22.04 Laptop Monitor Randomly Freezes

$

I have a XPG Xenia-14 laptop that I have been using Ubuntu 22.04 for a while now on. My typical setup is 2 external monitors and my laptop monitor as a third running through VisionTek VT7100 docking station.

Recently my laptop screen will start to freeze but my external monitors can still be used. I can't drag anything to my laptop monitor either. The only fix so far is to hard reset it by holding the power button down or pressing the power the button to get the confirmation box to appear to restart or shutdown which seems to unfreeze the monitor. Nothing will happen to indicate that its frozen but suddenly it just becomes unusable.

Some system details:

Troubleshooting:

  • reboot several times
  • run sudo apt-get update && sudo apt-get upgrade
  • Cleared apt cache with sudo apt-get clean--dry-run
  • Free up some space and remove residual files with sudo apt-get autoremove and sudo apt-get autoclean

Any thoughts on what it could be or ways to fix it?
