feheim Posted July 24, 2023 Posted July 24, 2023 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 ?
silent Posted July 25, 2023 Posted July 25, 2023 feheim 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).

feheim Posted July 25, 2023 Author Posted July 25, 2023 Unfortunately, for the time being, I'm stuck to the current setup. This means, I cannot try xrdp.
silent Posted July 26, 2023 Posted July 26, 2023 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.

feheim Posted July 26, 2023 Author Posted July 26, 2023 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.
silent Posted July 28, 2023 Posted July 28, 2023 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.
