对于驱动程序，我正在运行 NVIDIA 的最新测试版本，如下所示：
*-display

启动后，我会看到 2总是但HDMI-0屏幕不乱动就无法工作。有时只需在“设置-显示”中移动方向即可，有时此命令有效：
sleep 5 && xrandr -d :1 --output HDMI-0 --auto
第三个屏幕始终在 NVIDIA 控制和设置中注册xrandr，但就是不打开（“黑屏”）。查找日志时，我找不到错误（/var/log/syslog），如下所示：
Aug 29 06:48:56 therion /usr/libexec/gdm-x-session[3560]: (II) NVIDIA(0): Setting mode "DP-4: nvidia-auto-select @1080x1920 +0+0 {ViewPortIn=1080x1920, ViewPortOut=1920x1080+0+0, Rotation=90}, DP-0: nvidia-auto-select @1080x1920 +4520+0 {ViewPortIn=1080x1920, ViewPortOut=1920x1080+0+0, Rotation=270}, HDMI-0: nvidia-auto-select @3440x1440 +1080+480 {ViewPortIn=3440x1440, ViewPortOut=3440x1440+0+0}"
最后，dmesg仅解决一些错误，例如：
[48033.822745] [drm:nv_drm_master_set [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to grab modeset ownership
（不过此时，屏幕曾是在职的）
我可以使用哪些日志或流程来诊断为什么一个屏幕偶尔不工作？我注意到进入睡眠状态和解锁有时也能解决我的问题。
