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:  kernel-genkernel-x86_64-3.13.0-sabayon *  kernel-genkernel-x86_64-4.1.0-sabayon localhost root # eselect kernel list Available kernel symlink targets:  linux-3.13.0-sabayon  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!
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!
[email protected] ~ $ su localhost root # equo remove sys-kernel/linux-sabayon-3.13.11
TEAM RED - AMD
FGLRX to Open Source (radeon or AMDGPU)
"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.
[email protected] ~ $ su localhost root # equo update localhost root # equo remove ati-drivers ati-userspace amdcccle localhost root # equo install xf86-video-ati xf86-video-amdgpu localhost root # eselect opengl set xorg-x11 localhost root # sed -i 's/nomodeset//g' /etc/default/grub localhost root # sed -i 's/nomodeset//g' /boot/grub/grub.cfg localhost root # sed -i 's/"blacklist radeon"//g' /etc/modprobe.d/blacklist.conf localhost root # rm -rf /etc/X11/xorg.conf
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/
localhost root # vi /etc/X11/xorg.conf.d/30-Devices.conf
Now we can add typical xorg.conf configurations for the devices such as tearfree. This is typically for the more savvy.
Section "Device" Identifier "Card0" Driver "amdgpu" BusID "PCI:1:0:0" Option "TearFree" "True" Option "EnablePageFlip" "True" EndSection
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.
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.

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.
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.
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
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
