HDMI1断开


13

我正在尝试让辅助显示器与笔记本电脑一起使用。我正在运行Ubuntu 16.04 LTS。我在同一台笔记本电脑上安装了Windows 10,并且可以在Windows 10中使用。当前xrandr -q输出:

Screen 0: minimum 8 x 8, current 1600 x 900, maximum 32767 x 32767
eDP1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 382mm x 215mm

   640x480       59.94  
   720x405       60.00  
   640x360       60.00  
HDMI1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

我在dmesg中看不到任何突出的内容,并且在插入HDMI和弦时/var/log/Xorg.0.log没有记录任何内容。

根据lspci -v我对于我的图形卡的描述:

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) (prog-if 00 [VGA controller])
        Subsystem: Toshiba America Info Systems Haswell-ULT Integrated Graphics Controller
        Flags: bus master, fast devsel, latency 0, IRQ 48
        Memory at a0000000 (64-bit, non-prefetchable) [size=4M]
        Memory at 90000000 (64-bit, prefetchable) [size=256M]
        I/O ports at 5000 [size=64]
        Expansion ROM at <unassigned> [disabled]
        Capabilities: <access denied>
        Kernel driver in use: i915
        Kernel modules: i915

我安装了xserver-xorg-video-intel和libdrm-intel1。

我也尝试过

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode HDMI1 1920x1080_60.00
xrandr --output HDMI1 --mode 1920x1080_60.00

然后我得到的最后一条命令xrandr: Configure crtc 1 failed

xrandr --output HDMI1 --auto 什么也没做

任何人推荐什么或尝试什么?当我插入HDMI和弦时,显示器的电源指示灯变为蓝色,然后几秒钟后,它显示“未检测到信号”。因此它至少知道它已插入,但就像笔记本电脑不在那儿听。

解决了,我只需要运行以下命令:

xrandr --output HDMI1 --auto --right-of eDP1

我面临着几乎相同的问题。我建议您在拥有nvidia驱动程序的情况下删除nvidia驱动程序,然后重新安装最新版本,并再次引导,在引导时输入安全密码(在安装新nvidia驱动程序时设置的密码),这可以解决我的问题
