I highly doubt this has anything to do with linux, but NOT everything is accessible playing with a gamepad. I could not find a way to select various things (the queued actions to cancel them, the next pages in the character equipment menu, characters walking the guild hall to talk to them, the next page in the compendium) and every time I feed my yolk, I need to restart the game because the dpad stops working as soon as the food action is greyed out.

Easiest solution was to set right trackpad to mouse so I can click on everything, and queue food after another action instead of clicking it directly.
