[L4D2] Game enters non-standard loading screen after launch and never finishes

[drakon64]

When trying to launch the game, the intro movies play as normal but the main menu will never load. Initially the Dead Center loading screen will appear but will then be replaced with the following:

The progress bar will never progress.

This error is almost completely reproducible via Proton except for the fact that the progress bar moves.

No Workshop mods are installed (the game also never reaches the point of downloading Workshop mods).

Launching the game with +map c1m2_streets will successfully start the second level of Dead Center with the following caveats:

• No audio
• Item glows are broken
• Changing audio settings causes the pause menu to become invisible

Validating game files does not detect these files as missing. I can confirm that the files are present on the system.

Returning to the main menu works except for a missing string:

Trying to open Audio settings returns us to this screen:

The infinite loading bug also affects Counter-Stike: Source

[drakon64]

Team Fortress 2 is not affected

[drakon64]

This appears to be an issue with bcachefs https://github.com/koverstreet/bcachefs/issues/175 https://github.com/koverstreet/bcachefs/issues/650

[drakon64]

I'll do a write-up in the morning as to how to workaround this without having to reformat your entire filesystem. There's still bugs, but now it's "some strings don't load" rather than "literally unplayable"

[ethanholt1]

FWiW, that loading screen happens when you connect to a server through the console and the game has not yet determined what map it uses. Can you show us your L4D2 launch options? Maybe something in there is causing this.

[drakon64]

I'm pretty sure this is a bcachefs issue (as do the bcachefs developers, see https://github.com/koverstreet/bcachefs/issues/175 and https://github.com/koverstreet/bcachefs/issues/650), but regardless here are my startup flags:

SDL_VIDEODRIVER="x11" %command% -novid

[drakon64]

As a workaround to 'force' the game to run from an ext4 filesystem, you can do the following:

fallocate -l 30G l4d2.img
sudo losetup -f l4d2.img
sudo mkfs.ext4 /dev/loop0
sudo mount /dev/loop0 "/home/adamc/Left 4 Dead 2"

You can then add the new mount point as a Steam volume and install the game there.
