How do I correctly transfer xrandr settings to xorg.conf?

 To correctly transfer xrandr settings to xorg.conf, you will need to create a custom xorg.conf file that includes the desired settings. Here are the steps to do this:


1. **Generate a Template xorg.conf File**:

   If you don't already have an xorg.conf file, you can generate a template using the following command:


   ```bash

   sudo Xorg :1 -configure

   ```


   This command runs a new X server (numbered 1) and generates a sample xorg.conf file in the current directory. You may need to adjust the display number depending on your system.


2. **Edit the xorg.conf File**:

   Open the generated xorg.conf file with a text editor. For example:


   ```bash

   sudo nano /etc/X11/xorg.conf

   ```


3. **Add xrandr Settings**:

   In the `Screen` or `Monitor` section of the xorg.conf file, you can add your desired xrandr settings. For example:


   ```plaintext

   Section "Monitor"

       Identifier "Monitor0"

       Option "PreferredMode" "1920x1080"

   EndSection


   Section "Screen"

       Identifier "Screen0"

       Monitor "Monitor0"

       DefaultDepth 24

       SubSection "Display"

           Modes "1920x1080"

       EndSubSection

   EndSection

   ```


   Replace `"1920x1080"` and other settings with your desired resolution and configuration.


4. **Test the Configuration**:

   After editing the xorg.conf file, you should test the configuration to make sure it works as expected. To test it, you can run the X server with the custom configuration:


   ```bash

   startx -- -config /etc/X11/xorg.conf

   ```


   This command will start the X server with your custom xorg.conf file. If everything is working as expected, you can proceed to the next step.


5. **Make the Configuration Permanent**:

   Once you've verified that the xorg.conf configuration works, you can make it permanent by copying the xorg.conf file to the appropriate location:


   ```bash

   sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.d/xorg.conf

   ```


   This ensures that the custom configuration is loaded at system startup.


6. **Reboot or Restart X Server**:

   To apply the permanent configuration, you may need to reboot your system or restart the X server:


   ```bash

   sudo systemctl restart display-manager

   ```


   Replace `display-manager` with your actual display manager, which could be `lightdm`, `gdm`, `sddm`, or another, depending on your Linux distribution.


By following these steps, you can transfer xrandr settings to your xorg.conf file and make them permanent. However, please exercise caution when editing system configuration files, as incorrect settings can potentially cause display issues.

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
