For Intel hardware, you can use: - SNA: xf86-video-intel, which accelerates the 2D api for Intel GPUs - Glamor/modesetting: implements the 2D api in OpenGL Different distributions choose different defaults. A GPU hang caused by Xorg can be caused by SNA or Mesa's implementation of the GL commands sent by Glamor. Some Mesa GPU hangs have been recently fixed by: 180653c357d19ca88f7895f59874a58fac99cc53 Author: Topi Pohjolainen <<a href="mailto:topi.pohjolainen@intel.com">topi.pohjolainen@intel.com</a>> i965/blorp: Make post draw flush more explicit Some SNA GPU hangs have been recently fixed by: 4acd4a7d3d2f41227022fa7581cfb85a0b124eae author Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> sna/gen9: Emit a dummy primitive between VertexElements Make sure you use versions that have those patches.
