Linux Mint suddenly lagging

Post by TheDomesticUser » Sun Nov 10, 2019 4:20 pm

For the past few hours, my laptop has been heavily lagging while I'm on Linux Mint. It has never happened before and I only installed Linux Mint with dual boot alongside Windows 10 Home about a month ago. Does anyone have any solutions?

Please post an inxi -Fxz report. This will give us a concise overview of your hardware and on how Mint sees it.

Here is how to generate the report and post it:

Boot from your installation media (USB/DVD)
Open a terminal window (Ctrl-Alt-t). Make it fullscreen to avoid unneeded linebreaks or chopped lines. Execute the command

Code: Select all

 inxi -Fxzd 
exactly as it has been typed here.

Mark the complete text output which the command will display with your mouse.
Press the keyboard shortcut <Shift><Ctrl>C to copy the marked text into the clipboard.
Enclose the results between the code markers by selecting </> from the mini toolbar above the textbox where you type your reply then paste <Ctrl>V them in your reply between the code markers.

The results will help us to help you.

Try this:
Update Manager - panel: View - Linux kernels
Install the latest kernel of the 5.3 series. Then reboot.

Did you start a new application? Did you open a huge number of pages in a Web browser? You can watch memory usage build up after a boot by using System Monitor. The lag might start when memory runs out and paging starts.

Check your disk for errors by looking at the SMART data for that disk in the Disks program.
