I am not using a multilib profile on gentoo (I use amd64 only everywhere), so when the time came to install steam I had to get a little creative. Overall I believe this is the perfect way to install and use steam as it self contains it cleanly while not limiting the functionalities. In particular sound works, as does the hardware acceleration in games. I tried to achieve that with containers but didn’t quite made it work as well as this chroot setup.
Note that there is no way to provide a “most recent stage 3” installation link. You will have to browse http://distfiles.gentoo.org/releases/amd64/autobuilds/current-stage3-amd64/ and adjust the download url manually bellow :
mkdir /usr/local/steam cd /usr/local/steam wget http://distfiles.gentoo.org/releases/amd64/autobuilds/current-stage3-amd64/stage3-amd64-20190122T214501Z.tar.xz tar -xvpf stage3* rm stage3* cp -L /etc/resolv.conf etc mkdir usr/portage mkdir -p srv/gentoo-distfiles mount -R /dev dev mount -R /sys sys mount -t proc proc proc mount -R /usr/portage usr/portage mount -R /usr/src usr/src mount -R /srv/gentoo-distfiles/ srv/gentoo-distfiles/ mount -R /run run cp /etc/portage/make.conf etc/portage/ sed -e '/LLVM_TARGETS/d' -e '/getbinpkg/d' -i etc/portage/make.conf rm -rf etc/portage/package.use cp /etc/portage/package.use etc/portage/ cp /etc/portage/package.accept_keywords etc/portage/ chroot . env-update && source /etc/profile wget -P /etc/portage/repos.conf/ https://raw.githubusercontent.com/anyc/steam-overlay/master/steam-overlay.conf emaint sync --repo steam-overlay emerge dev-vcs/git -q emerge --ask games-util/steam-launcher useradd -m -G audio,video steam
Note that we use
su and not
su - since we need to preserve the environment. If you don’t you won’t get any sound in game. The pulseaudio socket is shared through the mount of
/run inside the chroot :
su cd /usr/local/steam mount -R /dev dev mount -R /sys sys mount -t proc proc proc mount -R /usr/portage usr/portage mount -R /usr/src usr/src mount -R /run run chroot . env-update && source /etc/profile su steam steam
