## Installation and configuration

### CPU & Graphics

Works fine after installation, the video have some issues with lightdm locker when locking the session or after resume, if that's the case the configuration recommended for Intel works [Intel Arch](/index.php/Intel_graphics#Configuration "Intel graphics")
Touchscreen works fine tested in gnome.

### Touchpad

It Works without any modification including gestures.

### Bluetooth

Works

### Wifi

Works

### 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](http://www.0xf8.org/2015/07/dell-wireless-5809e-support-in-linux-a-followup/#more-1258)

### Smart Card Reader

Works fine, it is a mini SD card reader not a regular SD Card.

### Display Backlight Control

It works out of the box, even after resume, no additional package has been installed

### Keyboard Backlight control

Works

For instructions on Keyboard backlight toggle see [Toshiba Portege Z30-A#Installation and configuration](/index.php/Toshiba_Portege_Z30-A#Installation_and_configuration "Toshiba Portege Z30-A").

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](https://github.com/Exel232/Configurations/raw/master/Toshiba/kbdback.c)

### Fn-F9 Touchpad Toggle

Needs custom hwdb to work. See [Extra keyboard keys](/index.php/Extra_keyboard_keys "Extra keyboard keys"). Example hwdb provided here, but you might want to choose a different keycode: [HWDB Config](https://github.com/Exel232/Configurations/raw/master/Toshiba/60-toshiba-input.hwdb)
