我的电脑上有 2 个显卡。一个是 GTX Titan Xp，另一个是 ASUS TUF RTX 4090。我想调整 4090 的风扇速度，但出现了一些错误。操作系统是 Ubuntu 22.04。以下是详细信息。
这是我运行后得到的结果nvidia-smi：

我们可以看到系统可以读取 Titan Xp 风扇速度，但报告 4090 错误。这是命令的输出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'
重新启动后，如果我运行命令sudo nvidia-settings -a "[gpu:1]/GPUFanControlState=1" -a "[fan:1]/GPUTargetFanSpeed=55"，它会报告错误：
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: An internal driver error occurred
ERROR: Error assigning value 55 to attribute 'GPUTargetFanSpeed' (RyzenTR:0[fan:1]) as specified in assignment '[fan:1]/GPUTargetFanSpeed=55' (Unknown
Error).
我尝试在终端中重新安装 nvidia 驱动程序，但问题并未解决。有办法解决这个问题吗？
