我运行 Kubuntu 20.04 LTS。我的问题是 Nvidia X 服务器设置不会保存我的配置。我已经尝试了很长时间才能保存它，但我无法弄清楚为什么它不会。我发现很多人有同样的问题，但我找不到解决方案。我不是Linux专家，所以我希望有人能提供帮助。
我已经看到，在Thermal 设置下，GPU 风扇速度由Control Type: Variable管理。理想的情况是我可以修改变量的设置，以使 GPU 风扇在不同温度下以我想要的负载运行。
如果那是不可能的，那没关系；我手动设置了 GPU 风扇，但问题是每次我注销或重新启动 PC 时，手动设置都会重置，我每次都必须重新配置它。
我想提高我的风扇速度，让我的电脑运行得更冷一些，所以我下载了“fancontrol”包并运行了传感器检测和 pwmconfig 程序。但即使在阅读了“fancontrol”的手册页之后，我也不知道某些参数的实际数值是什么。
例如，有“MINSTART”和“MINSTOP”参数设置“风扇开始旋转的最低速度。你应该使用一个安全的值来确保它工作，即使风扇变老了”和“最低速度风扇仍在旋转。在这里也使用一个安全的值。但是“MINSTART”和“MINSTOP”的度量单位是什么？
然后它说“MINPWM”和“MAXPWM”是分别在温度低于 MINTEMP 或高于 MAXTEMP 时使用的“PWM”值。它确实说“当未定义“MINPWM ...速度）。”但是当我运行“pwmconfig”并选择“详细关联”选项时，我可以看到 255不是最大速度；相反，它大约是速度的一半（是的，我试过等待几分钟让风扇旋转，因此这种行为不仅仅是开始测试和测量之间的滞后时间的产物），然后 210 的值是在“
PWM 255 FAN 1066
PWM 240 FAN 974
PWM 225 FAN 1366 (probably incorrect)
PWM 210 FAN 1650 (probably incorrect)
PWM 195 FAN 1558 (probably incorrect)
PWM 180 FAN 1442 (probably incorrect)

PWM 150 FAN 1198 (probably incorrect)
PWM 135 FAN 1066

PWM 105 FAN 974
... some output omitted (PWM values under 150 consistently produce slow speeds)....
Warning: slow font initialization Hit return to continue...qt_processTermEvent received a GE_fontprops event. This should not have happened
风扇一直旋转到全速，然后我开始这个阶段的测试，然后风扇速度立即下降，然后加速，然后再次下降。（这是针对“hwmon1/pwm1”传感器的。对于“hwmon1/pwm3”传感器来说，有一个更加戏剧性和看似随机的效果。）（最后的错误信息是新的。）
无论如何，当我使用 fancontrol 程序（使用默认配置或“pwmconfig”生成的配置）时，它肯定会影响风扇的速度，但很难说在后台运行 fancontrol 服务是否会更快，或者没有它。
那么“PWM”数字是什么意思呢？从漫不经心的谷歌上搜索，它似乎与风扇的电脉冲周期有关，这就引出了一个问题：哪个 PWM 数字真的是最大速度？我假设 190 到 220 之间的数字会产生一个波形，使电机旋转得更快，但这个数字的真正含义是什么？以及如何将风扇配置为按需以更高的速度运行？
我已经fancontrol安装了，运行后立即pwmconfig收到一条Configuration appears to be outdated, please run pwmconfig again消息。
这是我安装了 Ubuntu 16.04 的旧戴尔 PC (i5-2320)。一些输出：

#pwmconfig revision 6243 (2014-03-20)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
Found the following devices:
hwmon0 is coretemp
hwmon1 is dell_smm
Found the following PWM controls:
hwmon1/pwm1 current value: 255
hwmon1/pwm2 current value: 255
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon1/fan1_input current speed: 3191 RPM
hwmon1/fan2_input current speed: 0 ... skipping!
Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!

No correlations were detected.
There is either no fan connected to the output of hwmon1/pwm2,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,
check out the hardware database on http://www.almico.com/forumindex.php)
Did you see/hear a fan stopping during the above test (n)? n
Testing is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes

我从一个autogen配置开始，但是当我无法开始时fancontrol做了一些事情 - 删除了所有引用，pwm2因为我只有一个我试图控制的单个 cpu 风扇......我添加了后面的值hwmon1（斜体）我自己，因为以前什么都没有。即使我在运行风扇控制时接受这些值，我也会得到

