In this tutorial, we'll see how to solve Random Freezes in Linux Mint. Linux Mint freezes randomly mainly due to several reasons:

  • CPU
  • hardware issues
  • Kernel/Bios

Let's check different solutions and ideas.

Pro Tip 1
Updating Kernels, BIOS and other settings is a risky operation. Do a back up in order to prevent data loss.
Pro Tip 2
Frequent freezes might suggest hardware problems.

Note: Sometimes USB devices are not responding - which reminds the Linux Mint freezing issue but it's not.

Step 1: Check system info

To start solving the problem, we need to find information about the Linux Mint system. We can use command:

inxi -Fzx

Which is recommended when you need help and post in Linux Mint forums. The output is:

We can notice two important things:

  • CPU is AMD Ryzen 7 1700
  • GPU is GeForce GTX 1080
  • Kernel version - 5.4.0-125-generic
  • Desktop - Cinnamon 5.2.7
  • Distro: Linux Mint 20.3 Una

They are needed in the next steps.

Alternatively we can check this information on Linux Mint System Info:

  • Main Menu
  • Preferences
  • System Info

Step 2: Check Linux Mint Logs

Next we need to check the logs for errors and clues for potential hardware or system issues.

  • Main Menu
  • Administration
  • Logs
  • Select the Period on top
  • Select category:
    • System
    • Hardware
    • All

Step 3: Update Linux Mint Kernels

Next step is to update the kernels. We can check kernels in Linux Mint by command:

uname -r



Change of the Kernel version might resolve the issues in Linux Mint.

To update kernels we can follow the next steps:

  • Main menu
  • Administration
  • Update Manager
  • go to option View from the menu
  • click Linux kernels (accept the warning)
  • select and install new kernel
  • reboot

It may take several days to check the new kernel and if the freezing problems are solved.

Step 4: Change GPU driver

Sometimes the freezing problems in Linux Mint are related to the GPU driver or sound devices.

Step 5: Fix random freeze on Intel CPU

Some Intel CPUs suffer from random system freezes. To fix that issue we can reduce the maximum sleep state of the CPU by:

  • open terminal
  • check current Max C-state by
    • cat /sys/module/intel_idle/parameters/max_cstate
  • update Max C-state by
    • xed admin:///etc/default/grub
  • find and delete line - GRUB_CMDLINE_LINUX=""
  • replace by GRUB_CMDLINE_LINUX="intel_idle.max_cstate=1"
  • save changes
  • run command
    • sudo update-grub
  • reboot

Final we can verify the change by:

cat /sys/module/intel_idle/parameters/max_cstate

expected value is 1.

Step 6: Solve random freeze on AMD CPU

6.1 Change BIOS - PSU Idle Control

First we can change the PSU Idle Control setting in BIOS.

For older versions you may need to update the BIOS. Sometimes it might be named - Power Supply Idle Control.

We need to change this option to:

Typical Current Idle

6.2 Change GRUB parameters

To fix random freezes in Linux Mint related to AMD CPUs we can follow next steps:

  • open Linux terminal
  • Run command
    • xed admin:///etc/default/grub
  • find line - GRUB_CMDLINE_LINUX=""
  • Add idle=nomwait to become as:
    • GRUB_CMDLINE_LINUX="idle=nomwait"
  • save changes
  • run command - sudo update-grub
  • reboot

Your system should be more stable right now.

Step 7: Update BIOS

Usually updating BIOS will bring new features, fixes, better performance and a stable system.

Update process has several steps:

  • Prepare USB flash
    • Fat32 works better in most cases
  • Find and download BIOS update
  • Update BIOS

Sample process for MSI board:
