Broken XO-1 battery (battery LED flashes red)
Hi The battery LED is flashing red and ec-abnormal@ . at the OFW (version Q2E41) prompt gives back the value c. What does c mean? Can it be fixed? Regards, Philipp ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Keyboard/Mouse problem after resume: - external USB keyboard works fine after resume - I have attached an extract of the messages file with suspend, wait 5 min, resume (suspend and resume with power button), but I don't know what could be related to keyboard/mouse.

Hi Steven - The scratch sensor board doesn't work (works with build 802) I hoped allow olpc access to ttyUSB nodes (from release notes os10) would make it work. I added an extract of /var/log/messages at the bottom of the email. - timezone can not be changed in gnome since administration menu is missing (changing the timezone in sugar control panel has no effect in gnome). And talking about time, I think the clock activity is really nice and useful. - build information OLPC release 11 (Leonidas) in sugar control panel is more confusing than helpful.

Re: Some testing notes for OS10 for the XO-1
The Prolific driver gets loaded (see logs at the bottom). The problem are the permissions. After plugging in the scratch board ll /dev/ttyUSB0 shows: crw-rw 1 root dialout 188, 0 2009-12-14 09:52 /dev/ttyUSB0 User olpc is not in group dialout which means it doesn't have access to ttyUSB0. After adding olpc to group dialout the scratch board works fine. Regards, Philipp On 12/13/2009 11:17 PM, John Maloney wrote: Hi, Steven. The USB-serial cable that comes with the Scratch Sensor board needs a driver from Prolifix. That driver used to be included in the builds, but perhaps it was accidentally dropped? If you use a supported USB-serial adaptor cable, then I think the ScratchBoard will work. I just got a report that sound playback is rough on XO 1.5: http://dev.laptop.org/ticket/9375 I'm guessing this is caused by a switch from ALSA to PulseAudio. We've seen that on Ubuntu; we still working to resolve the problem. PulseAudio itself has some buffering issues, although it appears that folks are working on those. The problems tend to show up more in applications where sounds are triggered dynamically, such as Scratch, EToys, and games, vs. playing music. -- John On Dec 13, 2009, at 4:00 AM, Philipp Kocher wrote: Hi Steven - The scratch sensor board doesn't work (works with build 802) I hoped allow olpc access to ttyUSB nodes (from release notes os10) would make it work.

Re: About 8.2.2
Hi Ed, Martin What is the plan for the Fedora 11 build for XO-1, will OLPC sign such a build or is 802 the last build signed by OLPC? I don't think one of the two options is a good solution for small deployments without a tech team. I think for the case of Cambodia with many small deployments (educational NGOs got XOs donated from G1G1/OLPC or other donors), no signed builds probably means that the XOs don't get updated anymore.

That implies a higher level of testing and certification than an image that can be selectively adopted by specific deployments who can do their own testing to decide whether that release is suitable for their application. As OLPC's deployments grow both in number of total laptops deployed and in the number of different localities supported, it becomes increasingly burdensome / difficult to package and test One Image to Boot Them All worldwide. As Martin points out, we are continuing to try to move users toward either (a) using machines with boot-image security disabled, so they can run any software, or (b) using locally-developed and locally-maintained signature authorities to sign OS images for secure boot in local deployments. - Ed On Dec 1, 2009, at 4:14 AM, Philipp Kocher wrote: - It won't be signed by OLPC.

Fwd: Re: Importing images in Write documents makes file huge
Bonjour Hubert I read on planet.abisource.com (June 26, 2009) that you implemented the JPEG support for abiword 2.7.6. This feature would be very useful for OLPC XO laptops, but the newest release (8.2.1, build 802) for XOs includes still abiword 2.6.4. Is it possible to make a small and low risk JPEG-patch for abiword 2.6.4 so it could be included in release 8.2.2? Work for a Fedora 11 based release (8.2.1 and 8.2.2 are based on Fedora 9) is in progress. This release includes abiword 2.8.1, but it won't be stable enough to install it on student XOs soon (I am not aware of a schedule for this release).

