Re: F11-0.88 os260py
Yes, I talked about automatic suspend. However the WLAN was not connected to any access points and it seems that Bernie talked about dropped wireless connections in the release notes as far as I know.

Re: F11-0.88 os260py
I have just installed it onto my XO-1 (C1 model with the old style touchpad) without anything plugged into it. It seems to work but the suspend/resume is "interesting". Sometimes it goes to suspend but after that I cannot wake it up except with the screen rotation button. I press the button and the XO draws a lot of rotated images (10-20) and then it stops. After this I can wake up the laptop when it suspends again by the touchpad or keyboard. What is interesting is that sometimes when it wakes up the screen backlight dims for a fraction of the second. Is it the normal behavior? I mean it seems that the hardware suspended before the backlight could be dimmed. What is the expected behavior? Another strange thing is that when I use Read to read a pdf file and rotate the screen 90 degree then the top of the screen (toolbar) gets black or garbage and when I move the mouse cursor over that area it redraws the toolbar with some garbage. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Excerpts from Bernie Innocenti's message of Fri Jun 18 03:26:56 + 2010: > * Disconnects from network on power save. This is a long-standing >kernel bug. In 0.84, we "fixed" it by disabling power management. I'm not sure what you're seeing is really a kernel bug (unless you don't ship the latest OLPC kernel). It works fine for me even across several hundred suspend/resume cycles (it gets woken about once per 1-2 minutes by IGMP queries from the AP), though this is with an otherwise unused WLAN, so rekeyings are infrequent. And rekeyings might be exactly what's causing you trouble: According to Dan Williams, the libertas chip doesn't wake us for these [1]. I haven't had time to verify that yet. Upgrading to the latest NetworkManager version might also improve things a lot.

Excellent integration work! Before, it used to be the upstream
developers who had to also debug on Fedora and sometimes on other
distros, and as you said, it often takes a lot of time.
It's great that this work has moved downstream!

If you can reproduce it, it would be great to gather some profile data
during activity launch with this:
## Before launching ##
profiler = cProfile.Profile()
profiler.enable()
## After launch ##
profiler.disable()
profiler.dump_stats('/tmp/profile')
It should tell what's Sugar up to.

F11-0.88 os260py
This is the an interim release of Sugar 0.88 + GNOME series for XO-1. Please refer to this page for the current status and download instructions: http://wiki.sugarlabs.org/go/Deployment_Team/Sugar-0.88 With this build, all the major regression relative to 0.84 are fixed. The switch to Metacity resulted in a few hard issues on Fedora 11. There are still several smaller bugs to work on. All the new features planned for this cycle are now merged, with the notable exception of collections support for the activity updater, which urgently needs a volunteer. At this point, it seems too late for the much anticipated resurrection of Rainbow. Maybe next time. There may still be time to merge and stabilize a couple of minor features, such as a button in the Network control panel to re-register with the schoolserver. == Changes relative to the previous release (os258py) == * Integrate journal backup and restore to USB (esteban, tch) * Integrate function for mounting a GNOME Documents folder in the journal. Still presents some rough edges. (jasg) * Pull latest OS updates from upstream (fedora) == Bugs fixed in this release == * Make ALT-TAB work. It was caused by a bug with XUngrabKey() in the old Xorg server of Fedora 11, but we worked it around in Metacity. We spent a lot of time to figure it out!
