mopidy looks pretty cool. i have used MPD quite a bit and now im trying to get my new raspberry pi 3 with adafruit 2.8" capacitive touch screen working. it has taken me a few days to get things figured out, to get mopidy running and grabbing my local tracks, to get the spotify extension working. i used adafruits easy install image so the touchscreen works and not only do i see console output but the touchscreen test program shows touch inputs working. Mopidy-Touchscreen installed fine and it says its running when i run mopidy (sudo mopidy). i have added root to the audio group and spotify and my local files play fine. unfortunately i dont quite understand how and where i can access the actual touchscreen interface. my pi just shows the INFO lines from mopidy that its running and the extensions are loaded. am i missing something?

ok. i figured it out. i didnt have the lines needed in the mopidy.conf file:

```
sdl_fbdev = /dev/fb1
sdl_mousdrv = TSLIB
sdl_mousedev = /dev/input/touchscreen

```

once i did that, presto change-o… it worked! i was having problems with the mouse pointer being stuck in the upper left corner. the touchscreen would work, it only registered a click in the upper left corner though. so i followed thse instructions to use the old SDL library [https://learn.adafruit.com/adafruit-2-8-pitft-capacitive-touch/pitft-pygame-tips](https://learn.adafruit.com/adafruit-2-8-pitft-capacitive-touch/pitft-pygame-tips) and that fixed the remaining problems. the only issue i still have is no album art for my local files although it is pulling art for the spotify songs. any ideas? anyone?

That screen should show some controls on the top (Volume, pause…). Probably an error happened and because of that nothing is being shown on that screen. I only use Spotify and I made and tested the code to work with it, so probably some adjustments will need to be made to work with Mopidy-Local-Images.

You can run mopidy using the next commad:  
`sudo mopidy > log.txt 2>&1`  
This will save the output to log.txt. Check for errors on the file or post it here so I can check what is going wrong.

@9and3r thanks for taking a look and thanks for writing that cool touchscreen plugin. heres the log. i started mopidy, selected local files, selected a file and then pressed the NowPlaying tab and it was red with no title.

The problem is that the song has no defined duration and because of that mopidy-touchscreen crashes as it expects to get the duration. This error should be already fixed on the development version.  
Install mopidy-touchscreen from [github](https://github.com/9and3r/mopidy-touchscreen) (develop branch) and it should work.

EDIT: sorry. i made a mistake and it was the old version i was installing. once i figured out to download the DEVELOP zip and install that one, the error went away. i am still working on getting local images to work from my MP3 files, does your module require the Mopidy-Local-Images to pull images? where does it get the artwork?

@9and3r hey i have figured something out. if i play local media through a playlist that i created with mpd/mpc:

mpc clear  
mpc -w update  
mpc listall | mpc add  
mpc save allmusic

and then through mopidy i select the playlsit, Mopidy-Touchscreen has the title of the song but says Unknown Artist and Unknown Title and has no playing time. if i play the SAME song through the local media tab, it has playing time and artist and album. i am still NOT seeing album art from local files so my question above is still relevant.

as far as i can tell, the playlist is the only way to play ALL my local music on random. so this is what is holding me back from actually using Mopidy and Mopidy-Spotify and Mopidy-Touchscreen as my main system. any ideas?
