iGPU not detected and display shows as unknown after update

System details:
Framework 16
Ryzen 9 7940HS w/ 780M graphics
RX 7700S dGPU enclosure
6.12.8 Kernel
KDE, SDDM

Greetings all, relatively new Arch user here.

I've run into this issue today which I have spent far too long trying to puzzle out - after and update and (accidental) restart due to power loss while I was away from my laptop (I left it unplugged) I came back to a laptop with a messed up desktop (scaling all wrong, icons defaulted to along the top of the screen, system monitor widgets to minuscule size).

After a significant amount of poking and prodding around I discovered that my system wasn't recognising my iGPU and didn't seem to be using it either (but I can't tell, only infer)
Additionally within Display Configuration my laptop screen now shows up as 'Unknown-1' and is locked to 60Hz (should be able to go up to 165Hz)

Initially thinking that this was a graphics issue or general 'thing that went wrong' I downgraded linux, linux-headers, and mesa using downgrade (all of which were affected by the update I did) but that didn't fix the issue so I reverted.

Furious searching and topic trawling later I went through journelctl with grep and searched for 'GPU', and I noticed that there was a line saying about an 'unsupported GPU' (output of query .

My system is also running quite slow and the fan is going balistic, which I assume to be the fault of the iGPU not doing it's job.

I don't know enough about how Arch or linux in general works, and I've already spent most of the afternoon on this, so I thought it time to ask for help. Any and all knowledge is appreciated, please let me know if there is any other information I can provide that would be usefull.

Also the dGPU firmware and BIOS is up to date.

EDIT1 - video playback in youtube on firefox is rather stuttery and low quality (defaults to 480p rather than 1080/1440/1600 like it used to), the CPU is also nearly maxing out watching videos for some reason as well, I don't know why but I'd guess it's due to the iGPU issue?

If https://wiki.archlinux.org/title/Pacman … c_packages doesn't help please post back with details of your graphics hardware & drivers:

lspci -knn -d ::03xx

EDIT: and please share a full journal, excepts miss context. Thanks.

Re: iGPU not detected and display shows as unknown after update

Is there any filesystem corruption? Have you tried reinstalling the linux-firmware package?

Did the laptop shut down during the update or afterwards?
