Jim/anyone else,
I was finalizing our custom Ubermix image that we will be using for our Cedar Trail devices. Everything was working wonderfully on the base machine so I captured it. When I applied the freshly captured image to another 1011CX strange things happened. Firstly, the power icon that is driven by the indicator-power package appears then disappears constantly, but only when plugged into power. When on battery it functions as expected. As soon as a power adapter touches the machine the icon will disappear, only to re-appear a second or two later. It continues this until you unplug it.
The other issue we are seeing is with wireless connectivity. My base machine was able to connect to our two SSID's we have in our district without a problem. The test machine is not able to connect to whatever wireless I had as default. It will connect to the other network without a problem though.
Ideas?

If you are running a version prior to 1.03, there was a bug that made the wireless settings non-portable. To fix it, follow the instructions on http://wiki.ubermix.org/page/Manual_Updates under the "v1.03 Updates" section.
Not sure on the battery indicator, but would guess that it has something to do with the way it is tracking battery history. Does it get any better after a reboot?
-
Jim,
I'm using 1.03 but also tried 1.04.
It doesn't get any better after rebooting. I even tried to remove and reinstall through package manager. It's the strangest thing.
What's even funiier is that I downloaded a fresh 1.04 from the site and applied it to a fresh, never touched machine. Same issue.
-
I'm thinking maybe this is a BIOS issue. Are the BIOS versions on the good one and the troubled ones the same?
-
Just posted a 1.05 release with quite a bit newer kernel and drivers. Didn't experience the issue on my 1011cx with the new version.
-
I'll give 1.05 a try tomorrow and see what I come across. I haven't compared the BIOS versions either, so I'll check that out. Thanks for all you do!

Jim, 1.05 seemed to work better on the machine. Is there a way I can update the kernel on the 1.03 build without loosing the custom boot menu?
-
Yes, download the following 2 files on your master machine:
https://docs.google.com/open?id=0B52M_cKAX2AROC1Jbl9Famg2c2c
https://docs.google.com/open?id=0B52M_cKAX2ARNUs5b3VhQXd4Mk0
Then do the following:
- Reboot in generic mode
- Open a terminal and type the following commands:
sudo dpkg --purge linux-image* linux-headers*
sudo dpkg -i Downloads/linux-image* Downloads/linux-headers* - Reboot
If you do that and everything on the http://wiki.ubermix.org/page/Manual_Updates page it will get you close to 1.05.
-
Jim, that worked wonderfully. Ran both commands in order, rebooted and everything is working as expected. Thanks for all you do!

Hey Jim, another issue...Since I did the kernel update I am no longer able to port the wireless from one device to another. It says that connections are available but will not auto connect to the wireless captured in the image. When looking at the "Edit Connections" on the WLAN is has a mac address in that field that isn't from the imaged device, but from the captured device. I checked the sudo gedit /usr/local/bin/home_prep.sh and the line "sed -i 's/mac-address.*$//g' /etc/NetworkManager/system-connections/*" is listed there right above done. Any thoughts?
Could this be an issues of Broadcom to Atheros? My base captured device has an Atheos card and the imaged devices have a Broadcom card. Both are N2600 CT devices...
-
Hmm. The wireless adapter brand has nothing to do with it, so something must be going wrong when the home_prep runs. Unfortunately I'm not able to recreate the problem here - is working for me. Worse case scenario you could always boot in generic mode and run the command manually by inserting a "sudo" in front of it, like so:
sudo sed -i 's/mac-address.*$//g' /etc/NetworkManager/system-connections/*
Then verify that it worked with a
sudo cat /etc/NetworkManager/system-connections/*
As long as there is no mac-address line, the settings should work on any machine.
