Ubuntu及衍生发行版CPU/GPU温度达90-92℃时自动挂起问题求助

Hey there, sorry to hear you're stuck with this frustrating automatic suspend issue when gaming on Ubuntu and its derivatives like KDE Neon! Let's dive straight into fixing the suspend trigger since you've made it clear you don't want to focus on overheating right now.

方法1：调整热守护进程（thermald）的配置 #

Ubuntu uses thermald by default to handle thermal events, which might be triggering the suspend at that 94℃ threshold. Here's how to tweak it:

• First, check if thermald is running with this command:

  systemctl status thermald
  

• Edit its configuration file with root privileges:

  sudo nano /etc/thermald/thermal-conf.xml
  

• Look for <Trip> sections in the file. You'll likely find an entry where the type is critical or hot, and the action is set to Suspend. You can either:
  1. Change the temperature value to a higher threshold (e.g., 100000 for 100℃, since the value is in millidegrees Celsius), or
  2. Replace the Suspend action with something less disruptive like Throttle.
• Save the file (Ctrl+O, then Enter in nano) and exit (Ctrl+X), then restart the service to apply changes:

  sudo systemctl restart thermald
  

方法2：修改systemd-logind的温度设置 #

Another place where Ubuntu might enforce thermal suspend is in systemd-logind:

• Open the logind configuration file:

  sudo nano /etc/systemd/logind.conf
  

• Look for lines starting with #ThermalSuspendTemperature= or #ThermalPowerOffTemperature=. Remove the # to uncomment them, then set a higher temperature value (e.g., 100 for 100℃).
• Save and exit the file, then restart the logind service. Note: This might log you out immediately, so save any open work first!

  sudo systemctl restart systemd-logind
  

方法3：检查BIOS/UEFI设置 #

Sometimes the suspend trigger is actually coming from your laptop's firmware, not the OS. Restart your laptop and enter the BIOS/UEFI setup (usually by pressing F2, F10, or Del during boot). Look for sections like Thermal Management or Power Settings—there might be an option for "Thermal Suspend Temperature" that you can adjust to a higher value or disable entirely.

A quick note: Even though we're focusing on fixing the suspend issue right now, running your GPU at 94℃ for extended gaming sessions isn't ideal for its long-term health. It's worth keeping that in mind for future tweaks!
