Got some strange behaviour with PlexHT. I'm running on Ubuntu 14.04 LTS (Upgraded from 12.04 LTS).
When I logon as my normal user PlexHT works fine without any issues (I'm liking the updated UI).
However, if I reboot and let my automatic logon as PlexHomeTheatre run, I get all sorts of weird behaviour:
Graphical flashing, especially when using menus
Juddery menus when moving
Strange menu repeats - 10 'Search' items and nothing else
No audio
An initial Pulse CEC driver error
Shutting down PlexHT and restarting only helps with the 'Search' menu... so I guess it's not a start up issue.
In the absence of any other option I'm wondering if there's a way to flush/reset any PlexHT configuration that could be hanging around on my PlexHomeTheatre user?
What user name is the 'default' user and is it a member of the 'dialout' group (or whatever new group name is used now) as indicated in the discussion?
I think the CEC issue is actually a red herring and due to how quickly PlexHT runs up on startup. It also appears that the audio issue was due to the 14.04 upgrade having altered the audio settings - I believe I've fixed that now.
So, basically, the thing that I'm still struggling with is the flashing/stuttering menu redraws.
To reiterate - I can watch a 1080p movie with out problem, but using the PlexHT menus is flickering. I've also discovered that if I turn on display dirty regions the flickering stops - I just get the expected green flashes indicating the dirty regions.
... it appears I *might* have solved it. I should have mentioned, I upgraded from 14.04 to 14.10, but actually the troubles started back on 14.04 after some PHT update (can't remember which!). What appears to have helped is removing libcec & libcec2, telling apt to clean & update, then installing libcec2 again. This gets the 14.10 (unicorn) build of libcec2 instead of the 14.04 (tahr) version. Maybe that's what fixed it. I also installed all the deps for building PHT since that was my next step, that might have also helped.. details in this thread.
