Real drm KMS users don't need to do this, X should just do a normal ioctl on the device and cause it to happen, echoing detect is only a backdoor for external non-KMS fd opening users, Just clarifying, clearly there is a bug here with the unknowns getting stuck on, hopefully someone can reproduce it and fix it Dave. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
