The following are known problems and workarounds for the Lenovo Thinkpad T430s, and likely also for the related models (X230, T430, T530).
- The usual issue with laptop hard drives and disk head parking, which can be fixed with hdparm's -B option.
- At least on one T430s, using QCad with SNA would reliably crash Xorg. A workaround is using UXA instead of SNA. (FS#31617)
- The accelerometer for HDAPS is not supported.
- The system sometimes does not properly resume after being put into a suspended state. To fix, configure GRUB's use of ACPI sleep functionality by adding "acpi_sleep=nonvs" in GRUB_CMDLINE_LINUX in /etc/default/grub
- The brightness cannot always be adjusted by default. Adding
GRUB_CMDLINE_LINUX_DEFAULTand reconfiguring the grub config file fixes this.
- Fixed accurately setting the brightness levels with the Fn + brightness up/down shortcut keys. The problem comes from Intel graphics, and the solution can be found from here.
Xbindkeys or sxhkd can be used to create and modify keyboard bindings. The following example requires the package, and turns the display off when the rectangular button to the right of the microphone mute button is pressed.
