There is a major fault in the radio system of this bad laptop. I do not recall what you have tried so far, but my advice is to change the system a component at a time to find out which component is at fault. There are only three components that can be changed; - change the left-hand antenna and coax, - change the right-hand antenna and coax, - change wireless card. Test again after each change. Record the results. Identify the faulty component and replace it. Predictable causes of failure for each component: - antenna physical impact damage, - water in antenna case, - broken coax cable termination inside antenna, - coax cable twist, compression, abrasion or water damage, - coax cable connector physical damage, - wireless card connector physical damage, - wireless card electrostatic discharge damage, - wireless card water damage, - wireless card product lifetime or thermal cycle damage. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

And finally a 1.75 image http://bender.sugarlabs.org:3000/images/xo1.75/1/ Testing on this would be appreciated because I don't have a working 1.75 with me. Now I'm going to try to get the olpc-os-builder changes upstream and setup the infrastructure bits more solidly on docky.sugarlabs.org (a vm I setup yesterday). Then I'll do builds with the fixes Martin sent.

We can start with the activities used by example in AU, but add more based on deployment requests.

Tested here, Sugar starts ok. Wifi ok. Downloaded and tried a few activities. Physics crashed and Browse crash on youtube, but other work ok, and I don't have numbers, but all feels a little faster.

Re: [Sugar-devel] restart by ctl+alt+bs
BTW, as a workaround I use when all I need to restart is X, I switch to a virtual terminal (ctl+alt+f2) and type "killall X". That will avoid the full reboot cycle and restart Sugar.
