我有 2 台顯示器，一台 28 吋三星 UE590 和一台 24 吋戴爾。暫停桌面後，我發現只顯示DELL顯示器，而且解析度低得多。
我檢查了xrandr，但我得到：
xrandr: failed to get size of gamma for output default
經過一番調查，我設法讓三星 UE590 顯示器正常工作，但我必須使用 Nouveau（開源驅動程式），而不是 NVIDIA 470 驅動程式才能做到這一點。這會導致CPU風扇每10秒就大聲運轉一次，而且整台電腦的反應速度也會變慢，可能是由於顯示卡驅動程式不相容造成的。
我嘗試運行：
sudo ubuntu-drivers autoinstall
並且有這個錯誤：
WARNING:root:_pkg_get_support nvidia-driver-390: package has invalid Support Legacyheader, cannot determine support level

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:
The following packages have unmet dependencies.
linux-modules-nvidia-470-generic-hwe-20.04 :
Depends: linux-modules-nvidia-470-5.11.0-38-generic (= 5.11.0-38.42~20.04.1) but it is not going to be installed
Depends: nvidia-kernel-common-470 (>= 470.74) but 470.63.01-0ubuntu0.20.04.2 is to be installed
E: Unable to correct problems, you have held broken packages.
之後我嘗試使用 NVIDIA 460 而不是 470：
$ sudo apt install nvidia-driver-460
Reading package lists... Done
Building dependency tree
Reading state information... Done
nvidia-driver-460 is already the newest version (460.91.03-0ubuntu0.20.04.1).
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
我設定了活動→軟體和更新→額外的驅動程式到英偉達-460。
UE590顯示器仍然沒有顯示任何內容。它僅在使用 Nouveau 時有效。
我想知道如何像以前一樣使用NVIDIA驅動程式和UE590顯示器。
謝謝！

嘗試使用以下命令刪除現有的 Nvidia 專有驅動程式：
sudo apt update
sudo apt-get remove '^nvidia'
sudo apt autoremove
sudo reboot
然後安裝新的 Nvidia 專有驅動程式sudo ubuntu-drivers install
