Can someone tell me if there is a known problem related to Linux and
multisampling? With SDL 2.0 I can create a window and render OpenGL content
fine, but when I add multisampling:
SDL_GL_SetAttribute(SDL_GL_MULTISAMPLEBUFFERS, 1); // if these two lines
are here
SDL_GL_SetAttribute(SDL_GL_MULTISAMPLESAMPLES, 2); // then SDL_CreateWindow
returns nil
SDL_GL_SetAttribute(SDL_GL_ACCELERATED_VISUAL, 1);
W := SDL_CreateWindow(‘Hello’, 0, 0, 200, 200, SDL_WINDOW_OPENGL or
SDL_WINDOW_SHOWN);
SDL_CreateWindow returns nil and SDL_GetError returns “couldn’t find
matching glx visual”
I’ve tested on my code on Windows and it doesn’t have a problem
multisampling.
I know my hardware can handle multisampling. I have steam installed on this
Linux machine as well as the latest proprietary drivers.
