No external video output after suspend on Intel Xe Graphics (TGL GT2)
On a Lenovo X1 Nano using
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:9a40] (rev 01)
xrandr shows an external output if plugged in. However as soon as enabling it and suspending the device, no external outputs are visible anymore.
I have attached an xorg.0.log from a case after which it does not appear anymore.Xorg.0.log
This has been the case with various kernels, including 5.15.0.
Currently I am using the modesetting driver, but I recall I had the same behaviour with the intel driver.
Is there any kernel command line or xorg option to fix this behaviour?
