openSUSE Leap 15.0 - Configuration

This guide shows how to configure my minimal installation of openSUSE Leap 15.0.

Manage users

$ zypper install --no-recommends sudo

Add a new user and continue with the following sections using this new user.

Add user

Create user <user>:

$ useradd -U -u <uid> -m -k /dev/null <user>
$ passwd <user>

Configure privileges for <user> in /etc/sudoers using visudo:

$ visudo

then add/uncomment Defaults targetpw and add permissions for <user>:

/etc/sudoers

Defaults targetpw
...
<user> ALL=(ALL) ALL

Manage packages

Following the list of packages, install the additional packages:

$ sudo zypper install --no-recommends <package₁> ... <package_n>

Network manager

NetworkManager

$ sudo zypper install --no-recommends NetworkManager yast2-network

Execute yast and under "System" select "Network Settings". In the "Global Options" tab set "NetworkManager Service" as Network Setup Method.

Firewall

firewalld

$ sudo zypper install --no-recommends firewalld
$ sudo systemctl unmask firewalld.service
$ sudo systemctl enable --now firewalld.service

Wi-Fi

Broadcom 4331 (MacBook Pro 9.2)

Install either the wl-driver (option 1) or firmware for b43 driver (option 2).

Option 1 (Recommended)

Install broadcom-wl wireless driver from Packman:

$ sudo zypper ar -f http://packman.inode.at/suse/openSUSE_Leap_15.0/ Packman
$ sudo zypper refresh
$ sudo zypper install broadcom-wl broadcom-wl-kmp-default

Option 2

Install firmware for b43 wireless driver:

$ sudo zypper install --no-recommends b43-fwcutter
$ sudo install_bcm43xx_firmware

NTP

chrony

$ sudo zypper install --no-recommends chrony

systemd-timesyncd.service is in conflict with chronyd.service, so disable it first:

$ sudo systemctl disable systemd-timesyncd.service

and then enable chronyd.service:

$ sudo systemctl enable chronyd.service

Enable NetworkManager's dispatcher to inform chrony when the network status has changed:

$ sudo systemctl enable NetworkManager-dispatcher.service

Power management

TLP

$ sudo zypper install --no-recommends ethtool smartmontools tlp tlp-rdw

Enable services required by tlp:

$ sudo systemctl enable tlp.service
$ sudo systemctl enable tlp-sleep.service

Configure TLP via /etc/default/tlp:

Exclude smartphones from autosuspend (i.e. enable charging):
```
/etc/default/tlp
```
```
USB_BLACKLIST_PHONE=1
```

Use systemd-rfkill.service and systemd-rfkill.socket to restore state of radio devices:

/etc/default/tlp

RESTORE_DEVICE_STATE_ON_STARTUP=0
#DEVICES_TO_DISABLE_ON_*=...
#DEVICES_TO_ENABLE_ON_*=...

Power off, reboot, suspend, hibernate

Configure sudo to allow user <user> to execute the necessary systemctl system commands as root without asking for the password:

$ sudo visudo -f /etc/sudoers.d/usercmds

and add the following lines:

/etc/sudoers.d/usercmds

## systemctl system commands
<user> <hostname>=NOPASSWD:/usr/bin/systemctl poweroff,/usr/bin/systemctl reboot,/usr/bin/systemctl suspend,/usr/bin/systemctl hibernate

where <hostname> is the machine's hostname.

Keyboard and touchpad configuration

Tap for touchpad

Add Option "Tapping" "On" to the touchpad section in file /etc/X11/xorg.conf.d/40-libinput.conf:

/etc/X11/xorg.conf.d/40-libinput.conf

Section "InputClass"
	Identifier "libinput touchpad catchall"
	MatchIsTouchpad "on"
	MatchDevicePath "/dev/input/event*"
	Driver "libinput"
	Option "Tapping" "On"
EndSection

If the file does not exist, copy 40-libinput.conf from /usr/share/X11/xorg.conf.d/.

Function keys (MacBook Pro 9.2)

The behaviour of fn+F<num> is configured by the fnmode option of the hid_apple kernel module via the /etc/modprobe.d/hid_apple.conf file.

To disable the fn key, add the following line:

/etc/modprobe.d/hid_apple.conf

options hid_apple fnmode=0

To get F<num> by pressing fn+F<num>, add the following line:
```
/etc/modprobe.d/hid_apple.conf
```
```
options hid_apple fnmode=1
```

To get F<num> by pressing F<num>, add the following line:

/etc/modprobe.d/hid_apple.conf

options hid_apple fnmode=2

Optional - X keyboard configuration (MacBook Pro 9.2)

Optionally, configure the keyboard for X:

$ sudo localectl --no-convert set-x11-keymap <layout> apple_laptop mac

where <layout> is one of the available layouts from
