Monitor not detected in Zorin OS 17.3

var_zorin · September 19, 2025, 1:50pm

Hi,

I just installed zorin os 17.3, I have both amd processor and graphics, The GNOME display manager is not detecting my monitor, I am trying to connect via HDMI port.
6.8.0-83-generic is the kernel version I am using.

Did you try to turn round the cable? Some HDMI cables only work in one direction.
Do you have a multi monitor setup or is this the only one monitor?

Ponce-De-Leon · September 19, 2025, 2:10pm

Welcome to the Forum!

Was the Monitor detected when You tried it and during the Installation? Did You tried different HDMI-Ports? Do You use a Hub?

var_zorin · September 19, 2025, 2:28pm

I have only one monitor, The same HDMI cable works fine when I boot into windows.

var_zorin · September 19, 2025, 2:29pm

No I dont remeber monitor working during installation, I think I had not plugged it in. I use a HDMI splitter, Like I said, The same setup works when I boot into windows

Aravisian · September 19, 2025, 2:33pm

HDMI splitter - this may be the cause. Can you test without the splitter?

var_zorin · September 19, 2025, 2:37pm

No, Its not working even without the splitter

Aravisian · September 19, 2025, 2:45pm

With the monitor plugged in and turned on, what is your terminal output for:

lspci -nnk | grep -A3 VGA

Are you logging in on Wayland or Xorg?

var_zorin · September 19, 2025, 3:04pm

I tried logging in via wayland and tried the above command, Below is the output

pcilib: Error reading /sys/bus/pci/devices/0000:00:08.3/label: Operation not permitted

Also, My current laptop display shows as Unknown 24"

Aravisian · September 19, 2025, 3:08pm

Sorry... try it with Sudo

sudo lspci -nnk | grep -A3 VGA

If on Xorg, you can make use of xrandr

xrandr --listmonitors

var_zorin · September 19, 2025, 3:12pm

varun@Kobe:~/Desktop$ echo $XDG_SESSION_TYPE

Aravisian · September 19, 2025, 3:18pm

Since you are on Wayland, it will only show the Xwayland -

Xrandr does not work on Wayland (OR Wayland does not work with xrandr)
You must be on Xserver, X11, Xorg for Xrandr to work.

var_zorin · September 19, 2025, 3:23pm

Switched to x11,

Aravisian · September 19, 2025, 3:27pm

This shows a generic fallback placeholder - likely your HDMI port.
What is your AMD card?
Unless you manually installed a driver, I know you are using the AMDGPU that is included in the 6.8 kernel.

var_zorin · September 19, 2025, 3:32pm

Advanced Micro Devices, Inc. [AMD/ATI] Device 1114 (rev c2)
Subsystem: ASUSTeK Computer Inc. Device 3c88
Kernel modules: amdgpu

Does this help? Its likely Radeon 800M series one.

Aravisian · September 19, 2025, 3:37pm

Yes, that is a newer card. So we know it is not due to legacy drivers. And the AMDGPU module is recognized for the kernel. Is that driver in use?

Please paste the full output of

sudo lspci -nnk | less

I realize you may get an operation not permitted warning - that can be ignored. We are looking for the lines that follow that.

This shows Display Controller (generic) instead of VGA Display Controller. It shows the module present but not in use.
So your driver is not loaded.

Since it should be, you could try module prober on it (modprobe), but I think it is more likely that you need to upgrade your kernel.
First we will try

sudo apt update && sudo apt install linux-firmware linux-generic-hwe-22.04

If no good after a reboot, I recommend at least the 6.12 kernel.

Secure boot

Secure boot operates by checking initializing programs against a Microsoft Signed list.
Microsoft is terrible about getting around to signing off on Mainline kernels.
(And Nvidia drivers.)
So, to install a newer kernel, I recommend disabling Secure Boot in BIOS.
