Touchpad not working after wake up from sleep If you are using gnome-shell, you may need to tell the settings app not to overwrite our changes: Option "ClickFinger3" "0" # Three finger click disabled Option "ClickFinger2" "3" # Right click two fingers Option "ClickFinger1" "1" # Left click one finger # Turn off the blasted corners as buttons
# Enable two finger scrolling vertically, disable horizontally The following settings can help significantly: The behavior of the trackpad by default can be contrary to your expectations, particularly if you are coming from an OS X style trackpad. ~/.xbindkeysrc # Emit a right click on Alt + trackpad click Using xbindkeys Xbindkeys and xdotool, right button clicks can be mapped to some other event. Make sure xf86-input-synaptics is not installed - the trackpad will still register button one mouse clicks. One alternative is to abandon the trackpad completely and use the trackpoint. This is due to the trackpad operating in buggy PS/2 mode. There are significant issues with the trackpad locking up on click. Keeping only xf86-input-libinput got everything working. When both xf86-input-synaptics and xf86-input-libinput are installed, the trackpoint (red thingy) uses libinput by default, so it does not cooperate with the trackpad (which by default is driven by synaptics), and as a result you cannot scroll with middle button + trackpoint. Warning: the above did the opposite for me.

To enable Trackpad support you need to install xf86-input-synaptics. To get the backtick/tilde back to a normal location, add the following definition for the Escape button: (Discuss in Talk:Lenovo ThinkPad X1 Carbon (Gen 2)) Backtick (`) and Tilde (~)

Reason: This is not the intended usage of XKB, these changes will be lost on every update of xkeyboard-config package which owns the files. Make sure xmodmap loads your new keymap on login: Install xorg-xmodmap and generate a custom key map: To get the tilde key back to a sane location on the keyboard you can use xmodmap Xmodmap to remap Shift-Esc to '~'. The difference is largely user preference. If you wish to remap keys to get back to a sane keyboard layout, you can use either xmodmap or xkb. On kernel 3.14 and lower the adaptive panel at the top of the keyboard is locked to function mode.įrom kernel 3.15, Home mode is also available which allows access to screen brightness and other controls.

If you build your own kernels, make sure to either enable TPM (Trusted Platform Module) drivers or disable the Security Chip in the BIOS. If the function keys fail to wake after suspend, ensure you have a kernel version >=3.15.

Look here for Lenovo's bios versions:Ī guide how to make a bootable BIOS key drive can be found here:Īnd some fairly old help from Lenovo here: This can be solved by flashing the bios to a version >=1.13. Wake from suspend can be buggy with earlier versions of the bios, see: To take advantage of this, see (Suspend On Low Battery Laptop#Hibernate on low battery level) Udev does not not notify whenever battery discharges by 1%, but it does notify at 80%, 20%, 5%, 4% and 0%. The kernel module tp_smapi is not currently supported.
The kernel module thinkpad_acpi picks up most of the sensors. Most of the hardware is based on the Intel Lynx Point reference design.
