=== Kernel Source Patchset Version Note===
 
Portage has numerous versions of the Linux kernel source. The most common ones used in Sabayon are gentoo-sources and sabayon-sources. gentoo-sources consists of the default Linux Kernel with the Gentoo patchset and works well for most Gentoo and Sabayon users. sabayon-sources of the default Linux Kernel with the Gentoo patchset  and the Sabayon patchset to add better but slightly more experimental support for the latest SATA or PATA , wireless and other emergent drivers.
 
  
Valid kernelname parameters include sabayon , gentoo, hardened , rsbac , ppa, mips, sh, sparc, xbox , and numerous others.

{{Console| <pre class="clear">
To Install Nvidia Accelerated drivers (closed blob) for more recent video cards, e.g. 520GT, follow these steps in order:
+
   
+
localhost root # equo update
Firstly, attempt to discover the kernel revision your sabayon install is currently using, you can achieve this by opening an instance of a command line interface or Terminal emulator and type in this instruction into the terminal:
+
</pre>}}
uname -a
+
 
   
+
== Method 1 (kernel-switcher tool) ==
You should see from the very beginning of the screen (far left of the screen, in the terminal box) your host name which will say: Linux, and the name you gave your PC, during the installation of sabayon. Next you will see the kernel version and then it's description... which should resemble something like this:
+
 
[3.2.0-sabayon #1 SMP]
+
This method should automagically install the corresponding driver updates and addons such as the zfs mod.
   
+
 
Using this information, use either Sulfur (GUI) or equo (command line) installer and search for the correct revision that suits your graphics card and kernel version that we have just discovered. This case we will want to install the Nvidia 290.xx driver that matches the kernel which is 3.2.0-sabayon #1 SMP
+
 
   
+
Lets see what is available!
Before we install, we want to make sure that there are no possible driver conflicts
+
{{Console| <pre class="clear">
   
+
localhost root # kernel-switcher list
For example: while I was learning this, the ATI fglrx (closed blob for ATI cards) driver was installed, along side nouveau(open sourced nvidia driver), plus the eselect program was pointed to the ATI driver, which did not help matters much...
+
</pre>}}
   
+
 
You can detect if they are installed or not by typing in a root terminal by typing either "su root" (without quotes) followed by your username and pass or "sudo equo" (without quotes) search ATI and repeat the process for nouveau.
+
Find a kernel you wish to use, and switch!
   
+
{{Console| <pre class="clear">
If you find either offending package, just type "equo remove ati-drivers" and/or "xf86-video-nouveau" (without quotes)
+
localhost root # kernel-switcher switch linux-sabayon-4.1.7
   
+
</pre>}}
Once you found the correct version and type of graphic drivers you will ether need to right click on the driver package in Sulfur, then select install or alternatively type in "equo install nvidia-drivers-295.20#3.2.0-sabayon" (without quotes)
+
 
   
+
== Method 2 (Manual) ==
This will download, install and compile the modules into the kernel, but you will have to setup the last two bits yourself.
+
 
   
+
This method isn't better or worse than kernel-switcher. It just allows you to know exactly whats going on, what you are doing, and what is changing. This method doesn't automagically upgrade drivers or install addons such as virtualbox addons or the zfs mod.
Follow these last two steps to complete the process:
+
{{Console| <pre class="clear">
Not doing these can cause your system to freeze, lock up and have a blank screen if not completed properly, if you choose to run a game or use your card's accelerated features!
+
localhost root # equo install sys-kernel/linux-sabayon
   
+
localhost root # equo install sys-kernel/sabayon-sources
In a root terminal type:
+
</pre>}}
eselect opengl set nvidia
+
 
 +
 
 +
Now use eselect to set the soft links(shortcuts) to the proper libraries and files.
 +
eselect allows us to keep different libraries so we can switch without damaging the system by replacing important files.
 +
 
 +
First off we need to know which is our new kernel and bzimage
 +
 
 +
{{Console| <pre class="clear">
 +
localhost root # eselect bzimage list
 +
localhost root # eselect kernel list
 +
</pre>}}
 +
 
