RAM

Opened back with slot for RAM

ThinkPad T430 supports up to 16 GB of SO-DIMM DDR3/DDR3L memory. Max frequency for some machines is 2133 MHz, but personally I got black screen without loading with 2133 MHz memory, so check in shop before buy. DDR3L is better because it is 1.35V instead of 1.5V so it uses 10 percent less battery with the same performance as DDR3. To check how much of memory the laptop has:

root #dmidecode -t memory | grep -i size
	Size: 4096 MB
	Size: No Module Installed

This shows one 4GB module is installed and a second is unpopulated but available.

To find out the frequency of installed RAM modulesː

root #dmidecode -t memory | grep 'Memory Speed'
	Configured Memory Speed: 1600 MT/s
	Configured Memory Speed: Unknown

When a second RAM module is installed, they will operate on the same frequency (the lowest one from both), but size can differ (for example 4 GB plus 8 GB).

See video about how to replace RAM.

Hard Drive

Better replace for SSD for higher speed, 2.5 inch (SATA III: 6Gb/s) or mSATA (SATA II: 3Gb/s). Good models: MX500, BX500, Samsung EVO 870[1].

Also you can replace DVD ullrabay to SSD caddy[2] - SATA III[3].

So totally you can have 3 drives inside this laptop (plus USB).

Trim

If you have SSD — sometimes you need to trim it for faster writing. Do not mount with discard option - it will be slower and can be harmful. Better trim on poweroff, on Fridays:

FILE /etc/local.d/10-run_on_shutdown.stop
#!/bin/bash

# From
# https://fitzcarraldoblog.wordpress.com/2018/01/13/running-a-shell-script-at-shutdown-only-not-at-reboot-a-comparison-between-openrc-and-systemd/
if [ `who -r | awk '{print $2}'` = "0" ] && [ "$(date +%a)" = "Fri" ]; then
    echo /etc/local.d/10-run_on_shutdown.stop: run SSD trim
    fstrim / --verbose
    sleep 5
fi

make it executable:

user $chmod +x /etc/local.d/10-run_on_shutdown.stop

/etc/local.d/etc/local.d/ can contain small programs or light scripts to be run when the local service is started or stopped. .

By default prints are hidden, to show them:

FILE /etc/conf.d/local
rc_verbose=yes

Battery

Get current battery level (useful when using i3 or Sway window managers without GUI battery indicator)[4]ː

user $cat /sys/class/power_supply/BAT0/capacity

Installation

Firmware

Wi-Fi

The Linux firmware package is needed since the Centrino Advanced-N 6205 AGN wifi adapter requires a specific firmware file.

Firmware file that is needed is the iwlwifi-6000g2a-6.ucode. It can be obtained by installing the Linux firmware package: sys-firmware/linux-firmware or sys-firmware/iwl6005-ucode.

FILE /etc/portage/make.conf
# ipw3945 needed for ThinkPad wireless firmware
ACCEPT_LICENSE="@FREE ipw3945"

After every kernel update (after make) execute

root #make modules_install

For more info see iwlwifi.

Note
When error messages saying the kernel isn't able to find the iwlwifi-6000g2a-6.ucode, check content of /lib/firmware/.

To make connection emerge wpa_supplicant:

root #emerge --ask net-wireless/wpa_supplicant

Edit config file, this is an example (see more at man 5 wpa_supplicant.conf and /usr/share/doc/wpa_supplicant-2.10-r1/wpa_supplicant.conf.bz2):

FILE /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=0

ap_scan=1

network={
	ssid="A1-13"
	psk="this is my password"
	priority=1
}

network={
	ssid="POCO X3 Pro"
	psk="and another password"
	priority=2
}

network={
	ssid="hackerspace"
	psk="yet another password"
	priority=9
}

network={
	ssid="HUAWEI-25 a-2"
	psk="password"
	priority=99
}

Connect to Wi-Fi with this command:

root #/etc/init.d/wpa_supplicant start

You can replace mini-PCI (half) WLAN module to something that do not need proprietary blobs, for example AR5BHB116.

Ethernet

root #cd /etc/init.d/

To try to use Ethernet on laptop boot (run by init system):

root #rc-update add net.enp0s25

Bluetooth

root #dmesg
bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-21e6.hcd failed with error -2

Thus a Linux firmware file BCM20702A1-0a5c-21e6.hcd is needed. See Broadcom Bluetooth for additional info.

Sound

If you plan to use Firefox for meetings - you need PulseAudio, because Firefox has the issue that when built with Alsa - your microphone will not work.

You can get or review my /etc/portage configs.

With Intel Modesetting DDX as video driver and libinput as input driver add the USE flags glamor and libinput.

