powerd or ohm?
Hi, I think f11 for the XO 1.5 uses ohmd but from a recent message from Paul I think the images for the XO-1 are configured to use powerd or at least doesn't start ohmd by default. Steve, is there any plan on this? Thanks, Tomeu -- «Sugar Labs is anyone who participates in improving and using Sugar.

Testing OS64 on XO1.5
I was testing latest os (OS64) on XO1.5 with latest firmware (Q3A25) this weekend. There are some thing that I think may be bugs, but before reporting it I'd like to see if others experienced similar problems. Everything below applies to Sugar on OS64 on XO1.5 - I did not test gnome. 1) After reboot, or after a brief period of inactivity, the system sometimes does not connect to network, or disconnects from the network, and shows nothing on the network neigborhood screen (many dots button), only the middle xo symbol, while there are many wireless networks around - this happened at least five times in 6 hours of testing, either aftrer reboot or after a brief inactivity. No such problem on the XO1.0 system tested in parallel. This seems the biggest issue. 2) In the Record activity, sound does not work - I tried to record some fairly loud speach, saved it on the bottom, but on replay of the saved clipping, a very (etremely) low sound - almost no sound, certainly not distinquishable at all. Speakers were unmute and on max. 3) Record activity does not maximize the camera view to the whole screen (aftger hitting the maximize button) 4) In Etoys, sound does work reasonably loud, but is very jittery. 5) With power unplugged, leaving the XO1.5 untouched for 15 minutes (or so, did not measure exactly), all lights go off, only the power light flashes. This is OK, but no mouse or keyboard action , only holding the power button for about 2 seconds, brought the system back from sleep . Is this normal or expected? It does not seem right.. 6) There is no shell activity. Is that an intention to hide the filesystem? Milan ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Testing OS64 on XO1.5
Milan - 1) After reboot, or after a brief period of inactivity, the system sometimes does not connect to network, or disconnects from the network, and shows nothing on the network neigborhood screen (many dots button), only the middle xo symbol, while there are many wireless networks around - this happened at least five times in 6 hours of testing, either aftrer reboot or after a brief inactivity. No such problem on the XO1.0 system tested in parallel. This seems the biggest issue. Thanks for the testing. All B2 XO-1.5 machines (virtually all of the ones distributed outside of OLPC) cannot resume properly after suspending. The WLAN will disappear and won't come back until you reboot. This sounds exactly like the symptom you're seeing. It's been fixed on later hardware and will be fixed in the production version, but it will never work properly on a B2 machine. If you need WLAN access after suspend/resume (which will indeed occur after a brief inactivity) use the Sugar Control Panel / Power settings to disable automatic power management - both checkboxes on that panel should be cleared). If you don't need WLAN operation, it is helpful if you don't clear this setting, so suspend/resume operation continues to be tested for more bugs. - Ed ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

XO-1.5 video rendering not always smooth
In the new snow-1.xo Activity, the falling white spots are noticeably jerkier in os64 (XO-1.5) than in os10 (XO-1). Also, on os64 the (software?) cursor sometimes flickers annoyingly. It is always noticeable in the google-chrome browser (on Sugar), and for instance in the new version of the cartoonbuilder-7.xo Activity.

Re: [Server-devel] Managing global site resources when using segregated groups
On Sun, Dec 20, 2009 at 1:27 AM, David Leeming da...@leeming-consulting.com wrote: I am getting to grips with the impressive functionality of 0.6! Surely you exaggerate ;-) - I have global resources, i.e. a general library for everyone to view. I set this up as a course called “Library” and added (a) a link to a public folder that I set up on the XS, and (b) course folders with resources uploaded from the admin XO. I want ALL users to be able to see this course on the front page of Moodle. Initially, users are NOT assigned roles as students in the Library course. I set guest access. That is a good start. Some hints (that you may be familiar with)... A better alternative to achieve what you are after is to use a _glossary_ in the 'site course' (the moodle homepage is a course with a single section -- turn editing on to add a glossary there). It goes like this - with the 'coursecreator´ XO, visit moodle homepage - turn editing on - add a new glossary -- name it 'Library' - add entries as desired, attach files where needed... - mark it as global (or sitewide) glossary now, here is where it gets advanced... if you can login as the 'admin' user (see the 'XS Techniques' wikipage), go to the 'filters' configuration, and activate: activities autolink, glossary autolink. Details here http://docs.moodle.org/en/Filters (XS-0.7 will have these filter preconfigured...) Now, if you have a glossary entry called Foobar, *any* text that mentions Foobar will be auto-linked. You can use 'Resource auto-link' but that is per-course, and won't take a global set. So a global glossary is your ticket... - I am wanting to divide my users into two classes, by setting up 2 courses Class A and Class B, adding some to each using the admin XO course admin, assign roles (students) Good. I switched on Presence and it works, i.e. members of Class A can only see each other and members of Class B can only see each other. Both classes can see the teacher (admin XO in this case). Excellent! The teacher can access the Library and share resources with ALL users at the same time. However, users can not see the Library themselves to access resources on their own. Global glossary to the rescue... I then added all the users to the Library course, as students. Of course, predictably they can now see all the members of the other classes. Yup, understood. Global glossary... A second question, two of my test XOs are B4s. In Moodle the front page comes up as a log on screen asking for username and password, despite the fact they are registered and appear in the admin OK.

Re: [Server-devel] Managing global site resources when using segregated groups
That was very helpful, Martin. I will try the global glossary. I also noted that if users are added as guests only, then they can see the resources but are not connected by the presence service. A less elegant way to do it perhaps. On the B4s below, well I have two C1s and 2 B4s and they were all updated with exactly the same flashdrive (build 802 and same activity bundle). So they should behave identically apart from hardware issues. But the issue below remains, any other clues I can look for? A second question, two of my test XOs are B4s.

Re: [Server-devel] Pushing Activities to XOs
Also, is it now, or will it be, possible to have activities updated automatically by the server? I am noting some oddities with software updating and also inconsistencies with the OLPC and Sugar sites. Some (the C1s) XOs report all well - no need to update. Some (the B4s) report a long list of updates needed. But they have exactly the same versions of activities loaded. I go to the OLPC wiki activities page and the latest version download links are not being updated by the look of it. Anyway the problem remains, you have 100+ XOs in a school.
