| orated | Hello! I often see line like - 'iwlagn 0000:03:00.0: Aggregation not enabled for tid 0 because load = 1' repeating in vt during which the wireless disconnects and then connects back. dmesg | tail - http://paste.ubuntu.com/846902/ . What exactly is causing disconnection and how can I fix it? Laptop uses - Intel Advanced-N6230 (2x2 agn + Bluetooth) whereas wireless router supports all b/g/n | 07:10 |
|---|---|---|
| ohsix | dunno what "load = 1" may mean, but i think tid means transmitter id, and aggregation has to do with mimo, if you could disable that it might be more reliable | 07:12 |
| ohsix | there's also a #linux-wireless channel where you can get some direct advice | 07:12 |
| orated | What is mimo? | 07:12 |
| ohsix | multi input, multi output; basically multiple antennas | 07:13 |
| orated | Sure, I'll try that. BTW is there a way to confirm if N standard is conflicting? | 07:13 |
| ohsix | probably with sufficient knowledge, something don't have :] | 07:14 |
| orated | No, thank you. I'll try what you suggested | 07:15 |
| ohsix | most vendors had version numbers on things, maybe you can find a compatibility matrix | 07:15 |
| orated | ah, that went above my head ;) | 07:15 |
| orated | Hey ohsix, are you still there? | 10:00 |

| orated | Hello! Anyone got suggestions to dig the cause of weird troughs and peaks here- http://imagebin.org/199583 - its only causing cpu fan to rev up & down periodically ...? | 20:49 |
| orated | The first is memory readings and other is temperature based on lm-sensors | 20:52 |
| ohsix | what is the period on that graph? | 20:53 |
| ohsix | (chances are it's that graph ;]) | 20:53 |
| orated | Yes, graph with 0.5s period | 20:54 |
| orated | It is annoying to find fan to function that way even in absolute idle | 20:55 |
| ohsix | well there is perf top, latencytop and a bunch of other not-top top like tools that can give you some visibility into it | 20:57 |
| ohsix | i've got a notebook that does exactly that, except it's the bios & the video card doing it; you might be able to adjust the thermal zones so it comes on a little later and knocks off those tops | 20:59 |
| orated | What is the package name for perf top? | 21:00 |
| ohsix | linux-tools | 21:01 |
| orated | How come BIOS was? I'm trying to adjust the thermal zones.. I read that fancontrol, sensors-detect and pwmconfig can help to do so but there is nothing I could find which can give me fan rpm | 21:01 |
| orated | How would you adjust thermal zones? | 21:01 |
| ohsix | there are knobs in /sys/devices/virtual/thermal, and a .txt in the kernel tree (in Documentation/ somewhere) that describes them | 21:03 |
| orated | ' .txt in the kernel tree (in Documentation' - you mean the one listing all the linux options, like those one can pass through grub? | 21:04 |
| ohsix | http://lxr.linux.no/#linux+v3.2.6/Documentation/thermal/sysfs-api.txt | 21:04 |
| orated | Great! | 21:05 |
| orated | I'm not sure about changes to make under /sys/devices/virtual/thermal .. could you guide me on that? | 21:07 |
| orated | I see colling_device and thermal_zone there | 21:07 |

| ohsix | sforshee: can you amend the article? https://wiki.ubuntu.com/Hotkeys/Troubleshooting (README.keymap.txt has been README.keymap.txt.gz for a while) | 21:18 |
| ohsix | sforshee: wouldn't it be funny if they stopped working because g-s-d removed the bindings for enable and disable, and just have toggle? :D | 21:43 |
| ohsix | sforshee: yea if i map them to toggle instead of enable/disable they work, and a bunch of other keymaps included with the udev version on natty are broken/obsolete in the same way | 21:55 |
| jwi | ohsix: reminds me of http://lists.freedesktop.org/archives/xorg/2010-November/051727.html :) | 22:13 |
| ohsix | hey that looks like a useful reference, thanks | 22:15 |
| ohsix | similar timeframe to my frustration too | 22:15 |
| ohsix | arghh that explains why they all still exist in a udev keymap too | 22:22 |
| ohsix | bbl, thanks again | 22:24 |
