I run a program (DingTalk) in Wine on Ubuntu, and because there are some lingering compatibility issues I find a lot of error messages about compiz in journalctl. There are several errors every second.

The issues are not bad enough to prevent me from using the program, but the spammy error messages fill up a lot of disk space, causing older logs to very quickly get deleted to prevent my drive from filling up. I've already allowed several GB of storage for journal files and don't want to just give it more space to fill with the error messages.

Is it possible to configure things so that these compiz errors do not get logged to the journal? I don't know if this is a configuration to be made in compiz, or in Wine.

System details:

  • Ubuntu 20.04
  • wine-8.21 (Staging)
  • Compiz 0.9.14.1

Examples of these errors:

Mostly it is one of these, spammed frequently:

I found the solution to my own problem. I was finally able to prevent the logging with these steps:

  1. Use pidof compiz to find the process ID of compiz
  2. sudo systemctl status [the PID] to find the service that is running compiz. For me running this pulled up user@1000.service.
  3. Scroll down the CGroup section to find the user-level service running compiz. For me, this was unity7.service.
  4. systemctl --user [the user-level service]. This will show the location of the .service file after Loaded:
  5. Add StandardOutput=null and StandardError=null after [Service] inside the corresponding .service file.