Importing images in Write documents makes file huge
Hi all,
We would like the students to create simple html-documents with text and
images and upload them to the schoolserver for a simple homepage. The
Write activity (we are using version 60 on build 802) has a feature
Keep as Hypertext (HTML), but when images are inserted into the
document the files get huge (10 times bigger than original image).
If I check the file size in the datastore, an image created with Record
(file size 38kB, mimetype image/jpg) inserted in a html document
containing nothing else than the image, the html file is 554kB (mimetype
text/html).
The image is saved in the html-document with:
img ... src=data:image/png;base64,{image data}
I can do the same thing with Abiword 2.8.1 and the html file is just
52kB, probably because it is using jpg:
img ... src=data:image/jpeg;base64,{image data}
There is an old ticket for that (last modified 2 years ago):
Ticket #1442 non-PNG image support for Abiword
Any suggestions for a workaround? Is there an other activity we could
use to create html pages?
Best regards,
Philipp
PS: other document types created with Write have the same problem:
image/jpg: 38kB (created with Record activity)
application/rtf:821kB (created with Write activity)
text/html: 554kB (created with Write activity)
application/vnd.oasis.opendocument.text: 406kB (created with Write

Re: Importing images in Write documents makes file huge
The conversion to PNG was a general Abiword feature, but it got solved
last July with Abiword 2.7.6 (see link below).
On my XO libabiword-2.6.4-6.olpc3 is installed (build 802).
Is it possible to install an libabiword-olpc rpm of version 2.7.6 or newer?
http://planet.abisource.com/:
July 04, 2009
Marc Maurer: Impressive AbiWord release
We just released AbiWord 2.7.6, which is an awesome release in my opinion!
It for example adds native JPEG support, so we don’t convert every JPEG
internally to PNG anymore. This will be of great benefit on the OLPC
laptop, where kids use built-in camera to produce photos in JPEG format
and add them to their document. This will greatly reduce the filesize of
their document. It will also be a lot less bandwidth intensive when
collaborating on such a document.

Is it possible to install an libabiword-olpc rpm of version 2.7.6 or newer?
I guess it depends on how many technical resources you have, but it's
definitely possible. Though maybe the best way forward is helping with
the effort of making F11 work well on the XO-1s.

What about 8.2.x?
At the moment the write activity is not really responsive when a few
pictures are in the document. I expect that would improve as well.
It looks like abiword 2.8.1 is already part of F11 for XO 1, which
should solve the problem. But I don't expect F11 being installed on the
student XOs very soon, is there an alternative solution like another
activity that can create simple html files with pictures?

Marc Maurer: Impressive AbiWord release
We just released AbiWord 2.7.6, which is an awesome release in my opinion!
It for example adds native JPEG support, so we don’t convert every JPEG
internally to PNG anymore. This will be of great benefit on the OLPC
laptop, where kids use built-in camera to produce photos in JPEG format
and add them to their document. This will greatly reduce the filesize of
their document. It will also be a lot less bandwidth intensive when
collaborating on such a document.

[Server-devel] XS 0.6 on XO
Really nice to have an XS on the XO for testing and showing people what they can do with an XS. The easy setup which doesn't even need an access point is really cool. There are 3 points about XS 0.6 on XO I want to bring up: 1. How to shutdown the XS. I couldn't find the information what is the easiest way to do it. I see to easy options: - Switching off power means the XS shuts down (I have attached an acmon script a workmate wrote some time ago for a webserver on an XO which does that using crontab) - ctrl+alt+delete (on the XO delete is fn+erase) does a reboot at the moment, but I think it could be easily changed to a more useful shutdown. 2. How to change the timezone is missing in the documentation, but probably necessary in most places. 3. Non XO computers can not connect to the school-mesh-0 of the XS on XO. I wanted to do some testing and had just one XO (which was running the XS). To be able to connect from a normal laptop I had to do the following changes on the XS (the specific IP is important since various services are bound to this IP): ifdown lanbond0 iwconfig wmesh0 essid schoolserver iwconfig wmesh0 mode ad-hoc iwconfig wmesh0 channel 6 ifconfig wmesh0 172.18.0.1 Is there an easier way?

sugar-install-bundle doesn't work with content bundles (build 802)
Hi all,
For a deployment without a schoolserver I needed a script to install
bundles (.xo and .xol) from a USB flash drive. I wanted to use the
script for initial installation of bundles, installing upgrades and
reinstall by mistake erased activities. I know the option with the
customization.zip, but I don't want to reboot.
To call sugar-install-bundles in a script seemed to be a good solution:
for i in ${USB_BUNDLES_DIR}/*.xo*; do
sugar-install-bundle $i
done
But I faced to problems:
1. sugar-install-bundle doesn't support installing content/library bundles
2. sugar-install-bundle doesn't support upgrading from an old version of
a bundle to a newer one
So I wrote a version of sugar-install-bundle that solves these two
problems (see attachment).
It is slow, but it works.
Best regards,
Philipp

Re: Create and sign Country specific XO image
The XOs got manufactured some time ago and just not delivered because localization wasn't finished (localization is still not finished, but the XO arrived yesterday). So getting our own keys in the manufacturing data is not an option. I hoped for an easier image creation and signing process. What is the problem with the process described here http://blog.olenepal.org/index.php/archives/183? 1. setup one XO the way you want it (I would use a script to do this) 2. delete a few files 3. create the image with save-nand at the ok prompt. 4. If I could send the CRC file of the image to OLPC and they would give me a fs.zip in return, that would be great. This way I could use the NandBlaster for the first installation and would be much faster than installing os802.img from USB flash drive and call the customization script on the flash drive on each XO.

