Introduction to Xorg Drivers
The Xorg Drivers page contains the
instructions for building Xorg drivers that are necessary in order
for Xorg Server to take advantage of the hardware that it is
running on. At least one input and one video driver are required
for Xorg Server to start.
On machines using KMS, the modesetting driver is provided by
xorg-server and can be used
instead of the video driver for the specific hardware, but with
reduced performance. It can also be used (without hardware
acceleration) in virtual machines running under qemu.
![[Note]](../images/note.png)
Note
If you are unsure which video hardware you have, you can use
lspci from
pciutils-3.7.0 to find out which video
hardware you have and then look at the descriptions of the
packages in order to find out which driver you need.

libevdev 1.12.0
Kernel
Configuration
Enable the following options in the kernel configuration and
recompile the kernel if necessary:
Device Drivers --->
Input device support --->
<*> Generic input layer (needed for keyboard, mouse, ...) [CONFIG_INPUT]
<*> Event interface [CONFIG_INPUT_EVDEV]
[*] Miscellaneous devices ---> [CONFIG_INPUT_MISC]
<*/m> User level driver support [CONFIG_INPUT_UINPUT]
The last item is not strictly required for libevdev. If it is
compiled as a module, it is not loaded automatically. It is
needed for full test coverage.
Installation of libevdev
Install libevdev by running the
following commands:
./configure $XORG_CONFIG &&
make
The regression tests can be run as the root user with make check, in a graphical
session. You need to have enabled the CONFIG_INPUT_UINPUT setting
in the kernel for full test coverage. If it is enabled as a
module, the module is named uinput and needs to be loaded
before running the tests. Note that on some systems, the tests
may cause a hard lockup and require a reboot. On laptops, the
system will go into Sleep and need to be woken up to finish the
test suites.
Now, as the root user:

libinput-1.19.3
kernel
configuration for running the libinput testsuite
Although libinput works with the same kernel configuration used
by libevdev-1.12.0, its extensive testsuite
requires the presence of /dev/uinput (as well as both Valgrind-3.18.1 and libunwind).
If you wish to run the full tests, enable the following option in
the kernel configuration and recompile the kernel if necessary:
Device Drivers --->
Input device support --->
Miscellaneous Devices --->
<*/M> User level driver support [CONFIG_INPUT_UINPUT]
If you build this as a module, it needs to be inserted before the
testsuite runs.
On an Xorg system you will also need to prevent the events
generated during the testsuite from interfering with your
desktop. Copy the file test/50-litest.conf into ${XORG_PREFIX}/share/X11/xorg.conf.d and
restart X. For further information see
libinput test suite.
Installation of libinput
Install libinput by running the
following commands:
mkdir build &&
cd build &&
meson --prefix=$XORG_PREFIX \
--buildtype=release \
-Ddebug-gui=false \
-Dtests=false \
-Dlibwacom=false \
.. &&
ninja
Note
If you want to run the full tests, remove -Dtests from the
meson command
above. Please read "kernel configuration for running the
libinput testsuite" (above).
If you have enabled the full tests, you can run the main tests
as the root user by
executing: ninja
test. A very large number of tests will be run,
about 20 fail (at least on an Xorg system).
Now, as the root user:
ninja install
If you have passed -Ddocumentation=true to meson, you can install the
generated documentation by running the following commands as the
root user:
install -v -dm755 /usr/share/doc/libinput-1.19.3/html &&
cp -rv Documentation/* /usr/share/doc/libinput-1.19.3/html
Command
Explanations
--buildtype=release:
Specify a buildtype suitable for stable releases of the package,
as the default may produce unoptimized binaries.
-Ddebug-gui=false: This
switch disables creation of a visual debug helper for libinput.
Remove if you want it, and you have GTK+-3.24.31 installed.
-Dtests=false: This
switch disables compilation of the main tests. Even with the
tests defined as false, you can still run the first four minor
tests, as a regular user, but one will be skipped if PyParsing
is not installed.
-Dlibwacom=false: Remove
this option if you have libwacom-2.1.0 installed, or if you are
installing GNOME.
-Ddocumentation=true: This switch
enables generation of the documentation. Add it if you want to
generate the documentation. You must have Doxygen-1.9.3
and Graphviz-2.50.0 installed.

