我的電腦上有 2 張顯示卡。一個是 GTX Titan Xp，另一個是 ASUS TUF RTX 4090。作業系統是Ubuntu 22.04。這是詳細資訊。
這是我透過運行得到的nvidia-smi：

我們可以看到系統可以讀取 Titan Xp 風扇速度，但報告錯誤 4090 sudo nvidia-xconfig --cool-bits=4。
Using X configuration file: "/etc/X11/xorg.conf".
Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'
重新啟動後，如果我執行 command sudo nvidia-settings -a "[gpu:1]/GPUFanControlState=1" -a "[fan:1]/GPUTargetFanSpeed=55"，它會報告錯誤：
ERROR: An internal driver error occurred
Attribute 'GPUFanControlState' (RyzenTR:0[gpu:1]) assigned value 1.
ERROR: An internal driver error occurred

ERROR: An internal driver error occurred

Error).
我嘗試在終端機中重新安裝 nvidia 驅動程序，但沒有解決問題。有辦法解決這個問題嗎？
