i810 dual-pipe issues with power management

Friday, May 9th, 2008

I have had a problem with my IBM X41 – ever since I have started using Ubuntu 7.10 (after a nice upgrade from 7.04), whenever the lid was closed, and reopened – the display would have flickered for a short while (while the lid is up) and then blank completely.

My (ugly) workaround was to force the computer to sleep whenever it happened. It seemed to be a workaround good enough for most cases. On some cases, the laptop would do just the same as it was placed in its docking station.

I have found an Ubuntu bug here, which seems to expose this problem too. It exposed few additional problems as well. The error message I got (through SSH, of course) when viewing the logs it said that the video card detected pipe A to be the active pipe, that it stopped using pipe B (which appeared to be the internal one) and that it decided to disable clone mode. Wow. I just lost my internal LCD. Connecting an external display, I get the whole picture working just fine, however, I cannot use the laptop like that.

After a major struggle with various i810 options, I have looked and found an option to disable Power Management. I have done so, according to the note here, and it solved all my problems in this area – for now.

The first biological portable computer

Tuesday, June 19th, 2007

This is not exactly a technical post, but I had to bring it online.

I am proud to be one of the first persons, if not actually the first one to own a biological portable computer (BPC). You will find no other such thing, I think. I have searched Google, after all.

Although the docking station, or Biologic Electronic Interface (BEI) looks quite similar to the IBM X40’s docking station

The docking station, or Biological Electronic Interface (BEI)

You can see the difference. Unfortunately, in this picture you cannot clearly see the micro conductors which are used in the BEI plug, which is, actually, the method of connecting a simple and regular USB mouse to the BPC.

The BPC has the ability to self support. It is self propelled, and will walk(!!!) back to the BEI whenever the need arises. It has the computational power of hundreds of normal PCs, and although it runs its own unique OS, it has a simple interface which accepts commands. In the picture below, you can see the BPC in its docking station, charging.

As said, accepts commands, but only seldom performs them. It’s a prototype, and yet has a way to go. It has to fit the docking better (this prototype BEI has been developed as a case study), and should go through more modifications until it can be sold commercially. Yet, very impressive.
