我的系统中的桌面文件包含运行 flatpak steam 的代码：-
/usr/bin/flatpak 运行 --branch=stable --arch=x86_64 --command=/app/bin/steam-wrapper --file-forwarding com.valvesoftware.Steam @@u %U @@
我检查了flatpak 手册上面画着这面旗帜——
--env=VAR=VALUE
在应用程序中设置环境变量。这会更新元数据中的 [环境] 组。这会覆盖应用程序元数据中的上下文部分。此选项可多次使用。
由于 DRI_PRIME=1 可以设置为应用程序的环境变量，以便使用专用 GPU，例如
env DRI_PRIME=1 program_to_run
我修改了我的 steam 桌面文件中的命令如下 -
/usr/bin/flatpak 运行 --branch=stable --arch=x86_64 --env=DRI_PRIME=1--command=/app/bin/steam-wrapper --file-forwarding com.valvesoftware.Steam @@u %U @@
现在，DRI_PRIME=1 已为整个 Steam 启用，在启动时将自动用于游戏。希望这对您有所帮助 :-)
