Re: [Sugar-devel] Call for Help: SoaS Display Manager (Auto-Login)
Regarding getting auto-login to work after restarting X. Yesterday I looked at the slim sources and it seems at first sight easy to add auto login of the default user after the first login. Any interest in me trying to implement this? If we use an extra option to slim we could push this change upstream to Fedora and then we do not have to maintain our own manager (olpc-dm). But maybe Sebastian is already happy with a working olpc-dm. Ton van Overbeek ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: open80211s
2009/3/7 Rekik Hanen hanenre...@yahoo.fr: Hi, I've been trying to build open80211s on OLPC ( release 8.2.0 ).I have followed the howto at http://www.o11s.org/trac/wiki/HOWTO-0.2.0. However when I run git clone git://o11s.org/open80211s.git and after downloading the packages , I got these errors ( which are represented in the enclosed file scrennshot.png ). Could anyone help me ? thanks If you have the needed development tools (gcc, make, binutils, etc.) installed on the XO then there is not much nand/disk space left. My guess is that you are running out of fllash memory/disk space. What you can do is to put your work/download/build directory on a SD card or an external USB hard disk. That should provide sufficient space for building on the XO. Hope this helps. Bonne chance. Ton van Overbeek ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

In multiVNX the teacher runs the multivnc server and has a summary screen with all the students display (max 16 on a single tab). For this to work each student (multivnc client) also has to run a vnc server on X display 0. They do not use the original Xvnc (which creates a separate X display) but a module in the X server to provide the VNC server functionality for display 0. What I see in your log is the multivnc client trying to configure the VNC server on the same machine and failing. It does this by trying 3 times the 3 flavors of vncconfig, but getting a return code of 127 from the shell executing each command (the 9 print_popen: 127). My guess is that there is no VNC server running on arjs. If the only thing you want is to distribute the teachers screen to all the students then this might be overkill. Your original x11vnc on the teachers Ubuntu based computer might work better. I have done the opposite (x11vnc on the XO, displaying on Windows XP) and this works very well, almost instantaneous screen update. multiVNC certainly looks applicabe in the OLPC environment. Only the teachers computer has to have a larger screen than the XO provides. I'll try to understand better how it is supposed to work.

Re: Updating old 656 qemu image
2008/12/8 Luis Michelena [EMAIL PROTECTED]: I have been working since may with qemu, using the 656 build, made some changes, intalled several packages to make my life a little easier(man, locate, locale, etc) so i'd like to be able to update it in place but I can't: snip ... I tried to update de olpc-update script to the last version, but it didn´t work. By the way, the /versions folder is empty. It seems that that folder should have a link(current) to another directory that contains the version hash, but i couldn't find which value to use? I tried to search snippets of the error log on the net some sensible options but I found none Can you give me some advice? I also downloaded the 708 build, but i didn't found a way to acomplish the update that way either. olpc-update does not work for ext3 images as used by qemu. It is dependent on the flash layout where you can boot from either the current or the previous version. (That is where the /versions/... tree is for). I am not aware of a way to update the qemu image in place. What you could do is to save the /home/olpc tree outside qemu, then replace the image by the one from a more recent build and restore (parts of) your saved /home/olpc tree into the new image. Two caveats: Activities are stored in a different location now (everything under /home/olpc instead of /usr/share/activities and /home/olpc) and activity isolation is now enforced. You need to start from scratch with activities for any recent build: update.1 (8.1, build 703) and 8.2.0 (build 767). Also Update.1 and 8.2.0 are based on fedora 9 and require 3DNow instruction emulation in qemu. A stock qemu 0.9.1 will not be able to boot a fedora 9 based XO image. For windows there is a svn based version which does work. See http://wiki.laptop.org/go/Using_QEMU_on_Windows_XP, especially the remark under Option 2) QEMU Manager for beginners regarding recent builds. Good luck with qemu.

I am not the only one seeing this, Daniel Drake (dsd) complained about this while developing the bridge activity in the physics jam and I have also seen other mails on the list.

