In the Steam store, Beyond a Steel Sky supports Linux, but I don't see it in Gog. Can someone clarify the state of this game in Linux?

I emailed the developer who had this response:

" Hi Linux users!
You know how much we've always loved you all. This is why we held back the Linux executable an extra few days to put the finishing touches on it.
GOG will receive a small update to accommodate you all in the next few days! We would never forget about you!


So if you're worried about missing out on the discount, you can absolutely buy the game and it will probably update on Monday.
GOG already received everything they need so it's just a matter of repackaging it, and hosting it. :)"

Apparently they had posted this to Twitter but I don't use that.

Linux version has been added today!

UPDATE: My assumption was correct. Starting pulseaudio daemon and disabling my HDMI audio device gave me sound. I have been playing it a couple of hours with no issues at all.
Running Arch linux with the wayland compositor swaywm.

Yea it was released today.

Tried it and it runs just fine. But i have no sound.

I have a strong suspicion the game picks up the wrong sound device.

Output of `aplay -l` is:

If only there was a way of actually getting some logging out of the game.

I have sound but the game gets stuck at the title screen and the computer locks up totally.

Running it on my Thinkpad t460s, I7-6600u, Intel HD 520, 12 GB ram and Arch Linux.

The game works fine on a lower specs thinkpad t450s, Intel I5-5300u, Intel HD Graphics 5500, 8GB ram and Windows 10.

Just tryed to install the windows version under wine. Insstalled fine and executed it by the binary in $HOME/.wine/drive_c/GOG Games/Beyond a Steel Sky/BASS2/Binaries/Win64/BASS2-Win64-Shipping.exe

Worked without any issues.

If you run the "BASS2.exe" you will be prompted to install Microsft c++ runtime and that will fail. At least on my Arch install. So skip that and use the above .exe instead ;-)

After the latest patch that moved the game to the latest UnrealEngine that uses Vulkan instead of OpenGL made the game work flawless!

If you have had issues with the Gnu/Linux version maybe it will run for you now.

Works great on my T460s with Arch Linux and BSPWM.

I can't start the game

Exiting abnormally (error code: 1)

Seems that minigalaxy installed the game faulty

> Exiting abnormally (error code: 1)

This is stupidly vague Unreal Engine 4 error message, most of the time meaning that the UE4 executable can't find game resources.

It turns out that external installers such as Lutris or minigalaxy (or Bottles?) only extracts the game's mojosetup archive, without running GOG post-install script which actually unpacks the UE4 .pak.splitXX files.

When GOG mojosetup game .sh script is run from terminal or GUI, the GOGPostintall runs automatically as a part of installation process. External installers somehow skip this step. One can run GOGPostinstall manually as well, just go to dir where the game has been installed and run:

./support/postinst.sh

I’m getting Vulcan issues. As I start the game I’m greeted with ‘Cannot find a compatible Vulkan device or driver. Try updating your video card to a more recent version and make sure your video card supports Vulkan.’ error message and the following output on the terminal:

I’m running on Debian with RTX 3090 and have nvidia-vulkan-icd:amd64, nvidia-vulkan-icd:i386 and vulkan-tools packages installed.

Does anyone have any ideas what might be the issue and how to solve it?

I solved this issue with this :
1) apt-get purge nvidia-primus-vk-wrapper:amd64 nvidia-primus-vk-common
2) apt-get install --reinstall libnvidia-gl-550

Of course, the 550 is to be changed depending on your NVIDIA driver version
dpkg -l | grep libnvidia-gl

Technical explaination:
The packet nvidia-primus-vk-common transform the file /usr/share/vulkan/icd.d/nvidia_icd.json to /usr/share/vulkan/icd.d/nvidia_icd.disabled_by_nv_vulkan_wrapper
While the packet libnvidia-gl-XXX brings the file /usr/share/vulkan/icd.d/nvidia_icd.json
