我有 nvidia gtx 980（驱动程序 v. 364.19）、MSI X99S MB、i7-5820k 32GB DDR4 内存。
我的设置是 3 个 4k 显示器（在 DP-0、DP-2 和 DP-4 上）
在我的显示器进入睡眠状态后（计算机没有进入睡眠状态），当我尝试唤醒显示器时，系统负载逐渐上升，并且持续上升。CPU 没有增加（偶尔 xorg CPU 会跳到 100%）。我无法远程登录。我必须使用电源按钮强制关机并重新启动计算机。我在 15.10 中没有遇到这个问题。
我找不到任何有意义的错误。我尝试了网上建议的许多方法。
我将 nvidia 模式设置设为 0。我认为内核会忽略这一点。
Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.4.0-23-generic.efi.signed root=UUID=34f125fb-0746-481f-94de-974b47825aab ro nouveau.modeset=0 nvidia.modeset=0 nvidia-drm.modeset=0 nomodeset
但随后我收到以下启动消息：
nvidia-modeset: Loading NVIDIA Kernel Mode Setting Driver for UNIX platforms 364.19 Tue Apr 19 14:15:03 PDT 2016
我正在寻找解决方法。我认为这是内核/nvidia 驱动程序错误，可能与模式设置有关。驱动程序 355.11（模式设置之前）没有出现此问题
我想补充一点，崩溃时我在系统日志文件中发现了以下内容。如果我理解正确的话，这表明 nvidia_modese 存在问题
