according to jockeys are different11:16
ppisatitseliot: anyway, i'll file a bug11:16
tseliotppisati: they will be different as soon as I update fglrx-updates with a newer release ;)11:18
ppisatitseliot: my life sucks...11:22
tseliotppisati: you can uninstall the current driver, download the latest driver from AMD's website and run the installer with "--buildpkg Ubuntu/precise" and install the deb packages that it generates11:23
tseliotapw: heh, they were private reports ;)11:24
* henrix -> out for lunch11:35
ppisatitseliot: i can live with that for now11:52
ppisatitseliot: when do you plan to update it?11:52
tseliotppisati: they have to accept my SRU for the LTS first, then I can think of updating the driver. You should probably try AMD's latest driver to see if at least it fixes the issue11:56
ppisatitseliot: want to do some work this afternoon, i'll try this evening11:57
ppisatitseliot: btw, is there a changelog somewhere?11:57
tseliotppisati: no, I don't think they have such things ;)11:58
* ppisati assumes a fetal position and cries...11:59
tseliotat least not publicly available11:59
tseliot:D11:59
ppisatitseliot: and is there any mention of screen corruption in that non-existant changelog?12:00
tseliotppisati: I don't think so, but you never know ;)12:02
ppisatitseliot: ok :)12:02
ppisatiah, and now i see why weather-indicator doesn't work12:24

* infinity whispers "rubber trees" in smb's ear.12:52
smbyellow! :-P12:52
infinityYellow?  I'm not sure I like where this is going.12:52
infinityYou're a disturbing man.12:53
smbinfinity, Hey, you started. ;)12:53
infinityI beg to differ.12:53
infinity06:39 < smb> maybe we nee more rubber trees12:53
infinity^-- Evidence.12:53
smbinfinity, I just meant real normal ones instead of trampolines. Everything else was your imagination.12:54
infinitysmb: Real... Normal... Rubber... Trees?  Kay.12:55
infinitysmb: We'll get you one of those "normal" black ski masks with zippers, too.  You know, for skiing.  Like a normal person.  Who likes zippers.12:55
smbinfinity, I seriously doubt your skiing experience...12:57
ogra_geez... whats going on here !12:57
smbinfinity, Next thing comes the table tennis ball on a string, for people who tend to loose them12:57
* ogra_ wonders if there is a beer shortage or so ...12:58
smbogra_, Rather an over supply on temperature outside...12:59
ogra_heh12:59
smbBut those tend to go together12:59
ogra_yeah, here too (boston)12:59
ogra_rather tropical weather12:59
smbAt least buildings there tend to have ac12:59
rtgapw, kmod still produces map files ?13:03
smbinfinity, Just to "cool" down the discussion, I was actually thinking of this: http://www.youtube.com/watch?v=1-_-QxerYno13:04
apwrtg, kmod has no code to do so13:07
apwthe older map files, it still makes binary accelerator files13:07
infinitysmb: Yeah, Monkey Island gets me going too.13:13
rtgapw, seems to be working. I've installed a new kernel and nothing has caught on fire13:16
apwrtg, nice ... i had it on my box through 3 updates without remembering i'd install it13:18
* cooloney just realize overlayfs is not in mainline yet13:21
cooloneyapw: will overlayfs be merged into mainline recently?13:25
apwcooloney, its not making much progress13:27
cooloneyapw: ha, got it. just sent an email about the lxc issue with overlayfs to maintainer, but i also copied it to lkml.13:28
apwcooloney, can you forward me a copy pls13:30
cooloneyapw: oh, i think i copied it to our public mail list13:31

ppisatiuhm is back15:05
argesppisati, apw : mumble is crashing when i load it.. is there a bug associated with this?15:10
apwarges, mine seems to have settled, i think it was a server side issue for us15:11
smbThough crashing is probably not the epected reaction15:11
argeswell even moved my .conf file to see if it was that. time to file a bug15:15
argesapw, ah its because i had selected jack audio as the output, if I select another output it works fine15:22
apwarges, la la la jack is wonderful15:26
argesit acutally looks like a pulseaudio bug 15:26
argesat least that's where the crash is in the backtrace15:27

