Installed Mint, mouse and keyboard lagging from update

[MorePower!]

On this new install of linux mint, my mouse and keyboard worked fine at first. Then I ran all the updates. Now there seems to be input lag. When I type I can't go fast because the input misses 1 out of 6 keystrokes. And the mouse is slow and stuttery. My cpu is not being overused. I checked in HTOP. I'm a super newb when it comes to linux. Any help is appreciated.

It fixed the next time I started the pc.

Post-install upgrades usually require reboots. Also be prepared to need to reboot next time you run a system upgrade (`sudo apt update && sudo apt upgrade`). You can also enable auto-update to check for updates & install them every so often.

Input lag issues after updating Linux Mint can be frustrating, but there are a few steps you can take to troubleshoot and resolve the problem:

1. Check for Hardware Drivers:​

• Sometimes updates can affect the drivers for your mouse and keyboard. Open the Driver Managerin Linux Mint:
  • Go to Menu > Administration > Driver Manager.
  • Let it search for available drivers and see if there’s a proprietary driver you can use, especially if you're using a USB dongle or wireless input devices.

2. Test a Different Kernel:​

• Updates might have installed a newer kernel, which could be causing the input lag. You can try booting into an older kernel to see if the issue persists:
  • Reboot your system and hold down the Shift key to bring up the GRUB menu.
  • Select Advanced options for Linux Mint.
  • Choose a previous kernel version and see if the input lag issue is resolved.

3. Check for Conflicting Software:​

• Some background processes or software might be causing the lag. Try the following:
  • Open a terminal and run top or htop again to see if any process is spiking in usage when you experience the lag.
  • Disable any non-essential startup applications by going to Menu > Startup Applications and unchecking unnecessary items.

4. Adjust Input Device Settings:​

• If the problem persists, try adjusting the settings for your mouse and keyboard:
  • Go to Menu > Preferences > Mouse and Touchpad and see if adjusting the sensitivity or acceleration helps.
  • Similarly, you can adjust keyboard settings in Menu > Preferences > Keyboard.

5. Try a Different USB Port:​

• If you’re using USB input devices, try plugging your mouse and keyboard into different USB ports. Sometimes the port or hub might cause issues.

6. Look for Updates or Rollback:​

• It’s possible that a recent update introduced a bug. You can check for further updates that might fix the issue:
  • Run sudo apt update && sudo apt upgrade in the terminal to ensure you have the latest patches.
• If the issue started right after a specific update, you might want to consider rolling back that update using the Update Manager:
  • Open Update Manager, click on View > Linux Kernels, and revert to an earlier version if needed.

7. Reinstall Input Drivers:​

• You can also try reinstalling the drivers for your input devices:
  • Run sudo apt-get install --reinstall xserver-xorg-input-all in the terminal to reinstall input drivers.

8. Check for Specific Bug Reports:​

• Sometimes, specific versions of Mint or certain hardware combinations can have known issues. Checking forums or Mint’s official bug tracker might give you a solution.

If none of these steps work, you may want to consider posting detailed information about your hardware (e.g., keyboard/mouse model, connection type, etc.) on Linux Mint forums for more specific advice.
