+# These configurations are required to correct issues with AMD graphics cards when
+# they are run without firmware (as is the case in Trisquel). If you were
+# to install the nonfree firmware, comment out the first block and uncomment
+# the second, to revert to default settings.
+#
+# You may also need to check/edit /etc/modprobe.d/blacklist-amdgpu.conf

+#  * Cards using the /drm/radeon kernel module:
+#    - Models released between ~2000 and ~2013
+#    - Product names: Radeon 7000-9000, X700-X1000, HD2000-HD7000, and Radeon 200
+#    - Use the "radeon" kernel module. This module works in Trisquel 11 or newer even
+#      without nonfree firmware blobs, although those are required for 3D/2D acceleration.
+#    - These cards don't initialize correctly if the radeon kernel module were to be disabled,
+#      unless the kernel parameter 'nomodeset' is used to disable modesetting. In that case,
+#      the non-accelerated vesa driver is used. The radeon module is enabled in Trisquel >= 11
+#
+#  * Cards using the /drm/amdgpu kernel module:
+#    - Models released starting 2015
+#    - Product names: Radeon 200-600, Radeon RX Vega, Radeon VII, Radeon RX 5000 or newer
+#    - Use the "amdgpu" kernel module. This module does not work without nonfree firmware
+#      so it is disabled in Trisquel at /etc/modprobe.d/blacklist-amdgpu.conf
+#    - Those cards seem to work correctly without the amdgpu module, and they revert to
+#      using the vesa driver without the need to use kernel parameters.