Looking back, I think this is a better option than image builder for the non-activity customizations, but image builder is probably a bit easier to get started with. You have to decide if you want to sign your own builds, or if you want to get OLPC to do it (if they will do so). To do it yourself you have to generate your own public/private keys and somehow get those public keys to be present in the manufacturing data on all of your laptops.

Re: XO boot problem
Hi Daniel Thanks for the input. The XO is booting fine after the firmware update. I was looking for the bootfw.zip online, older released firmware versions have the bootfw.zip in this directory: http://dev.laptop.org/pub/firmware/q2e18/ But you are right, I can just copy the bootfw.zip from a working XO with build 767 installed. The ticket 7607 got fixed with q2e12 so it shouldn't happen with build 767 (q2e18) anymore. But I got the information that 3 XOs with build 767 had the same problem. They got fixed with a clean install, so no way for further diagnosis.

The solution is to upgrade firmware to e.g. q2e18. While the firmware update will solve the immediate problem where OpenFirmware crashes when minor corruption is encountered, unclean shutdowns will lead to file corruption causing more, probably less-obvious problems down the line.

Re: Journal integration for Scratch
Hi John
Yes, we need the mimetypes.xml file as well (thanks Tomeu I forgot the
USB flash drive use case). I have tested the attached mimetypes.xml. It
is working fine. Put it in the activity directory.
Furthermore we have to change the scratch-activity script, so the
parameter with the scratch project object-id gets converted
(copy-from-journal) in a file and passed on to scratch. See the attached
scratch-activity script. I am not an expert with bash scripts, so please
give feedback.
I would like to extend the script so project files in the journal
directory are copied back to the journal after exiting scratch, but for
opening project it should work fine.
Best regards,
Philipp

Hi, Phillip.
Thanks for all your hard work in tracking this down. I had looked at
several other packages, including EToys, and couldn't figure out from
them how to do this.
I will make these changes to the next XO Scratch bundle.
Is that all I need to do? What about the mime types XML file similar to
the one added by Etoys? Does that turn out to be unnecessary?

Thanks Tomeu to lead me to the /home/olpc/.local directory. However, the
mimetypes.xml is not necessary to get the icon in the journal. I just
had to copy the scratch icon file in the activity directory to
application-x-scratch-project.svg (also in the scratch activity
dirctory). The Memorize Activity is a good example for using that
feature.
Sugar has to be restarted after installing Scratch to show the icon.
John, could you please make the following changes in the next Scratch
version:
- add the line mime_types = application/x-scratch-project to the
activity.info file
- copy the scratch icon to application-x-scratch-project.svg in the
activity directory
Etoys gets configured by different packages. e.g. the rpm
etoys-3.0.2153-1.noarch is adding the file
/usr/share/mime/packges/etoys.xml and the rpm
sugar-artwork-0.82.3-1.olpc3 is
adding the file

Re: XOs with no sound
Happy New Year. We don't use the Measure Activity.

I've checked only the development builds at this stage. Master Mono Playback Switch: is false should be true (line 50) Master Mono Playback Volume: is 0 should be 28 (line 61) These two should have no effect. I've tested that they have no effect on audio playback. The method I used was to temporarily install the OSS module, and run a background process writing noise to the output. Thus: modprobe snd-pcm-oss dd if=/dev/urandom of=/dev/dsp While this is running I then manipulated the controls using alsamixer. The Master Mono Playback controls did nothing. (Incidentally, the volume control keys on the keyboard changed the Master control only, not the Master Mono control, and not the PCM control.) PCM Playback Switch: is false:false should be true:true (line 178) In false:false state, this switch prevents all sound output from activities and applications. The noise test above fell silent. PCM Playback Volume: is 0:0 should be 22:22 (line 190) In 0:0 state, the audio is less loud, but not eliminated. The noise test continued to generate audio, but I needed to set the Master control (not the Master Mono control) to at least 50%. Capture Volume: is 0:0 should be 15:15 (line 287) In this state, the noise test audio is unchanged. This would affect sound capture using microphone though. I hope that helps. Yes, it does. It shows the immediate cause of the problem was that the PCM Playback Switch was turned off. That the Capture control was also changed is interesting. I've searched the installed activities on a development build here for references to the amixer command. The only activity that I've found it used in is Measure. Measure.activity/toolbar_side.py ... changes the Capture control. Measure.activity/audiograb.py ... changes the PCM Playback Switch. Is Measure being used? Can you reproduce the symptom on a working XO by asking for a shutdown while Measure is running? What version of Measure is being used? Version 20 of Measure attempts to restore PCM to 70 on quit. Does the symptom clear if Measure is started and then quit? ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

