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.

We are not using it. I am pretty sure Nicaragua use it. Is AU using yum? Yes, we use a deamon calling yum with a particular configuration. Recently I am testing dnf in F20, and I am impressed.

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. On 13 May 2014 04:27, Martin Abente martin.abente.lah...@gmail.com wrote: Downloading!

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
