[Linux] Shadwen does not run (segfault)

[daxel3]

I'm running Ubuntu 16.04 64bit with nvidia drivers (340.96).

When I run the Steam-Version I get to the launcher. Clicking "Start Shadwen" does not launch the game. In the DRM-free version from Humble Bundle I get

Code: Select all

nohup: redirecting stderr to stdout

When I manually set the LD_LIBRARY_PATH and run the game binary directly, I get

Code: Select all

[1]    4991 segmentation fault  ./bin/shadwen_linux_64bit

ldd outputs these libraries:

I also ran strace on the binary. The result is here:

I hope this helps in finding the problem.

What GPU do you have, and did you test it with the latest Nvidia driver? Yours looks outdated.

[daxel3]

I've got an Nvidia 9500GT that comes with the MacPro. That limits me the the 340 series of drivers. That card is a bit dated but should be enough to run Shadwen.

I see. Then better wait for developers' input.

Sorry for the delay!

Unfortunately it seems like your graphics card might not support OpenGL 4.1 which the game would need. To confirm this you can check your system's supported OpenGL version by running the following commands:

Code: Select all

sudo apt-get install mesa-utils

and then

Code: Select all

glxinfo | grep "version"

You can also just in case add the longer version which you can get by running:

Code: Select all

glxinfo

Let me know if you have any questions. Cheers!

OpenGL version string: 3.3.0 NVIDIA 340.96

Yep, looks like it's too old. I guess I'll finally have to figure our how to upgrade the graphics card in this MacPro. If it doesn't work in Linux it won't work in Windows, either, right?

Unfortunately yes, your graphics card most likely won't run Shadwen. 9500 GT is quite much below our minimum requirements even for Windows. You can try it if your other specs are fine, but sadly I can't promise any good results even on the lowest settings.

Let me know if you have any other questions. Cheers!

The problem is not only that the card is too "old" or to "slow". The game needs a higher OpenGLversion. I can not understand why the coders do that. Many people can not play the game, because the free open source drivers have only OpenGL 3.3.
All people who use Ubuntu 16.04 or Debian testing or a newer distro can not even play the game with a R9280X or R390 for example, because amd build no fglrx driver for the new xorg 1.18 any more. So you see, the cards are not always to "old" or to "weak".

[shmerl]

Requiring high OpenGL version is OK. If you use open drivers, stick to recent AMD (Polaris cards like RX 480). amdgpu + radeonsi are progressing nicely.

That's right. But I do not buy a new graphic card because of amdgpu driver. For me the R9280X and R9390 have enough power. The R9280X have only GCN1.0 and I do not doubt that amd buil the amdgpu driver or this card. GCN1.1 has experimental support....
