Dual monitors wont work!

Post by buckeyecelt » Fri Aug 02, 2019 3:42 pm

Ok I am new to Linux.

I am trying to get a second monitor up and running on an older PC that I was runnning Windows Home Server on.

This is an integrated chip set and I am trying to use an HDMI and a DVI.
The DVI is working, the HDMI is not.

I cannot get the second monitor to even be detected.
In reading through the forums I tried using ARandR with no luck as well.

Any help would be appreciated!

Here is my system info...

Hi,

I'm also new to Linux Mint and was having this problem as well. I had both monitors plugged in but 1 wasn't being recognized. All I had to do was unplug and re plug in my 2nd monitor and Linux noticed it and started working.

Have you verified that the HDMI connected monitor and cable work correctly on another system?

Is the monitor using any adapter or switch?

What is the brand and model number of that monitor?

Use these commands and post the output: xrandr --prop and ls /sys/class/drm

Ok, so I can get either monitor to work, but not at the same time...
If I unplug one, then the other works and visa versa.

Ok, so I had an old cheap video card that I threw in the machine and all seems to be working now...

The onboard graphics apparently didnt play as nice as they did in windows...

It appears that you were connecting the second monitor to the motherboard’s VGA port.

If you want to try using the integrated graphics, then test this kernel parameter by editing the kernel command line. The effect will only last for one session. At the GRUB boot menu select the correct line but don’t press Enter. Press the “E” key to edit. If no menu shows, then hold down the shift key while starting. Use the Down arrow key to go down to the line that starts with:
linux /boot/vmlinuz.............ro quiet splash $vt_handoff

Go to the end of the line. Add a space and then type this parameter: video=VGA-1:e

Press F10 to start your system.
