[Douglas Mackay <launchpad@xxxxxxxxxxxxx>]

I've done some further testing and this issue only occurs when using the
mythbuntu desktop (xfce). If you use ubuntu desktop (gnome) it works
fine.

The WOL command is sent in libs/mythdbcon - OpenDatabase (if frontend
'Ping test server?' is disabled) or in libs/mythcontext -
TestDBconnection (if frontend 'Ping test server?' is enabled.

Commenting out the line that sends the WOL Command and then manually
starting the backend still shows the same issue.

Steps to reproduce :-
On a remote frontend using the mythbuntu desktop (xfce)

1. Install wakeonlan - sudo apt-get install wakeonlan
2. In the frontend -> setup -> general -> Database Configuration 2/2 . Enable Database Server Wakeup, set reconnect time (e.g. 60), retry attempts (e.g. 5) and set wake command to /usr/bin/wakeonlan <Backend MAC ADDRESS>
3. Make sure backend network card is set-up for WOL - although for testing you can manually start it up when required
4. Shutdown backend.
5. Start frontend. When frontend detects that the backend is available it will start to load the theme but then quits back to desktop

ICEauthority issues after remote frontend wakes up database server

Status in Mythbuntu, Ubuntu derivative focused upon MythTV: Confirmed
Status in “mythtv” package in Ubuntu: New

Bug description:
Binary package hint: mythtv

When a remote frontend wakes the database server using the settings in 'Utilities / Setup -> Setup -> General -> Database Configuration 2/2 - Enable Database Server Wakeup' mythtvfrontend will start then immediately exit. Starting mythfrontend when the backend is online works as expected.

When mythtvfrontend fails to start 'ICE default IO error handler doing an exit(), pid = 1561, errno = 32' is logged in mythfrontend.log. Removing ~/.ICEauthority then starting mythtvfrontend (with the backend offline) works as expected however .ICEauthority get recreated when the frontend restarts.