It is recommended to use the kqemu accelaratiob module. You'll find a version compatible with this version of qemu in the subdirectory kqemu-1.4.0pre1. Before installing this version, uninstall any previous versions of kqemu ! The kqemu supplied with the released 0.9.1 version is not compatible with this version of qemu. In the kqemu-1.4.0pre1 directory right click kqemu.inf and select Install. See also http://bellard.org/qemu/kqemu-doc.html . The service can be started by the command 'net start kqemu'. it should report The KQEMU virtualisation module for QEMU service was started successfully. on Win XP/SP2 Running qemu Make sure the kqemu accelerator is running (see above). To run qemu for an XO-1 image use commands like: -- net start kqemu qemu -L . -cpu athlon -m 512 -net nic,model=rtl8139 -soundhw es1370 xo-1-olpc-stream-8.2-763-devel_ext3.img -- The important option is '-cpu athlon'.

Gabriel Eirea wrote: Hi list, I'm having a hard time trying to test an activity in 8.2 using qemu. The activity (Conozco Uruguay) doesn't work in 8.2 although it works fine in previous versions. We suspect it is related to rainbow (trac #8334). Since there is little documentation on rainbow (I still don't know what it is and why including it broke the activity) I'm going to follow a hack suggested by brian. The thing is, I can't make builds 759 nor 760 run using qemu. The configuration is fine because I can run build 659. In 759 it stops when saying Booting from Hard Drive... and in 760 it says that the kernel needs 3dnow. I downloaded the images from http://pilgrim.laptop.org/~pilgrim/xo-1/streams/8.2/ Has anyone tested the images with qemu? Can anyone suggest how to proceed? I'm very interested in making my activity work in 8.2! There are/were two problems. The first one (8.2 image not booting at all) has been solved with 8.2-760. The second one (3DNow required) is due to the change to the 2.6.25 kernel for 8.2. The kernel checks for CPU features and does not continue booting when it does not find them. The kernel for the XO is build for the AMD LX-Geode and therefore looks for 3DNow. If you would run qemu on a machine with an AMD processor it most likely will work. If you are running it on an Intel processor, you get the kernel needs 3dnow message. See also trac #8369 (http://dev.laptop.org/ticket/8369). In the CVS version of qemu you can specify a cpu type (use -cpu=athlon for the XO) and then you can run 8.2 and recent joyride devel-ext3 images in qemu on an Intel based machine. I have a privately compiled version which runs under Windows XP (have not tried it under Vista). Let me know if you are interested in this one and I can send it to you. If you are using Linux you will have to compile your own qemu. There have been some efforts to get a qemu specific image not requiring 3DNow next to the existing ext3 images (since the existing ext3 images have to be able to run on a real XO when booted from USB or SD) but so far this has not been realized.

