Dota 2 won't launch with -vulkan on a linux laptop

Your system information

• System information from steam (Steam -> Help -> System Information) in a gist:
• Have you checked for system updates?: [Yes]
• Are you using the latest stable video driver available for your system? [Yes]
• Have you verified the game files?: [Yes]

Please describe your issue in as much detail as possible:

Dota 2 when running with -vulkan only the cursor that changes but the game won't launch. -gl works, but -gl is not an option as it decreases fps, i gain a much more stable gameplay with vulkan. Already tried with Steam runtime container with no luck, cleaning the shader cache, disabling and enabling it still nothing. participating in the beta and upgrading my video driver also didn't help at all.

other side notes : csgo, left 4 dead works, only happens to Dota. `` here's a log when i run dota.sh through terminal :

Steps for reproducing this issue:

1. Launch Steam, Steam.sh or anything
2. Launch Dota 2 with -vulkan, also with Nvidia driver
3. Game won't launch, only showing cursor

Hello @Mameng57, Dota 2 is intended to be run in the scout-on-soldier container environment, and running dota.sh directly has given you a false lead. If you completely close Steam, then run steam from a terminal, is there a better hint in the terminal spew? It looks like you're using a distro-modified Steam package, and some of that terminal spew might get redirected to ~/.steam/error.log.

Looking at your system information, it looks like your NVIDIA driver install is incomplete, missing the driver's 32 userspace libraries. This shouldn't directly affect Dota 2 since the game is 64 bit.

hey, thanks for the heads up. about the nvidia driver you're right, reinstalled it and is now properly detected by steam. also i forgot to mention that my steam library are stored on an NTFS drive, so there was also an issue with that as well, but i got it fixed by following this instruction Linux games on NTFS .

So after the video card update, shader cache were redownloaded and somehow it's working now
