So I've experienced the same issue you have with MC theater view. The issue is that sometimes the MC theater view window isn't "in focus" even though it occupies the whole screen. That's why it works normally once you've clicked the mouse on it once, the window is then focused and MC can receive the remote keypresses. In my case, the issue only seems to happen when I configure MC to start up in theater view; if I start up in standard view and then switch to theater view I don't see the issue. Can you give steps to reproduce it for you? That might help bob identify the problem.
For uninstalling, how did you install MC28 to begin with? The answer will be different depending on how you installed it. Have you tried just using something like "apt-get remove mediacenter28"?
Hi,
Funny enough I was thinking exactly about the MC not being in focus even as it appears in Theater view in all its splendor.
But the problem gets worse though as sometimes (many times actually) the screen becomes completely blank after the two Theater View buttons briefly appear for a few seconds and some text saying "press left, right, up, down to navigate, and OK to accept. Press green button to return home.". Then the infamous blank screen.
When this happens I have to connect a keyboard to my HTPC and try to access the Ubuntu desktop and then eventually kill the MC29 or alternatively go back to Standard View, as opposed to Theater View because at least I'm able with my remote to switch view modes, even when the screen is blank.
Other times, it is like you wrote. No blank screen but the app is not on focus. I've just experienced both these situations right now. When I don't get the blank screen, if I click anywhere then my remote OK works!
I have MC configured to always start in Theater View whenever I switch on my HTPC.
What else can I do to help troubleshoot this?
EDIT: I forgot to mention that I've googled and ended up removing MC with that command you wrote: 'apt-get remove mediacenter28'. I don't remember how I've installed it at the time. I followed some instructions on a thread over here.
There is one other thing I've reported a while ago
here and read that it was corrected but I regret to inform that it is not, at least on MC29. I'm talking about the cursor arrow that is still visible in Theater View which should not happen.
