Radeon with GLAMOR support

  • only Radeon cards with GLAMOR support are supported at this time >= HD 6000
  • for the HD 6000 series you must enable Option “AccelMethod” “glamor” in your xorg.conf files!
  • don't expect any messages about DRI3 in Xorg.0.log! XServer is mostly silent about it.

nVidia

  • it should just work at this time

How to verify that DRI3 is running?

  • this will work only for Mesa-3D with debug enabled or libgl1-mesa-glx-dbg package on Ubuntu!
  • run glxgears or any simple application with gdb app_name
  • break dri3_swap_buffers will set a breakpoint in dri3_swap_buffers
  • run and it should stop at this function. If it doesn't, you're not using DRI3
