## 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 is not 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 cannot 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.

### 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
