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.
USB 2.0 not working or giving kernel traces
Not sure if this was solved by using acpi_backlight=vendor or by blacklisting these modules I do not use:
/etc/modprobe.d/modprobe.conf
blacklist joydev blacklist pcspkr blacklist iTCO_vendor_support blacklist iTCO_wdt blacklist thinkpad_acpi # it not used by this model and gives warnings about unknown events to the logfiles when loaded.
