With the removal of the xf86-video-* drivers, the TearFree option
|
|
is no longer functional. To work around this, upstream has added the
|
|
TearFree option to the default modesetting driver. This patch
|
|
backports this feature. Apply this patch if you are going to use Xorg
|
|
in an environment without a compositor (such as TWM, IceWM, Openbox,
|
|
or Fluxbox).

<title>Kernel Configuration</title>
|
|
|
|
<para>
|
|
The traditional Device Dependent X (DDX) drivers have been removed
|
|
from BLFS in favor of the &modesetting_drv; driver which will be
|
|
built as a part of this package. To use the &modesetting_drv; driver,
|
|
the kernel must provide a Direct Rendering Manager (DRM) driver for
|
|
your GPU.
|
|
</para>
|
|
|
|
<para>
|
|
If your GPU supports 3D acceleration and <xref linkend='mesa'/>
|
|
provides a Gallium3D driver for utilizing its 3D capability, you
|
|
should have already enabled the necessary kernel configuration options
|
|
in <xref linkend='mesa-kernel'/>. Otherwise, you need to find the
|
|
kernel configuration option of the DRM driver for the GPU and enable
|
|
it. Notably, the virtual GPUs provided by some virtual machine
|
|
managers:

|
|
href="xorg-server-kernel.xml"/>
|
|
|
|
<para>
|
|
If the kernel does not provide a DRM driver for your GPU, on most x86
|
|
systems the <quote>simple frame buffer</quote> DRM driver running on
|
|
VESA or UEFI frame buffer can be used as a fallback. Enable the
|
|
following options in the kernel configurations if you don't have a
|
|
dedicated DRM driver for the GPU, or you want to keep the simple
|
|
frame buffer driver as a fallback in case the dedicated driver fails:
|
|
</para>

|
|
href="xorg-server-simpledrm-kernel.xml"/>
|
|
|
|
<para>
|
|
To allow the kernel to print debug messages at an early boot stage,
|
|
<option>CONFIG_DRM</option> and <option>CONFIG_DRM_SIMPLEDRM</option>
|
|
should not be built as kernel modules unless an initramfs will be
|
|
used.
|
|
</para>
|
|
|
|
<para>
|
|
If you want to use the simple frame buffer driver on a system booted
|
|
via BIOS (instead of UEFI), add the following line before the first
|
|
<literal>menuentry</literal> block in the
|
|
<filename>/boot/grub/grub.cfg</filename> file to initialize the VESA
|
|
frame buffer:

You may replace <literal>1024</literal>, <literal>768</literal>, and

suitable for your monitor.

</para>
|
|
|
|
<para>
|
|
If all of these DRM drivers do not work for you and you need to use
|
|
a DDX driver with a non-DRM kernel GPU driver (usually named
|
|
<option>CONFIG_FB_*</option> in the kernel configuration, or existing
|
|
as out-tree kernel modules), or you need an device specific
|
|
functionality requiring a DDX driver, consult
|
|
<ulink url="&BLFS113;">a prior version of BLFS</ulink>, or
|
|
<ulink url="&BLFS76;">an even prior version</ulink> for more DDX
|
|
drivers.