XOs with no sound
Hi The sound of 5 of our 100 XOs doesn't work anymore. The hardware test is okay (sound works), but all the sugar activities I tested (Scratch, TamTamMini, Speak, Gcompris) don't have sound. Rebooting the XO doesn't help. I checked the sugar log files and /var/log/messages, but couldn't find any sound related warnings or errors. We are running build 767, but I have seen the same problem with build 708 (but not that often). Reinstalling the OS solves the problem, but I would prefer an easier solution. I checked if such a bug is reported, but couldn't find a ticket (the sound resume problem of ticket 6201 is normally solved with a reboot). Since I don't know how to reproduce the problem, I would like to localize it before opening a ticket. What can I do to localize the problem (e.g. low level sound tests)? Is it possible that running out of battery while playing sound can have such an effect or could it be related to the resume problem of ticket 6201 (we had that problem very often with Scratch when the experimental power management was switched on )?

2. Type alsactl -f /media/{flash_dirve_name}/asound.state restore on

cp /etc/asound.state /home/olpc/asound.state.orig

4. restore the settings from the file,
alsactl restore
5. test that sound now works.

Re: Journal integration for Scratch
Hi John Sorry for the late response. I think to increase the font size in the file dialog is a good idea. As for the thumbnails and project notes, for us an easy way to open and save the projects is more important than to see a thumbnail and project notes (the filename and the date when the project was saved is enough information for us). If the examples and the own projects would be separated (e.g. a button examples) would help as well. It is quite confusing for the students that they can not save their projects in some folders (folder symbols of own folders and example folders look the same, but no write permission for the example folders). TurtleArt has such a solution. Scratch is the favourite Activity at our school, even so it is quite hard for the students to drag and drop the small command icons on the XO with the jumping mouse cursor problem. I am aware that these are all just XO problems and you have to maintain other platforms as well. Thanks for your great support for Scratch on the XO. Thanks, Philipp Pepyride School Cambodia John Maloney wrote: Hi, Phillip. Re: Do you plan a journal integration for scratch? Probably not in the near future. There has been talk about making an API for the Journal that looks more like a file system to application programs. That might be the easiest way to integrate the Journal into Scratch in the long run. Sugar continues to evolve. Earlier versions still allowed access to the file system in a way that made it fairly easy to port applications like Scratch. More recently, with the Rainbow security system, it became much more difficult to use the file system directly. I support Scratch on many different platforms. The XO is an important one due to the educational mission of OLPC. Still, my time is limited and I can only spend so much of it on the XO version of Scratch. Thus, I try to steer a middle path -- create a Scratch port for the XO without changing too much of the Scratch source code. I am hoping that eventually Sugar will make life easier for those porting applications from file-based platforms by providing some sort of virtual file system API. The Journal and the virtual file system could just be two views on the same set of files. Re: At the moment it is not possible to delete scratch projects easily (just in terminal) and our students have difficulty to understand the file and folder structure in the dialog with the very small font.

That means the user would not see the project thumbnail and project notes. If project deletion is the only issue, my preference would be to add a way to delete projects to the Scratch open and save dialogs. (Although I'm not promising to do that immediately, since we're currently working on the release of Scratch 1.4.)

At the moment it is not possible to delete scratch projects easily (just in terminal) and our students have difficulty to understand the file and folder structure in the dialog with the very small font. If you don't want to change the core application, there might be a workaround. 1. create a directory projects/journal 2. if scratch gets opened without a datastore reference, a default project (e.g. scratch_project) gets copied to projects/journal and opened. 3. if scratch gets opened with a datastore reference, the files gets copied (copy-from-journal) to the projects/journal directory and opened. 4. the name of the default project still has to be changed with save as 5. after quit the files in the directory projects/journal get copied to the journal (copy-to-journal) and deleted in projects/journal The scratch projects could be erased in the journal. What do you think? One more thing, the scratch icon is not shown in the journal for files with the scratch mimetype.
