I’m running into this issue with dungeon crawl stone soup. Definitely for the tiles version, and I think also for the console version (but it won’t launch, claiming the terminal dimensions are wrong… probably too narrow?)
I had to build it from source to run on arm, following debian instructions in INSTALL.md
I noticed the same thing with both Steam Link and Moonlight client.
I don’t think it’s X related, since I have to launch them from a console tty for them to run (beside the current X wm), and running the xrandr rotate command from another tty does nothing.
Maybe the defaut orientation is hardcode in these programs… Maybe some kind of wrapper can do something ?
I only managed to have moonlight-qt running (with wrong orientation), I will try to make moonlight-embedded run since it seems to support a "rotate"option. Wish me luck :-p
I recently received my uconsole and was trying out Kodi and saw this problem where it displays rotated 90 degrees to the left. I noticed that going full-screen on VLC videos also causes this. Would love to know if anyone has been able to get Kodi to run in the normal screen orientation.