 +
 
 +
You should get something like this...
 +
 
 +
{{Console| <pre class="clear">
 +
localhost root # eselect bzimage list
 +
Available kernel targets:
 +
  [1]  kernel-genkernel-x86_64-3.13.0-sabayon *

 +
 
 +

Now select the newer bzimage and kernel.
 +
 
 +
{{Console| <pre class="clear">

{{Note| '''SED'''
 +
In these instructions you'll notice the sed command. This may make some people leary as not everyone understands this command. "sed" stands for "stream editor". It can edit the edit file for you by substituting lines, words, strings, etc. In this case we are using it to remove a line in blacklist.conf and nomodeset command in grub config files.
 +
 
 +
If you don't feel fully comfortable about this command. Back up your file or use nano (vi etc.) to edit the file!

"Why" you ask? Besides the drivers not quickly supporting new Kernel releases, Open Source drivers are getting better all the time and AMD has announced plans to open source as much as possible. The majority of the drivers will be opensource while proprietary features will remain in a kernel agnostic binary blob. If you want to go full opensource, then the driver will hook into mesa for all rendering etc. If you want proprietary features, the same driver hooks into a binary blob. Same driver, different options. AMDGPU-PRO will basically be a full install of the opensource driver, but with binaries included. Currently AMDGPU-PRO isn't available to Gentoo in this BETA phase.
 +
 
 +
{{Console| <pre class="clear">

 +
localhost root # rm -rf /etc/X11/xorg.conf
 +
</pre>}}
 +
 
 +
Newer versions of X11 do not require an xorg.conf file. If any special settings are required or wanted you can apply an override in /etc/X11/xorg.conf.d/
 +
 
 +
{{Console| <pre class="clear">
 +
localhost root # vi /etc/X11/xorg.conf.d/30-Devices.conf
 +
</pre>}}
 +
 
 +
Now we can add typical xorg.conf configurations for the devices such as tearfree. This is typically for the more savvy.
 +
 
 +
{{Console| <pre class="clear">

 +
 
 +
== '''AMDGPU w/Display Code *EXPERIMENTAL!*''' ==
 +
 
 +
 
 +
So first you'll want to be aware you're going to be adding a couple community repositories for packages. One repository will be using -9999 packages for MESA, LIBDRM, and LLVM.
 +
You'll also want to be aware that you should still keep your current kernel in case anything goes wrong. That will allow you to continue booting into your system from the advanced options in GRUB by selecting the older kernel. This newer kernel and experimental packages will not be supported.
 +
 
 +
{{Warning| '''Not all AMD Display Code is not mainline!'''
 +
This contains incomplete code that has yet not been adopted into the mainline kernel. Results may vary and this may not be the same as the finalized versions of code.
 +
}}
 +
 
 +
 
 +
Lets get started with prep work!

{{Console| <pre class="clear">

 +
</pre>}}
 +
 
 +
 
 +
Now lets download a kernel with display code.
 +
 
 +
{{Console| <pre class="clear">
 +
localhost root # git clone -b amd-staging-drm-next --depth=1 git://people.freedesktop.org/~agd5f/linux

localhost root # rm -rf linux
 +
localhost root # ln -s linux-4.17.0-amdgpu/ linux
 +
localhost root # cd linux
 +
</pre>}}
 +
 
 +
 
 +
Now we finish configuring and building the kernel. Now's you chance to make any other config changes you want. If you use lvm add the --lvm flag to the genkernel command.
 +
You can also double check Device Drivers -> Graphics Support -> Display Engine Configuration -> AMD DC is enabled as well as Raven family if you plan on owning an APU based on Raven.
 +
 
 +
{{Console| <pre class="clear">
 +

 +
 
 +
 
 +
You can watch the git repo for updates/fixes/changes etc at https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next to decide if you want to update the kernel again. If you do this, none of the sed commands are necessary for the config as /proc/config.gz will already have the updated config changes.