(note the trailing dot) for the localized files (.mo and fonts). I believe this was fixed when I checked in some Makefile changes. I have not rebuilt the *.xo since I fixed the Makefile. I could not get your Makefile fix to work. The code still looked for localization information in ../TuxPaint.activity. (with trailing dot) due to the DEFS definition in the Makefile. See my changes to the olpc: target in tuxpaint/Makefile (explicit defintion of LOCALE_PREFIX). BTW, perhaps I'm being too picky, but I'm trying to get Tux Paint sources in CVS to support building a *.xo with one command and a minimum of hacks. This is a good part of the reason for the delay. TuxPaint-1.xo is not very reproducable; plenty of manual work was required to create it. I have followed your example and to build my version start in TuxPaint.activity/ and then do 'make olpc'. See TuxPaint.activity/Makefile and tuxpaint/Makefile. This assumes you are building on an XO (see also below). - Added the needed libpaper.so in the bundle and modified sugarize.c to add LD_LIBRARY_PATH so tuxpaint can find the library. I didn't do that for several reasons: 1. license issues 2. version control issues 3. can't set up /etc with the right printer info If libpaper isn't in the base system, then I don't want to use it. I have two other choices. I can rip out printing. I can revert to some older code which directly generates postscript. Assuming that printing support is even desirable, reverting to the old code (plus bug fix) looks best. That way, there is little need to worry about paper sizes. Agree with your reasoning. For the XO it is probably best to disable the priuter support completely. The current code requires libpaper and I did not want to remove the printer support code, since I am not that familiar with the TuxPaint code (yet). Hence, the easy way out was to include libpaper.so in the bundle. Since it is available as fedora-9 rpm I did not expect any license issues for libpaper. Other changes: - Added support for svg (scalable vector graphics) stamps. Which library? Which *-devel packages must be installed? All the non-devel rpms/packages needed for svg support are already on the XO (at least for Update.1 and the current joyride/8.2 builds). I needed the required SDL-* devel rpms anyway to compile so 'it just worked'. My build machine is a QEMU emulated XO on Windows XP/SP2 with an extra 1GB disk where I moved and mounted /home/olpc to make room for all the needed devel packages and gcc, make etc. In the most recent builds also SDL-pango is included, as you know, so now we should be able to build a full TuxPaint, but only for 8.2 systems. SDL-pango is not available on 8.1 and older builds. - To save space, keep only the smallest version of a stamp if both svg and png versions are available. - Removed development related files in the bundle. The full source is in TuxPaint-2.xo.tar.bz2. This really should happen in the main Makefile, via not copying them in the first place. Agreed, but I did not want to mess with the install-all target in tuxpaint-stamps, since that is used by everybody, hence the use of some cleanup scripts. See TuxPaint.activity/Makefile. - Updated activity.info with license information

Filed trac ticket 8369 about this issue. Here is the text: == All 8.2 devel-ext3 builds are unusable in qemu with the lone exception of 8.2-751.

Problem on both 8.2 and joyride is the missing grub stage1 loader.

The lack of recalibration messages in 708 does not mean that the cursor isn't messed up. When you boot and use 708, is the mouse cursor jumpy at all? No, under 708 I get no noticeable cursor jumps. There is a lot of strangeness in your 2298 logs. The fact that 3/5 times, the driver detects miscalibration at around the same time (160s after boot) makes me wonder what's happening there. What point in the boot sequence are you at when it happens? Is sugar completely up? Are you launching any activities, or doing anything else other than moving the cursor around? When booting I wait till the home view is complete (circle view with activities) without touching the touchpad. Then I start a terminal session and start Memorize. Memorize requires a lot of mouse movement. Play a while in Memorize until the cursor starts jumping. Then switch to Bounce and play a while. At 160 sec I am in Memorize. The eth0/msh0 messages makes me think that NetworkManager has just come up, so the hardware was miscalibrated right from the start. I wonder if the large amount of EC commands happening during boot are screwing something up.. I'm also wondering wtf the PCI EHCI messages are about. The EHCI messages only started to show up with the most recent kernels. I cannot give you a specific date/version. Sorry. Also I am in a quite noisy WiFi environment at home. There are more than 15 WiFi networks in the neighborhood view. My home accesspoint has WPA-PSK. Sometimes the XO prompts me for the accesspoint password. I cancel the dialog and then go to the neighborhood view, select my network, click Connect again and it associates without prompting for the password again. Might have nothing to do with this. Do you keep your finger on the touchpad during bootup? Also, when you see the miscalibration errors in the logs (and you remove your fingers from the touchpad for a few seconds), does the touchpad driver fix itself, or is the cursor still jumpy afterwards? As written above, no finger on the touchpad during boot. After recalibration it fixes itself for a short while, but then starts jumping again (as you can see in the logs). Saw Richard Smiths message about the new firmware with faster/better EC handling. My XO firmware is on Q2E12. Could the interaction between recent firmwares (Q2E12) and 2.6.25 kernel scheduling have something to do with this? Should I try again when Q2E13 shows up in joyride? ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Back to the subject in the subject line (next build delayed). The joyride-2303 build failed because koji.fedoraproject.org timed out. I tried the site directly in the browser and it is indeed very slow and I also get time-outs. Something going on at RedHat? DDOS attack??

