올바른 디스플레이 해상도를 설정할 수 없습니다

현재 Debian 테스트가 있는데 Dell U2718Q를 표시하도록 해상도를 설정할 수 없습니다.

# inxi -Gxx

           version: 3.3 Mesa 17.2.5 (compat-v: 3.0) Direct Render: yes

/etc/X11/xorg.conf:

Section "Device"
    Indentifier  "Intel Graphics"
    Driver       "intel"
    Option       "AccelMethod" "sna"
    Option       "TearFree" "true"
EndSection

하지만 이는 문제 해결에 도움이 되지 않습니다.

나는 다음을 설정하려고 한다:

# xrandr --output HDMI-1 --mode 3840x2160_60.00
xrandr: Configure crtc 0 failed

또한 --crtc 옵션을 사용해 보았지만 결과가 없습니다.

xrandr 출력:

xserver-xorg-video-intel, xserver-xorg-video-all, xserver-xorg-core 패키지를 설치했습니다.

어떤 도움이라도 부탁드립니다.

고쳐 쓰다:
