Vulkan on X2Go

[feheim]

Currently we can run Unigine (Editor and Applications) on Linux remotely in X2Go with OpenGl und VirtualGL (vglrun).

2.17 introduced Vulkan Support, however I did not manage to open the Editor with Vulkan and X2Go. It crashes with sigsegv and no further information.

As OpenGL is about to be removed with 2.18, we need another possibility to run Unigine on X2Go.

Did anyone manage to run Unigine with Vulkan in X2Go ?

Have you tried to use xrdp with glamour for that task? At least some say that even Vulkan apps are working fine (not tested personally).

Some issues are still not fixed, such as nvidia drivers not allowing to change screen resolution in headless mode (need to insert dummy HDMI / DP adapter to GPU to emulate monitor connection.

Thanks!

Unfortunately, for the time being, I'm stuck to the current setup. This means, I cannot try xrdp.

Can you run any other Vulkan app with X2Go? If that's a software limitation, I'm afraid we can't do anything here until it will have proper Vulkan support.

No, unfortunately vkcube, a simple Vulkan Cube Application, also does not work. The assertion for errors in demo_init_vk_swapchain does throw.

If you have an idea what is missing in our general setup, help would be much appreciated.

After conducting tests with X2Go we discovered that hardware acceleration with Vulkan is only supported for Linux-Linux RDP (and only if you are using the Gnome DE on both the host and client). It seems that Linux-Windows RDP is currently not possible to achieve with Vulkan.

As an alternative option, you can try setting up XRDP to see if it works as expected.
