What is the model of the other? What is its native resolution?

There log file named Xorg.0.log either in /var/log/ or in ~/.local/share/xorg/. We need to see what's in it. Please find it, then when you know its location, use its <location> in this command

Code:

sudo pastebinit <location>/Xorg.0.log

and input here the resulting URL. Also run these commands

Code:

xrandr --listproviders
inxi -GxxM

and paste the resulting output here. If you receive an error message because inxi is not found, do

Code:

sudo apt install inxi

and try again. Only do these after you have plugged in the second display and then unplugged it if necessary to finish.

Hi anaturelover,

Something you haven't mentioned... What are the monitors plugged into? A separate graphics card, or do you have two video outputs on your motherboard? With the motherboard you may have an "either one or the other" sort of set up due to shared video memory.

I'm running Mint Cinnamon 18.3 with a Nvidia Quadro 600 which came with my reconditioned HP Z400 workstation. It comes with one display port and one DVI-I port. I bought adapter cables to allow two monitors to be connected and must admit I was quite surprised that both monitors worked! Yes, I DO use the Nvidia drivers suggested by Mint's driver manager and have my desktop spread across both screens using the Nvidia server settings app. Very useful! I can monitor my 3D printer on one while designing stuff or watching Netflix on the other.

Anyway... That's my experience, hope it's useful.

Play Bonny!

meanwhile linux asked me to install the recommended driver for the gpu NVIDIA GeForce GTX 260 so i did. after that I only can see the grob, it does not open linux there is a black screen with a small _ line like that_. maybe i iterrupted the driver installation by rebooting it while it was installing? i dont know for sure.. iwrite from windows now.

If you did interrupt NVidia driver installation it will probably easier to install again than to repair. An abort like this in combination with using some other display to install that driver that may not match either of your mismatched 1440x900 or 1920x1200 displays is a recipe for multiple problems in need of solving.

Before starting over there are things to try. At the Grub menu, choose the last choice, failsafe or something similar. If you do this, can you reach a text mode shell login prompt? If so, you can try removing the NVidia driver, then leaving it uninstalled until everything else is verified working, or reinstalling without allowing any interruption. Try this and report back if you like. Otherwise, just start over, and don't be in a rush to install the proprietary driver that you might not even need.

Both of FOSS DDX (X drivers, modesetting & nouveau) are capable of driving two displays automagically. This one is using the upstream default DDX, modesetting:

To answer the question you erased, just a few:

I mean from HD. Does your Grub have no second or third selection to choose? What I meant is usually the last selection. Your picture doesn't show what I would expect from your choice. Try rebooting again, and at the grub menu, strike the E key. Then move the cursor to the end of the line that starts linu and type

Code:

 vga=791 nomodeset

then F10. Does the resulting boot present a shell login prompt?

You got the E key right, but from the wrong starting point. On the first grub screen you need the highlight on the top selection before striking the E key.. Then you should see a line that starts with linu to which you will append.

In another matter, please select the second from the top (Advanced Options....) and get a picture of the result to upload. It might have one or more useful options.

This one only tells us you're working in apparently limited space. Best to remove the pile in front of the screen before taking any more pictures.

This one didn't fit everything I need to see on the screen, which is below the fi line. Without the scroll down, you wouldn't have seen it either. Scroll down, then you should be able to follow the instruction in comment #8.

Possibly in part because you blocked the bottom of the screen, it's unclear to me why you are on the Grub shell prompt screen. Trying to do anything from it we want to avoid.

hi here is what i see when cinamon first is highligted and press e ( here is what we see when scrolling down)https://www.cjoint.com/c/JAxdcAOJdBH

You uploaded the same image twice, these two. That's OK. In it where you see "handoff" is where you need to append as instructed in comment #8. Does the resulting boot present a shell login prompt? Just use the arrows, home and end keys until you reach the spot. Type

Code:

 vga=791 nomodeset

then F10.