Problems switching back from joyride-2290 to Update.1-708 (rainbow). Help wanted.
For my testing for trac #7788 I want to switch from Update.1 to joyride-2298 and vice versa (using alternate boot). After switching back from joyride-2298 to Update.1 most activities do not start because their home directory does not exist. I need some pointers where to look in rainbow how to get this two way switching working. Anything I can run in Update.1 or rpm to update to get this working ??? One thing I noticed is that /etc/group does not have all the groupids in Update.1 but I have no idea how they got there in the first place.

At least it does not show up in the dmesg output. - More important, the touchpad seems to behave much better. May be related to the reduced polling of the EC. That makes sense if previously you were seeing jumpy touchpad behavior every 30 seconds or so. During EC command processing the kernel disables interrupts which means that you won't be responding to data from the touchpad. The update rate for the touchpad is 12ms so if you hang out for longer than 12 ms we think you lose motion data. I don't know how deep the buffer is on the touchpad but it does not seem to be very deep. The EC only buffers a single byte. I might have spoken too soon. Yesterday the touchpad jumping was back in joyride-2280. In my initial run of joyride-2280 the battery was full and the XO was connected to the mains power. This time I was on the battery and the battery was running down. In dmesg I noted a lot of EC traffic approximately every 2 minutes. Does the frequency of EC polling increase when the battery runs down? Also in the touchpad recalibration messages I see a lot of nested calibration requests: several other calibration queued while performing one. This does not seem right to me. Again, Update.1 (build 708) behaves much better. For me personally this (the touchpad problem) is the biggest show stopper for 8.2.0 !!!

Tried your test for 2866. Works as advertised for me (joyride-2280). Could not test the mesh, since I have only one XO. At startup, when showing the frame, you see first the attempt to connect to the mesh, then it is replaced by the AP icon and information. I like the signal strength indication and the IP address.

The problem was that a Fedora 9 update included an updated evdev driver, which had been compiled against a newer X server (we have forked xserver, so we don't automatically get updates there). I have resynced our xserver with Fedora's so we support the new ABI which evdev uses. Resyncing the X server was not quite as simple as you might expect. Previously, X was compiled along with the mesa sources to offer software-based GL. The software GL is very slow but word on the street is that some activities use it anyway. In the newer X server, the software GL implementation (dri_swrast) has been moved to mesa, which we don't include in our builds. The newer X server also includes a bug which caused it to crash when no swrast was present, I wrote a patch included in our build which I will be committing to freedesktop git upstream shortly... Anyway, at the moment, we have no swrast in our build, which means no GL support at all. Does anyone care? I am going to work with Fedora to get the swrast module separated from the overweight mesa-dri-drivers - this could return in future if we need it.

Something wrong with /dev or /sysroot in the ram disk
I'll try the next joyride (2205 ?) too.
My firmware is now Q2E11 (got updated during one of these tests when my
xo-1 was on net power)

Can you try with the updated olpcrd at the same URL? We're also missing
sg.ko. I've added it to the ramdisk along with the changes to load it.
If this works for you, we'll push into another build.
The 5 seconds is b/c we sleep to give disks time to spin up.
Thanks,
~Deepak
Tried with your version of 14:57 (2720066 bytes). Same result. Same
messages, still failure to mount /dev/sda1.
Apologies for the disappointing result. Do we need more/other scsi
modules? Can we get more debug info from mount?

Cannot boot joyride-2200 from USB stick
Hello,
My xo-1 is currently on build 708.
For testing joyride-2200 I did not want to reflash yet, but boot from a
USB stick instead.
So I downloaded the image from
http://xs-dev.laptop.org/~cscott/xo-1/streams/joyride/build2200/devel_ext3/xo-1-olpc-stream-joyride-devel_ext3.img.bz2,
unzipped it and copied it to a 1 GB Sandisk USB stick.
Booting with extended messages (X game key pressed) shows that OFW finds
my developer key
in the main flash, finds the OS on the USB, does not update the firmware
(no external power)
and then loads the ramdisk.
Booting starts, but mounting /dev/sda1 on /sysroot fails because the
usbcore.ko module
needed by usb-storage.ko cannot be found.
Some of the messages are (copying manually from the xo-1 screen and
skipping the stack depth messages):
--
FATAL: Error inserting usb-storage
(/lib/modules/2.6.25-20080722.2.olpc.d86980aeb8d0adb/kernel/drivers/usb/storage/usb-storage.ko):

mount: mounting /dev/sda1 on /sysroot failed: No such device or address
Traceback (most recent call last):
File /init, line 131, in module

