Re: I'm about to throw my N900 because of hildon-thumbnailerd

However Linux isn't the cause of any of the over loading on the device... Maemo's daemons are, they aggressively leech the n900 like a spyware infested Windows machine. All they need is improved throttling or even better, scheduled indexing at idle usage or overnight while charging. Anyway, lets make this thread useful... To get the n900 running like it should you need to kill indexing with Tracker Cfg, disable your repositories so Apt doesn't activate once you get internet connectivity, over clock to 1Ghz and add the swapiness config changes. |

Mine won't OC to 1 ghz, 900 is how much it takes for the team =)
The other tips are great though, thanks! Had no idea apt activated every time I have internet conectivity. Does disabling all repos fix this? Also, how do I change the tracker config? |

For example, why the hell they put 100 in swappiness? This is lame! Why the hell this stupid job don't do "his job" correctly? Obvious once I have thumbs done, and no modification in my files, I DON'T NEED IT TO RUN AGAIN! Or at least, put it with a low nice (or low priority)! That's like childish from Nokia, really stupid! N900 could be the best... but it is the best one day and the worst two days... |

That is a spot-on assessment. Maemo certainly shares in the weaknesses and strengths of the desktop linux experience. Being somewhat familiar with desktop pc versions, my n900 actually turned out better than expected. |

For the other configs I have a script I run manually in xTerminal after a restart. It over clocks to 950 Mhz and does the swappiness changes, I might make it a permanent change after a few more weeks, I havn't had any problems with it so far and things run tip top. Code:

What does all these do? Could you explain your script a bit more? I'm on a quest to get the maximum battery out of the phone..

In the process, I did discover that "laptop_mode" is almost certainly useless. Roughly speaking, it cleans out old parts of the swap opportunistically any time any other I/O occurs - this saves power on a laptop because that way you avoid spinning up the hard drive *just* to handle swap cleanup. Last I checked, though, the n900 does not have a mechanical hard drive - unless someone's come up with a new mod I haven't heard about ;) - and so this is unlikely to be helpful. (It's probably equally unlikely to be harmful, though, so, meh. :) ) I therefore suspect some of the other tweaks listed may arise from a similar "shotgun approach" to tweak application, but I haven't looked all that closely. |
