Linux Mint – Troubleshooting Linux Mint

Installing Apache On CentOS 8

As smart as computers are and with as many amazing advancements as we’ve had in recent years, we’re still unable to build computers and software that are not prone to failure. Nowadays, we rely quite a bit on our computers, and when they fail, it can be devastating. Thankfully, Linux Mint is a very stable operating system, but it too has its share of faults. When something happens that prevents us from using our computers, it’s important to get it back up and running as quick as we can. In this final chapter, we will take a look at some common issues that can occur and what we can do about them.

In this chapter, we will discuss the following topics:

  • Performing the initial triage
  • Troubleshooting in the Software Rendering Mode
  • Diagnosing boot issues
  • Recovering data
  • Perusing system logs
  • Reinstalling GRUB
  • Testing the RAM
  • Pinpointing audio issues
  • Solving problems with networking
  • Solving slow frame rates in games
  • Getting help from the community

Performing the initial triage

Before we go over some common issues and their solutions, there are some important, catch-all steps that can be performed in the face of a problem. You never know, one of these steps might just work.

For starters, if you run into a software-related issue on your Linux Mint computer, there’s always a chance that the issue you’re experiencing may not have anything to do with your computer or your installation at all; you may be experiencing a software bug. For this reason, you’d be surprised at how updating all of your packages often may solve issues. The reason is that perhaps the developers of the application you’re having trouble with noticed the issue already and submitted a fix for it. If you use a newer version of the package, it may include a patch that fixes the problem you’re having. Even if your graphical environment fails to load, you can still update your system using the shell with the following command:


sudo apt-get update && sudo apt-get dist-upgrade

Before you confirm any changes, take a gander at the output to see what the package manager wants to update before agreeing to it. If the application you’re having an issue with is listed, it may be exactly what you need. Proceed with the updates and then restart the offending application. The apt-get command, mentioned earlier, will work on any Mint system even if the graphical environment doesn’t load. If you normally use Wi-Fi for your network connection, you may need to connect an Ethernet cable to your computer in order to obtain a connection, in case your graphical environment fails.

Although it may seem like common knowledge, sometimes restarting your entire system may help if you experience issues. While this doesn’t fix issues very often, you never know. In other cases, sometimes killing a service and then restarting it may get things rolling again.

Another important tactic to learn is to use Google. This too may seem like silly common knowledge, but the fact is that there’s a small statistical chance that you’ll end up being the first and/or only person to encounter a specific issue. If you search Google for the issues you are facing, you may stumble upon an online forum posting with someone mentioning your exact problem; this can result in a solution after the community weighs in on the problem. In other instances, you may instead find a bug report that will at least tell you whether or not your issue is beyond something you can fix and is being looked at by those responsible for it. If you need to, you can also post a forum message yourself on sites such as linuxquestions.org or on Mint’s own forums. However, be forewarned; members of Linux communities have a very uncanny ability to easily sniff out those that have done very little research on their own before asking for help. Do the best you can, and then ask for assistance if you need to.
