--------------- ubuntu-touch-meta (1.221vivid46) vivid; urgency=medium * Added aethercast to touch (LP: #1625068) -- Łukasz 'sil2100' Zemczak <[email protected]> Mon, 19 Sep 2016 13:50:42 +0200 ** Changed in: ubuntu-touch-meta (Ubuntu RTM) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-touch-meta in Ubuntu. https://bugs.launchpad.net/bugs/1625068 Title: aethercast binaries disappeared from the system Status in Canonical System Image: New Status in aethercast package in Ubuntu: Confirmed Status in ubuntu-system-settings package in Ubuntu: Confirmed Status in ubuntu-touch-meta package in Ubuntu: Fix Committed Status in ubuntu-touch-meta package in Ubuntu RTM: Fix Released Bug description: After update to 182, the aethercast binaries disappeared from the system, leaving the external display page in system-settings broken. phablet@ubuntu-phablet:~$ system-image-cli -i current build number: 182 device name: turbo channel: ubuntu-touch/rc-proposed/meizu-pd.en last update: 2016-09-18 20:11:35 version version: 182 version ubuntu: 20160917 version device: 20160824-d33b825 version custom: 20160831-992-8-12 UPDATE: I've been told the change to make aethercast an option suggestion in system-settings caused to not have aethercast pulled in in the image builds. It seems like there are 2 fixes needed: a) Seed aethercast in relevant phone images b) fix system-settings to hide the external display section when aethercast is not around. Currently the button is there but just does nothing.
