I've been having trouble with an intermittently flickering screen on my laptop for the past few weeks. About half the time, it's minor, just flickering for a few seconds, but it can get worse, lasting for a minute or two and blanking large (nearly all) of the screen. The worst incidents will end with the following in the log:
Jul 24 15:44:50 homelap7 kernel: i915 0000:00:02.0: [drm] HPD interrupt storm detected on connector eDP-1: switching from hotplug detection to polling
After this, the flickering stops.
This is just a guess, but have you tried adding "i915.enable_psr=0" to the kernel parameters at boot (hit 'e' when the bootloader shows up, add the above snippet right after '...splash=silent quiet' on the same line)? There have been issues with the i915 graphics flickering that have been helped with this, perhaps at the cost of somewhat higher power usage [see e.g. < https://wiki.archlinux.org/index.php/Dell_XPS_13_(7390)>].