奇怪的是，详细的相关性pwmconfig会改变风扇速度，所以它似乎应该具备所需的一切......但我仍然必须在DEVPATHfor中输入值hwmon1。似乎应该将DEVPATH值与某些东西进行比较，但我不知道是什么。同样，这个问题都在同一个会话中，我还没有重新启动。有什么想法吗？
我有一台双启动的华硕 TP301UJ 笔记本电脑，我的风扇一直很响。我正在尝试在 Ubuntu 中配置我的风扇速度（我在 Windows 10 中很容易做到），但我遇到了问题。
这是我所做的：
我安装了lm-sensors、psensor和fancontrol。psensor运行良好，并读取了风扇速度和所有温度。
Ransudo sensors-detect只说我需要将coretemp添加到/etc/modules. coretemp已经在模块中，所以我什么也没做。
重新启动。跑sudo pwmconfig，它输出：
找到以下设备：
hwmon0 is acpitz
hwmon1 is coretemp
hwmon2 is asus找到以下 PWM 控件：
hwmon2/pwm1 当前值：0hwmon2/pwm1 当前设置为自动速度控制。
一般来说，自动模式比手动模式更受欢迎，因为它更有效并且反应更快。您确定要将此输出设置为手动控制吗？(n)
输入“y”，输出为：
给粉丝一些时间来达到全速...
发现以下风扇传感器：
hwmon2/fan1_input 当前速度：0 ... 跳过！
没有工作风扇传感器，所有读数均为 0。确保连接了 3 线风扇。
您可能还需要增加风扇除数。
有关更多信息，请参阅 doc/fan-divisors。
所以我的风扇进入“手动模式”并开始全速运行但pwmconfig退出，让我的风扇全速运行。将数字/sys/class/hwmon/hwmon2/pwm1_enable从 1 更改回 2，使其再次自动。
这是我的问题（我认为）：当我的风扇处于“手动模式”时，sensors显示-1为它的速度。它没有被检测到！但是在自动模式下，完全没有问题。这使我无法使用pwmconfig.
我已经尝试添加acpi_enforce_resources=lax到 grub 文件中的变量GRUB_CMDLINE_LINUX_DEFAULT。结果是一样的。
我应该怎么办？
在我的带有 i5-8265U CPU 的 Lenovo Yoga 730-15IWL 上，该sensors-detect命令无法检测到风扇，因此sensors也无法显示它们。
如何在这样的系统上显示风扇速度？
我最近从 Windows 迁移到 Ubuntu(18.04.2 LTS) 64 位，因为 Windows 最近一直很臃肿。我想控制我的 GPU（ATI Radeon HD5970 2Gb）风扇的速度，因为它在负载下会很快变热，我想手动设置一个高恒定速度。我尝试在终端上使用sensors 命令，但它没有显示RPM，也不允许我更改它，而且我还听说有一个名为AMDOverdriveCNTRL 的实用程序，我已经从Sourceforge 下载了deb 文件但是当我使用包安装程序安装它看起来好像它已安装（显示百分比，然后说 100%），但在完成后它再次显示为安装。请帮助我解决这种情况。
我使用 apt 安装了 i8kutils，其中安装acpi了tclx8.4. 安装结束的那一刻，粉丝们开始表现得很奇怪，所以我手动卸载了 i8kutils、acpi 和 tclx。
现在，我的计算机每分钟都有频繁的毫秒持续时间冻结。我应该如何解决这个问题？
谢谢。
我试图让我的粉丝在运行 Ubuntu 18.10 的 ASUS B350M M/B 上得到控制。风扇100%不间断运行，运行Windows时当然不存在这个问题。我已经为 fancontrol 设置了 pwmconfig。我尝试使用 pwmconfig 自动生成 fancontrol 配置文件，并且尝试编辑配置文件，希望能够在没有运气的情况下解决此错误。当我运行时，sudo fancontrol我总是得到以下输出：
Loading configuration from /etc/fancontrol ...
grep: /etc/fancontrol: Is a directory

Some mandatory settings missing, please check your config file!
所以问题似乎是我的配置文件显然缺少一些“强制性设置”，但据我所知不是。我保存为 /etc/fancontrol/pwmcfg.gvA0m0UuMG 的 fancontrol 配置文件包含以下内容：
# Configuration file generated by pwmconfig, changes will be lost

MINSTART=hwmon0/pwm1=150 hwmon0/pwm3=190
MINSTOP=hwmon0/pwm1=0 hwmon0/pwm3=90
有没有人有任何可能适用于这种情况的想法或解决方法？我的目标是让风扇控制正常工作，以便我的粉丝能够以合理的速度工作。
我的笔记本电脑风扇很烦人。它旋转 5 秒，然后停止 2 秒，然后旋转，然后反复停止。它总是让我烦恼。我使用传感器包来检查发生这种情况的时间。我意识到当 cpu 温度低时，例如 50 到 55 度，它就会发生。我的意思是当 cpu 正在处理繁重的进程时，风扇正在不停地工作。完全没有过热问题。所以你遇到了问题。
在 bois 中，只有“风扇始终工作”，风扇控制是或否选项。bois 中没有关于风扇的其他选项或信息。将选项更改为是或否对我的问题没有影响。
这是sensors-detect的输出

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.

safe though. Yes, you do have ISA I/O ports even if you do not have any

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.

所以朋友，你有什么解决这个问题的建议？
