Re: hdmi out
OK, with tail -f ... messages, I do see a burst of messages and the projector shows the exact screen. But only for 15 seconds, when the projector then goes blank and reverts to _No Signal_ until I touch something on the XO like the screen, track pad or some key. Apparently the XO has stopped sending hdmi signals, so the projector is reporting exactly that. Is this the XO hdmi port going to sleep? And do I have control over some time constant? Or perhaps my projector is going blank when it sees no recent activity on the port. Might it be expecting at least a screen refresh over the hdmi channel? I don't have a projector manual that would describe that ... It seems I can jiggle the HDMI cable a fair bit without issue, so I think the physical connection is sound.

Re: Auckland Testing Summary 6 July 2013
Tom (and I've added Rangan to this thread because Manaia is our first XO-Duo deployment). Thanks for your comprehensive testing yesterday. I trust we can resolve at least some to these before Tabitha and I reflash the 25 new Duos in Manaia on Tuesday. NB: I've noticed another issue on the _Touch interface_ -- when starting any activity via Touch, there's _no choice_ of whether _Resume _or _Start New_. We always get _Resume_. The Start New option comes only via the keypad or external mouse pointer. Is this the intended behaviour? -- barry On 6/07/2013 10:01 p.m., Tom Parker wrote: Auckland Testing Summary 6 July 2013 Who: John, Tabitha, Tom Testing XO-system 1a For XO-4 (build 46) Sugar 0.98.7 Firmware Q7B35 Found that my previously described customization script was not working right -- the /etc/sysconfig/keyboard change is overwritten during first boot! Updated the customization script to also hack olpc-configure. Will look at options to do this better later. Found that this build does not include the Maori translations for sugar itself. Worked with CJL to get the language pack into the customization script. We’re not sure how we missed this as we have done a moderate amount of testing with Maori in previous builds, perhaps we saw the activities translated to Maori (activities are built differently) and just didn’t notice that sugar itself had no Maori. The language selector is awful. It’s slow to appear, the drop downs don’t work the first time you use them and they scroll very slowly compared to the number of entries but too fast to easily spot your desired language. Sometimes when changing the language, when you click the restart now, nothing happens. If you click restart later and then restart the whole laptop the changes seem to take affect. Some activities that we were expecting to be there, were not (maybe we are getting confused between builds prepared for different deployments). There is no GetBooks but there is Read (without any books!). There is also no Infoslice. There is no SocialCalc. There is no eToys. In Browse we went to activities.sugarlabs.org and tried to use the touch screen to write in the search but that didn’t work, you had to use the touchpad button to activate the search box. You also couldn’t just touch the button that starts the search, you had to use the touchpad button (or enter key). You could however use the touchscreen to select the activity to go to the activity page and touch to select download. Activities did however download successfully, install and run (like the Music keyboard activity btw). There used to be a menu on the left side of the homepage in Browse but it has gone on all the XO-4 homepages. You used to use that menu to access maps, images and sound files, as well as any published Infoslice activity. Maze works. Paint works well with touchscreen. Physics works well with touchscreen. Implode works well with touchscreen. Portfolio works. Measure works well with touchscreen. Labyrinth works. Write works and the Maori Macrons (now, after some changes) work. The insertion of a table changes the font to times new roman which is not actually a listed font available in Write. We’re not sure if there is a camera in the XO-4 SKU 303 serial SHC318001EC we just got from Australia, there is something there but it is at best mis-aligned. This laptop did get banged against a wall on it’s handle while it was closed. The direction of the impact was mostly parallel with the plane of the shut laptop and wasn’t too severe. Could this move the camera in the body of the laptop and also break it? Firmware camera test fails, record behaves reasonably (it only offers to record sound). Barry reports the second XO from the pair in this shipment has a working camera. The XO-4 we got from Boston does recognise it’s camera on and it can take high and low quality video well. Will take photographs and wait for advice before opening. Moon still fails to start when the XO language is Maori. Previously reported in https://sugardextrose.org/issues/3971 Clock - loving the new grab hands feature, still doesn’t talk when XO is in Maori. Maori issue also reported in the same 3971 ticket. Labyrinth and Maze are both called Kōwhīwhiwhi - suggests an inappropriate translation of Labyrinth (guess it should be translated to a word more appropriate for brainstorm/mindmap activity). On some laptops terminal is called Terminal and on others it is called Kāpeka. WikipediaEN has not had an activity name translation either but this might be deliberate. Turtleblocks activity has a partial translation inside the activity due to new blocks being added. The name of the Turtleblocks activity has not been translated (but again that might be deliberate). ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Māori Macrons olpc keyboard
Tom, it's not correct to say the laptops will remain in Maori. Many schools have both Maori and English classes, and the ability of these machines to cross the boundary, to have a child work either in their first language or (with a simple switch in Settings-Language) to gain experience in another, is one of our strong features. Having the switch relatively easy is a great, and I've seen some kids do it while I'm supposedly talking to them. Incidentally, there's a _bug _when declaring the second language second. It seems that whichever language is _last declared_ becomes the current language in which alternative languages are expressed -- as for instance for the list within _Speak_. Since I don't yet have a Maori version of the ESPEAK voice engine (takers anyone?), and since English pronunciation and prosody is a poor substitute, I routinely tell the children typing in Maori to set the _Speak _language to Vietnamese. This is a surprisingly good substitute. But it becomes hard to find if someone has last set the login 2nd language to Arabic. This bug shouldn't be hard to fix. Until then, declare your #2 language first, and your #1 language last. -- barry On 25/06/2013 10:51 p.m., Tom Parker wrote: On 24/06/13 23:43, Walter Bender wrote: Which build are you running?

