Good Morning.
I have now installed linux cinnamon as a dual boot on a disk partition.
The main monitor is not showing, but I think it is connected as you can see from the images.
Only if I turn off the main monitor (it is only possible to do this while not in linux, that is, before entering linux) is it possible to check the panels on the right monitor.
What should I do?

Re: Main monitor not displaying
Obviously I've been researching and the solutions I found, like installing nvidia drivers or changing grub file, for example, didn't work.
Re: Main monitor not displaying
How would we know if that might even apply if you do not give us the information requested in Section 5 of READ: How To Get Help!?
Please give us information about your install by entering this command in a terminal:
inxi -Fxxxrz
Click

from the mini toolbar above the textbox where you type your reply and then place your cursor between the code markers and paste the results of the command between the code markers [code]

. This will let us know how Mint sees your hardware.A woman typing on a laptop with LM20.3 Cinnamon.
Re: Main monitor not displaying
Sorry guys. I didn’t put this point because I can only run the terminal with the monitor off so I thought it wouldn’t make sense.
The monitor on the left is connected buy HDMI, the mid and the right one is connected by DisplayPort.
I run the code below with the monitor off.

Re: Main monitor not displaying
What makes you think it is connected? What criteria are you using to say that? Remember that we are not there, so the more description you can give us, the more likely we can help you.
I do not understand what this means. Why do you say it is not possible to turn off the main monitor while is Mint? Do all three screens go black if you do that? Is the only way for the two outer screens to display an image is when you turn off the middle monitor before booting Mint?
When you ran the live session of Mint to test it before you installed, were you able to see images on all three screens?
I am not clear what "I can only run the terminal with the monitor off" means.
Is this the latest BIOS/UEFI available for your motherboard?

Just an FYI: This is an extremely small Mint installation. Normally, we recommend a root partition of 30-50GB when there is a separate home partition. Your system is on the smaller side of this recommendation with no additional home partition.

Re: Main monitor not displaying
I updated the Nvidia drivers and now the main monitor is the only one that works and is recognized, the other monitors do not appear when I put the command "inxi -Fxxxrz". The monitor that works have a bad resolution and it was not possible to change it through the "dysplays" menu.

That sounds like the Nvidia driver files may not have loaded before X Server did.Dr33 wrote: ⤴Fri May 14, 2021 4:36 am I updated the Nvidia drivers and now the main monitor is the only one that works and is recognized, the other monitors do not appear when I put the command "inxi -Fxxxrz".

In that type of situation, try doing Ctl-Alt-Backspace to restart the X Server. If that works, then a more permanent solution is to do the change in this post [SOLVED] NVIDIA driver failing sometimes on boot ("no hardware acceleration"). Let us know if the fix roblm recommends in the second post addresses the issue for you.
