UPDATE: thanks to a comment, you can get Ubisoft Connect to auto-launch a specific game by adding uplay://launch/*gameID*/0 to the end of your Steam launch options for the app (ID list here) which gets around the flashing issue but only works for a specific game at a time. A problem shared by many launchers right now.

In Gaming Mode on the Steam Deck, you need to quickly close Ubisoft Connect once you hit Play on a game, otherwise Gamescope (the SteamOS compositor) gets confused on what to display and madly flashes between the launcher and the game. Ensure the path is the same as your SD Card, you can find it listed as 'Primary' in the Dolphin file manager at the bottom of the left panel.Ī special important note: ensure you've set Ubisoft Connect to minimize when closed in the settings. This tells Proton it can use the SD Card and where it is. In the same Properties menu, there's a Launch Options box, you need to add this into the text area: STEAM_COMPAT_MOUNTS=/run/media/mmcblk0p1/ %command%

Then go into these folders to select the right exe file '/pfx/drive_c/Program Files (x86)/Ubisoft/Ubisoft Game Launcher/UbisoftConnect.exe'.įor SD Card access, you also need one minor adjustment. You can also find the right one by expanding the box to see what folder was modified today. Do this by hitting Browse and go to '/home/deck/.steam/root/steamapps/compatdata/' and find the folder with a longer number than usual. Right click on it in your Steam Library again and go -> Properties -> change the Target to the newly installed file.

Then run it as normal and let it install.

Right click it in your Steam Library and go to Properties -> Compatibility, tick the Force box and select Proton 7 or Proton Experimental.

In your Steam Library, add a Non-Steam game and select the downloaded exe file from the Downloads folder.

Head to Ubisoft Connect and hit the big blue download button.
