Lenovo ThinkPad T430s
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
underGRUB_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
