저는 HDMI 출력을 화면에 표시하기 전에 직접 조작하는 일부 특수 하드웨어에서 Ubuntu 14.04.1을 실행하고 있습니다. 나는 Xrandr이 계속해서 호출되고 기록되는 것처럼 Xorg 로그가 때때로 지속적인 출력으로 미쳐가는 것을 발견했습니다.
Xorg 로그에 며칠이 지나면 이 줄은 500밀리초마다 반복됩니다.

하드웨어는 AMD 라데온 HD 8210 그래픽 칩을 사용하는데, 여기에 연결된 디스플레이 장치가 이상하다. 4K 화면으로 렌더링되지만 높이가 절반이므로 1920x540에서 실행해야 합니다.
X는 그 직후 사망한 것으로 알려졌다. 무슨 일이 일어날 수 있나요?
