How to change screen/display resolution in Ubuntu 9.10

If you’re running Ubuntu 9.10 and want to tweak your display settings, adjusting the screen resolution is a quick fix. Whether you’re trying to match your monitor’s native resolution or just make things look sharper, Ubuntu 9.10 has tools to help you get it done. Let’s walk through the steps to change the screen resolution, troubleshoot common issues, and customize your display for a better experience.

Accessing Display Settings

The first step to change your screen resolution is to access the Display Settings. Here’s how:

1. Click on System in the top menu bar.
2. Navigate to Preferences and select Display.
3. The Display Preferences window will open, showing your current resolution and other options.

From here, you’ll be able to pick a resolution that works best for your screen.

Choosing the Right Resolution

• Native Resolution: For the best clarity, choose the native resolution of your monitor (usually noted in the manual or on the manufacturer’s website).
• Lower Resolutions: If your system feels sluggish, dropping the resolution can improve performance, but it may make things look less crisp.

Adjusting Screen Resolution via Terminal

If the graphical interface doesn’t show the resolution you need, you can use the terminal to make adjustments. Follow these steps:

1. Open a terminal window by pressing Ctrl + Alt + T.
2. Type the following command to list available resolutions: xrandr This will display a list of supported resolutions for your current setup.
3. To set a new resolution, use the following command: xrandr --output [display-name] --mode [resolution] Replace [display-name] with the name of your display (e.g., VGA1 or HDMI1) and [resolution] with your desired resolution (e.g., 1920×1080).
4. If the desired resolution is not listed, you may need to add it manually: cvt [width] [height] xrandr --newmode "custom-resolution" [output] xrandr --addmode [display-name] "custom-resolution" xrandr --output [display-name] --mode "custom-resolution" Replace [width] and [height] with the resolution dimensions you want.

Fixing Common Problems

Sometimes, you might run into issues when changing the resolution. Here are a few quick fixes:

• Resolution Missing in Settings: Use the terminal method to manually add the resolution.
• Changes Revert After Reboot: Add the xrandr command to your startup applications. Open System > Preferences > Startup Applications, click Add, and enter your xrandr command.
• Display Not Detected: Check your cable connections, update your graphics drivers, or try switching to a different cable type (like HDMI or VGA).

Customizing Your Display for the Best Experience

After setting your resolution, you might want to tweak other display settings to optimize your experience:

• Adjust the refresh rate for smoother visuals.
• Configure dual monitors under the Display Preferences if you’re using more than one screen.
• Change the font size or scaling settings for better readability on high-resolution displays.

Wrapping Up

Changing the screen resolution in Ubuntu 9.10 can make a big difference in how your system looks and feels. Whether you’re using the graphical interface or terminal commands, you have plenty of options to get things just right. Don’t forget to experiment and find the setup that works best for your hardware.
