@linux-aarhus Thanks for your reply and suggestion. Although this will be relatively complicated for me as I am more of an amateur at this, I am happy to try it. I’ve made a backup of the existing /etc/mkinitcpio.confas a precaution.
Modules in the current mkinitcpio are shown as
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES=(usbhid xhci_hcd)
MODULES=()
and I don’t see either i915 or xe. Should I therefore simply add xe to the above? in any specific order or place?
I had a brief look at the ArchWiki - Intel graphics you linked. Simply put. I need to spend s bit longer trying to understand it.
Thanks for your help and suggestion, Much appreciated. More so if it works

I am pleased to hear that I am not the only one experiencing this issue.
@linux-aarhus @BG405 I am not sure if this info is of any use but it might be. I tried another laptop that also runs Manjaro. I checked /etc/mkinitcpio.conf on this laptop and the modules section listed i915. I thought that may work. Basically, it’s the same. The difference is that I can see the laptop DE but get no sound and no picture from the browser. On trying to mirror displays on Gnome settings, settings closes.
I then retried the original laptop, not having made the suggested change to /etc/mkinitcpio.conf as suggested by @linux-aarhus . Once the HDMI is plugged in, I get the DE picture and the sound from the browser, Firefox, but no picture from the browser.
Both laptops run FF and although there have been numerous FF updates, I do not think that is the issue.

@linux-aarhus @BG405 I’ve not yet managed to resolve this issue. My recent attempts were:
- Roll back Manjaro to snapshot dated 27/07 using kernel 6.18 LTS, Firefox 153 and noted inxi -xv8. HDMI worked 100% and Gnome Settings display mirrored as before, i.e. as expected
- Rolled forward to Manjaro snapshot dated 19/08/26 using kernel 7.1, Firefox 154.0. HDMI did not work and Gnome Settings did not mirror or work and closed on 1 of 4 attempts to mirror.
The difference between the two inxi -xv8 prints, as far as I can establish, is shown in the print of 27/07/26 snapshot as follows
Display: unspecified server: X.org v: 1.21.1.24 with: Xwayland v: 24.1.13
compositor: gnome-shell driver: gpu: i915 display-ID: :0
note: <missing: xdpyinfo/xrandr>
The apparently important differences between the two snap shots is a) numerous Firefox upgrades, b) 2 x Manjaro updates and c) the kernel upgrade. My perception, rightly or wrongly, is that the ‘problem’ is the result of either a) or b).
Any comments or suggestions would be appreciated from anyone. Thanks

Is it possible that the upgrade of mutter from 50.3-1 to 50.4-1 may be causing my problem? If so would downgrading mutter be sensible?

After new updates in the last 24 hrs (< 20260823) I noted that mutter received and update. In my very limited experience & a little searching gitlab/mutter I see that a few changes to mutter in the last month or so may have affected my setup. Any thoughts on that? Is it worth changing the installed utter to an earlier version?

… mind you, I hate this laptop keyboard (flat keys, can’t feel for them). I opened a bottle of soda water and it sprayed over my USB keyboard, and killed it.
