Why Gentoo
I'm more of a pragmatic user of Gentoo. As an open source software developer digging into many projects, I'm taking advantage of portage, overlays, ebuilds and user patches. Gentoo serves the purpose of quickly turning my wishes into an installed package I can use for further testing or daily use.

Keyboard
US and Czech qwerty keyboard layouts, toggled with Alt+Shift, with AltGr+Menu as Compose/Multi key.

setxkbmap "us,cz(qwerty)" -option grp:alt_shift_toggle,compose:menu-altgr

Trackpoint

Portage: User patches
pre_src_prepare { if type epatch_user &> /dev/null ; then epatch_user fi }
 * 1) cat /etc/portage/bashrc

I recently switched from  to   to patch the source before running eautoreconf.

Debugging
FEATURES="splitdebug installsources"

Fedora rawhide on LXC
NAME=rawhide RELEASE=rawhide VGNAME=vg

euse -E lua caps -p app-arch/rpm emerge -v1 rpm

lxc-create -n $NAME -t fedora -B lvm --vgname $VGNAME -- -R $RELEASE

Notes:


 * With new LXC builds, LVM won't work.
 * LXC container's systemd breaks host's ttys

Systemd
From udev to systemd:

emerge --unmerge udev emerge -v systemd

What you need to have a dual boot Gentoo with systemd and OpenRC:

app-emulation/libvirt >= 1.2.3 sys-fs/lvm2 >= ???


 * Configure PAM

Network printing
Install the necessary packages:

euse -E zeroconf emerge -av cups nss-mdns system-config-printer-gnome

Make sure nss-mdns is configured:

hosts:      files mdns_minimal dns mdns
 * 1) grep hosts /etc/nsswitch.conf

Start cups and avahi-daemon.

Find and configure the printer:

system-config-printer

Get rid of window tearing
compton -c --vsync opengl --backend glx --vsync opengl-swc

Screen lock using systemd
/etc/systemd/system/slock.service:

[Unit] Description=Lock X session using slock Before=sleep.target

[Service] User=pavlix Environment=DISPLAY=:0 Type=simple ExecStart=/usr/bin/slock

[Install] WantedBy=sleep.target WantedBy=lock.target

A multi-user variant can be prepared with xautolock.
