intel dri 3?

xorg 에서 4k 모니터 사용시 화면찢어짐이 발생해서 검색해보는데

dri 3 사용하면 해결된다고 해서 찾아보는 중.

 

검색해보니 리눅스 진영에서 만들은 일종의.. 리눅스용 direct X 같은 가속 구조로 봐야하나?

The Direct Rendering Infrastructure (DRI) is the framework comprising the modern Linux graphics stack which allows unprivileged user-space programs to issue commands to graphics hardware without conflicting with other programs.[6] The main use of DRI is to provide hardware acceleration for the Mesa implementation of OpenGL. DRI has also been adapted to provide OpenGL acceleration on a framebuffer console without a display server running.[7] DRI implementation is scattered through the X Server and its associated client libraries, Mesa 3D and the Direct Rendering Manager kernel subsystem.[6] All of its source code is open-source software.
