The following instructions are for modern AMD GPU chipsets covered by the radeon driver.<br />
<br />
== Setup Xorg/udev ==<br />
<br />
# Run the <code>[[Alpine setup scripts#setup-xorg-base|setup-xorg-base]]</code> script.<br />
# Install the Xorg AMD video drivers: {{Cmd|# apk add xf86-video-ati}}<br />
# For newer devices, use: {{Cmd|# apk add xf86-video-amdgpu}}<br />
# Install the AMD firmware files if they are not already installed: {{Cmd|# apk add linux-firmware-amdgpu}}<br />
# Enable [[#Kernel Modesetting (KMS)]]. Specifically, the <code>fbcon</code> module is necessary, or leaving Xorg (via <code>Ctrl+Alt+F1</code> or quitting) will result in a black screen until the machine is power cycled. If you have already launch Xorg and don't want to experience this effect, you can <code>modprobe fbcon</code> while Xorg is running.<br />
<br />
== Kernel Modesetting (KMS) ==<br />
<br />
To enable [[KMS]] at boot:<br />
# Add the <code>radeon</code> or <code>amdgpu</code> and <code>fbcon</code> modules to {{Path|/etc/modules}}: {{Cmd|$ echo radeon >> /etc/modules<br />$ echo fbcon >> /etc/modules}} or {{Cmd|$ echo amdgpu >> /etc/modules<br />$ echo fbcon >> /etc/modules}}<br />
# Install <code>mkinitfs</code>: {{Cmd|apk add mkinitfs}}<br />
# Enable the <code>kms</code> feature in the <code>mkinitfs</code> configuration by adding it to the <var>features</var> variable, e.g., {{cat|/etc/mkinitfs/mkinitfs.conf|features{{=}}"keymap cryptsetup kms ata base ide scsi usb virtio ext4"}}<br />
# Run <code>mkinitfs</code>.<br />
# Reboot to test the configuration.<br />
<br />
== Troubleshooting ==<br />
=== Fixing MESA-LOADER errors===<br />
{{Obsolete|Alpine no longer ships with the ''linux-hardened'' kernel}}<br />
<br />
The ''linux-hardened'' kernel package places restrictions on sysfs and will prevent the MESA-LOADER from working as a normal user even if added to the video group.<br />
<br />
See https://bugs.alpinelinux.org/issues/7265<br />
<br />
Either switch to the ''linux-vanilla'' package or apply the '''grsec_sysfs_restrict=0''' kernel parameter to allow normal users to access hardware acceleration on the desktop.<br />
<br />
=== Fixing a frozen X11 when invoking startx ===<br />
<br />
You may need to set the AccelMethod to exa not glamor which is the default for the driver.<br />
<br />
{{cat|/etc/X11/xorg.conf|<br />
Section "Device"<br />
Option "AccelMethod" "exa"<br />
Identifier "Card0"<br />
Driver "radeon"<br />
