new F11-for-XO1 images available for testing
by Daniel Drake 02 Nov '09

02 Nov '09

Hi, I just built 2 images of F11-for-XO1 on OLPC infrastructure according to my own instructions. http://wiki.laptop.org/go/F11_for_XO-1 The first one is based on the backport that I built and tested before (a few weeks ago), so it will probably work: http://dev.laptop.org/~dsd/f11-xo1/os1 and the second one is updated with all of the recent changes that have been happening in XO-1.5 software development, bringing the 2 trees in sync at the present time http://dev.laptop.org/~dsd/f11-xo1/os2 Neither have been tested since the internet connection here in Nepal is very slow - I will download them over the weekend. It would be great if anyone is interested in testing during that time though. I would suggest starting with os2 and falling back on os1 if it doesn't work. I'm still looking for people to take on the role of making these builds on a regular basis - for me, these builds are just a one-off for now. The usual cautions apply: this is development code, there will be bugs. Installation instructions: use copy-nand to install osX.img with osX.crc. Daniel

soas04xo behavior on XO-1
by Mikus Grinbergs 31 Oct '09

31 Oct '09

I'm booting soas04xo from nand on an XO-1. For me, alt-tab does not work to switch between activity sessions - I have to use the icons in Frame top right to switch between Activities. But I've customized my system, so I don't know if this is a sugar problem, or my problem. Please, would someone try soas04xo and see if alt-tab works for him? Thanks, mikus

The reason for this is that Xv scales YUV data and Flash uses RGB data. Now could this be converted and scaled absolutely, but Adobe has decided they are not going down that road. My guess as to the minor release performance slow down, is that the linux flash player gained Mpeg-4 video support in that release. H.264 is much more processor intensive and would explain the performance problems seen after the upgrade. This same release was also the first release that supported the Xembed protocol. Some inefficiency there could also have created the video performance problem. Hope that helps to clear up the playing field. Jon

Changing the 'Depth' in "Screen" in /etc/X11/xorg.conf did not cause the "playing movies locks the system" problem to go away. > General comment on the typical "have you logged this?" response we tend > to get ...

I think poor "moving pictures" is __the__ problem with the XO-1.5. Therefore I'm willing to put effort into documenting that which is happening (and into testing fixes, if someone were kind enough to give me something I can try). But this is a hang - which leaves the XO-1.5 completely unresponsive to operator input (except for the power button). So I do not have my normal opportunity to capture file contents, etc. They are wiped out by the reboot I perform to access the system again. I think Martin mentioned he was able to get in to the hung system with SSH. I have basically never used SSH -- so I would have to do a lot of learning before I could use that to obtain better information than I have now (I wrote all I knew in my post). mikus

> YouTube video can be encapsulated H.264, On2 VP6, or the older > Sorenson Spark. So it's important to try to test the same file. Where you are coming from appears to differ from where I am coming from. I am looking at the XO from the point of view of "How usable is this?" That question does not necessarily involve precise measurement -- evaluation ought to suffice. In my mind I did not volunteer to be a formal "tester". If you want me to be, please publish a formal *specification* consisting of 'shalls' -- i.e., the XO __shall__ properly render H.264 videos, the XO __shall__ without visual aberrations play back videos using an on-screen picture size of at least 14.67 cm by 11 cm, etc., etc. *Then* I will develop a "test suite", which I will run against every new beta that comes along (to "check off" which 'shalls' are being met). mikus

os33 - video regression ?
by Mikus Grinbergs 26 Oct '09

26 Oct '09

When I try to run mplayer on os33 with the parameters that I use on the XO-1, the XO-1.5 shows a bright green screen and locks up completely (all that I can do is power off). I have to explicitly tell mplayer to use the 'x11' driver (i.e., *no* implied acceleration) in order to see a "moving picture" in os33 with mplayer. [IIRC, previously on os32 my mplayer with the XO-1 parameters had worked, but jerkily.] Also, though it may be a function of network congestion / source quality, but my impression is that with os33 YouTube is "jerkier" than I remember from os32. mikus

PolicyKit dependency chain for headless machines
by Martin Langhoff 25 Oct '09

25 Oct '09

Working on the OLPC XS rebase to F11 -- I end up with random bits of gnome and kde, brought in by PolicyKit, which wants a PolicyKit-authentication-agent. Yum only seems to know of KDE and Gnome authentication-agents. How does PK handle users logging in in a VT? What is the authentication agent there? cheers, m -- martin.langhoff(a)gmail.com martin(a)laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff

F11 wired vs. jabber
by Mikus Grinbergs 22 Oct '09

22 Oct '09

I don't have wireless (i.e., no AP), but use a local ethernet LAN. When I boot a F11 system, usually Neighborhood View shows me the (running) XOs connected to my ethernet. But sometimes what I see is the XOs connected to the Jabber server I have defined. To reach that Jabber server, the connection has to go over the ethernet, through a proxy (I had to tell telepathy that the proxy exists), and then over the internet. [I am leaving the Jabber server name in 'My Settings' -- I am not adding/removing it dynamically.] Which set of XOs I get to see seems to be random. [Still happens that way both on XO-1 and on XO-1.5.] Any ideas on how, with my setup, I could "favor" seeing jabber over seeing wired ? Thanks, mikus
