New laptop, new arch install. With a few issues.
I had a lot of trouble setting up the clickpad, especially when it comes to click+drag. I'm using i3 as my window manager and resizing an application in floating mode requires
right click + drag. To get it working:
- Install synaptics drivers:
sudo pacman -S xf86-input-synaptics
- Add the following file in
/etc/X11/xorg.conf.d/50-synaptics.conf. The base comes from
# Example xorg.conf.d snippet that assigns the touchpad driver # to all touchpads. See xorg.conf.d(5) for more information on # InputClass. # DO NOT EDIT THIS FILE, your distribution will likely overwrite # it when updating. Copy (and rename) this file into # /etc/X11/xorg.conf.d first. # Additional options may be added in the form of # Option "OptionName" "value" # Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" Option "TapButton1" "1" Option "TapButton2" "2" Option "TapButton3" "3" # This option is recommend on all Linux systems using evdev, but cannot be # enabled by default. See the following link for details: # http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html MatchDevicePath "/dev/input/event*" EndSection Section "InputClass" Identifier "touchpad ignore duplicates" MatchIsTouchpad "on" MatchOS "Linux" MatchDevicePath "/dev/input/mouse*" Option "Ignore" "on" EndSection # This option enables the bottom right corner to be a right button on clickpads # and the right and middle top areas to be right / middle buttons on clickpads # with a top button area. # This option is only interpreted by clickpads. Section "InputClass" Identifier "Default clickpad buttons" MatchDriver "synaptics" ####### !!!!!!! ######## # The following line is the important one. It defines # the areas for the right and middle buttons Option "SoftButtonAreas" "58% 0 0 15% 42% 58% 0 15%" EndSection
This works, but I couldn't get secondary soft buttons to work reliably, so they were removed.
More doc on the arch wiki.
By default, the keys to adjust brightness don't work. I added the functionality within the i3 config and with
bindsym XF86BrightnessDown exec xbacklight -dec 10 bindsym XF86BrightnessUp exec xbacklight -inc 10
To find the correct key name:
xorg-xev), and then press the keys, there is a line with
keysym 0x1008ff02 XF86MonBrightnessUp.
I pressed the key to disable the wifi, which worked, but I couldn't turn it on again :( The solution is to install (while wifi is still up)
rfkill and then:
rfkill unblock all. This is also how to be in "airplane mode" since this will shut down all wifi and bluetooth interfaces.
Input methods (bépo and chinese)
First, setup xorg to use two keyboard layouts: the standard us one (the default one from the laptop), and a french bépo layout. This is done in the file
/etc/X11/xorg.conf.d/10-keyboard.conf with the following content:
Section "InputClass" Identifier "system-keyboard" MatchIsKeyboard "on" Option "XkbLayout" "us,fr" Option "XkbVariant" ",bepo" Option "XkbOptions" "grp:shift_caps_toggle" EndSection
This will setup the two layout, and pressing
Shift+CapsLock will switch between the two.
Then, for chinese: install ibus
sudo pacman -S ibus ibus-libpinyin. Configure (and start it) with
ibus-setup. Don't forget to tick the option "Use system keyboard layout". Since in bépo layout, Shift+Space produces an unbreakable space, one need to add two modifiers to cycle through the input methods:
Finally, add the following to the file
export GTK_IM_MODULE=ibus export QS_IM_MODULE=ibus export XMODIFIERS@im=ibus ibus-daemon -dr
Sound and mic
The key to mute the audio works, but not the volume control. So install from aur
pulseaudio-ctl and then in the i3 config:
bindsym XF86AudioLowerVolume exec pulseaudio-ctl down # 5% bindsym XF86AudioRaiseVolume exec pulseaudio-ctl up bindsym XF86AudioMicMute exec pulseaudio-ctl mute-input #toggle
works out of the box. Use guvcview to try it (cool nice little program btw).
Enable and power up the card (sometimes it's down):
systemctl enable bluetooth.service && hciconfig hci0 up. To keep the device active after a reboot: add the following line in
# Set bluetooth power up ACTION=="add", KERNEL=="hci0", RUN+="/usr/bin/hciconfig hci0 up"
All info are on the arch wiki.
A few more custom things went in my i3 config. Overall, it was a-okay to put arch on this T440, the major pain being the clickpad. The nice thing here is I have very good control over practically everything here, and it's fairly easy to extend or customize according to my needs.
