[SOLVED] Secondary (external) monitor not being seen
Hey there. I am a new user and just installed having most everything setup how I want it. However, for some strange reason, although it is properly hooked up, the system (OS) does not see my external monitor. Obviously I can operate with a single monitor but I prefer to have the secondary monitor. Is there something I may be missing that I perhaps overlooked? I would think once hooked up and plugged into my system, Linux Mint would see that second monitor yes?
I have a Dell Inpiron 5400 AIO.
Thanks in advance for any assistance that could be provided.

Re: Secondary (external) monitor not being seen
Hi does this laptop has an ATI video card? I have similar problem with HUAWEI Mate-book 14 which has ATI Radeon video card and working software rendering mode. I have installed UBUNTU 20.10 for trouble shooting purposes and it worked it recognised the second monitor...

Re: Secondary (external) monitor not being seen
Your system does not have any graphics drivers installed because it is too new to be using the 5.4 kernel. The Linux Mint 20.2 "Uma" - Cinnamon (Edge, 64-bit) ISO has the 5.11 kernel and would have been a better choice for your very new hardware, but not everyone realizes it is available.

Thank you for the quick response. I did as you instructed and it was successful.

Re: Secondary (external) monitor not being seen
I just noticed your install has amdgpu drivers listed as unloaded. Does your system have AMD graphics somewhere? The specs I found for this computer indicate it has Intel and possibly Nvidia.

Check your video drivers
Your system is currently running without video hardware acceleration.
You may experience poor performance and high CPU usage.
Launch Driver Manager
When I launch the Driver Manager is scans my system and then gives me the message:
Your computer does not need any additional drivers.
But as I am new to Linux and still learning, I am unsure what to do or how to remedy that.
Re: Secondary (external) monitor not being seen
That is because the graphics drivers still did not load.

Re: Secondary (external) monitor not being seen
Two problems at the very start. One is your system is still using the 5.4 kernel and not the 5.11 kernel (the inxi -SMCGx you posted does show the 5.4 kernel installed) and you are booting in recovery mode which prevents the graphics drivers from loading.

Additionally, for some reason you created an xorg.conf file which is probably from where the amdgpu info is loading. Remove that file with
Then let us know why you are booting in recovery mode using the 5.4 kernel. You need to be booting normally and letting Mint install the highest number kernel which should be the 5.11 you installed.

Re: Secondary (external) monitor not being seen
Oh... lol, yeah it was the only thing I could do when I restarted all I got was a black screen with a blinking cursor up top. It did not boot back into LM. So I attempted a recovery. As for the xorg.conf, I have no idea what in the world that is. It does not look remotely familiar.SMG wrote: ⤴Sat Nov 27, 2021 1:00 pm Two problems at the very start.

I ran

The system actually did boot back into LM, but, because there was no graphics driver to install, it could not produce graphics. That is why you ended up with the black screen and the flashing cursor.
Using recovery mode so you can get into the system to get things fixed is the correct step to take, but it would have been helpful to let us know that is what happened and what you did to address the issue.

Re: Secondary (external) monitor not being seen
I apologize for that. When I booted up it did not seem any different so I assumed that it was back into normal mode. I really apreciate all of your assistance. This time it did allow me to boot as normal, AND the second monitor is now working. Was there any other commands that you would like for me to run? I want to make sure I completed all I need to even though the monitor is working.SMG wrote: ⤴Sat Nov 27, 2021 1:14 pmThe system actually did boot back into LM, but, because there was no graphics driver to install, it could not produce graphics.
