Hardware Specific config

BIOS Updates

• Get latest BIOS update from Lenovo as bootable CD ISO file.
• Convert the ISO to something that you can boot from USB

sudo portmaster -i sysutils/geteltorito
geteltorito -o usb-bios-update.img n23ur13w.is

• Write the image to your USB device

sudo dd if=usb-bios-update.img of=/dev/daX bs=10M

• plug USB in X1, (re)boot
• Press enter, then F12 to choose temporary startup device
• Choose your USB device (USB HDD)
• Follow instructions from BIOS update utility

WiFi

• in /etc/rc.conf

# Wireless
wlans_iwm0="wlan0"
background_dhclient="YES"
ifconfig_wlan0="WPA DHCP country NL"

GPU

DRM Next Kernel Module

• Install the port

portmaster -i graphics/drm-next-kmod

• in /etc/rc.conf

# drm-next-kmod port
kld_list="/boot/modules/i915kms.ko"

• add your main user to video group

pw usermod ${USERNAME} -G video

• reboot

shutdown -r now

Xorg

• /etc/X11/xorg.conf

Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
  Option      "TearFree" "true"
EndSection

Note: These days all the useful options are enabled by default so no need to add too many extra parameters.

Thinkpad drivers

Used for LCD control, suspend, etc...

• in /boot/loader.conf

# Thinkpad stuff
acpi_video_load="YES"
acpi_ibm_load="YES"

Suspend

Suspend to RAM

• You need at least BIOS 1.30
• In BIOS change sleep state mode to Linux
• when you want to suspend to RAM:

sudo zzz

Note: I see the disk not super happy when resuming, with system hanging for a couple secs and lots of:

nvme0: aborting outstanding i/o
nvme0: WRITE sqid:7 cid:67 nsid:1 lba:9792488 len:64
nvme0: ABORTED - BY REQUEST (00/07) sqid:7 cid:67 cdw0:0

Not sure if this should be a concern...

Another Note: See optional config bits below for sleeping when closing lid.

Optional

• Don't want some options, /etc/make.conf

OPTIONS_SET+=SNDIO      # BSD specific sound system
 
OPTIONS_UNSET+=DOCS     # I only install specific ones
OPTIONS_UNSET+=EXAMPLES # Same
OPTIONS_UNSET+=IPV6     # IPV6 free laptop already saved the day twice

• Keyboard rate

xset rate r rate 250 34
kbdcontrol -r fast

• in /etc/sysctl.conf

# No BEEPS!
hw.syscons.bell=0
kern.vt.enable_bell=0

# Suspend to RAM when closing lid (for laptop with a working S3)
hw.acpi.lid_switch_state=S3

• If you don't like the touchpad and only use the emblematic Thinkpad pointing stick, you can disable the touchpad entirely in the BIOS (hurray!)
• in ~/.login.conf

me:\
        :charset=UTF-8:\
        :lang=en_GB.UTF-8:\
        :setenv=LC_COLLATE=C:

• in /etc/rc.conf

dbus_enable="YES"       # Enable DBUS
dumpdev="NO"            # Disable crash dumps
