Help with Boot Helpers?
by Caroline Meeks 30 Mar '09

30 Mar '09

Last week Mel and I went to two schools in Boston to see how Sugar on a Stick would fare in the wild. Notes are here: http://wiki.sugarlabs.org/go/GPA http://wiki.sugarlabs.org/go/Shaw_Elementary_School The short summary is we think a wider range of "Boot Helpers" would be very helpful. One thing that we specifically need help with is getting the boot-helper CD updated from F9.9 to F11. Marco made the F9.9 version a few months ago: http://wiki.sugarlabs.org/go/Sugar_on_a_Stick Its under Gary's name, it was lost and Gary found it and uploaded it, but Marco did the original work. Relevant tickets in dev.sugarlabs.org include 263, 265 for the CD version More generally 579, 597 and 598 for the various different types of boot helpers. Thanks to much work by many volunteers we are getting close! We have enthusiastic teachers, especially at the Gardner, chomping at the bit to try Sugar! Please help if you can. Thanks!!!!

Question - where to report usability problems with rawhide-xo ?
by Mikus Grinbergs 30 Mar '09

30 Mar '09

The ~cjb images for rawhide-xo are good enough that I've been able to run quite a few applications on my XO. But while logged in to Sugar (e.g., with 20090326.img on the XO), I get neither sound out nor a "moving picture" out from applications meant to produce those. I do not have any particular test case -- *none* of the applications I've tried (they all run properly on 8.2.1) produce sound/video for me. [And some of those applications have taken me hours to install, and would require even more hours to detail a "how to install".] Nevertheless, I feel audio/video lack in rawhide XO is serious. The existing OLPC tickets I've found on bugzilla.redhat are mostly about __build__ problems. What I'm seeing are __usability__ problems. Where (and how) should I report lack of audio/video output on an XO? mikus

Fwd: Question - where to report usability problems with rawhide-xo ?
by Frederick Grose 29 Mar '09

29 Mar '09

It seems a release goes through a number of stages where the release team focuses on progressively more of the intended capabilities of the packaged content. Those not directly involved often wonder about the state of the progress and the whether or not those involved know about what a tester is observing. During these rapidly changing stages of release building, the Trac ticketing system seems to be too finely grained to provide a general picture of the state of the progress. I suspect that there are other methods to learn what is wanted. Please point to examples of success. Not knowing any better, I've posted these pages on the Sugar Labs wiki for the Sugar on a Stick project , http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/GettingInvolved (see the subpages). Perhaps similar pages are needed for the Rawhide XO release. Those involved, please advise. --Fred On Sun, Mar 29, 2009 at 9:27 PM, Mikus Grinbergs <mikus(a)bga.com> wrote: > The ~cjb images for rawhide-xo are good enough that I've been able to run > quite a few applications on my XO.

Re: XO freeze
by Mikus Grinbergs 28 Mar '09

28 Mar '09

I've now had a number of times that my rawhide-xo 20090326 XO "froze". Two of those times were while I was using yum to try to (download and) install Java -- that makes me think that the XO is running out of memory (it only has 256K), causing the lock_up. I see that there is a whole boatload of updated modules (including yum) available in the rawhide repositories -- let's see whether the "XO freeze" keeps on happening once a newer image gets built. mikus

On Mar 12, Gary Martin posted the status of the Activities on Soas2.

They installed ok with 'sugar-install-bundle', but apparently their information was not stored in the 'activity registry'. As a result, Sugar behaved as though those activities had not been installed. mikus

Sugar and X problems logging in to Soas2-200903271806 on an XO-1
by S Page 27 Mar '09

