几个月以来,我在 Ubuntu 20.04 的笔记本电脑显示屏上出现了这些水平线。
我的笔记本电脑是华硕 GL-502vm,配备 6GB GTX1060
此问题不会发生在 Windows 10 上(我使用的是双启动)。此外,当我切换到 nouveau 驱动程序时,一切也都运行正常。(我想我需要用于 Cuda 的 Nvidia 驱动程序)。我也尝试了所有可用的 Nvidia 驱动程序,但所有驱动程序都出现了这种情况。
有时我登录时屏幕会变黑,我必须按住电源按钮才能关闭笔记本电脑。这种情况可能会连续发生多次。
当我可以登录并在显示设置中更改某些内容时,例如缩放(首先到 125% 它停止,然后到 150% 它再次开始回到 100% 然后再次停止),或者在 nvidia x 服务器设置中设置欠扫描有点并单击应用它也会停止。
当我通过 hdmi 或 displayport 连接外接显示器时,外接显示器工作正常,但我的内置显示器有时工作有时不工作。
我打电话给华硕服务台,他们告诉我显示器电缆坏了,所以我更换了它。但这没有效果。
我也尝试过Force Composition Pipeline
Nvidia Force Full Composition Pipeline
x 服务器设置。但是没有用。
我使用的内核是:
5.8.0-45-generic
xrandr 的输出是(欠扫描为 2%):
Screen 0: minimum 8 x 8, current 1916 x 1077, maximum 32767 x 32767
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 connected primary 1916x1077+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
1920x1080 60.02*+
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-3 disconnected (normal left inverted right x axis y axis)
DP-4 disconnected (normal left inverted right x axis y axis)
这是 /etc/X11/xorg.conf 的输出:

有人知道这是什么原因造成的,以及如何解决吗?提前谢谢
编辑:线条从底部开始,一直延伸到屏幕的 1/3 左右,那里有点闪烁,然后又从底部开始。在闪烁期间,如果你仔细听,会听到笔记本电脑内部电源按钮周围发出像苍蝇的声音。
