## Installation and configuration

### CPU & Graphics

Works fine after installation. However, some graphical issues may arise with LightDM when locking the session or resuming from suspend. If so, see Intel graphics#Xorg configuration.

Touchscreen works fine in GNOME.

### LTE/3G

Works in some situations. Some providers might not connect with the default configuration.

The built-in Sierra EM7305 is operating in mbim-mode, which is the default configuration on Windows 8/10 Systems. mbim is still not well supported in Linux. Switching to QMI-Mode can solve some problems. Source

## Keyboard backlight

For instructions on Keyboard backlight toggle see Toshiba Portege Z30-A#Keyboard Backlight control.

Since changing sys values requires root, one can either write a wrapper for bash scripts for setuid, which is generally considered insecure. Here is a simple toggle switch: KbdBacklightToggle in C

### Fn-F9 Touchpad Toggle

Needs custom hwdb to work. See Extra keyboard keys. Example hwdb provided here, but you might want to choose a different keycode: HWDB Config

## Issues

### No speaker sound when resuming from suspend to RAM