27 Mar '09

I have an XO-1 with OFW q2e33 and have intermittently tried out Rawhide-XO builds and SoaS 2 builds with varying success. I downloaded Soas2-200903271806.iso and ran latest LiveUSB-Creator 3.6.3 under Windows XP to put it and a 256 MB persistent storage area on a USB flash drive. The USB flash drive is "2GB" (approx 1,900,000,000 bytes) USB flash drive with a handful of other files on it. Insert the USB flash drive, power on XO-1, hold down check key. The hot dog is back! After a minute the screen goes dark. After another 90 seconds of dark screen I get the blue swirl Login: screen with "liveuser", Log in. After several seconds that goes to dark screen, and a few seconds later I'm back at the blue Login: screen. :-( In a console, ~liveuser has no .sugar subdirectory, so it looks like Sugar never got rolling. The file "/var/log/slim.log" has various tantalizing errors. The whole thing follows. Should I try tinkering with DISPLAY and permissions? There is no /home/liveuser/.Xauthority file, and /home/liveuser is drwx-r-xr-x owned by root, not liveuser, so it seems odd. Hope this helps. Is there a Talk page somewhere on SugarLabs.org to report success or failure with SoaS 2 builds? -- =S Page /var/log/slim.log contents: /usr/bin/xauth: creating new authority file /var/run/slim.auth X.Org X Server 1.6.0 Release Date: 2009-2-25 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.18-128.1.1.el5 i686 Current Operating System: Linux localhost.localdomain 2.6.29-0.258.2.3.rc8.git2.fc11.i586 #1 SMP Tue Mar 24 18:37:23 EDT 2009 i586 Build Date: 12 March 2009 01:39:32PM Build ID: xorg-x11-server 1.6.0-13.fc11 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

XO freeze
by Mikus Grinbergs 27 Mar '09

27 Mar '09

Twice now with rawhide-xo Sugar (once on 20090325 on one machine, and once so far on 20090326 on a different machine) my XO has 'frozen' -- *none* of the inputs have any effect whatsoever (except that I can use the 'power' button to power off). [The principal "unusual" customization I perform on those systems is to add pointers in /home/liveuser/Activities to additional Activities I've unzipped onto my SD card; I'm also using a swap partition; I question whether either of these have any affect on the freezing.] [With earlier rawhide images, had same setup, but without freezing.] Both times, I was in the middle of a perfectly innocuous CLI command ('yum', 'find'). Obviously, since I had no way to see what the system was doing (alt-ctl-F2 doesn't work), I have no information to give about the 'freeze' (nor any way to deliberately reproduce it). [After rebooting, /var/log shows nothing unusual.] mikus

Hi, I wonder if a Sugar special interest group - similar ti that of KDE http://fedoraproject.org/wiki/SIGs/KDE might help to coordinate the efforts. What do other people think? Thanks, Simon

Browse-105 does not work for me
by Mikus Grinbergs 27 Mar '09

27 Mar '09

Tested Browse-105 (as installed in rawhide-xo 20090325) in an environment with an AP. Browse would launch, but as soon as it was asked to show an useful webpage, it would disappear. [The only page it managed to display was the main search page at the Google site -- but when I clicked within the search results, Browse vanished. In contrast, the Firefox-6 Activity ran fine (in Sugar on 20090325); (in Gnome on 20090325, rawhide's firefox executable itself failed with the error message: "illegal instruction").] The first set of activity logs showed that (when using a wireless connection) the pages Browse sought to display needed additional modules not installed in 20090325. [For instance, for one webpage it needed 'm4' -- Browse-102 explicitly installs 'm4' in Browse.activity/bin (but Browse-105 does not)!! After I used yum to fetch and install 'm4', Browse-105 kept failing for lack of other modules, such as 'acroread'. And with some webpages Browse-105 would vanish after starting to display the page -- but the activity's log would show only 'ordinary' lines -- I'm guessing that whatever crashed Browse, did not give it a chance to write any error description to its log. Tried Browse-105 without an AP (with rawhide-xo 20090326). It vanished when I tried to go to about:config (for use at home, I needed to tell Browse how my home is connected to the internet). mikus

(I should really go to sleep early on some days) I have just pushed an initial edition of pyxkb to Git: http://git.sugarlabs.org/projects/python-xkb It works for me (though it may crash if you don't use it under ideal circumstances). Some examples: #Get a list of all the layouts pyxkb.get_layouts() #Get a list of all variant for the 'us' layout: pyxkb.get_variants_for_layout('us') #Get the enabled layouts: pyxkb.get_current_layouts() #Enable 'us(olpc2)' and 'af(olpc-ps)' layout: pyxkb.set_layouts(['us', 'es']) pyxkb.set_variants(['olpc2', 'olpc-ps']) I think the above should be sufficient to implement a basic keyboard configuration control panel extension for Sugar.
