Small Fullscreen on Linux

[proteo23]

Hi there,

I am trying to run Dolphin fullscreen on my NUC running a fully up-to-date version of Arch Linux. In the past I was able to get fullscreen on the machine, but it has been about a year since I last used Dolphin. I installed the latest Git version of Dolphin and no matter the setting the emulation occurs in a small box (native resolution size?) on the top left of my 1080p screen.

I have tried a mix of ticking the "Fullscreen" option, setting "Auto", "Fixed 4:3", "Fixed 16:9", "Stretch to window" and the emulation never stretches to fullscreen. I do not use a window manager or desktop environment but normally launch from an emulator manager. Launching dolphin-emu directly as part of my xinitrc has no effect. I have also tried to launch the dolphin-emu-cli to directly load an ISO, but the result is also the same. My various other emulators all load straight to fullscreen so it does not seem to be an X session issue.

A few config file snippets-

Dolphin INI:

Code:

[Display]
Fullscreen = True  

GFX INI:

Code:

[Settings]
InternalResolution = 1
AspectRatio = 2

Is there a hidden way to force stretching the size of the emulation box? Any ideas on something I may be missing?

I tried loading Dolphin from a twm instance to test if there were some obscure issues with using the full screen space, but no problems there. Same issue with the settings to use fullscreen, but only a small emulation window starts in the top left corner. Attaching a screenshot of what this looks like for me.

I am beginning to think there may be some sort of bug with how the geometry of the emulation window is being set that is impacting me.

I found an old thread where someone was trying to configure the render window size which gave me an idea.

I patched the default render window sizing in MainSettings.cpp:

Code:

-const ConfigInfo<int> MAIN_RENDER_WINDOW_WIDTH{{System::Main, "Display", "RenderWindowWidth"}, 640};
+const ConfigInfo<int> MAIN_RENDER_WINDOW_WIDTH{{System::Main, "Display", "RenderWindowWidth"}, 1920};
const ConfigInfo<int> MAIN_RENDER_WINDOW_HEIGHT{{System::Main, "Display", "RenderWindowHeight"},
-                                                480};
+                                                1080};

Now I can launch dolphin-emu-cli and automatically have it create a render window that takes up my entire screen. I think technically it is not fullscreen, but since I do not use a window manager I do not see any window borders and it uses the entire screen space. A horrible hack but it works for me for now.

There is definitely a bug that I should file since the expected behavior would be that fullscreen just works. Unclear if the issue is with the screen size detection, configuration options, X window geometry settings, or something else entirely.
