Some tinkering is needed to fix the black screen issue on startup. See https://github.com/ValveSoftware/Proton/issues/3694#issuecomment-1067313588
Basically create a dxvk.conf in
/home/deck/.local/share/Steam/steamapps/common/Geometry May. I swear it's a nice free game/
and add the following lines and save:
dxgi.deferSurfaceCreation = True
d3d9.deferSurfaceCreation = True
d3d11.maxFeatureLevel = 9_3
Start the game and it should display properly now.
black screen with sound both in game and desktop mode
after run , black sreen on steam deck
ddr=gdi and enabling DirectD3D is required to make the game display properly.
There are slowdowns, but not bad enough to make the game unbearable.
It does have the same slowdown problem as Teleportals and Maytroid, but it doesn't hinder the experience as much as in those two. Maybe it's because of the type of the game, but I don't have the means to "scientifically" measure the difference, so I'm just going with my subjective feeling.
Window came up with sound, but no image (fully black). Input appeared to work. Pressing the enter key caused a menu selection sound to play.
There is working sound and the game appears to receive input correctly, but shows only a black screen.
There is a black screen when the game is launched.
