I'm totally confused!

Am I not using the dedicated AMD/ATI video card? Why? How I could starting using it?

What xorg package I can uninstall?

Thank you very much!

What is output from:

	inxi -GSxxza

What type cable is connected to which physical connector on the PC?

What is the Dell BIOS setting for video?

> What xorg package I can uninstall?

You can probably uninstall all of them and still be fine. Most likely the only
ones to keep would be xserver-xorg-video-amdgpu (probable preference) and
xserver-xorg-video-vesa (for rescue purposes). The intel doesn't require
xserver-xorg-video-intel, as it usually works as well or better with the only DDX
you don't see installed, modesetting, since as default it's not in a separate package.

That command only shows one of your cards, and not the other.  It's
simply not a command that gives you much useful information in this
situation.

> What xorg package I can uninstall?

What on earth makes you think you need to REMOVE software in order to get
the results you desire?

What even makes you think you're not already using the AMD card?

You need to check your X or Wayland logs before doing anything else.
Maybe you're already using the card and driver that you want to use.

If it turns out that you're not using the desired card, then there are
a few things you can look into next:

1) lspci -nn

Don't try to grep it or anything, because one of the cards doesn't show
up with the characters "VGA" in its output.  Just post both of the lines
from this command, one for each card, which will give us the PCI ID
to identify the hardware.

2) dmesg | grep -i firmware

See if the kernel is trying to load any firmware and failing.  If so,
you will probably want to install some of the non-free firmware packages
to support your hardware.  This may involve adding contrib and non-free
to your sources.list.

3) Google your PCI ID together with keywords like "debian" to see if there
   are any success stories for using your hardware on Debian.

Usually you are not the first person to attempt something.  Learn from
those who came before.

I forgot about the subject of firmware. It could be firmware-amd-graphics has not
been installed. Also needed are libdrm-amdgpu1 and xserver-xorg-video-amdgpu for
optimal operation with a Topaz XT.

Hi Felix and Greg, Thank you so much!

Here is more information.

I'm try to got 3 monitors in my debian bullseye. In this days/ weeks,
months, I have googled a lot to find any rule to tell me how I could to
put my third monitor to work. It is plugged in a DisplayLink FY
USB-DVI in this manner:

notebook usb3.0 port -> cable -> DisplayLink FY USB-DVI -> DVItoVGA
Adapter -> VGA cable -> Monitor AOC 511vw

I try this with the this instructions https://is.gd/Ijp1k1 and with the
DisplyLink install script (https://git.io/JvADQ). Not success.

So, I read in some place that can be a possible conflict with xorg
module. To figure out the solution, I'm try to uninstall all
unnecessary module. I'm in this point/step now.

I will continue to google for a solution, if there are anyone.

Thank you very much!

This is inxi output unlike any I have ever seen.

	driver: i915 v: kernel

is normal and expected, a result of using the i915 kernel module.

	X.Org 1.20.7 driver: i915 compositor

is unexpected. i915 is not an X graphics driver. Compositor is normally on the
next line. Normally one would expect that output to resemble this:

	X.Org 1.20.7 driver: modesetting unloaded: fbdev,vesa alternate: intel

Of course, these are for systems with only one GPU. Your laptop has dual GPUs, so
there should be a Device-2, which is missing from inxi output....

....but not from xrandr.

Apparently prime is in use to manage GPU use. As I have no experience with laptops
with dual graphics, and thus none with using prime, and neither with DisplayLink,
there is probably no more assistance for me to attempt here.

Should you desire to know the expected output from inxi -Gxx, and share it, the
inxi author has implemented a tentative fix to the recently discovered 6 year old
problem. This is his instruction:

	cd /usr/local/bin && wget -O pinxi smxi.org/pinxi && chmod +x pinxi

Probably this requires a root login to correctly execute. pinxi is the beta
version of inxi, so your test would be:

	pinxi -Gxx

The author is likely interested to see your result should you proceed.

https://github.com/smxi/inxi/issues/214 is the relevant bug report about this.
