Question is it possible that my iGPU is fried or something else is wrong

[munish259272]

I have been using RHEL 9 as a desktop for over a year
mother board : TUF GAMING B560-PLUS WIFI
- CPU is set as primary in bios and in multi-monitor mode
- HDMI from the motherboard is connected to the monitor
CPU : intel 10900
GPU : rtx 3060 ( connected to the same monior via display port )

one evening while doing dnf update the system hangs while connected to the HDMI port and i am no longer able to get into GUI mode after a lot of struggle i find out that i can only use the display port ( connected to the discrete GPU ) to access the GUI and only the text mode via HDMI ( connected to the onboard CPU ).
This led me to think that there is something wrong with my iGPU.

I have tried booting fedoa, redhat, ubuntu and none of them go into GUI mode over HDMI.
Strangely, windows 10 pro boots into GUI mode over HDMI , and also ubuntu boots into GUI mode when graphics safe mode is selected.

Please help

EDIT : i just disconnected the HDMI cable ( connected to the mother board ) so that only GPU is used and i still cannot boot into GUI using usb.

Not sure what's going on

Do you still have ssh access? If so, then with the monitor on the failed port during boot, see what the "/var/log/Xorg.0.log" shows (you could attach it to the forum as a .txt file). If you don't have ssh access, then you could boot once on the bad monitor connection, followed by booting on the working port; run this command to find the most recent "old" log:
ls -ltr /var/log/Xorg.*.log.old | tail -n 1

This would allow you to use the "old" log if the timestamp is valid.

Also, it is quite possible that you used to have the NVIDIA driver and files, but the update mixed in some Mesa content which is not compatible. Because the GUI works on the other port, but that port uses a different driver, the odds are reasonably high that it was a driver mixup.

Btw, I don't necessarily have it correct as to which port works or fails. Might need to "swap" some of the comments if I have it reversed.
