Hello Guys,

 I own a Dell e6420 ,  and i had installed debian buster (mate).But the brightness and wifi drivers and i assume the hdmi drivers were not installed. How can i know that all the drivers for my device is installed.

My daily driver is Debian 9 amd64 Xfce on a 2.5" SSD that I move between computers as needed. It was primarily in a Dell Inspiron E1505 for many years, but I recently upgraded to a Dell Latitude E6520.

The Inspiron had Intel graphics. I presume the Debian Installer installed the Intel graphics driver. Graphics worked, including brightness.

The Latitude has Intel graphics and an NVIDIA card ("Optimus"). I disabled Optimus in the BIOS. Graphics works, including brightness. But exploring with lspci(8), dmesg(1), /proc/modules, etc., I cannot tell if Debian is using Intel or NVIDIA (?).

I recall the Inspiron came with a Broadcom Wi-Fi adapter. I changed it out for an Intel adapter. It needed the following driver package:


The Latitude came with an Intel Wi-Fi adapter. It appears to be using the above driver, and it works:

STFW I found the following Dell web page. Given the age of our Latitude computers (ca. 2012), it may not be of much use:
