Very high Xorg memory usage with Ubuntu 18.04

  • 772

I'm having a memory leak issue with Xorg and it's taking up huge portions on my memory. Right now, it's up to 41.2% of memory and I haven't even been using the computer that much.

This is some output regarding it.

All drivers are updated as well. Restarting will reset the memory usage but it still creeps up over time.

  1. UPDATE:

    I managed to figure out that the issue was a custom wallpaper systemd service that I was running to update the wallpaper every 30 seconds using pscirlce. Apparently I misconfigured the service and it wasn't removing something from memory properly. I don't know the exact cause of the issue, but removing this fixed my issue.

    Unfortunately I lost the .service files so I don't have any more information for further research.
