DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owners would know how get the best out of that hardware. The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware. If you need help to get Debian running on your hardware, please have a look at our user support channels where you may find specific channels (mailing list, IRC channel) dedicated to certain types of hardware. |

Configuration
Webcam
Works out of the box but with a very strong red tint. To correct, install guvcview and tick "White Balance Temperature, Auto".
WiFi
Wireless did not work out-of-the box, but required installation of the non-free Debian package firmware-iwlwifi.
Modem (GSM)
Integrated optional Sierra EM7345 4G LTE M.2 Module
Doesn't work directly, dmesg :
cdc_ncm 2-4:1.9: MAC-Address: ff:ff:ff:ff:ff:ff
The solution is to enable the prefer_mbim option of cdc_ncm module. /etc/modprobe.d/local_t440s.conf :
option cdc_ncm prefer_mbim=Y
