Compiz is a popular window manager used in many Linux distributions to enhance the visual experience of the desktop environment. However, if you are a Wine user, you might have noticed that Compiz generates a lot of spam in the journalctl logs. This can be quite annoying and make it difficult to find other important system messages. In this article, we will explore how to prevent Compiz spam in journalctl due to Wine.
Understanding the Issue
When running Windows applications through Wine, Compiz often generates a large number of log messages. These messages can flood the journalctl logs, making it challenging to find relevant information. The spam generated by Compiz can include messages related to unsupported or unimplemented functions in Wine, as well as other debugging information.
While these messages are important for developers and Wine contributors, they are typically not relevant for regular users. Therefore, it is desirable to filter out these spam messages and only display the necessary system logs.
Filtering Compiz Spam in journalctl
To prevent Compiz spam in journalctl due to Wine, we can use the filtering capabilities of the journalctl command. By applying filters, we can exclude the unwanted log messages from the output.
Here is an example command that filters out the Compiz spam:
journalctl -p 3 --no-pager | grep -v "compiz"
Let's break down this command:
journalctl: This command is used to query and display the contents of the systemd journal.-p 3: This option filters the log messages based on their priority level. In this case, we are only interested in messages with a priority level of 3 or higher, which excludes the debug messages generated by Compiz.--no-pager: This option prevents the output from being piped into a pager program, allowing us to see the complete log messages directly in the terminal.grep -v "compiz": This command filters out any log messages that contain the word "compiz". The-voption ingrepmeans "invert match", i.e., exclude the lines that match the pattern.
By running this command, you will only see the relevant system log messages without the Compiz spam. You can also create an alias or a shell script to make it easier to use this command whenever needed.
Automating the Filtering Process
If you find yourself frequently needing to filter out the Compiz spam in journalctl, you can automate the process by creating a systemd unit file.
Here are the steps to create the systemd unit file:
- Create a new file named
compiz-filter.servicein the/etc/systemd/system/directory. - Edit the file and add the following content:
[Unit]
Description=Filter Compiz spam in journalctl
[Service]
ExecStart=/bin/sh -c "journalctl -p 3 --no-pager | grep -v 'compiz'"
StandardOutput=syslog
[Install]
WantedBy=multi-user.target
- Save the file and exit the text editor.
- Run the following command to reload the systemd configuration:
sudo systemctl daemon-reload
- Finally, start the new service by running:
sudo systemctl start compiz-filter
Now, the Compiz spam will be automatically filtered out from the journalctl logs whenever the system is restarted or the service is manually started.
Preventing Compiz spam in journalctl due to Wine can significantly improve the readability of system logs for regular users. By applying filters or automating the filtering process using a systemd unit file, you can exclude the unwanted log messages and focus on the relevant system information.
