The Screen Remains Black After Suspending: High Xorg CPU Usage

Introduction

Have you ever encountered the frustrating issue of your screen remaining black after suspending your system? This perplexing problem is often accompanied by unusually high CPU usage from the xorg process. In this article, we will delve into the possible causes and solutions for this issue, providing you with a clear understanding of what might be happening and how to resolve it.

Understanding the Black Screen Issue

Identifying the Culprit: Xorg

When your screen stays black after suspending, it is crucial to determine the cause. In many cases, the xorg process is found to be consuming excessive CPU resources. Xorg, also known as X Window System, is responsible for managing graphical display and user input on Linux systems. When it encounters high CPU usage, it can lead to various display-related issues, including a black screen upon resuming from suspension.

The Perplexity of the Black Screen Issue

The black screen problem after suspending can be perplexing for many users. The sudden loss of display can leave you feeling puzzled and frustrated. However, understanding the possible reasons behind this issue can help you take appropriate action to resolve it.

The Burstiness of High Xorg CPU Usage

High CPU usage by the xorg process is often characterized by bursts of intense activity. This burstiness can cause sudden spikes in CPU usage, leading to system slowdowns and display-related problems. Recognizing this burstiness can assist in diagnosing the root cause of the black screen issue.

Possible Causes and Solutions

Outdated Graphics Drivers

One common cause of the black screen issue is outdated or incompatible graphics drivers. As new software updates are released, older drivers may struggle to keep up, resulting in various display abnormalities. To address this, ensure that you have the latest graphics drivers installed for your system. Check the manufacturer's website or utilize driver update tools to find and install the appropriate drivers.

Power Management Settings

Misconfigured power management settings can also contribute to the black screen problem. When your system enters suspension, it might encounter difficulties in resuming due to incorrect power management configurations. To resolve this, navigate to your system's power settings and double-check that the settings are optimized for proper suspension and resumption.

Hardware Incompatibilities

Some hardware configurations may clash with certain software or drivers, causing the black screen issue. Incompatibilities can arise due to a variety of factors, such as conflicting firmware or outdated BIOS. It is advisable to consult your hardware manufacturer's support documentation or forums to check for any known compatibility issues and obtain appropriate solutions.

Resource-Intensive Applications

Resource-intensive applications can strain your system's resources, including the xorg process. When you suspend your system and resume it with these applications still running, it can lead to increased CPU usage and a black screen. Closing resource-heavy applications before suspending can help prevent this issue.

Conclusion

Encountering a black screen after suspending your system can be a frustrating experience, especially when combined with high xorg CPU usage. By understanding the causes and potential solutions discussed in this article, you are now equipped to troubleshoot and resolve this issue effectively. Remember to keep your graphics drivers up to date, review your power management settings, investigate hardware compatibility, and close resource-intensive applications before suspending your system. Implementing these solutions will help ensure a smooth and hassle-free resumption of your system, with no more black screens.

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
