我的新 MSI PE60 2QE 笔记本电脑安装了英特尔集成显卡芯片组 5600，连接到三星 156HL01-102 显示器。
当我使用内核命令行中的“nomodeset”参数启动时，显示器工作正常 - 但使用帧缓冲区驱动程序，它不允许使用多个显示器。
启用 KMS 后（通过删除“nomodeset”参数），X 可以使用英特尔驱动程序正确启动，并且我可以使用多台显示器，但笔记本电脑的面板出现不规则闪烁，从偶尔闪烁的水平黑线（这真的很烦人）到持续的闪烁和闪烁，使显示器几乎无法使用。
连接到 DP 端口的外接显示器工作正常。我还没有尝试过 HDMI。
我尝试过的方法（我发现许多其他方法都不相关）：* 创建一个与显示器特性相匹配的新 (1.3) EDID，如https://www.osadl.org/Single-View.111+M5ec938a7b3b.0.html * 使用 xrandr 设置不同的视频模式 * 按照此处的建议使用内核 3.19.0.25 和 i915.enable_IPS=0 进行引导：Ubuntu Gnome 14.04 上的屏幕闪烁 - 4K 分辨率 * 使用 i915.powersave=0 启动 * 使用 acpi_osi=Linux 启动
我怎样才能使英特尔驱动程序正常工作而不出现这种闪烁？

答案1
在 compizconfig 中关闭“取消重定向全屏窗口”或使用终端：
gconftool-2 --set /apps/compizconfig-1/profiles/Default/plugins/composite/screen0/options/unredirect_fullscreen_windows --type bool 0
答案2
我在 Ubuntu 上也遇到过类似的闪烁问题。在我的情况下，在“设置”->“显示”中禁用“未知显示”很有帮助。也许这对你的情况也有效。
答案3
要解决您的问题，请安装最新的稳定版本短期分支 NVIDIA 驱动程序 355。
但首先要撤消所做的所有更改，以将系统恢复为标准配置。
删除所有参数 - 卸载您之前安装的所有 NVIDIA 相关软件。
启动 Ubuntu 系统，当出现登录屏幕时按Ctrl+ Alt+ F1。
输入用户名和密码然后执行：
sudo apt-get purge nvidia*
sudo reboot
笔记：
如果您安装了 bumblebee，也请删除该软件包（它将被 nvidia-prime 取代）。
在这种情况下，命令将是：
sudo apt-get purge nvidia* bumblebee
sudo reboot
现在安装新的驱动程序和 NVIDIA Optimus 支持。
当登录屏幕出现时按Ctrl+ Alt+ F1。
输入用户名和密码然后执行：
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-355 nvidia-prime
sudo reboot
如果你需要在 BIOS 中选择要使用的卡，英伟达或者 可切换图形模式。
打开NVIDIA X 服务器设置->主要简介在英特尔和 NVIDIA GPU 之间切换。
答案4
使用 17.04 alpha
这对我来说停止了闪烁；nano 到 /etc/modprobe.d/i915.conf 并添加以下内容（通常该文件不存在）并重新启动：
*# 由 DW 3.3.2017 添加，尝试停止 i915 闪烁
选项 i915 enable_rc6=7 enable_psr=2 enable_fbc=1 lvds_downclock=1 信号量=1*
