package review needed for olpc-kbdshim
by Paul Fox 03 Jun '09

03 Jun '09

i'd like to get olpc-kbdshim upstreamed so that more people can try it, etc. https://bugzilla.redhat.com/show_bug.cgi?id=495902 if anyone can do me the honor of taking a look, and gently telling me all that i've done wrong, or not at all, i'd appreciate it. (i'll be submitting olpc-powerd for review as well, but since i've surely made the same mistakes in both, and olpc-kbdshim is independent of olpc-powerd, i'm doing it first...) thanks! paul =--------------------- paul fox, pgf(a)laptop.org

Please update your Sugar packages for SoaS!
by Sebastian Dziallas 03 Jun '09

03 Jun '09

Hi all, as we're quite quickly approaching the next release of SoaS, which is scheduled for June 24, it would be great if you could update the Sugar packages you maintain in Fedora to their latest versions. The whole roadmap is listed on our wiki, where you can also find the current version number of your package(s): http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Roadmap#Packaging In case you're unable to do the update, you can drop Steven (listed as CC) an e-mail, who has kindly agreed to help, if needed. Thanks a lot, --Sebastian

Daily builds are no longer livecd images
by Chris Ball 31 May '09

31 May '09

Hi, Starting with today's 20090525 build, the images are no longer livecd images, so changes will persist across reboots. http://dev.laptop.org/~cjb/rawhide-xo/20090525/ (The sporadic "creating devices" mount hang will still be present for jffs2; there's no need to report that again.) Thanks to Sebastian for the script to make installed images! - Chris. -- Chris Ball <cjb(a)laptop.org>

Thank you, thank you. Finally, I'm able to see that changes will "persist" after the reboot of an XO, which was booted off an USB stick. It was a long struggle to get this working - but with the help of the participants on the fedora-olpc-list it ended successfully. Thanks: Chris, Mathieu, Jerry, everyone. mikus

Thank you. I added the "--overlay-size-mb <size>" to the script invocation, so it now is: 'livecd-iso-to-disk.sh --format --overlay-size-mb 600 --xo --xo-no-home /media/disk/20090519.iso /dev/sdf1'. That caused additional file '/LiveOS/overlay-LIVE-AA00-0383' to be allocated on the USB stick when its content was being built. [But note that when I run 'livecd-iso-to-disk' on my Ubuntu 9.04 (Jaunty) system (with latest kernel released by Ubuntu), I'm still getting the error: "running kernel cannot mount the squashfs from the ISO file to extract it. The compressed squashfs will be copied to the USB stick."] When I booted the XO using that USB stick; made system changes; shutdown; powered off; rebooted with the USB stick -- the changes I had made had "evaporated". ---- What can I do to make my changes "persistent" when booting an XO from an USB stick ? [It is not realistic for me to acquire a Fedora desktop system to run 'livecd-iso-to-disk'.] Thanks, mikus p.s. On the USB stick, in the file '/boot/olpc.fth' (generated by 'livecd-iso-to-disk'), the line that sets up the boot parameters specifies: 'reset_overlay'. What does 'reset_overlay' as a parameter do ? Should it be there ?

Yes. If I remember correctly, this has happened with every rawhide-xo build ever released. [It also happens with Soas2.] mikus

Just tried it with rawhide-xo 20090528.iso (installed on nand): Pressing the Fn key generates an '=' character at the text cursor. [I normally use an external USB keyboard with my XO, to avoid this unwanted Fn key behavior.] mikus

rawhide-xo 20090528
by Mikus Grinbergs 29 May '09

29 May '09

Using 'copy-nand', flashed ~cjb/rawhide-xo 20090528.img to XO nand. My experience with rawhide-xo 20090528 matches that with 20090525. One significant fix that first showed up in 20090525 is that the OLPC keyboard (e.g., the Frame key) is now being recognized. One problem that showed up in 20090525 is that Sugar does not pick up on the 'Desktop' font size specification set within Gnome. The result is that labels (e.g., in My Settings) are now really tiny. A bigger problem, which I first noticed with 20090525, is that Neighborhood View is empty (except for the 'me' icon in the middle). [In contrast, my rawhide-xo 20090519 system's Neighborhood View shows both existing wireless access points and existing wired XOs.] mikus

Ran 'livecd-iso-to-disk' with Soas2-200905241902.iso to create a bootable USB stick. Then booted my XO from that stick. The labels in 'My Settings' using Soas2-20090524 are equally tiny as those same labels using rawhide-xo 20090528. So is the default text in 'Terminal' (in Sugar). mikus

This no longer happens, so if you (for example): > > # touch /foo > # touch /etc/bar > # reboot > > The files will still be there after reboot. I *still* do not understand why that should be so. The only machines available for me to experiment with are XO-1s. The above-described scenario does NOT work for me. -------- I did the zcat 20090525.bootable.gz > /dev/sdf1 (USB stick). That USB stick failed to boot on the XO. The messages from OFW were "Error: Unknown file system Can't open disk label package" Then I did the livecd-iso-to-disk.sh 20090525.iso > /dev/sdf1 (USB stick). That USB stick booted fine on the XO. Made some changes to the root filesystem, and rebooted. After the XO had completed rebooting (in the process, it reloaded its root filesystem from the USB stick), the changes I had previously made were NOT there. -------- I can understand how changes made to the "recording medium" will be there after a reboot. [For instance, if I boot from nand, then make changes to the filesystem in memory (and the system writes those changed memory pages back out to nand), then when I reboot (from nand) the changes will still be there.] But in the case of booting from an USB stick, I believe the system does *not* write the contents of changed memory pages back out to the USB stick. When I reboot from that USB stick (particularly if I've powered-down the system in the meantime), why would the changes still be there ?? Thanks, mikus