== Booting live/installer disc with vesa graphics on older GPUs ==
 +
Can't seem to get the GUI on the installer disc and seem stuck at a black screen or terminal? We've got you covered. When selecting an option from the boot screen
 +
edit the boot line and include the following at the end of the line.
 +
 
 +
{{Console| <pre class="clear">modprobe.blacklist=nvidia xdriver=vesa</pre>}}
 +
 
 +
This should get you into the live session to perform an install. Afterwards, you'll need to either switch to Nouveau or a proprietary driver version that supports your card.
 +
 
 +
=='''Proprietary'''==
 +
Sabayon should already come with the latest nvidia-drivers, but if for some reason you don't have correct proprietary Nvidia drivers installed
 +
there are simple steps to follow.
 +
 
 +
=== Prepare if returning from nouveau ===
 +
Because we use the proprietary drivers by default, the opensource driver is usually already blacklisted; but if you switched to the opensource driver and are
 +
returning to the proprietary offerings, you must first blacklist the opensource driver.
 +
 
 +
{{Console| <pre class="clear">localhost root # sed -i s/'#blacklist nouveau'/'blacklist nouveau'/ /etc/modprobe.d/blacklist.conf </pre>}}
 +
 
 +
=== Available driver version ===
 +
 
 +
To get a list of all drivers for all kernels that are available:
 +
{{Console| <pre class="clear">$ equo search -qv nvidia-drivers</pre>}}
 +
 
 +
List of all drivers versions available for currently running kernel:
 +
{{Console| <pre class="clear">$ equo search -qv nvidia-drivers#$(uname -r)</pre>}}
 +
 
 +
=== Newest drivers for currently running kernel ===
 +
{{Console| <pre class="clear">localhost root # equo install --ask nvidia-driver#$(uname -r) nvidia-userspace</pre>}}
 +
Will install newest driver available for currently running kernel.
 +
 
 +
=== Older drivers for currently running kernel ===
 +
{{Note| '''Not supported or Guaranteed'''
 +
It has been noticed that depending on the old GPU or GPU drivers version, they may or may not work. This seems pretty hit and miss.
 +
Mobile GPUs and non-discrete GPUs (integrated in the motherboard) appear to be affected by this. If you're using an GPU older than
 +
Fermi or an integrated GPU, we recommend using the open source nouveau driver.
 +
}}
 +
 
 +
List Nvidia drivers for your current kernel (insturctions above), and install it along with corresponding '''nvidia-userspace''', e.g.:
 +
{{Console| <pre class="clear">localhost root # equo install --ask nvidia-drivers-340.104#$(uname -r) nvidia-drivers-340.104</pre>}}
 +
 
 +
now lets switch from opensource opengl libraries to proprietary nvidia opengl libraries
 +
 
 +
{{Console| <pre class="clear">localhost root # eselect opengl set nvidia</pre>}}
 +
 
 +
=='''Open Source - Switching to Nouveau drivers'''==
 +
If Sabayon is installed you reboot and you find you're stuck at a login terminal or just wan to switch to open source drivers, this is a simple fix.
 +
Just login with your user you created. Then we'll remove the proprietary drivers and the blacklist for nouveau using the following:
 +
 
 +
=== Unblock nouveau driver ===
 +
Because we use the proprietary drivers by default, the opensource driver is blacklisted. You must first unblock the driver from being loaded.
 +
 
 +
{{Console| <pre class="clear">localhost root # sed -i s/'blacklist nouveau'/'#blacklist nouveau'/ /etc/modprobe.d/blacklist.conf </pre>}}
 +
 
 +
You still must block or remove the proprietary driver. Now that both drivers have the ability to load, it will most likely lock up the machine
 +
on boot or cause instability. Both drivers cannot be loaded at the same time.
 +
 
 +
=== Removal of proprietary driver ===
 +
You can blacklist the nvidia drivers OR remove them entirely. Removal is the simplest method.
 +
 
 +
{{Console| <pre class="clear">localhost root # equo update; equo remove nvidia-drivers nvidia-userspace</pre>}}
 +
 
 +
Now lets make sure we're using the correct opengl libraries
 +
 
 +
{{Console| <pre class="clear">localhost root # eselect opengl set xorg-x11</pre>}}
 +
 
 +
Now reboot and you'll be using nouveau. If you ever feel like returning to proprietary drivers, you'll need to blacklist nouveau again. then
  
Make sure your user is in the video group by typing "gpasswd -a <username> video" (without quotes, replace <username> with your username e.g. gpassword -a mike video) in a terminal as root.

