===== Post release issues and other notes for the xorg-server 1.20.7 update =====

==== Unsupported hardware ====
Version 304 of the nVidia graphics driver (''%%x11/nvidia-driver-304%%'') does not support xorg-server 1.20.  Since this is a proprietary driver, there is unfortunately not much that can be done.  If you have a need for this driver, please talk to nVidia about updating it for xorg-server 1.20.

==== Change to use DRI3 ====
Mesa has been switched to use DRI3 instead of DRI2 by default.  This should give improved performance, and is the new DRI version that upstream uses.
For users of graphics/drm-legacy-kmod or the graphics drivers in base this can cause issues though.  If %%OpenGL%% based applications no longer works when using graphics/drm-legacy-kmod, it is possible to disable DRI3 by setting the following environment variable ''%%LIBGL_DRI3_DISABLE%%'' to ''%%1%%''.
For users of bourne style (sh, bash, ksh, zsh) shells, add the following to ''%%~/.profile%%''

''%% export LIBGL_DRI3_DISABLE=1 %%''

For users of csh or tcsh, add the following to ''%%~/.cshrc%%''

''%% setenv LIBGL_DRI3_DISABLE 1 %%''

==== x11-drivers/xf86-video-ati-legacy build issues ====
The current version of ''%%x11-drivers/xf86-video-ati-legacy%%'' does not build with xorg-server 1.20.7.  A [[https://reviews.freebsd.org/D23817|patch]] has been suggested to fix the build, but help is needed to test it.

==== Input devices ====
  * make sure ''%%x11-drivers/xf86-input-libinput%%'' is installed
  * Evdev support in kernel (default in 12.1 and current)

<code>
options         EVDEV_SUPPORT           # evdev support in legacy drivers
device          evdev                   # input event device support
device          uinput                  # install /dev/uinput cdev