Firefox video performance

Video performance is better on media-video/mpv (use --hwdec=vaapi), but from 2021 you can USE="vaapi" and enable WebRender in Firefox (if not enabled by default, see about:support) to use GPU for video and get higher FPS. Also in firefox in about:support enable gfx.webrender.all (tested on Firefox 86).

To check that it works: emerge x11-apps/igt-gpu-tools and run intel_gpu_top: it must show loading for Video when Firefox plays YouTube, not like this 0%:

So you can install popular browser extension h264ify. On YouTube make right click on video and choose Stats for nerds, see Codecs line. Also check media.ffmpeg.vaapi.enabled.

You can check video performance on this video, maybe vp9 and av1 will play smoothly for you even without hardware decoding (0% Video in intel_gpu_top).

ThinkLight

Fn-Space to enable/disable the ThinkLight, useful to see the keyboard in low light conditions.

Displays

Multiple displays

T430-three-displays-and-dock-4337.jpg

To add more displays[5], there are several methods: one additional external display, or attach two external displays but internal panel will be disabled, or to do a triple monitor setup[6] with a T430 (iGPU model) you'll need the 4337 or 4338 dock for its dual DisplayPort, external screens need to have the same setting (resolution & refresh rate) and interface type (DisplayPort, hence needing the dock). If the monitors lack a DisplayPort you can use an Active cable or adapter (passive cables & adapters won't work).

Also you can use x11-misc/synergy (Wayland support in development) or x11-misc/barrier (Wayland support in development) to unite multiple computers.

Fastboot (reduce flickering on boot)

Uncomment and add:

FILE /etc/default/grub
GRUB_CMDLINE_LINUX="i915.fastboot=1"

and regenerate grub, as usual after kernel update:

root #grub-mkconfig -o /boot/grub/grub.cfg

See more about fastboot.

Fix screen tearing

When watching some videos, some frames may be out of sync with the screen rate. Screen tearing can be fixed in multiple ways. For Xorg: Thinkpad T430 has Intel GPU, create this file:

FILE /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"    "true"
EndSection

And emerge x11-drivers/xf86-video-intel (because still not implemented in the default xf86-video-modesetting).

Reboot the system for the new configuration to take effect.

Another option against screen tearing: use Sway window manager, because underlying Wayland protocol has no screen tearing by design.

Pros of Wayland (Sway):
  1. A little bit better scrolling in Firefox, better video playing (no drop frames, even if Youtube shows 0), more FPS
  2. No need for xf86-video-intel driver
Cons of Wayland
  1. Difficult screencasting for Google Meet in Firefox, you will need to mess around with unstable PipeWire, xdg-desktop-portal-wlr, personally I got no success in January 2022 after a few hours of trying, see this defect
  2. Xorg will be installed if you compile Firefox with PGO, looks like Firefox uses Xorg virtual screen for testing
  3. Impossible to use ffmpeg for screen grabbing, but other options exists
  4. The most minor - you will need to change your screenshot software from scrot (or maim) to grim

You can check tearing on this video.

i3 bindsym for screenshot to file with a good name and to clipboard

File name will be like 2022-jan-15--12-05-59_maim.png.

bindsym $mod+Shift+s exec maim --select --hidecursor |\
    tee /tmp/$(date +%Y-%b-%d--%H-%M-%S_maim | tr A-Z a-z).png |\
    xclip -selection clipboard -t image/png

Alter brightness

Brightness value live in a file /sys/class/backlight/intel_backlight/brightness, to react current valueː

user $cat /sys/class/backlight/intel_backlight/brightness
89

To alter brightnessː

root #echo 100 > /sys/class/backlight/intel_backlight/brightness

Alternatively, install sys-power/acpilight or dev-libs/light to control brightness with the xbacklight or light tools respectively.

Keyboard layouts

This is usual, for example here we add Russian language, change by Caps:

FILE /etc/X11/xorg.conf.d/10-keyboard.conf
Section "InputClass"
    Identifier "keyboard-all"
    Driver "evdev"
    Option "XkbLayout" "us,ru"
    Option "XkbOptions" "grp:caps_toggle"
    MatchIsKeyboard "on"
EndSection

Screen recording with ffmpeg and vaapi

To h264, because GitHub supports this format (mp4), not webm (vp9), and Ivy Bridge supports hardware encoding to h264:

user $ffmpeg -vaapi_device /dev/dri/renderD128 -f x11grab -video_size 1366x768 -i :0+1200,1152 -vf 'format=nv12,hwupload' -c:v h264_vaapi o.mp4

ffmpeg records middle display, where width of the left is 1200 and height is 1920 (1920 - 768 = 1152).
