Known issues

The following are known problems and workarounds for the Lenovo Thinkpad T430s, and likely also for the related models (X230, T430, T530).

Open issues

  • 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 isn't supported.

Has Workaround

  • 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 can't always be adjusted by default. Adding acpi_osi\='!Windows 2012' to /etc/default/grub under GRUB_CMDLINE_LINUX_DEFAULT and reconfiguring the grub config file fixes this.

Fixed

  • 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[broken link: invalid section].

Laptop Settings

Xbindkeys or sxhkd can be used to create and modify keyboard bindings. The following example requires the xorg-xset package, and turns the display off when the rectangular button to the right of the microphone mute button is pressed. 

~/.xinbkeysrc
# Close display
"xset dpms force off"
    m:0x0 + c:156
    XF86Launch1
