Video acceleration with Modesetting on 016.01

Details

You are reading version 017 of this page. The current version can be found here.

GoboLinux 016.01 ships with the xf86-video-modesetting driver overriding the deprecated xf86-video-intel driver. Modesetting is noticeably more stable, but it won’t offer acceleration for 2D operations by default.

You will have to recompile the following packages to achieve Gallium-based 2D acceleration on 016.01 systems:

  1. Compile libdrm
  2. Compile libva
  3. Compile intel-vaapi-driver
  4. Compile mesa
  5. Compile xorg-server 1.18.4

Furthermore, you will need to modify two Xorg settings files:

  1. Edit /System/Index/share/X11/xorg.conf.d/20-intel.conf and add an "AccelMethod" entry to the "Device" section:
Section "Device"
  Identifier "Intel Graphics"
  Driver     "modesetting"
  Option     "AccelMethod" "glamor"
EndSection
  1. Edit /System/Index/share/X11/xorg.conf.d/glamor.conf so it reads:
Section "Module"
    Load  "dri2"
    Load  "dri3"
    Load  "glamoregl"
EndSection

Now you should be able to get 2D acceleration the next time you launch the X server.
