我最近开始定期使用 Ubuntu，并想找到一种方法来监控我的 CPU 温度。
我按照在线的步骤安装了 lm-sensors 并执行了传感器检测。
这是传感器检测的输出 ->
# sensors-detect version 3.6.0 # System: Dell Inc. Dell G15 5515 [1.5.0] (laptop) # Processor: AMD Ryzen 5 5600H with Radeon Graphics (25/80/0) This program will help you determine which kernel modules you need to load to use lm_sensors most effectively. It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. Some south bridges, CPUs or memory controllers contain embedded sensors. Do you want to scan for them? This is totally safe. (YES/no): Silicon Integrated Systems SIS5595... No VIA VT82C686 Integrated Sensors... No VIA VT8231 Integrated Sensors... No AMD K8 thermal sensors... No AMD Family 10h thermal sensors... No AMD Family 11h thermal sensors... No AMD Family 12h and 14h thermal sensors... No AMD Family 15h thermal sensors... No AMD Family 16h thermal sensors... No AMD Family 17h thermal sensors... No AMD Family 15h power sensors... No AMD Family 16h power sensors... No Hygon Family 18h thermal sensors... No Intel digital thermal sensor... No Intel AMB FB-DIMM thermal sensor... No Intel 5500/5520/X58 thermal sensor... No VIA C7 thermal sensor... No VIA Nano thermal sensor... No Some Super I/O chips contain embedded sensors. We have to write to standard I/O ports to probe them. This is usually safe. Do you want to scan for Super I/O sensors? (YES/no): /dev/port: Operation not permitted Some hardware monitoring chips are accessible through the ISA I/O ports. We have to write to arbitrary I/O ports to probe them. This is usually safe though. Yes, you do have ISA I/O ports even if you do not have any ISA slots! Do you want to scan the ISA I/O ports? (YES/no): /dev/port: Operation not permitted Lastly, we can probe the I2C/SMBus adapters for connected hardware monitoring devices. This is the most risky part, and while it works reasonably well on most systems, it has been reported to cause trouble on some systems. Do you want to probe the I2C/SMBus adapters now? (YES/no): Using driver `i2c-piix4' for device 0000:00:14.0: AMD KERNCZ SMBus Next adapter: Synopsys DesignWare I2C adapter (i2c-0) Do you want to scan it? (YES/no/selectively): Adapter doesn't support all probing functions. Some addresses won't be probed. Client at address 0x2c can not be probed - unload all client drivers first! Next adapter: SMBus PIIX4 adapter port 0 at ff00 (i2c-1) Do you want to scan it? (YES/no/selectively): Next adapter: SMBus PIIX4 adapter port 2 at ff00 (i2c-2) Do you want to scan it? (YES/no/selectively): Next adapter: SMBus PIIX4 adapter port 1 at ff20 (i2c-3) Do you want to scan it? (YES/no/selectively): Next adapter: AMDGPU DM i2c hw bus 0 (i2c-4) Do you want to scan it? (yes/NO/selectively): Next adapter: AMDGPU DM i2c hw bus 1 (i2c-5) Do you want to scan it? (yes/NO/selectively): Next adapter: AMDGPU DM aux hw bus 0 (i2c-6) Do you want to scan it? (yes/NO/selectively): Next adapter: AMDGPU DM aux hw bus 1 (i2c-7) Do you want to scan it? (yes/NO/selectively): Sorry, no sensors were detected. This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.**
即使我对所有问题都输入“是”，最终结果还是相同的。
当我运行传感器时，这是我得到的输出 ->

结果显示 CPU 温度吗？有人能帮我吗？

确保安全启动已禁用
我刚刚遇到了这个问题，并通过在 BIOS 设置中禁用安全启动解决了它。如果您还没有像其他人提到的那样尝试在 root 中运行传感器检测，这可能是您遇到此问题的原因。希望这能有所帮助 :^)
