Notes related to gayming

A lot of older files that I haven’t touched recently were moved to this directory. I don’t think anyone was using them, so I am not afraid of breaking links.

Wayland / Sway

Issues and solutions

sudo flatpak override --env=SteamDeck=1 --env=MANGOHUD=1

Constant camera rotation

Reload Sway in-game, $Mod+Shift+C and it should stop.

Cursor doesn’t stick to game window

Run the game with gamescope if it’s a problem. Or you could somehow bypass the launcher or remember options if controller is used.

Steam? Edit launch options for the game (second click, properties, general, launch options):

SteamDeck=1 MANGOHUD=0 gamescope --steam --borderless --mangoapp -- %command%

See also gamescope --help

• SteamDeck=1 sends same variable as Steam Deck and magically fixes some games. E.g. Kingdom Hearts: Birth by Sleep (part of KH 1.5 + 2.5 HD), except that it has screen tearing which gamescope fixes.
• MANGOHUD=0 disables mangohud so there won’t be two of them (sudo flatpak override --env=MANGOHUD=1)
• --steam - enables Steam integration, whatever that is
• --borderless borderless full-screen mode (that Sway may be making windowed though)
• --mangoapp enables mangohud (and without the previous disabling there are two overlapping ones)

It might be the best to run Steam with gamemoderun and have SteamDeck=1 be part of the environment otherwise alongside MANGOHUD=1 so only gamescope and Proton version would require game specific configuration.

Graphics corruption such as display full of black dots

When the previous launch options cause this,

INTEL_DEBUG=norbc SteamDeck=1 MANGOHUD=0 gamemoderun gamescope --steam --borderless --mangoapp -- %command%

I saw this advice at gamescope#356 which says it’s tracked at freedesktop.org/mesa/mesa#6029.

Steam client itself is laggy

Close/logoff friends window/network or disable its animations.

Fedora Atomic

Means Fedora Kinoite unless otherwise specified. Read also aminda.eu/n/essentialsoftware which may cross-reference here.

Heroic Games flatpak

• When asked for Steam flatpak location, it’s ~/.var/app/com.valvesoftware.Steam/data/Steam. The data/Steam confuses me too.
• No input in Skyrim Special Edition GOG? Try quitting Steam. That may also affect other games.
• Don’t enable mangohud within Heroic. It should enable itself through MANGOHUD=1 (sudo flatpak override --env=MANGOHUD=1)
• Gamescope and Mangohud installed, but not found? Pay attention to their branch, at the time of writing they want branch 24.08.
  • Remember the dualslash shortpaw! sudo flatpak install flathub org.freedesktop.Platform.VulkanLayer.MangoHud//24.08 org.freedesktop.Platform.VulkanLayer.gamescope//24.08

Actually using gamescope

Hooking error that you can ignore and proceed by pressing OK? Disable gamescope. And mangohud, see above.

Having gamescope and mangohud installed and found? That is not enough to use it.

It’s weird. You have to check the “enable upscaling” box, then set “Game Width” and “Game Height”, but leave “Upscale {Width,Height}” empty.

• @rtxn@lemmy.world on How the heck do I get gamescope working with Heroic Games Launcher?

Same page may have hinted me on the branch version numbers, but I lost the source for that. And then they updated them anyway and I had to figure out by myself that I had to install the newer branch.

Steam flatpak

See also above and below. Remember to sudo flatpak install flathub com.valvesoftware.Steam.CompatibilityTool.Proton-GE and in Steam settings find the checkbox to make everything run with compatibility tool Proton GE (flatpak). That however doesn’t apply to Steam Deck/Play compatible games so you will have to edit the compatibility settings for them and force Proton GE (flatpak) (and the launch options) for everything by yourself.

If you neglect changing the proton version, everything might just work, or you will get a hooking failure warning that lets you press ok to proceed anyway and everything might still be working, or you may have screen tearing and require gamescope far above in this document to fix it.

Steam Deck

If using Fedora Kinoite, life may be easier by making symlinks to autostart the gayming apps on login

mkdir -p ~/.config/autostart/
ln -nsfv /var/lib/flatpak/exports/bin/com.valvesoftware.Steam ~/.config/autostart/
ln -nsfv /var/lib/flatpak/exports/bin/com.heroicgameslauncher.hgl ~/.config/autostart/

Visit Steam settings to enable launching in big picture mode and Heroic Games Launcher settings to start minimized.