shadeslayerhi20:01
shadeslayerI'm trying to use make-kpkg to compile my own kernel with a custom config20:02
shadeslayerbut I get this 20:02
shadeslayerdpkg-gencontrol: error: illegal package name 'linux-image-3.5.0-powersave-ARCH': character 'A' not allowed20:02
shadeslayerI've looked at the wiki and the documentation there seems to be a bit .. convoluted, and make-kpkg seems a bit easier20:02
apwshadeslayer, no idea where that -powersave- is coming from ...20:09
shadeslayerapw: that's me20:10
shadeslayerfakeroot make-kpkg --append-to-version="-powersave" kernel_image --initrd binary -j6                                                                         20:10
shadeslayera bit of clarification, the primary reason I'm compiling my own kernel is because I want to get the I915 module compiled into the kernel20:10
shadeslayerand not as a module20:10
shadeslayerthat would allow me to switch off my discrete graphics card20:11
shadeslayer( currently I can't because if I switch off my discrete card via grub the kernel can't find *any* graphics card and the screen goes black )20:11
apwhow are you turning it off via grub when it fails20:15
shadeslayeroh, grub boots fine, then you can use 'out' to send bits over the wire20:19
shadeslayerand turn off the graphics card 20:19
apwso why would building in 915 help ?20:22
shadeslayerbecause the I915 code initializes the intel graphics card?20:22
shadeslayerDid I mention I have 2 graphic cards?20:23
apwthe same code is run whether its a module or builtin ?20:23
shadeslayer00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)20:23
shadeslayer01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Seymour XT/PRO [Radeon HD 7400M Series]20:23
shadeslayerapw: afaik you need to build in the code so that the card gets initialized and you have one working graphics card20:24
apwthat to me doesn't make sense as builtin or not the driver will get loaded if you have the device in your PCI listing20:24
shadeslayerI've already tried switching off the graphics without the module built in and the screen doesn't show anything20:25
* apw suspects it won't make a differnece20:25
shadeslayersec20:26
* shadeslayer pulls up docs20:26
shadeslayeroh .. maybe this is it20:28
shadeslayer"If you have blackscreen on boot, it may be because you've built both Framebuffer Console support and the i915 driver (with KMS enabled) as modules. The blackscreen is a result of the i945 driver probing for displays before the fbcon module is loaded. As it can't find any console display(because the fbcon driver isn't loaded yet) it simply turns it off."20:28
apwthat implies you want fbcon builtin and i915 not20:29
shadeslayertrue, I've just found that20:29
shadeslayeror 20:29
shadeslayerhttp://en.gentoo-wiki.com/wiki/Intel_GMA20:29
shadeslayerI just add modules="fbcon" to /etc/conf.d/modules as suggested by that wiki20:30
apwshadeslayer, i think fbcon is builtin in ubuntu20:31
shadeslayercan you tell me the key for fbcon?20:32
apwshadeslayer, indeed its builtin20:32
apwkey?20:32
apwgrep fbcon /lib/modules/3.5.0-6-generic/modules.builtin20:33
apwkernel/drivers/video/console/fbcon.ko20:33
shadeslayeroh .. I was looking at /boot/config-3.5.0-6-generic20:33
shadeslayerinterestingly : CONFIG_DRM_I915_KMS=y20:34
shadeslayerso the I915 driver is built as a module20:34
shadeslayerbut KMS is built in20:34
apwno that is just a toggle, enabling kms support20:36
apwin tghe module20:36
shadeslayeroh ... I thought 'y' meant that it was built in20:36
shadeslayerand m, like in this one : CONFIG_DRM_I915=m20:36
shadeslayermeant it was a module20:36
apwdepends if it is bool or tristate20:37
apwand indeed what it i use for20:37
shadeslayeroh .. interesting ...20:37
shadeslayerapw: so according to you, it *should* work?20:39
shadeslayerwith the default config20:39
apwaccording to the limitations you are saying are required, i think you are already meeting them20:39
shadeslayerhmm ... I'll try again, and lets see what happens this time20:40
shadeslayerapw: http://dentifrice.poivron.org/laptops/macbookpro8,2/ < if you go down to the place where the article talks about GRUB menuentries, you'll see what I was talking about :)20:47
apwof course it is a macbook20:49
shadeslayerhaha :D20:49
apwdamn apple20:49
shadeslayeras a matter of fact, I have a very simple mechanism to get a ubuntu ISO boot from a USB drive in EFI mode20:50
shadeslayerbbiab, trying out the outb commands20:51
apwthe i915 driver requires a patch activating dual LVDS channels, otherwise it will show nothing but a black screen;20:51
apwfrom the doc you pasted ^^20:51
bjfjjohansen: have you had a change to look at bug 1028837 ?20:53
jjohansenbjf: do you mean 1029937?20:54
jjohansenbjf: I have started but haven't gotten very far20:55
bjfprobably20:56
bjfjjohansen: yes i do20:56
shadeslayerapw: I thought the dual LVDS channels patches were incorporated with the 3.5 kernel ....21:11
apwshadeslayer, dunno maybe21:16
* apw sleeps21:16
shadeslayerI should probably sleep as well :P21:16
shadeslayerright after I check if the patch was applied or not21:17
shadeslayerseems not21:17
shadeslayerso I'll have to compile it afterall21:17
shadeslayerbah, I was looking at the wrong patch, applying the lvds patch fails21:27
shadeslayerneed to look at the code21:27