SUPPORTED AMD HARDWARE

FGLRX is currently deprecated. AMDGPU is the new platform. Devices not supported by AMDGPU will be supported by radeon. AMDGPU-PRO is currently only supported on .deb and .rpm distributions.

Kernel Upgrade (optional)

Repository Database Update

First things first! Update the database to make sure we have the most up to date package available! This will give us the most recent list of kernels and drivers.

[email protected] ~ $ su
localhost root # equo update

Method 1 (kernel-switcher tool)

This method should automagically install the corresponding driver updates and addons such as the zfs mod.


Lets see what is available!

localhost root # kernel-switcher list

Find a kernel you wish to use, and switch!

localhost root # kernel-switcher switch linux-sabayon-4.1.7

Method 2 (Manual)

This method isn't better or worse than kernel-switcher. It just allows you to know exactly whats going on, what you are doing, and what is changing. This method doesn't automagically upgrade drivers or install addons such as virtualbox addons or the zfs mod.

localhost root # equo install sys-kernel/linux-sabayon
localhost root # equo install sys-kernel/sabayon-sources


Now use eselect to set the soft links(shortcuts) to the proper libraries and files. eselect allows us to keep different libraries so we can switch without damaging the system by replacing important files.

First off we need to know which is our new kernel and bzimage

localhost root # eselect bzimage list
localhost root # eselect kernel list


You should get something like this...

localhost root # eselect bzimage list
Available kernel targets:
  [1]   kernel-genkernel-x86_64-3.13.0-sabayon *
  [2]   kernel-genkernel-x86_64-4.1.0-sabayon
localhost root # eselect kernel list
Available kernel symlink targets:
  [1]   linux-3.13.0-sabayon
  [2]   linux-4.1.0-sabayon *
localhost root # 


Now select the newer bzimage and kernel.

localhost root # eselect bzimage set 2
localhost root # eselect kernel set 2


Once your new kernel is installed reboot!

Clean (optional)

Once you have everything working you can remove the old kernel if you like. MAKE SURE YOU SELECT THE CORRECT KERNEL! Look using "equo search linux-sabayon" then copy and paste!

Now we can add typical xorg.conf configurations for the devices such as tearfree. This is typically for the more savvy.

AMDGPU w/Display Code *EXPERIMENTAL!*

So first you'll want to be aware you're going to be adding a couple community repositories for packages. One repository will be using -9999 packages for MESA, LIBDRM, and LLVM. You'll also want to be aware that you should still keep your current kernel in case anything goes wrong. That will allow you to continue booting into your system from the advanced options in GRUB by selecting the older kernel. This newer kernel and experimental packages will not be supported.

Not all AMD Display Code is not mainline!

This contains incomplete code that has yet not been adopted into the mainline kernel. Results may vary and this may not be the same as the finalized versions of code.


Lets get started with prep work!

localhost root # equo update; equo upgrade
localhost root # equo install enman
localhost root # enman add gaming-live
localhost root # enman add community
localhost root # equo update; equo upgrade
localhost root # echo "media-libs/mesa-9999" >> /etc/entropy/packages/package.unmask
localhost root # echo "x11-libs/libdrm-9999" >> /etc/entropy/packages/package.unmask
localhost root # echo "sys-devel/llvm-9999" >> /etc/entropy/packages/package.unmask
localhost root # equo install v86d bison make cmake automake gcc genkernel-next git dev-python/sphinx re2c dev-util/ninja sys-devel/llvm-9999 x11-libs/libdrm-9999 media-libs/mesa-9999


Now lets download a kernel with display code.

localhost root # git clone -b amd-staging-drm-next --depth=1 git://people.freedesktop.org/~agd5f/linux    
localhost root # mv linux /usr/src/linux-4.17.0-amdgpu
localhost root # cd /usr/src
localhost root # rm -rf linux
localhost root # ln -s linux-4.17.0-amdgpu/ linux
localhost root # cd linux


