Laptop lid closing freeze - Ubuntu

Experiencing laptop freeze issues when closing the lid on Ubuntu can be frustrating, but it's a relatively common problem. The cause of this issue can vary, but you can try the following steps to diagnose and potentially resolve it:


1. **Update Your System:** Ensure that your Ubuntu system is up to date by running the following commands in the terminal:

   ```

   sudo apt update

   sudo apt upgrade

   ```


2. **Power Management Settings:** Sometimes, the default power management settings may cause issues when the laptop lid is closed. You can adjust these settings by going to "Settings" > "Power" (or similar, depending on your Ubuntu version). Make sure that the behavior when the lid is closed is set to "Suspend" or "Do Nothing," depending on your preference.


3. **Graphics Driver:** Outdated or incompatible graphics drivers can lead to freezing issues. You can try updating your graphics driver to the latest version. Depending on your graphics hardware, you may use open-source or proprietary drivers. Research the appropriate driver for your system.


4. **Tweak Systemd Configuration (Advanced):** In some cases, you might need to adjust the systemd configuration to handle lid events. Create a configuration file by running the following command:

   ```

   sudo nano /etc/systemd/logind.conf

   ```

   In the file, add or modify the following lines:

   ```

   HandleLidSwitch=suspend

   HandleLidSwitchExternalPower=suspend

   HandleLidSwitchDocked=suspend

   ```

   Save the file, and then restart the systemd-logind service:

   ```

   sudo service systemd-logind restart

   ```


5. **Kernel Parameters:** Some users have reported success by modifying kernel parameters. You can try this by adding or modifying kernel parameters in the `/etc/default/grub` file. For example:

   ```

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash button.lid_init_state=open"

   ```

   After making changes, update the grub configuration:

   ```

   sudo update-grub

   ```


6. **BIOS/UEFI Settings:** Check your laptop's BIOS/UEFI settings for any power management options related to the lid. Sometimes, tweaking these settings can help resolve lid-related issues.


7. **Hardware Compatibility:** Some laptops have hardware-specific issues with Ubuntu, and the Linux kernel might not fully support all features. Check online forums and Ubuntu community resources for information related to your laptop's model.


8. **Kernel Update:** If none of the above solutions work, consider updating your Linux kernel to a newer version. Ubuntu provides tools like UKUU (Ubuntu Kernel Update Utility) to simplify this process.


9. **External Monitors:** If you're using external monitors and your laptop lid closing triggers issues, disconnect external monitors before closing the lid to see if the problem persists.


10. **Logs:** Check system logs for any errors or issues related to the lid events. You can find these in `/var/log/syslog` or by using the `journalctl` command.


If the problem persists, consider reporting the issue on the Ubuntu forums or launchpad.net, where developers and the community may provide more specific advice or solutions based on your hardware and Ubuntu version.


Remember to make backups and use caution when modifying system configurations, especially in advanced settings.

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