File /antitheft.py, line 31, in run
return run_init_callback()
File */init, line 103, in run_init

raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['/bin/mount, '-n', '-o', 'ro',
'/dev/sda1', '/sysroot']' returned non-zero exit status 255
Is this (booting from USB) supposed to work? Has it ever worked?
Or am I missing something?
It seems that usbcore.ko has to be available early in the boot, but
cannot be found.
Any hints on how to proceed, or instructions on providing more data are
appreciated.
Regards and hoping to be able to test joyride-2200 soon.

Joyride on qemu (was:Write needs your help)
Edward Cherlin wrote: I'll install joyride in qemu when 2.6.4 is ready and give it a go. Remind me when the time comes If you are not on a machine with 3dnow support you cannot run any fedora core 9 based joyride build on qemu (unless you rebuild qemu from the trunk of the subversion archive).

I'm running Os X Leopard and want to use qemu to emulate the os and start developing. However I'm getting problems. I'm following the directions here: http://wiki.laptop.org/go/OS_images#Latest_Stable_Build and got my image from here: http://xs-dev.laptop.org/~cscott/xo-1/streams/joyride/latest/devel_ext3/ When I try to boot the image, the kernel complains about 3dnow not being present in the cpu(which is not emulated with Q in macs), and I don't know what to do now from here. Me too. Fortunally I have 2 machine: one laptop with intel and a desktop with AMD so I use the desktop for my test. I already ask about this problem but seems that at the moment only one kernel is build with 3dnow extension enabled. I hope for the next build. Any suggestions? Personally I install a FC9 on my virtualizzazione system and build all the sugar environment to make my test. You can use this way but it is right only if you want develop for XO (I suppose). I am running into the same problem. This is caused by a change in the linux kernel boot code sine 2.6.24 (?, not sure of exact version, but somewhere between 2.6.22 used in FC7 and 2.6.25 used in FC9). In 2.6.25 the boot code checks for CPU features and bails out if it does not find them. In the SVN version of qemu there is already a patch to provide 3dnow instructions when you select cpu type athlon. I am planning on backporting this to qemu 0.9.1 and try it out. The current svn version of qemu also requires a rebuild of kqemu due to an API change introduced at the end of May. Hence my idea of backporting the patch to 0.9.1 to avoid to rebuild kqemu (I am on Win XP/SP2). I'll keep the list posted on my qemu attempts ...

Cannot test 8.2 images with VMware Player on an Intel laptop (Kernel requires 3dnow)
Hello, I am trying to run the 8.2 builds under VMWare Player on my Windows XP Intel laptop. The 8.2 image I used is from http://pilgrim.laptop.org/~pilgrim/olpc/streams/8.2/build3/devel_ext3: xo-1-olpc-stream-8.2-devel_ext3.img.bz2 Converted with qemu-img to a vmdk as per the instructions on http://wiki.laptop.org/go/VMware/Convert. At boot I get the message: This kernel requires the following features not present on the CPU: 3dnow Unable to boot - please use a kernel appropriate for your CPU. The same procedure worked without any problems for update.1 build 708 (aka 8.1.1). I suppose this is caused by the switch from fc7 to fc9. Any chance of generating devel images with a kernel which does boot on Intel (non AMD) CPUs? If not, any hints on how to replace the kernel image in an ext3 devel image with a custom built one? I use this setup also to test/try collaboration between my real G1G1 XO and one or more emulated XOs on my laptop, all on the same local network. Many thanks in advance for any hints.
