Linux Mint 18 Mate memory leak

You may experience your Mint 18 Mate occasionally getting slow and non-responsive, with Mate panel freezing or mouse pointer moving slowly and in jerky fashion.

If you run top, you see that that CPU usage is constantly up, with mate-settings-daemon hogging close to 100%.


  • tail -f .xsession-errors

If you see something like “unable to create file ‘/run/user/1000/dconf/user’: Permission denied.  dconf will not work properly.”, a memory leak causing bug may be at fault.

The bug makes wrong permissions to be assigned to the file /run/user/1000/dconf/user , making it non-writable for your processes.

Fix it as root by making the respective user to own the file respective file, e.g. /run/user/1000/dconf/user , and killing and restarting the mate-settings-daemon .