AMDGPU Driver-21.0.0
Introduction to Xorg AMDGPU Driver
The Xorg AMDGPU Driver package
contains the X.Org Video Driver for newer AMD Radeon video cards
and newer AMD-CPUs with integrated graphics (APUs). This includes
video cards starting with Volcanic Islands. It can also be used
for Southern and Sea Islands if the experimental support was
enabled in the kernel.
This package is known to build and work properly using an
LFS-11.1 platform.
Package Information
Xorg AMDGPU Driver Dependencies
Required
Xorg-Server-21.1.3 (must be built with

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/xorg-amdgpu-driver
Kernel Configuration
Enable the following options in the kernel configuration and
recompile the kernel if necessary:
Device Drivers --->
Graphics support --->
<*> Direct Rendering Manager (XFree86 ... support) ---> [CONFIG_DRM]
<*/M> AMD GPU [CONFIG_DRM_AMDGPU]
< /*> Enable amdgpu support for SI parts [CONFIG_DRM_AMDGPU_SI]
< /*> Enable amdgpu support for CIK parts [CONFIG_DRM_AMDGPU_CIK]
The last two options enable experimental support for Southern and
Sea Islands AMD GPUs so they can be used with this driver. Note
that the support is marked experimental and disabled by default.
Xorg ATI Driver-19.1.0 should be
used for those GPUs.
Kernel Configuration for
additional firmware
If you need to add firmware, install the file(s) and then point
to them in the kernel configuration and recompile the kernel if
necessary. To find out which firmware you need, consult the
Decoder ring for engineering vs marketing names. Download any
firmware for your card which is named like: <ENGINEERING_NAME>_rlc.bin
CONFIG_EXTRA_FIRMWARE="amdgpu/topaz_ce.bin amdgpu/topaz_k_smc.bin amdgpu/topaz_mc.bin
amdgpu/topaz_me.bin amdgpu/topaz_mec2.bin amdgpu/topaz_mec.bin

amdgpu/topaz_sdma.bin amdgpu/topaz_smc.bin rtl_nic/rtl8168e-3.fw"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
Note
CONFIG_EXTRA_FIRMWARE should all be on one line. It is shown
above as multiple lines for presentation only.
![[Tip]](../images/tip.png)
Tip
You can check dmesg output after boot to
see which firmware is missing.
Alternatively, if you change CONFIG_DRM_AMDGPU to '=m' in your
linux kernel .config the firmware can be loaded automatically
from /lib/firmware/amdgpu/ when it installs the module. This
offers a tiny space saving, but also means that the screen will
be blank for a longer time before the framebuffer appears.
Distros take this approach because it is not practical to specify
every possible firmware and the kernel would be excessively big.

Working
around problems with the Intel driver
The SandyBridge New Acceleration (SNA) code is intended to

large body of code and may cause problems. However, the version
of the code in the version control system listed above has been
tested successfully with both SNA and UXA capabilities.
To work around this problem, as well as enabling support for UXA,
it is necessary to force UXA to be used by creating a
configuration file. If this problem applies to you, create the
following file as the root user
and modify it as needed:

libvdpau-1.4
Introduction to libvdpau
The libvdpau package contains a
library which implements the VDPAU library.
VDPAU (Video Decode and Presentation API for Unix) is an open
source library (libvdpau) and API originally designed by Nvidia
for its GeForce 8 series and later GPU hardware targeted at the X
Window System. This VDPAU API allows video programs to offload
portions of the video decoding process and video post-processing
to the GPU video-hardware.
Currently, the portions capable of being offloaded by VDPAU onto
the GPU are motion compensation (mo comp), inverse discrete
cosine transform (iDCT), VLD (variable-length decoding) and
deblocking for MPEG-1, MPEG-2, MPEG-4 ASP (MPEG-4 Part 2),
H.264/MPEG-4 AVC and VC-1, WMV3/WMV9 encoded videos. Which
specific codecs of these that can be offloaded to the GPU depends
on the version of the GPU hardware; specifically, to also decode
MPEG-4 ASP (MPEG-4 Part 2), Xvid/OpenDivX (DivX 4), and DivX 5
formats, a GeForce 200M (2xxM) Series (the eleventh generation of
Nvidia's GeForce graphics processing units) or newer GPU hardware
is required.
This package is known to build and work properly using an
LFS-11.1 platform.
