Installing powerd on earlier F11 builds
We're still grappling with the aftermath of http://dev.laptop.org/ticket/10402 XO-1.5s that have been damaged from overheating are being replaced, but we also need a means to prevent others from meeting a similar fate. Our preferred solution is to upgrade to our latest build, which has a fixed powerd. However, we are finding that many teachers are unable to do this (due to lack of time, etc.). For them, we are devising a simple means for them to specifically update powerd on their systems. This method employs a modified customisation stick[0][1] to automatically install the RPMs. A challenge is that the XOs came from the factory (starting in May 2010) with a range of builds ranging from os65 to os203. The earlier builds have power management handled by ohm[2] instead of powerd. This raises some questions: 1. are there any problems with simply removing ohm and installing powerd? 2. at what point did powerd become usable in F11 XO builds? 3. are there any other changes that we need to be aware of, e.g. in the power management panel in My Settings in Sugar? 4. do we need to upgrade the firmware as well? 5. is there anything else that we need to be aware of?

A few days ago, I got a mockup for how the gnome-control-center plugin should look like so by the time F16 comes around we should have a UI. that probably won't affect you too much with sugar tough. If you're on a F14 system, I simply recommend getting the 0.11 driver. I can probably update F14 to 0.11 but i'm rather hesitant because new syntax would break scripts. As for the cost - hard to judge. the tablets are all several hundred dollars. Bamboos are the cheapest option but also the trickest to keep working. Luckily Chris Bagwell has done tremendous work on the bamboos to keep them working, so the same applies - out-of-the box works fine, excessive configuration may show issues. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Installing powerd on earlier F11 builds
hi sridhar -- i'll take a stab at more detailed answers to all of these questions tomorrow.. powerd was developed initially on machines that had ohmd installed (i think the rpm still tries to uninstall ohmd first) so it's probably not far from working. but it's entirely possible (likely) that some support for older kernels has been lost along the way, or, more correctly, that newer powerd features depend on fixes/features in newer kernels. obviously a system upgrade would be preferable... but i'm sure you feel the same way. :-) paul sridhar wrote: We're still grappling with the aftermath of http://dev.laptop.org/ticket/10402 XO-1.5s that have been damaged from overheating are being replaced, but we also need a means to prevent others from meeting a similar fate.

Re: [Server-devel] [Sugar-devel] [IAEP] copy files to/from server
As I mentioned before, I am currently working on the multi-selection support for Journal (which is a prerequisite for the cloud journal and explains why I haven't been very active on this thread). Anyway, I am listening to other's technical and non-technical ideas, but _my_ approach is first to provide extra storage capacity on the XS in the most transparent way to the end users. Therefore, In the non-technical front, I believe we should stick to the Journal integration idea, displaying this resource exactly how we display removable devices. In the technical front, I haven't checked all the solutions mentioned but I would definitely go with something that _already_ provides support for regular file system interaction. With something like that (and please someone let me know if I am wrong), the integration part will be a lot easier, like i.e (as Walter commented) we could use his/mine/jasg documents folder patch.
