Check if the driver package for your device is installed. Rebooting will be necessary, and you may need to check configuration defaults. Mark

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

How can i know that all the drivers for my device is installed. The typo in the Subject: is a bit unfortunate, but we can work with that. The first thing you need to know is the difference between driver and firmware. A driver is a chunk of code that runs inside the kernel, often loaded on demand as a kernel module. Most drivers are included in the kernel packages that you've already installed. Some drivers have to be built from source code on your system, using headers that match your kernel. Firmware is a chunk of code that runs inside a device. It's loaded from a file on your disk, and uploaded into the device at boot time. The kernel doesn't know or care what the firmware does; the kernel only needs to know its name. When it comes to firmware, you can usually run "dmesg | grep -i firmware" to see what firmware files the kernel wants to load, and which ones it failed to load, and which ones it succeeded in loading. Given the firmware filename from the kernel, you can do a package file search to figure out which non-free package contains that firmware (if any). Then, once you know what package to install, you simply use "apt install packagename" to install it. When you say "(mate)", this tells me you most likely used one of the semi-official Debian Live installer images. Not the standard netinst image, and definitely not the unofficial netinst-plus-nonfree-firmware image. As such, you've got a system that's 100% Free (as in Libre), and does not include any non-free firmware or drivers. Sadly, almost all computers sold today require some non-free firmware to work properly. *Especially* laptops, and *MOST* especially wireless network interfaces. Wireless is the *worst* when it comes to Freedom. In order to get your non-free devices working correctly, there are a few steps to follow: 0) Make sure you actually have network repository lines for Debian in your /etc/apt/sources.list. If you did an install without a working network, you may not have a working sources.list file, because this part of the installer was written by people who are completely out of touch with the user base. 1) Add " contrib non-free" to each network repository line in /etc/apt/sources.list and then run "apt update". Steps 0 and 1 together would give you a sources.list that looks like this: deb http://deb.debian.org/debian buster main contrib non-free deb http://deb.debian.org/debian-security buster/updates main contrib non-free deb http://deb.debian.org/debian buster-updates main contrib non-free If your network didn't work during installation, you can just remove *everything* in the sources.list file and replace it with those three lines. Don't forget to run "apt update". 2) Identify the hardware. For most built-in devices, you can run "lspci -nn". Don't forget the -nn option, as this adds the PCI ID code to the output, and that's the *only* way to be absolutely sure what the hardware actually is. Vendors love to change the hardware but keep the model number the same, so you can't count on model numbers alone. For USB devices, you would normally use "lsusb". 3) Figure out what firmware and/or drivers are required for that hardware. This is the hard part. It's something you can Google for, given the PCI ID and model number and the key word "Debian". Other people who've dealt with your hardware in the past are likely to have posted about it *somewhere* on the Internet, and you can simply dig up their past advice. Or, you can post the "lspci -nn" or "lsusb" output for the device here, and it's pretty likely that someone will know how to deal with it. For your video issues, on a laptop this old, it's possible that you may only need to add some non-free firmware, and that may fix everything. Or, if it's an nvidia chipset, you may need to use a non-free driver instead of the Free driver. Or it could be one of those "Optimus" horror shows, with both an Intel chipset and an nvidia chipset, in which case you are screwed. We won't know until we see the lspci -nn output. For your wireless interface issues, you could need a whole non-free driver, or you could simply need firmware. Some of the drivers aren't even in Debian, and have to be installed from outside sources. Wireless is the *worst*.
Re: Are All Drives Installed .
> > Hello, I'm a newbie too, if you want to know if your drivers are installed look at the kernel logs with: $ dmesg If they're not you should see some error/warning messages. By default Debian will not install non free software like proprietary drivers. If this cause your issue, find the related driver and install it. For example, if you use: $ lspci You may find your network adapter named Atheros.* then install atheros-firmeware.deb. hope this help. Normally nobody can help you without knowing what are the devices you whose you want the drivers.