Now we finish configuring and building the kernel. Now's you chance to make any other config changes you want. If you use lvm add the --lvm flag to the genkernel command. You can also double check Device Drivers -> Graphics Support -> Display Engine Configuration -> AMD DC is enabled as well as Raven family if you plan on owning an APU based on Raven.

localhost root # zcat /proc/config.gz > /usr/src/config
localhost root # sed -i '5495 a CONFIG_DRM_AMD_DC=y' /usr/src/config
localhost root # sed -i '5496 a CONFIG_DRM_AMD_DC_DCN1_0=y' /usr/src/config
localhost root # genkernel --kernel-config=/usr/src/config --menuconfig --splash=sabayon --luks all
localhost root # grub2-mkconfig -o /boot/grub/grub.cfg 


You can watch the git repo for updates/fixes/changes etc at https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next to decide if you want to update the kernel again. If you do this, none of the sed commands are necessary for the config as /proc/config.gz will already have the updated config changes.

TEAM GREEN - NVIDIA

Booting live/installer disc with vesa graphics on older GPUs

Can't seem to get the GUI on the installer disc and seem stuck at a black screen or terminal? We've got you covered. When selecting an option from the boot screen edit the boot line and include the following at the end of the line.

modprobe.blacklist=nvidia xdriver=vesa

This should get you into the live session to perform an install. Afterwards, you'll need to either switch to Nouveau or a proprietary driver version that supports your card.

Proprietary

Sabayon should already come with the latest nvidia-drivers, but if for some reason you don't have correct proprietary Nvidia drivers installed there are simple steps to follow.

Prepare if returning from nouveau

Because we use the proprietary drivers by default, the opensource driver is usually already blacklisted; but if you switched to the opensource driver and are returning to the proprietary offerings, you must first blacklist the opensource driver.

localhost root # sed -i s/'#blacklist nouveau'/'blacklist nouveau'/ /etc/modprobe.d/blacklist.conf 

Available driver version

To get a list of all drivers for all kernels that are available:

$ equo search -qv nvidia-drivers

List of all drivers versions available for currently running kernel:

$ equo search -qv nvidia-drivers#$(uname -r)

Newest drivers for currently running kernel

localhost root # equo install --ask nvidia-driver#$(uname -r) nvidia-userspace

Will install newest driver available for currently running kernel.

Older drivers for currently running kernel

Not supported or Guaranteed

It has been noticed that depending on the old GPU or GPU drivers version, they may or may not work. This seems pretty hit and miss. Mobile GPUs and non-discrete GPUs (integrated in the motherboard) appear to be affected by this. If you're using an GPU older than Fermi or an integrated GPU, we recommend using the open source nouveau driver.

List Nvidia drivers for your current kernel (insturctions above), and install it along with corresponding nvidia-userspace, e.g.:

localhost root # equo install --ask nvidia-drivers-340.104#$(uname -r) nvidia-drivers-340.104

now lets switch from opensource opengl libraries to proprietary nvidia opengl libraries

localhost root # eselect opengl set nvidia

Open Source - Switching to Nouveau drivers

If Sabayon is installed you reboot and you find you're stuck at a login terminal or just wan to switch to open source drivers, this is a simple fix. Just login with your user you created. Then we'll remove the proprietary drivers and the blacklist for nouveau using the following:

Unblock nouveau driver

Because we use the proprietary drivers by default, the opensource driver is blacklisted. You must first unblock the driver from being loaded.

localhost root # sed -i s/'blacklist nouveau'/'#blacklist nouveau'/ /etc/modprobe.d/blacklist.conf 

You still must block or remove the proprietary driver. Now that both drivers have the ability to load, it will most likely lock up the machine on boot or cause instability. Both drivers cannot be loaded at the same time.

Removal of proprietary driver

You can blacklist the nvidia drivers OR remove them entirely. Removal is the simplest method.

localhost root # equo update; equo remove nvidia-drivers nvidia-userspace

Now lets make sure we're using the correct opengl libraries

localhost root # eselect opengl set xorg-x11

Now reboot and you'll be using nouveau. If you ever feel like returning to proprietary drivers, you'll need to blacklist nouveau again. then
