暂停 Ubuntu 20.04.3 LTS 后 NVIDIA 470 驱动程序无法工作

Question

我有 2 台显示器，一台 28 英寸三星 UE590 和一台 24 英寸戴尔。暂停桌面后，我发现只显示DELL显示器，而且分辨率低得多。

\n

我检查了xrandr，但我得到：

\n

xrandr: failed to get size of gamma for output default\n

\n

经过一番调查，我设法让三星 UE590 显示器正常工作，但我必须使用 Nouveau（开源驱动程序），而不是 NVIDIA 470 驱动程序才能做到这一点。这会导致CPU风扇每10秒就大声运转一次，而且整个计算机的反应速度也会变慢，可能是由于显卡驱动程序不兼容造成的。

\n

我尝试运行：

\n

sudo ubuntu-drivers autoinstall\n

\n

并且有这个错误：

\n

\n

之后我尝试使用 NVIDIA 460 而不是 470：

\n

$ sudo apt install nvidia-driver-460\nReading package lists... Done\nBuilding dependency tree       \nReading state information... Done\nnvidia-driver-460 is already the newest version (460.91.03-0ubuntu0.20.04.1).\n0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.\n

\n

我将“活动 \xe2\x86\x92软件和更新\xe2\x86\x92其他驱动程序”设置为nvidia-460。

\n

UE590显示器仍然没有显示任何内容。它仅在使用 Nouveau 时有效。

\n

我想知道如何像以前一样使用NVIDIA驱动程序和UE590显示器。

\n

谢谢！

尝试使用以下命令删除现有的 Nvidia 专有驱动程序：

sudo apt update
sudo apt-get remove '^nvidia'
sudo apt autoremove
sudo reboot 

然后安装新的 Nvidia 专有驱动程序sudo ubuntu-drivers install