I don't think a keyboard settings control panel is immediately necessary as the laptops will remain in Maori. It would be good in a future release if we could say after reflashing, set your language and keyboard to maori without having to resort to customizations. Meanwhile, we may have to make a new X keyboard symbols file for you that does the right thing. Not impossible to get upstreamed. I wasn't really able understand the /usr/share/X11/xkb directory, but using xkbcomp to retrieve the current config, modify it and return it to the X server does the trick. Is there a document that describes the right way to add a keyboard and select it? Using xkbcomp in a startup script might work but is obviously a hack. http://wiki.laptop.org/go/Creating_A_New_Keyboard_Layout seems to cover this but appears to be out of date. Until we get feedback from the actual users about what they want their keyboards to do, I think it's best to customize the build they have rather than upstream something and get a new build. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

In OLPC's Dextrose's versions of sugar the sugar-cp-keyboard rpm doesn't get installed. Think there is a conflict over the keyboard with olpc-configure supplied by olpc-utils. I can poke around to see if I can get it to work. -walter Jerry Meanwhile, we may have to make a new X keyboard symbols file for you that does the right thing.

It seems that the olpc us international keyboard binds a ̄ COMBINING MACRON (unicode U+0304) to algr + hyphan. When typed after the letter a you get ā which is similar to but not the same as ā LATIN SMALL LETTER A WITH MACRON (unicode U+0101). Issues I've noted with a small amount of testing: On older builds, Write does not correctly load files containing the combining macron. The combining macron is not rendered at the correct height for lower case letters. (on older builds this seems to be the case all the time, on newer builds, it is rendered correctly after loading a file until you delete a following character the on the same line, then it jumps up) You can have more than one combining macron, they stack. You have to delete twice, once to delete the macron and again to delete the character. Have these issues come up before? I don't see any. I will raise tickets for the bugs rendering the macron in the latest version of write shortly. I'm not sure if anyone wants a ticket for older builds? Obviously stacking macrons is by-design when using the combining macron character (see https://twitter.com/glitchr_/ for more improbable outcomes of combining characters, perhaps your browser will crash). I haven't yet experimented with entering the ā U+0101 characters into sugar (tomorrow!) Apparently on Windows, the Māori keyboard is set up such that when you hit the grave (apparently this is what I have always called the backtick) key and then one of the vowels, you get the macron version of the vowel. I haven't seen this in action but Māori typists claim it is very efficient. Gnome on Ubuntu on my laptop binds right-alt-a to ā U+0101 when using the Māori keyboard layout. I'm not sure how Maori typists feel about this inconsistency with windows. When you choose the language in sugar, can this change the keyboard layout too? If not, what is the recommended way to configure this? How complex is it to change the localization of the keyboard for the Maori language? The xkb files don't look too complicated. Is the grave - vowel = macron vowel possible while still preserving the backtick for shell scripting? I haven't seen the laptops in question but I'm told they have the Australian simplified key caps, so changing the existing alt-gr mappings to render macron vowels (ie to mimic the Maori keyboard option on Gnome-Ubuntu) instead of the existing mappings won't confuse the key caps. Obviously touching all the laptops to change how the keyboard works is a pain and the change is potentially erased by future updates. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel -- Walter Bender Sugar Labs http://www.sugarlabs.org ___ OLPC-NZ mailing list olpc...@lists.laptop.org http://lists.laptop.org/listinfo/olpc-nz -- Walter Bender Sugar Labs http://www.sugarlabs.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: ARM gcc with alsa
Gozalo Well, the targets of most Csoundxo bindings don't exist in Fedora 14 Csound, which sadly doesn't comply with the full Midi spec, nor does it have fixed-point opcode options which in Csoundxo run about 60% faster on most processors (I've yet to test this on the 1.75's Armada 610). Faster audio processing frees up more mips for graphic interaction -- such as in the XO Music Painter activity. The fork came about since my original Csound was developed for larger machines (and has continued that tradition), while Csoundxo is tailored to lower-power processors which conform to the price-point of affordable XO education in really disadvantaged countries. The TamTam suite isn't a good example since it makes mostly trivial demands on either Csound. I will continue trying to resolve the ALSA issues for Csoundxo, which runs just fine on 386 installs. Any help appreciated. -- barry On 9/23/2011 1:33 AM, Gonzalo Odiard wrote: On Wed, Sep 21, 2011 at 5:33 AM, Barry Vercoe b...@media.mit.edu mailto:b...@media.mit.edu wrote: I'm the original author of Csound, and more recently of CsoundXO made especially for the OLPC XO laptop.

Can the bindings be packaged, and use the csound version available in Fedora 14? This bindings, can be used by example in the TamTam Suite? Regards, Gonzalo To compile csoundxo on the latest XO 1.75 ARM machine I did the following (native): yum install gcc yum install alsa-lib-devel-1.0.24-1.fc14.armv5tel.rpm gcc -o csoundxo -I/usr/include -I./include -D_POSIX_C_SOURCE -L/usr/lib -lasound -lm ./csrc/*.c The install appears to be missing an alsa component, including I suspect a PulseAudio plugin config, which then fails to resolve references to things like snd_pcm_sw_params_t Where do I find the right code for this ARM machine?
