Manual Updates

This page is primarily for customizers and those managing large deployments who wish to solve minor ubermix problems without having to rebuild their image files. It outlines the steps you can take to manually update an existing ubermix install, in order to gain some of the updates of a more current release. Please bear in mind that this page only includes updates that are reasonable to perform. Major updates (like newer kernels) will likely require a full upgrade. DO NOT apply older updates to newer versions or you will likely break something. Also, do not jump major releases - 1.x updates probably won't work on 0.9x versions.

v1.04 Updates

Switching to/adding to the Broadcom STA Driver

v1.04 re-introduced the Broadcom STA driver, which works with a broader range of Broadcom cards and solves some minor bugs. To install it on a

1. Download bcmwl.tar.gz on the device you wish to update
2. Double-click, the bcmwl.tar.gz file in your Downloads folder and extract the contents
3. Reboot your device in "generic mode" (see "Rebuilding the base image" on [1] for details)
4. Locate the bcmwl folder you extracted to and double-click setup.sh
5. When prompted, choose "Run in terminal"

The rest will be automatic. On reboot, the STA driver should be active.

Prevent the "Unlock your Keychain" prompt from appearing

Some apps, particularly a "signed in" copy of Google Chrome, like to hit the keychain at startup, which can cause the system to prompt for a password to unlock the keychain. To make it stop:

1. Open a terminal (ctrl-alt-t) and type "seahorse", followed by the enter key
2. Right-click on "Passwords:login" and choose "Change Password
3. Enter your old password (defaulr is "password") and leave the "New" and "Confirm" fields blank.
4. Keep clicking "OK" until the boxes close, and you should no longer be prompted for keychain unlocks.

Saving alsamixer settings for quirky audio cards

A few devices have quirky audio cards which require minor changes to the mixer settings to make microphones work properly. On ubermix versions prior to v1.04, these settings reset to defaults on every boot. To make alsamixer settings "stick":

1. Open a terminal (ctrl-alt-t) and type "sudo gedit /etc/pulse/default.pa", followed by the enter key
2. Locate the "load-module module-device-restore" line and change it to "#load-module module-device-restore"
3. Save and close
