- Fixed start.sh environment variable loading from systemctl
- Use here-document (<<<) instead of pipe for subshell to preserve exports
- Added better error handling for evdev device enumeration
- Added exception handling in intro video playback with detailed logging
- App now properly initializes with DISPLAY=:0 and WAYLAND_DISPLAY=wayland-0
Critical fixes for image editing workflow:
1. Keep local edited files as backup (don't delete after server upload)
- Server may not process upload immediately
- Keeps edits safe locally in case server fails
- Prevents loss of edited images
2. Include original filename in metadata sent to server
- Server needs to know which file was edited
- Allows proper tracking and versioning
3. Improved error logging for server upload
- Now logs detailed errors (404, 401, timeout, connection)
- Shows clear messages when server doesn't support endpoint
- Helps diagnose why edits aren't syncing to server
4. Better user feedback during save
- Shows 'Saved to device' status first
- Then 'Upload in progress' to show server sync happening
- Clarifies local vs server save status
Bug symptoms fixed:
- Edited images now persist locally after restart
- Server upload now sends correct file information
- Clear error messages if server upload fails
- User understands 'local save' vs 'server sync' steps
- Commented out forced pygame backend (causes issues with display initialization)
- Added SDL_VIDEODRIVER and SDL_AUDIODRIVER fallback chains (wayland,x11,dummy)
- Limited KIVY_INPUTPROVIDERS to wayland,x11 (avoids problematic input providers)
- Reduced FFMPEG_THREADS from 4 to 2 (conserves Raspberry Pi resources)
- Reduced LIBPLAYER_BUFFER from 2MB to 1MB (saves memory)
- Fixed asyncio event loop deprecation warning (use try/except for get_running_loop)
- Better exception handling for cursor hiding
These changes fix the app crashing after 30 seconds due to graphics provider issues.
