Jumping cursor on touchpad release
A jumping cursor when releasing the finger makes it impossible to hit small objects. Solved with synclient(1) FingerHigh/Low:
$ synclient FingerHigh=40 $ synclient FingerLow=40
Troubleshooting
Brightness control
Brightness can only be switched between darkest and brightest values using OS method.
The fix is to make the thinkpad-acpi kernel module control it: append thinkpad-acpi.brightness_enable=1 acpi.brightness_switch_enabled=0 to the kernel line in the bootloader.
