🤔 What Are Graphics Issues?

Graphics issues happen when your screen doesn’t work right. It’s like your computer can’t talk to your monitor properly.

Common graphics problems are:

📋 Step 1: Check Current Graphics Setup

Find Your Graphics Card

Let’s see what graphics card you have. It’s like checking what engine is in your car! 🚗

What we’re doing: Finding out which graphics card Alpine Linux sees.

# Check your graphics hardware
lspci | grep -i vga

# See more graphics details
lshw -C display

What this does: 📖 Shows you exactly which graphics card your computer has.

Warning: If you see “No devices found,” your graphics card might not be connected properly! ⚠️

🛠️ Step 2: Install Graphics Drivers

Install Basic Graphics Support

Now let’s install the drivers. Think of drivers like translators that help your computer talk to your graphics card! 🗣️

What we’re doing: Installing basic graphics drivers for Alpine Linux.

# Update package list first
apk update

# Install basic graphics drivers
apk add mesa mesa-dri-gallium

# Install Intel graphics drivers (if you have Intel)
apk add mesa-dri-intel

# Install AMD graphics drivers (if you have AMD)
apk add mesa-dri-radeon

# Install NVIDIA drivers (if you have NVIDIA)
apk add nvidia-drivers

Code explanation:

• apk update: Gets the latest package information
• mesa mesa-dri-gallium: Basic graphics support for most cards
• mesa-dri-intel: Special drivers for Intel graphics cards
• mesa-dri-radeon: Special drivers for AMD graphics cards

Expected Output:

✅ Installing mesa (1.2.3-r1)
✅ Installing mesa-dri-gallium (1.2.3-r1)
