I am new to linux. I have installed ubuntu in the past, but that was years ago. I wanted to try Fedora this time around. How to I enable my second monitor? I went to the cog, clicked on “displays” and there isn’t an option for dual monitor setup. I am using AMD Radeon graphics card, I tried to install drivers but the documentation I found said that the drivers are already installed by default. So, I tried updating my computer and still no option for dual monitors.
Which Fedora version do you use. Settings probably depend on which DE you are using.
What video card do you use and with which drivers? Do you use X11 or Wayland?
For me using KDE it has always been automatic:
Connect the 2nd screen and switch it on, then boot the PC.
You should now have 2 monitors which you have to setup: the external one as a copy of the first, as an extension to the left of the first or to the right. This depends on which side of the 1st monitor you have placed the 2nd.
Fedora Workstation 40
GPU: Radeon RX 6600
Wayland
I don’t see any options to setting either monitor as first or second.
Also typing xrandr --query into terminal only shows one monitor.
It looks like it might be a known problem with that particular hardware:
Edit: If it is a problem with power management, as suggested in that post, then adding amdgpu.aspm=0
as a kernel parameter might be another workaround.
I don’t know Gnome at all, never used it, never seen it, So I can’t help you there.
But let’s see if the idea @glb had works for you. And maybe others can help as well.
