Troubleshooting

Steam web pages still do not load

Check the proxy file Deckless is reading:

DECKLESS_PROXY_ENV
~/.config/deckless/proxy-env.sh
~/.config/network/proxy-env.sh
inherited shell proxy variables

Things to verify:

the proxy URL includes a scheme such as http:// or socks5h://
local addresses are included in no_proxy
the proxy itself is reachable outside Steam

Games are using the proxy when they should be direct

Deckless clears standard proxy environment variables before starting Steam. If a game still uses a proxy, the most likely causes are:

the game has its own proxy setting
a system-wide transparent proxy is in place
another launcher is injecting environment variables after Deckless starts Steam

Big Picture still falls back to software rendering

Confirm that your system has working graphics userspace outside Steam first. Deckless only removes some Steam-side blockers; it cannot fix a broken driver stack.

Useful checks:

command -v gamescope
glxinfo -B
vulkaninfo --summary

Also check whether your system exposes one of these paths:

/run/host/usr/lib/gbm
/usr/lib/gbm
/run/host/usr/share/glvnd/egl_vendor.d
/usr/share/glvnd/egl_vendor.d

Big Picture launches but the game does not take fullscreen on i3

The i3 bridge depends on:

i3-msg
jq
an i3 session that processes XDG autostart entries, or a manual bridge start

You can start it manually with:

/usr/bin/bash ~/.local/share/deckless/bin/deckless-i3-bigpicture-bridge

If the game first opens a launcher window, that launcher may briefly take the fullscreen seat before the actual game window appears.

I want to go back to plain Steam

Run:

./uninstall.sh

Deckless restores previously backed up local launchers and desktop entries when they existed at first install.
