Thanks a lot, Google AI. Even though I didn’t want you.

Linux Mint can slow down over time due to
high memory usage (RAM saturation), heavy disk read/write bottlenecks, or memory leaks where closed apps don’t release resources. Common causes include thermal throttling from dust/low fans, inefficient GPU drivers, or excessive startup apps. Monitoring with top or htop helps identify the specific bottleneck.
Here are the main reasons for a “slowdown after a while” in Linux Mint:
- Memory Leaks and High Resource Usage: Applications, particularly web browsers, may fail to clear cache and consume more memory over time. If available RAM runs out, the system uses “swap” space on the drive, which is significantly slower.
- Thermal Throttling: If the CPU or GPU fans are clogged with dust, or the thermal paste is old, the computer will overheat and deliberately slow down to prevent damage.
- Window Manager Issues: The Cinnamon desktop environment’s window manager (muffin) can encounter errors or high CPU usage. Removing extensions like “burn-my-windows” or reducing visual effects can improve responsiveness.
- Disk Bottlenecks or Faulty Drive: A failing hard drive (HDD) or nearly full drive will cause system lag. Checking the SMART data in the “Disks” utility can reveal failing drives.
- Startup Applications: Too many apps running in the background from boot, which can be managed in System Settings > Startup Applications.
- Outdated or Missing GPU Drivers: Ensure you are using proprietary drivers, especially for NVIDIA GPUs, found under Driver Manager.
Common Fixes:
- Disable Visual Effects: Go to Preferences > Effects and turn off animations.
- Install Preload: Run
sudo apt install preloadto help applications load faster. - Use
htop: Install and runhtopto identify which process is hogging CPU or RAM. - Clear Cache: Use cleaner tools or restart the system to clear RAM.
