(hit sent too soon)
I did some XO1.0 testing with 802 B1 yesterday and today. First I:
- updated firmware to q2e41 (latest)
- updated to 802 b1 from USB:
- probe-usb copy-nand u:\xo1.0\os802b1.img

Note! We are also testing the XO-1.5 builds, and hoping to make a
release Real Soon Now. If you have XO-1.5 hardware, help us test the
1.5 builds. On the other hand, if you have XO-1s to test, I need help
The build is '802B1' -- find it at:
Filing bugs -- the bugs related to this release are tagged with
milestone '8.2.2'. Please set that milestone in any new bug you file,
or add your notes to the existing bugs:
The build has a rebuilt kernel with new touchpad drivers, and some
configuration tweaks. This is for both old 'ALPS' touchpads and new
'Synaptics' touchpads. (Do mention which one you have!)
With these changes, the touchpads should move a little bit slower,
have a bit more precision, and be a lot less 'jumpy'. In fact, when
they data gets jumpy, the driver ignores the data instead of jumping
Is the kangaroo mode gone? Is it more usable now? Are other effects creeping
I have ALPS touchpad.
The mouse movement is perhaps a bit less jumpy then in old 802, but
overall not very useable. There are times when it's ok (just slower
then on the default 802 version), but there are times when it stops
almost completely to respond to moving finger. Sometimes it has to be
nudged 10 times to move the width or height of the screen. I cannot
really tell why it is ok and why it starts behave like that. It comes
and goes. Several times it moved slowly by itself. In a way it appears
better when I do a continuos line draw (like when drawing spirals),
but when using it in an application (does not seem to matter which
app), and move the mouse quite a bit, it starts exhibit the no
Comparison test drawing spirals:
- Grab 2 XOs with the same touchpad type, load the old stable 802 on
one, and my test build (802B1) on the other. If you only have one XO,
try one OS after the other...
- Open Paint and draw spirals
1) try to keep it reasonably tight
2) stop if you collide or get sloppy
3) count the number of cycles
4) try again N times
5) use the average cycles as a measure
well, I only have one XO 1 and did not go back to old 802. With 802b1,
I typically managed to do about 5 spiral cycles before it drew into
the previous line. But after changing brush size I got a completely
unpredictable behavior (non-responding or jumpy)
I can also tell that the right part of the pad is much less sensitive
(going up and down on the right does not move the mouse), this seems a
hardware issue i wonder what others see.
Overall I think the old 802 cursor behaved a bit better, but I really
need to go back to it and try again. It is hard to compare without
having them side by side.
= Kernel =
The kernel rebuild may have caused other issues. Any problems with
suspend/resume, wireless, freezes, I want to hear about them.
This seems to work with no problems:
10sec wait , several minute wait, about 15 minute wait
activity came back.
closed lid several times in quick order
activity came back when opened and mouse moved.
= Wireless: Associating to Access Points and debugging =
Fixed a bug where NetworkManager would -- in a % of connections -- not
realise that the process had succeeded. Side by side, 802B1 should
connect successfully to an AP more often.
And now if you `touch /etc/NetworkManager/log-supplicant` and restart.
That same file is used as the logfile by wpa_supplicant.
= Startup / shutdown =
Two bugs related to the shutdown process have been fixed. Rebooting
side-by-side, you should see 802B1 shutdown much faster, and never
hang in the switch to the ul-warning screen.
If it ever hangs in the shutdown process, let me know...
= Talk to the XS =
Sugar now connects to gabble immediately after registration, no need
for a reboot - If you have an XS handy (hint: get the XS-on-XO image
on an SD card!), you can confirm this enhancement.
You can run 'olpc-connections' in a terminal to see it switch from one
to the other right away.
= OS version =
The Sugar Control Panel should report the right version in 'About my
XO'. And the 'Update' control panel must check for new activities by
hitting a url ending in /8.2.2 (you might
