the display doesn't appear after suspend, i915

[Dik]

System: Lenovo T470s
Kernel: 5.4.0-97-generic #110-Ubuntu SMP

After S3 suspend and resuming the external display doesn't work. C-A-F1, C-A-F7 solves the problem.

The regression appears 2-3 weeks ago after update.

install 'linux-generic-hwe-20.04' and then you'll get a newer kernel

does it fix this?
